Japanese Unexamined Patent Publication No. 2018-175635

Regarding card games such as those mentioned above, there is a desire for people other than players to watch the match. In this regard, more by specifying the type and state of the card placed in the game field by the system and displaying an image showing the current state of the game field on the display unit for the audience based on the specific result. People and people in remote areas will be able to watch card game matches.

As a method for specifying the type and state of the card placed in the game field by the system, a shooting unit for shooting the game field is set up, and the type or state of the card placed in the game field is determined by the shooting unit. It is conceivable to adopt a method of specifying from the captured image. However, there are cases where the type and state of the card placed in the game field cannot be specified (or is difficult to specify) from the captured image.

For example, in general, in a card used in a card game, a card placed on the game field has a front surface having an appearance according to the type of the card and a back surface having a common appearance regardless of the type of the card. When specifying the type of the card from the captured image, the type of the card is specified from the surface of the card shown in the captured image. However, according to the rules of a card game, the card may be placed on the game field in an inverted state, and in such a case, the surface of the card is not reflected in the captured image, so that the type of the card cannot be specified from the captured image.

Further, for example, it may be difficult to identify the type and state of the card placed on the game field from the captured image due to the influence of ambient light or the like. Among the cards used in card games, there are multiple types of cards that have undergone special processing (for example, holograms), and for such cards, the type and state of the card can be specified from the captured image. It's difficult to do.

In addition, in order to be able to identify (or easily identify) the type and state of the card placed in the game field, it is conceivable to provide a special mechanism for that purpose in the card itself, but in this case, the existing card Problems such as the inability to use (cards without the above mechanism) in the game occur.

The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to use an existing game object for use in a game, and to provide a game medium placed on an object surface in the real world. The purpose is to provide an accommodation and an object capable of identifying (or facilitating) the type or condition.

In order to solve the above problems, the housing according to one aspect of the present invention is a housing for accommodating individual game media used in a game played by using a game medium placed on a target surface. It includes an IC tag for holding specific information for specifying the type or state of the game medium placed on the target surface in a state of being housed in the container.

Further, the object according to one aspect of the present invention is an object that is housed in an container together with individual game media used in a game played by using a game medium placed on a target surface. Includes an IC tag for holding specific information for specifying the type or state of the game medium placed on the target surface in a state of being housed in the game medium.

Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings.

[1. First Embodiment] The system according to the first embodiment of the present invention will be described.

FIG. 1 shows an example of the configuration of the system 1 according to the first embodiment. The system 1 is a system related to a game played by using a real object placed on an object surface set in the real world. As will be described later, the system 1 includes a function as a specific system for specifying the type and state of an object placed on the target surface in the above game. In addition, the system 1 also includes a function as a display control system for displaying a display related to an object placed on the target surface on the target surface in the display means.

For example, a card game played using cards corresponds to an example of "a game played using an object placed on a target surface". In the following, a competitive card game (trading card) in which a player sets a deck by combining arbitrary cards from among the cards owned by the player according to a predetermined rule and uses the deck to play against other players. The system 1 according to the first embodiment will be described by taking the game) as an example.

[1-1. Outline of the card game] Before explaining the configuration of the system 1, the outline of the card game will be explained.

2A and 2B show an example of a card used in a card game. The card 60 is a rectangular object and is formed of a material such as paper.

FIG. 2A shows an example of the appearance of the surface 61 of the card 60. In FIG. 2A, as an example of the card 60, a character card, which is a card indicating a character, is shown.

As shown in FIG. 2A, information about the card 60 is written on the surface 61 of the card 60. Since FIG. 2A shows a character card, information about the character is written on the surface 61. For example, the surface 61 includes parts P1, P2, P3, P4, P5. Part P1 indicates the name of the card 60 (character). Part P2 is an image of a character. Part P3 shows a description of the character. Part P4 shows the character's offensive power (ATK) and defensive power (DEF). Part P5 indicates a card ID. The card ID is information that identifies each card type. For example, the appearance (design, text, etc.) of the surface 61 of the card 60 is different for each card type, the card ID of the card 60 having the same appearance of the surface 61 is the same, and the card 60 has a different appearance of the surface 61. The IDs are different. For example, the card IDs of the cards 60 indicating different characters are different. When there is only one type of card 60 indicating a character with the same name, the card IDs of the cards 60 indicating the same character are the same. On the other hand, when there are a plurality of types of cards 60 having different appearances on the surface 61 as cards 60 indicating characters having the same name, the card IDs of the plurality of types of cards 60 are different. For example, when there are a plurality of types of cards 60 having different rarities or ranks as cards 60 indicating characters with the same name, the card IDs of the plurality of types of cards 60 are different.

In FIG. 2A, an example of a character card is shown as an example of a card 60 used in a card game, but in a card game, a card 60 indicating a non-character is also used. For example, a magic card indicating magic or a trap card indicating a trap is used. Like the character card, the surface 61 of the magic card or the trap card has information about the magic or the trap.

FIG. 2B shows an example of the appearance of the back surface 62 of the card 60. The back surface 62 of the card 60 has an appearance common to all cards used in card games. That is, the back surface 62 of the card 60 has a common appearance regardless of the type of the card 60. Therefore, the type of the card 60 cannot be specified from the appearance of the back surface 62.

The card game progresses by placing the card 60 on the game field by the first player and the second player who play a match. FIG. 3 shows an example of the game field F. As shown in FIG. 3, the game field F includes a first player field F1, a second player field F2, and a shared field F3.

The first player field F1 is an area for placing the card 60 of the first player. The first player field F1 includes a plurality of zones Z1 to Z14.

For example, zone Z7 is an area for placing the deck of the first player as a deck. Here, the "deck" means a bundle of cards 60 in which the cards 60 owned by the player are arbitrarily combined according to a predetermined rule when playing a card game, and the "deck" is a "deck". , Means a deck that has been shuffled and placed face down. The first player can draw a card from the deck placed in Zone Z7 and add it to his or her hand.

Further, the zones Z2 to Z6 and Z8 to Z13 are areas for the first player to place an arbitrary card 60 selected from his / her own hand.

For example, zones Z9 to Z13 are areas for the first player to place a character card from his / her own hand. The first player is in a state where the character can be used for battle (attack, etc.) by placing the character card in the zones Z9 to Z13 from his / her hand.

Further, for example, zones Z2 to Z6 and Z8 are areas for the first player to place a magic card or a trap card from his / her own hand. The first player can generate a magic or trap effect in a card game by placing a magic card or a trap card from his or her hand in zones Z2 to Z6, Z8.

Further, for example, the zone Z14 is an area for placing a character card of a defeated character, a used magic card, or a trap card. Zone Z1 is an area for storing a bundle of special cards 60 that can be placed in zones Z29 and Z30 of the shared field F3. The first player can place the card 60 in the zone Z29 or Z30 from the bundle of special cards 60 placed in the zone Z1 under predetermined conditions.

The second player field F2 is an area for placing the card 60 of the second player. The second player field F2 includes a plurality of zones Z15 to Z28. Since the meanings and roles of the zones Z15 to Z28 are the same as those of the zones Z1 to Z14 of the first player field F1, the description thereof will be omitted.

The shared field F3 is a shared area between the first player and the second player. The shared field F3 includes a plurality of zones Z29 and Z30, and both the first player and the second player can place the card 60 in the zones Z29 and Z30 under predetermined conditions.

In the following, when it is not necessary to distinguish each of the zones Z1 to Z30, these are collectively referred to as "zone Z".

Card games are run on a turn-based basis. That is, in the card game, the turn of the first player and the turn of the second player are alternately and repeatedly executed.

On the first player's turn, the first player draws a card 60 from a bundle of cards 60 placed in zone Z7 (the first player's deck) and adds the drawn card 60 to his or her hand. Under certain conditions, the first player may place any card 60 from his or her hand in zones Z2 to Z6, Z8 to Z13, or zone any card 60 from a bundle of special cards 60 placed in zone Z1. It is placed on Z29 and Z30, and its own card 60 placed on the game field F is used to attack the second player and the like.

Similarly, on the second player's turn, the second player draws a card from a stack of cards 60 placed in zone Z21 (the second player's deck) and adds the drawn card 60 to his or her hand. Under certain conditions, the second player may place any card 60 from his or her hand in zones Z16 to Z20, Z22 to Z27, or zone any card 60 from a bundle of special cards 60 placed in zone Z15. It is placed on Z29 and Z30, and its own card 60 placed on the game field F is used to attack the first player and the like.

In a card game, a plurality of types of card placement formats are defined, and the presence or absence or content of the influence of the cards on the progress or result of the card game changes depending on the placement format.

FIG. 4 is a diagram for explaining a character card arrangement format. As shown in FIG. 4, in the card game, three types of arrangement formats of the front side attack display, the back side defense display, and the front side defense display are defined as the arrangement format of the character card.

The "face-up attack display" is a state in which the character card is placed face up and vertically. "Face-up" is a state in which the card 60 is placed so that the surface 61 of the card 60 can be seen by the player. In other words, "face-up" means that the card 60 is placed so that the back surface 62 of the card 60 and the game field F face each other. Further, the "vertical orientation" is a state in which the card 60 is placed so that the card 60 looks vertically long when viewed from the player. In other words, the "vertical orientation" is a state in which the card 60 is placed so that the long side direction of the card 60 is parallel (or substantially parallel) to the vertical direction of the game field F. By placing the character card in the face-up attack display, the player can perform a battle based on the attack power (ATK) of the character card.

The "backside defense display" is a state in which the character card is placed face down and sideways. "Face-down" is a state in which the card 60 is placed so that the back surface 62 of the card 60 can be seen from the player and the front surface 61 of the card 60 cannot be seen. In other words, "face down" is a state in which the card 60 is placed so that the surface 61 of the card 60 and the game field F face each other. Further, "sideways" is a state in which the card 60 is placed so that the card 60 looks horizontally long when viewed from the player. In other words, "horizontal" means that the card 60 is placed so that the long side direction of the card 60 is parallel (or substantially parallel) to the horizontal direction of the game field F. By placing the character card in the back side defense display, the player can perform a battle based on the defense power (DEF) of the character card.

The "front side defense display" is a state in which the character card is placed face up and sideways. By placing the character card in the front side defense display, the player can perform a battle based on the defense power (DEF) of the character card.

When placing the character card on the game field F, in principle, the player can select either the front side attack display or the back side defense display as the placement format. The character card placed in the back side defense display changes to the front side defense display when it is attacked by an opponent (1). When the player places the character card in the back side defense display, the opponent attacks the character card without knowing the name and performance (attack power, defense power, etc.) of the character card. At the time of attacking, the name and performance of the character card will be known. In addition, the character card placed in the back side defense display may change to the front side defense display when the effect of a specific magic card is activated. In addition, the player can change his / her character card placed in the back side defense display to the front side attack display (2). Further, the player can change the arrangement format of his / her character card placed in the game field F between the front side attack display and the front side defense display (3).

Similarly, in a card game, a plurality of types of placement formats are defined as placement formats for magic cards or trap cards. For example, there are two types of arrangement formats for magic cards or trap cards: front side display and back side display. "Face-up display" is a state in which a magic card or a trap card is placed face up and vertically, and a state in which the effect of the magic or trap indicated by the magic card is activated. On the other hand, "back side display" is a state in which the magic card or the trap card is placed face down and vertically, and the effect of the magic indicated by the magic card or the trap indicated by the trap card is awaited. be. The magic card or trap card placed on the back side changes to the front side display at any timing of the player or when the predetermined activation condition is satisfied, and the effect of the magic or trap indicated by the magic card is activated. do. If the player places a magic card or trap card in the back side display, the opponent proceeds with the battle without knowing the name or effect of the magic card or trap card, and when the magic card changes to the front side display, the magic card Or you will know the name and effect of the trap card.

The player selects or changes the card arrangement format in order to make a deal with the opponent in consideration of the characteristics of the arrangement format as described above.

In a card game, when the points (life points) of the second player, which are reduced by the attack from the first player to the second player, become zero, the first player wins and the second player loses. On the other hand, when the points (life points) of the first player, which are reduced by the attack from the second player to the first player, become zero, the second player wins and the first player loses.

In this embodiment, the card 60 is used in a state of being housed in a sleeve. FIG. 5 is a diagram for explaining the sleeve. As shown in FIG. 5, the sleeve 70 is an accommodating body for accommodating one card 60. The sleeve 70 is a rectangular and bag-shaped object having three sides bonded to each other and the remaining one side as an opening, and the card 60 is housed in the sleeve 70 from the opening. The sleeve 70 is formed of a synthetic resin such as polypropylene. For example, the sleeve 70 is provided (sold, etc.) separately from the card 60.

The sleeve 70 has a front surface portion 71 and a back surface portion 72. The surface portion 71 is a surface portion (opposing surface portion) that faces the surface 61 of the card 60 when the card 60 is housed in the sleeve 70. The back surface portion 72 is a surface portion (opposite surface portion) on the side opposite to the front surface portion 71, and is a surface portion that faces the back surface 62 of the card 60 when the card 60 is housed in the sleeve 70. As shown in FIG. 5, in the card 60, the front surface 61 of the card 60 and the front surface portion 71 of the sleeve 70 face each other (in other words, the back surface 62 of the card 60 and the back surface portion 72 of the sleeve 70 face each other. (In a way) it is housed in the sleeve 70.

The surface portion 71 of the sleeve 70 is transparent, and the surface portion 61 of the card 60 housed in the sleeve 70 can be visually recognized from the outside of the sleeve 70 via the surface portion 71. It should be noted that the entire surface portion 71 does not have to be transparent, and if the surface 61 of the card 60 housed in the sleeve 70 can be visually recognized from the outside of the sleeve 70, a part of the surface portion 71 (for example, an end portion). ) Does not have to be transparent. On the other hand, the back surface portion 72 of the sleeve 70 is opaque and has the same appearance as the back surface portion 72 of the other sleeve 70. That is, the back surface portion 72 has an appearance common to all sleeves 70. Therefore, the individual sleeves 70 cannot be distinguished from the appearance of the back surface portion 72. For example, the back surface 72 has the same appearance as the back surface 62 of the card 60.

The sleeve 70 includes an IC tag 73 (RFID tag). The IC tag 73 is a device having a function of communicating via radio waves such as radio waves. For example, the IC tag 73 includes an IC chip and an antenna, receives a signal transmitted wirelessly from the IC tag reader via the antenna, and wirelessly receives information stored in the IC chip in response to the reception of the signal. It is a passive type IC tag that returns to the IC tag reader via. The IC tag 73 may have a function of writing and storing information received from the IC tag writer via the antenna on the IC chip. Further, the IC tag 73 is not limited to the passive type IC tag, and may be an active type IC tag.

For example, the IC tag 73 is provided at a position other than the surface portion 71 of the sleeve 70 so that the surface 61 of the card 60 is not hidden by the IC tag 73 and becomes difficult to see. In this embodiment, the IC tag 73 is provided on the inner surface of the back surface portion 72 of the sleeve 70. For example, the IC tag 73 is attached to the inner surface of the back surface portion 72 by a seal or the like. The antenna of the IC tag 73 may be printed on the inner surface of the back surface portion 72. Further, the IC chip of the IC tag 73 stores a tag ID which is information that uniquely identifies each IC tag 73.

Since the back surface portion 72 of the sleeve 70 is opaque, the IC tag 73 cannot be visually recognized from the outside of the sleeve 70. Therefore, even if there is a difference in the installation position of the IC tag 73 between the sleeves 70 or an individual difference in the IC tag 73 itself, the difference is used as a clue to the individual from the back surface portion 72 of the sleeve 70. The sleeve 70 is secured so that it cannot be distinguished.

If there is no difference in the installation position of the IC tag 73 or the IC tag 73 itself, or if such a difference can be ignored and the IC tag 73 can be visually recognized from the outside of the sleeve 70, there is no particular problem. The back surface 72 of the sleeve 70 may be transparent. Further, when both the front surface portion 71 and the back surface portion 72 of the sleeve 70 are made transparent, the inner side surface of the front surface portion 71 may be provided with the IC tag 73.

When the IC tag 73 is attached to a part of the back surface portion 72 of the sleeve 70, the thickness of the installation portion of the IC tag 73 becomes larger than the other portions, and the stability when a plurality of sleeves 70 are placed on top of each other becomes stable. It may be damaged. Therefore, in order to make the thickness of the sleeve 70 uniform (or substantially uniform), for example, the thickness of the portion of the back surface portion 72 other than the installation portion of the IC tag 73 is set to the thickness of the IC tag 73. The thickness may be the same as the thickness, or the IC tag 73 (antenna) may be arranged over the entire inner surface (or a wide range) of the back surface portion 72.

In this embodiment, the card 60 is used in a state of being housed in the sleeve 70. The sleeve 70 plays a role of protecting the card 60 from damage and the like, and also plays a role of specifying the type and state of the card 60 placed in the game field F, as will be described later. In the following, the card 60 housed in the sleeve 70 will be referred to as “card 60S” for convenience in order to distinguish it from the card 60 alone. In other words, when the card 60 is housed in the sleeve 70, the card 60 and the sleeve 70 are regarded as one object and are described as "card 60S".

[1-2. System Configuration] Returning to FIG. 1, the configuration of the system 1 according to the first embodiment will be described. As shown in FIG. 1, the system 1 includes a game board 10, a photographing device 30, an information processing device 40, and a display terminal device 50.

The game board 10 is a board on which cards are placed by a first player and a second player who play a card game. For example, the game board 10 is arranged on a table 2 on which the first player and the second player sit facing each other.

The game board 10 includes a housing 11 and a mat 12 mounted on the upper surface of the housing 11. A game field F (zones Z1 to Z30) is drawn on the mat 12. The housing 11 and the mat 12 may be integrally formed. That is, the game field F may be drawn on the upper surface of the housing 11. In the following, placing the card 60S on the game board 10 (mat 12) is described as "putting the card 60S on the game field F".

FIG. 6 is a diagram for explaining the game board 10, and shows the game board 10 as viewed from above. As shown in FIG. 6, a plurality of reading devices 20-1 to 20-30 are installed inside the housing 11 of the game board 10. Each of the reading devices 20-1 to 20-30 is an IC tag reader. The IC tag reader is provided with an antenna for transmitting and receiving a signal to and from the IC tag, transmits the signal via radio, and receives the signal returned from the IC tag that has received the signal, thereby IC. It reads the information stored in the tag (IC chip).

The reading devices 20-1 to 20-30 are installed so as to correspond to the zones Z1 to Z30 of the game field F, respectively. For example, the reading device 20-1 corresponds to the zone Z1 and is installed at a position corresponding to the zone Z1. Specifically, the reading device 20-1 is installed below the zone Z1 and is used to read the information stored in the IC tag 73 of the card 60S placed in the zone Z1. The same applies to the readers 20-2 to 20-30. In the following, when it is not necessary to distinguish each of the reading devices 20-1 to 20-30, these are collectively referred to as "reading device 20".

The front surface portion 71 and the back surface portion 72 of the card 60 and the sleeve 70 are formed of a material that does not interfere with the transmission / reception of signals between the IC tag 73 and the reading device 20. Therefore, regardless of whether the card 60S is placed face up or face down in the zone Z, the reading device 20 installed under the zone Z reads the information stored in the IC tag 73 of the card 60S. be able to.

Further, even when a plurality of cards 60S are stacked and placed in one zone Z, the reading device 20 installed under the zone Z stores in each IC tag 73 of the plurality of cards 60S. The information that has been sent can be read.

Further, the reading device 20 installed under the zone Z is installed away from the other zones Z, and can read the information stored in the IC tag 73 of the card 60S placed in the other zones Z. There is no such thing.

The game board 10 and the information processing device 40 are connected to each other via a cable conforming to a predetermined interface standard. Alternatively, the game board 10 and the information processing device 40 can communicate with each other via a communication network. The reading result data regarding the reading result of the reading device 20 is supplied to the information processing device 40 via the cable or the communication network.

The photographing device 30 is a visible light camera, which is a device that converts an optical image obtained through a lens into an electronic image signal by an image sensor and outputs it. The photographing device 30 is fixed above the game board 10 (game field F) and is used for photographing the game field F. The captured image of the photographing device 30 includes at least zones Z1 to Z30 of the game field F.

The photographing device 30 and the information processing device 40 are connected via a cable conforming to a predetermined interface standard. Alternatively, the photographing device 30 and the information processing device 40 can communicate with each other via a communication network. The photographing device 30 photographs the game field F at predetermined time intervals, and the captured image is supplied to the information processing apparatus 40 via the cable or the communication network.

The information processing device 40 is a computer, and includes a control unit 41, a storage unit 42, a communication unit 43, an operation unit 44, a display unit 45, and a voice output unit 46. The control unit 41 includes at least one microprocessor and executes information processing according to a program stored in the storage unit 42.

The audio output unit 46 is for outputting audio, and is, for example, a speaker, headphones, or the like. The operation unit 44, the display unit 45, and the voice output unit 46 may be provided in the information processing device 40 itself, or may be provided as an external device connected to the information processing device 40. For example, the display unit 45 may be a head-mounted display (HMD), a monitor, a television receiver, a projector, or the like connected to the information processing device 40 as an external device.

The information processing device 40 is based on the reading result data of the reading device 20 and the captured image of the photographing device 30, and the type and state of the card 60S placed on the game field F (that is, the state accommodated in the sleeve 70). (Type and state of the card 60 placed on the game field F) is specified. Further, the information processing device 40 causes the display terminal device 50 to display a game field image showing the current status of the game field F based on the specific result. The processing executed by the information processing apparatus 40 will be described later (see FIGS. 10, 12, 13, 18 and the like).

The display terminal device 50 is a device capable of displaying an image. For example, the display terminal device 50 is a device for a spectator who watches a match of a card game. Specifically, the display terminal device 50 is a terminal device (for example, a smartphone, a tablet computer, a laptop computer, a desktop computer, etc.) used by an individual audience, and is controlled as shown in FIG. It is a computer including a unit 51, a storage unit 52, a communication unit 53, an operation unit 54, a display unit 55, and an audio output unit 56. The control unit 51, the storage unit 52, the communication unit 53, the operation unit 54, the display unit 55, and the audio output unit 56 are the control unit 41, the storage unit 42, the communication unit 43, the operation unit 44, the display unit 45, and the audio output unit. It is the same as 46. Although the operation unit 54 and the display unit 55 are shown separately in FIG. 1, the operation unit 54 and the display unit 55 may be integrally formed as a touch panel. The operation unit 54 may be a pointing device such as a mouse, a button (key), a lever (stick), or the like. The operation unit 54 may be for the audience to operate by voice or gesture.

Hereinafter, the display terminal device 50 will be described assuming that it is a terminal device (for example, a smartphone or the like) used by an individual audience, but the display terminal device 50 is not limited to this. For example, the display terminal device 50 may be a display-only device having only a display function. For example, the display terminal device 50 may be a large monitor installed in a venue with a plurality of spectators and viewed by a plurality of spectators.

On the display unit 55 of the display terminal device 50, for example, a game field image showing the current status of the game field F (game board 10) is displayed. The spectator can grasp the current situation of the game field F by looking at the game field image.

FIG. 7 shows an example of the situation of the game field F (game board 10), and FIG. 8 shows an example of the game field image in the case of the situation shown in FIG. 7.

In the situation shown in FIG. 7, the card 60S-1 is placed in the zone Z10 with the back side defense display. Further, the card 60S-2 is placed in the zone Z12 in the face-up attack display. Further, the card bundle 600-1 (first player's deck), 600-2, 600-3 (second player's deck), and 600-4, which are a plurality of cards 60S stacked face down, are zone Z7. , Z1, Z21, Z15 respectively. It is assumed that the card bundle 600-1 contains 50 cards 60S, and the card bundle 600-2 contains 12 cards 60S. Further, it is assumed that the card bundle 600-3 contains 45 cards 60S, and the card bundle 600-4 contains 15 cards 60S.

As shown in FIG. 8, the game field image G shows the current state of the game field F. Zones Z1 to Z30 are drawn on the game field image G. The game field image G shown in FIG. 8 includes parts PA-1, PA-2, PA-3, PA-4, PB-1, and PB-2.

The part PA-1 is an object corresponding to the card bundle 600-1 placed in the zone Z7, and is displayed in association with the zone Z7. The part PA-2 is an object corresponding to the card bundle 600-2 placed in the zone Z1 and is displayed in association with the zone Z1. The part PA-3 is an object corresponding to the card bundle 600-3 placed in the zone Z21, and is displayed in association with the zone Z21. The part PA-4 is an object corresponding to the card bundle 600-4 placed in the zone Z15, and is displayed in association with the zone Z15. The numerical value described in the part PA-1 indicates the number of cards 60S included in the card bundle 600-1. The same applies to parts PA-2 to PA-4.

The part PB-1 is an object corresponding to the card 60S-1 placed in the zone Z10, and is displayed in association with the zone Z10. In the situation shown in FIG. 7, since the card 60S-1 is placed in the zone Z10 in the backside defense display, an image showing the card 60 placed sideways and face down as the part PB-1 (that is, placed sideways). An image showing the back surface 62 of the card 60 is displayed at a position corresponding to the zone Z10. In other words, as the part PB-1, the image corresponding to the type of the card 60 is not displayed, and the image not depending on the type of the card 60 is displayed at the position corresponding to the zone Z10.

The part PB-2 is an object corresponding to the card 60S-2 placed in the zone Z12, and is displayed in association with the zone Z12. In the situation shown in FIG. 7, since the card 60S-2 is placed in the zone Z12 in the face-up attack display, an image showing the card 60 placed vertically and face up as the part PB-2 (that is, vertically). An image showing the surface 61 of the placed card 60) is displayed at a position corresponding to the zone Z12. In other words, as the part PB-2, unlike the part PB-1, an image corresponding to the type of the card 60 is displayed at a position corresponding to the zone Z12.

The part PB-1 is associated with a process for displaying the information of the card 60S-1 placed in the zone Z10. Therefore, when a designated operation for designating the part PB-1 (for example, a tap operation for the part PB-1) is accepted, the information of the card 60S-1 is displayed. FIG. 9 shows an example of the game field image G when the designated operation of the part PB-1 is accepted. When the designated operation of the part PB-1 is accepted, as shown in FIG. 9, an image showing the surface 61 of the card 60S-1 placed in the zone Z10 is displayed as the part PC.

Normally, the spectator cannot grasp the name and performance of the card 60S-1 placed face down, but in the present embodiment, the parts PC as shown in FIG. 9 is displayed according to the designated operation of the parts PB-1. Therefore, the spectator can grasp the name and performance of the card 60S-1 placed face down. Instead of displaying the image showing the surface 61 of the card 60S-1 as the parts PC, a text message showing the name and performance of the card 60S-1 may be displayed as the parts PC.

Similar to the part PB-1, the part PB-2 is associated with a process for displaying the information of the card 60S-2 placed in the zone Z12. Therefore, when the designated operation of the part PB-2 is accepted, the image showing the surface 61 of the card 60S-2 is displayed as the part PC. Since the part PC is larger than the part PB-2, the spectator can easily grasp the name and performance of the card 60S-2 placed in the zone Z12 by referring to the part PC.

The part PA-1 may be associated with a process for displaying a list of cards 60S included in the card bundle 600-1 placed in the zone Z7. Then, the list of the cards 60S included in the card bundle 600-1 may be displayed according to the designated operation of the part PA-1. In this way, the spectator may be able to grasp the list of cards 60S included in the card bundle 600-1 placed in the zone Z7. The same applies to parts PA-2 to PA-4.

Further, in the above, the game field image G displayed on the display unit 55 of the display terminal device 50 changes according to the operation of the spectator performed by the display terminal device 50 (for example, from the state shown in FIG. 8 to FIG. 9). Although it has been described as changing to the indicated state), the game field image G displayed on the display unit 55 of the display terminal device 50 may be changed according to the operation performed by the information processing device 40. .. For example, the parts PC shown in FIG. 9 is displayed in the game field image G in response to a designated operation performed by a representative who performs a live commentary or a live performance of a card game using the operation unit 44 of the information processing device 40. You may do so.

Further, not only the game field image G but also the captured image of the photographing device 30 may be displayed on the display unit 55 of the display terminal device 50. For example, both the game field image G and the captured image of the photographing device 30 may be displayed on the display unit 55. Further, for example, the image displayed on the display unit 55 may be switched between the game field image G and the captured image of the photographing device 30 in response to a predetermined switching instruction.

[1-3. Processing] The processing executed by the system 1 will be described.

[1-3-1] As will be described later, the information processing apparatus 40 executes a specific process for specifying the type and state of the card 60S placed in the game field F based on the reading result of the reading apparatus 20. For this specific process, the card ID of the card 60 and the sleeve 70 accommodating the card 60 need to be associated with each other. Therefore, prior to starting the card game, an association process for associating the card ID of the card 60 with the sleeve 70 accommodating the card 60 is executed.

[1-3-1-1] FIG. 10 is a flow chart showing an example of the association process. For example, the player places one card 60S from his or her deck in a predetermined zone Z (for example, zone Z11, etc.) in the game field F in portrait and face up directions. In this state, the association process shown in FIG. 10 is executed.

As shown in FIG. 10, first, the control unit 41 of the information processing apparatus 40 acquires a captured image of the photographing device 30 (S400). Then, the control unit 41 identifies the card ID of the card 60S shown in the captured image (that is, the card ID of the card 60 placed in the zone Z while being housed in the sleeve 70) from the captured image (S402). ..

For example, the storage unit 42 is generated by executing machine learning based on learning data including a photographed image of the game field F in which the card 60S is placed and a card ID (correct answer data) of the card 60S. A trained model (a model for specifying the card ID of the card 60S shown in the captured image) is stored in advance. Then, in step S402, the control unit 41 uses the trained model to specify the card ID of the card 60S shown in the captured image.

The storage unit 42 may store in advance feature data in which the card ID of the card 60S and the appearance feature information indicating the appearance feature of the card 60S are associated with each other. Then, in step S402, the control unit 41 analyzes the captured image to extract the appearance feature information of the card 60S shown in the captured image, and is most similar to the extracted appearance feature information (or the extracted appearance feature information). The card ID associated with the appearance feature information) may be specified as the card ID of the card 60S shown in the captured image.

After executing step S402, the control unit 41 acquires the tag ID read by the reading device 20 (S404). When the card 60S is placed in the zone Z, the tag ID stored in the IC tag 73 of the card 60S is read by the reading device 20 installed under the zone Z, and the read tag ID is read. It is supplied to the information processing device 40. The control unit 41 acquires the tag ID supplied in this way.

After executing step S404, the control unit 41 registers the association between the card ID specified in step S402 and the tag ID acquired in step S404 in the association data D1 (S406).

FIG. 11 shows an example of the association data D1 stored in the storage unit 42. The association data D1 includes "card ID" and "tag ID" fields. The "card ID" field is a field for registering a card ID, and the "tag ID" field is a field for registering a tag ID.

In step S406, the control unit 41 adds a new record to the association data D1, and the card ID specified in step S402 and the tag ID acquired in step S404 are combined with the "card ID" and "tag" of the added record. Register in the "ID" field.

After the execution of step S406, a completion notification indicating that the association process is completed is output. For example, an image indicating the completion notification may be displayed on the display unit 45, or a voice indicating the completion notification may be output from the voice output unit 46. In response to the completion notification, the player removes the card 60S placed in the zone Z and places the next card 60S from his / her deck in the zone Z vertically and face up. In this state, the association process shown in FIG. 10 is executed again.

By executing the association process shown in FIG. 10 for each card 60S included in the deck of the first player, information on all the cards 60S included in the deck of the first player is registered in the association data D1. Further, for each card 60S included in the deck of the second player, the information of all the cards 60S included in the deck of the second player is registered in the association data D1 by executing the association process shown in FIG. To.

[1-3-1-2] The association process is not limited to the process shown in FIG. FIG. 12 is a flow chart showing another example of the association processing. Instead of the association process shown in FIG. 10, the association process shown in FIG. 12 may be executed.

The association process shown in FIG. 12 is premised on the fact that an IC tag writer for writing information to the IC tag 73 is installed under the zone Z. Hereinafter, the reader 20 installed under the zone Z will be described as an IC tag reader / writer having both functions of an IC tag reader and an IC tag writer.

As shown in FIG. 12, first, the control unit 41 of the information processing apparatus 40 acquires a captured image of the photographing device 30 (S420). Then, the control unit 41 identifies the card ID of the card 60S shown in the captured image from the captured image (S422). The processing of steps S420 and S422 is the same as that of steps S400 and S402 of FIG.

After executing step S422, the control unit 41 writes the card ID specified in step S422 to the IC tag 73 of the card 60S placed in the zone Z (S424). That is, the control unit 41 sends the writing instruction of the card ID specified in step S422 to the reading device 20 placed under the zone Z. Then, in response to the writing instruction, the reading device 20 writes the card ID specified in step S422 to the IC tag 73 of the card 60S placed in the zone Z.

By executing the association process shown in FIG. 12 for each card 60S included in the deck of the first player, the IC tag 73 of each card 60S included in the deck of the first player has the card ID of the card 60S. Is remembered. Further, with respect to each card 60S included in the deck of the second player, the association process shown in FIG. 12 is executed, so that the card 60S is attached to the IC tag 73 of each card 60S included in the deck of the second player. Card ID is stored. In this case, the association between the card ID of the card 60 and the sleeve 70 accommodating the card 60 is not stored as the association data D1 as shown in FIG. 11, but is stored in the IC tag 73 of each sleeve 70. It will be remembered.

[1-3-1-3] Here, it has been described that the association process is executed using the system 1, but it is not essential to execute the association process using the system 1. For example, an association system including a photographing device and an IC tag reader (IC tag reader / writer) may be prepared separately from the system 1 and the association process may be executed using the system. Further, it is sufficient that the association is completed at the time when the card game is started, and the timing of executing the association does not have to be immediately before the start of the card game.

[1-3-2] During the play of the card game, the information processing apparatus 40 executes a specific process for specifying the type and state of the card 60S placed in the game field F. FIG. 13 is a flow chart showing an example of specific processing. The specific process shown in FIG. 13 is based on the premise that the association data D1 shown in FIG. 11 is stored in the storage unit 42.

As shown in FIG. 13, first, the control unit 41 of the information processing apparatus 40 acquires a captured image of the photographing device 30 (S430). Then, the control unit 41 identifies the position and orientation of the card 60S placed in the game field F from the captured image (S432).

In the present embodiment, for example, as shown in FIG. 14, 35 regions A1 to A35 formed by dividing the captured image I into vertical 5 × horizontal 7 are set. Of these, the areas A1 to A30 are set so as to correspond to the zones Z1 to Z30 of the game field F. In the following, when it is not necessary to specify each of the regions A1 to A35, they are collectively referred to as “region A”.

In step S432, the control unit 41 specifies whether or not the card 60S is captured in each area A of the captured image, and the orientation (vertical / horizontal orientation or front / back orientation) of the captured card 60S. Here, "specifying the vertical and horizontal orientation of the card 60S" means specifying whether the card 60S is placed in the vertical or landscape orientation, and "specifying the front and back orientation of the card 60S". Is to specify whether the card 60S is placed face up or face down.

For example, the storage unit 42 is a machine based on learning data including a photographed image of the game field F in which the card 60S is placed and correct answer data indicating the area A in which the card 60S is placed and the orientation of the card 60S. The trained model generated by executing the learning (a model for specifying whether or not the card 60S is shown in each area A of the captured image and the orientation of the shown card 60S) is stored in advance. .. Then, in step S432, the control unit 41 uses the trained model to specify whether or not the card 60S is reflected in each area A of the captured image and the orientation of the captured card 60S.

In the storage unit 42, for each individual card 60S, data in which the orientation of the card 60S is associated with the appearance feature information indicating the appearance characteristics of the card 60S when placed in that orientation is stored in advance in the storage unit 42. You may leave it. Then, in step S422, the control unit 41 analyzes the captured image to determine whether or not the appearance feature information of the card 60S is extracted from the region A of the captured image, so that the card 60S appears in the region A. It may be possible to specify whether or not the card is used, or to specify the orientation of the card 60S shown in the area A from the extracted appearance feature information.

The specific result in step S432 is registered in the first specific result data D2. FIG. 15 shows an example of the first specific result data D2. As shown in FIG. 15, the first specific result data D2 includes "area ID", "vertical and horizontal flags", and "front and back flags" fields.

The "region ID" field indicates a region ID that is information that uniquely identifies each region A set in the captured image. The "vertical / horizontal flag" field is a field for registering a vertical / horizontal flag indicating a specific result of the vertical / horizontal orientation of the card 60S shown in the area A. For example, if the card 60S is specified to be portrait, the value "0" is registered in the "vertical / horizontal flag" field, and if the card 60S is specified to be landscape, the value "1" is Registered in the "Vertical / Horizontal Flag" field. Further, the "front and back flag" field is a field for registering the front and back flags indicating the specific result of the front and back orientation of the card 60S shown in the area A. For example, if the card 60S is specified to be face up, the value "0" is registered in the "front and back flag" field, and if the card 60S is specified to be face down, the value "1" is Registered in the "Front and back flags" field. When the card 60S is not shown in the area A, the "vertical and horizontal flags" and "front and back flags" fields are set to blank (Null). In the following, among the records of the first specific result data D2, the record in which "An" (n: natural number) is registered in the "area ID" field is described as "the record of the area ID" An "". do.

For example, in the case of the situation shown in FIG. 7, in step S432, (a) the card 60S is shown in each of the areas A1, A7, A10, A12, A15, and A21, and (b) is shown in the area A10. The orientation of the card 60S is sideways and face down, (c) the orientation of the card 60S shown in the area A12 is portrait and face up, and (d) the areas A1, A7, A15, A21. It is specified from the captured image that the card 60S in the picture is oriented vertically and face down, and the specific result is registered in the first specific result data D2.

After the execution of step S432, the control unit 41 acquires the reading result data of each reading device 20 supplied from the game board 10 (S434), and reads the position and the card ID of the card 60S placed in the game field F. Specify from the data (S436).

For example, in the case shown in FIG. 7, the reading device 20-10 installed under the zone Z10 reads the tag ID stored in the IC tag 73 of the card 60S-1 placed in the zone Z10. , The tag ID is supplied to the information processing apparatus 40 as reading result data. Then, the control unit 41 refers to the association data D1 and identifies the card ID associated with the tag ID read by the reading device 20-10. In this way, the card ID of the card 60S-1 placed in the zone Z10 is specified.

Similarly, the reading device 20-12 installed under the zone Z12 reads the tag ID stored in the IC tag 73 of the card 60S-2 placed in the zone Z12, and reads the tag ID as a result of reading. It is supplied to the information processing apparatus 40 as data. Then, the control unit 41 refers to the association data D1 and identifies the card ID associated with the tag ID read by the reading device 20-12. In this way, the card ID of the card 60S-2 placed in the zone Z12 is specified.

Further, the reading device 20-7 installed under the zone Z7 reads the tag ID stored in the IC tag 73 of each card 60S included in the card bundle 600-1 placed in the zone Z7. Those tag IDs are supplied to the information processing apparatus 40 as reading result data. Then, the control unit 41 refers to the association data D1 and identifies the card ID associated with each tag ID read by the reading device 20-7. In this way, the card ID of each card 60S included in the card bundle 600-1 placed in the zone Z7 is specified. Similar to zone Z7, the card ID is specified for zones Z1, Z15, and Z21.

The specific result in step S436 is registered in the second specific result data D3. FIG. 16 shows an example of the second specific result data D3. As shown in FIG. 16, the second specific result data D3 includes the “reader ID” and “card ID” fields.

The "reading device ID" field indicates a reading device ID that is information that uniquely identifies each reading device 20. In FIG. 16, the reader ID of the reader 20-n (n: natural number) is described as "Rn". The "card ID" field is a field for registering the card ID specified from the reading result data of the reading device 20. For the reading device 20 that did not read the tag ID stored in the IC tag 73, the "card ID" field is set to blank (Null). In the following, among the records of the second specific result data D3, the record in which "Rn" (n: natural number) is registered in the "reading device ID" field is referred to as "record of reading device ID" Rn "". It is described as.

For example, in the case shown in FIG. 7, the card ID (that is, the card ID specified from the tag ID read by the reader 20-10) is set in the "card ID" field of the record of the reader ID "R10". The card ID of the card 60S-1 placed in the zone Z10) is registered. Further, for the "card ID" field of the record of the reading device ID "R12", the card ID specified from the tag ID read by the reading device 20-12 (that is, the card 60S-2 placed in the zone Z12). Card ID) is registered.

Further, for the "card ID" field of the record of the reader ID "R7", a list of card IDs identified from the plurality of tag IDs read by the reader 20-7 (ie, zone Z7) is placed. A list of card IDs of the card 60S included in the card bundle 600-1) is registered. The same applies to the "card ID" field of the records of the reader IDs "R1", "R15", and "R21". The "card ID" field of records other than the records of the reader IDs "R1", "R7", "R10", "R12", "R15", and "R21" is set to blank (Null).

Although the description has been made on the premise that the association data D1 shown in FIG. 11 is registered in the storage unit 42 by the association processing shown in FIG. 10, the card 60S is described by the association processing shown in FIG. When the ID is registered in the IC tag 73 of the card 60S, the process described below is executed in step S436.

For example, in the case shown in FIG. 7, the reading device 20-10 installed under the zone Z10 reads the card ID stored in the IC tag 73 of the card 60S placed in the zone Z10, and the card ID is read. The card ID is supplied to the information processing apparatus 40 as reading result data. Then, the control unit 41 registers the card ID read by the reading device 20-10 in the "card ID" field of the record of the reading device ID "R10". The same applies to zone Z12.

Further, the reading device 20-7 installed under the zone Z7 reads the card ID stored in the IC tag 73 of each card 60S included in the card bundle 600-1 placed in the zone Z7. Those card IDs are supplied to the information processing apparatus 40 as reading result data. Then, the control unit 41 registers the plurality of card IDs read by the reading device 20-7 in the "card ID" field of the record of the reading device ID "R7". The same applies to zones Z1, Z15, and Z21.

After executing step S436, the control unit 41 generates game field status data D4 based on the first specific result data D2 and the second specific result data D3 (S438).

FIG. 17 shows an example of the game field situation data D4. The game field status data D4 is data indicating the current status of the game field F. More specifically, the game field status data D4 is the current status of each zone Z in the game field F (whether or not the card 60S is placed in the zone Z, and the card 60S placed in the zone Z. It is data indicating the type and arrangement format).

As shown in FIG. 17, the game field status data D4 includes "zone ID", "card ID", "vertical and horizontal flags", and "front and back flags" fields. The "zone ID" field indicates a zone ID that is information that uniquely identifies each zone Z in the game field F. The "card ID" field is the same as the "card ID" field of the second specific result data D3. The "vertical and horizontal flags" and "front and back flags" fields are the same as the "vertical and horizontal flags" and "front and back flags" fields of the first specific result data D2. In the following, among the records of the game field status data D4, the record in which "Zn" (n: natural number) is registered in the "zone ID" field is described as "the record of the zone ID" Zn "". ..

In step S438, the control unit 41 collates the "area ID" field of the first specific result data D2 with the "reader ID" field of the second specific result data D3, and collates the first specific result data D2 with the second specific result data D2. The game field status data D4 is generated by synthesizing the specific result data D3.

For example, the record of the reading device ID "R1" in the record of the second specific result data D3 and the record of the area ID "A1" in the record of the first specific result data D2 both correspond to the zone Z1. Records relating to the reader 20-1 or region A1 to be read, and these records correspond to each other. Therefore, the control unit 41 has the card ID registered in the "card ID" field of the record of the reading device ID "R1" among the records of the second specific result data D3, and the record of the first specific result data D2. Of these, the combination of the vertical / horizontal flag and the front / back flag registered in the "vertical / horizontal flag" and "front / back flag" fields of the record of the area ID "A1" which is the record corresponding to the reader ID "R1" is used in the zone Z1. It is registered in the game field status data D4 as information indicating the current status of. That is, the control unit 41 registers the combination in the "card ID", "vertical and horizontal flags", and "front and back flags" fields of the record of the zone ID "Z1" among the records of the game field status data D4. The same applies to zones Z2 to Z30.

[1-3-3] During the play of the card game, a display control process for displaying the game field image G on the display unit 55 of the display terminal device 50 is executed. For example, the storage unit 42 stores card data in which the card ID, the information of the card 60, and the image (surface 61) are associated with each other, and the game field image G includes the card data and the game field status data D4. Is displayed based on. FIG. 18 shows an example of display control processing.

As shown in FIG. 18, the control unit 41 of the information processing device 40 transmits data related to the game field image G to the display terminal device 50 (S440) via the communication unit 43, and the display terminal device 50 sends the communication unit 53. The data is received via (S500). Then, the control unit 51 of the display terminal device 50 causes the display unit 55 to display the game field image G based on the data (S502).

Here, the "data related to the game field image G" is data necessary for displaying the game field image G on the display terminal device 50 (display unit 55). For example, the card data and the game field status data D4 correspond to an example of "data related to the game field image G". The card data may be stored in advance in the storage unit 52 of the display terminal device 50, in which case it is not necessary to transmit the card data to the display terminal device 50. The game field image G itself may be transmitted to the display terminal device 50 as "data related to the game field image G".

Further, when the game field image G is generated, whether or not the front and back flags of the card 60S registered in the game field status data D4 are "1" (in other words, the orientation of the card 60S specified in step S432). Is face down) is determined. Then, according to the determination result, the parts showing the card 60S are displayed in the game field image G.

For example, when the front / back flag of the card 60S is not "1" (in other words, the direction of the card 60S specified in step S432 is not face down but face up), as a part indicating the card 60S, for example, FIG. An image showing the surface 61 of the card 60S, such as the part PB-2 shown in 7, is displayed in the game field image G. That is, as a part indicating the card 60S, an image corresponding to the card ID of the card 60S registered in the game field status data D4 (in other words, an image corresponding to the type of the card 60S specified in step S432) is displayed. Will be done.

On the other hand, when the front / back flag of the card 60S is "1" (that is, the direction of the card 60S specified in step S432 is face down), as a part indicating the card 60S, for example, it is shown in FIG. An image showing the back surface 62 of the card 60S, such as the part PB-1, is displayed in the game field image G. That is, as a part indicating the card 60S, an image that does not depend on the card ID of the card 60S registered in the game field status data D4 (in other words, an image that does not depend on the type of the card 60S specified in step S432) is displayed. Will be done.

The game field image G may be displayed on the display unit 45 of the information processing device 40. That is, the control unit 41 of the information processing apparatus 40 may display the game field image G on the display unit 45 based on the game field status data D4.

[1-3-4] FIG. 19 shows an example of a process repeatedly executed by the display terminal device 50 while the game field image G is displayed.

As shown in FIG. 19, the control unit 51 of the display terminal device 50 determines whether or not the card designation operation has been accepted (S510). The "card designation operation" is an operation for designating the card 60S displayed on the game field image G. For example, in the case of the game field image G shown in FIG. 8, the designated operation of the parts PB-1 or PB-2 (for example, the tap operation for the parts PB-1 or PB-2) corresponds to the “card designation operation”.

When it is determined that the card designation operation has been accepted (S510: Yes), the control unit 51 displays the card image of the designated card 60S (S512). For example, the parts PC shown in FIG. 9 corresponds to a "card image". For example, when the game field image G shown in FIG. 8 is displayed on the display unit 55 and the designated operation of the part PB-1 corresponding to the card 60S-1 placed in the zone Z10 is performed, control is performed. The unit 51 displays a part PC showing the surface 61 of the card 60S-1 placed in the zone Z10.

Although omitted in FIG. 19, when a predetermined erasing instruction operation (for example, a designated operation for designating a part PC) is performed while the part PC is displayed, the control unit 51 erases the part PC.

When the display terminal device 50 accepts the card designation operation, the display terminal device 50 transmits a notification to the effect that the card designation operation has been accepted, and the control unit 41 of the information processing device 40 transmits FIG. By generating the game field image G as shown in the above and returning it to the display terminal device 50, the game field image G may be displayed on the display terminal device 50.

When the game field image G is displayed on the display unit 45 of the information processing device 40, the process shown in FIG. 19 is executed by the control unit 41 of the information processing device 40.

[1-4. Effect] According to the first embodiment described above, not only the captured image of the photographing device 30 for photographing the game field F, but also the reading result of the reading device 20 for reading the information stored in the IC tag 73 of the card 60S. It can be used to specify the type and state (position, orientation, etc.) of the card 60S placed on the game field F. According to the first embodiment, items that cannot be specified (or are difficult to specify) from the captured image of the photographing device 30 can be specified based on the reading result of the reading device 20.

For example, even when the card 60S is placed face down on the game field F (that is, the card 60S is placed in a state where the surface 61 is not reflected in the captured image of the photographing device 30), the reading device is used. Based on the reading result of 20, the type of the card 60S can be specified, and the information (name, performance, etc.) written on the surface 61 of the card 60S can be specified. Further, for example, even if hologram processing or the like is applied to the card 60S, the type of the card 60S can be specified based on the reading result of the reading device 20, and the information (name and performance) written on the surface 61 of the card 60S can be specified. Etc.) can be specified. Further, for example, even when a plurality of cards 60S are stacked and placed, the type of the plurality of cards 60S can be specified based on the reading result of the reading device 20.

Further, in the first embodiment, the specific result (first specific result) from the captured image of the photographing device 30 includes the specific result regarding the position and orientation of the card 60S, and the specific result from the reading result of the reading device 20 (first specific result). Since the second specific result) includes the specific result regarding the position and type of the card 60S, the specific result (position specific result) regarding the position of the card 60S is included in both the first specific result and the second specific result. .. Therefore, even when a plurality of cards 60S are placed in the game field F, the same card 60S is obtained by collating the position specifying results included in both the first specific result and the second specific result. The combination of the first specific result and the second specific result regarding the above can be specified. That is, even when a plurality of cards 60S are placed in the game field F, the combination of type, position, and orientation can be specified for each individual card 60S.

Further, in the first embodiment, since the IC tag 73 is provided in the sleeve 70, even when the card 60 itself does not have the IC tag, the card 60 can be used by accommodating the card 60 in the sleeve 70. It becomes possible to specify the type and state of the above from the reading result of the reading device 20.

That is, since the card 60 itself does not need to have an IC tag, for example, an existing card 60 that does not have an IC tag can be used.

Further, when the card 60 itself is provided with an IC tag, if the IC tag of the card 60 fails, the card 60 cannot be used, and the player may feel dissatisfied. Some of the cards 60 are highly rare, and if such a highly rare card 60 becomes unusable due to a failure of the IC tag, the player may feel great dissatisfaction. In this respect, when the sleeve 70 includes the IC tag 73, even if the IC tag 73 fails, the card 60 can be continued to be used by replacing the sleeve 70.

Further, in the first embodiment, since the IC tag 73 is provided on the back surface portion 72 of the sleeve 70, it is possible to prevent the front surface 61 of the card 60 housed in the sleeve 70 from being hidden by the IC tag 73 and becoming difficult to see. ..

Further, in the first embodiment, since the appearance of the back surface portion 72 of the sleeve 70 is the same as that of all the sleeves 70, it is possible to ensure that the individual sleeves 70 cannot be distinguished from the appearance of the back surface portion 72.

Further, in the first embodiment, since the game field image G is displayed on the display terminal device 50, it becomes easy for the audience (the person who sees the display terminal device 50) to grasp the current situation of the game field F.

Further, in the first embodiment, even when the card 60S is placed face down on the game field F (that is, when the card 60S is placed with the surface 61 invisible), the surface of the card 60S is placed. Since the part PC showing 61 is displayed on the game field image G, the information (name and performance) written on the surface 61 of the card 60S placed face down, which the audience cannot normally know. Etc.) can provide a new interest of being able to know. As a result, it is possible to improve the interest when viewing the card game as a spectator.

In the first embodiment, when a designated operation for designating the card 60S placed face down (for example, a designated operation for designating the part PB-1 in FIG. 8) is accepted, a part showing the surface 61 of the card 60S. Since the PC is displayed, for example, the information (name, performance, etc.) of the card 60S placed face down should not be known in principle, and the above designation operation is performed only when the audience desires. By doing so, it is possible to be able to know.

[1-5. Modification example] The modification of the first embodiment will be described.

[1-5-1] In the embodiment described above, the sleeve 70 includes the IC tag 73, but the sleeve 70 does not include the IC tag 73, but the object and the card 60 having the IC tag 73. May be accommodated in the sleeve 70.

For example, as shown in FIG. 20, the object 80 housed in the sleeve 70 together with the card 60 may include the IC tag 73. The object 80 is formed of a material that does not interfere with the transmission and reception of signals between the IC tag 73 and the reader 20. For example, the object 80 is a sheet-like object having a similar shape to the card 60. In the example shown in FIG. 20, the shape and size of the object 80 are the same as (or substantially the same as) the card 60, but the shape and size of the object 80 may be different from the card 60. The IC tag 73 may be attached to either surface of the object 80.

The card 60 is housed in the sleeve 70 so that the front surface 61 and the front surface 71 of the sleeve 70 face each other, and the object 80 is housed between the back surface 62 of the card 60 and the back surface 72 of the sleeve 70. .. When used in a card game, both the card 60 and the object 80 are housed in a sleeve 70. It is sufficient that both the card 60 and the object 80 are housed in the sleeve 70 when used in a card game, and when the card 60 is housed in the sleeve 70, the card 60 and the object 80 are housed in the sleeve 70. It is not necessary to put them all together in the sleeve 70 at the same time. The object 80 may be housed in the sleeve 70 after the card 60 is housed in the sleeve 70, or the card 60 may be housed in the sleeve 70 after the object 80 is housed in the sleeve 70. The card 60 and the object 80 may be collectively housed in the sleeve 70 at the same time.

Even if the object 80 as described above is housed in the sleeve 70 together with the card 60, items that cannot be specified (or are difficult to identify) from the captured image of the photographing device 30 are the same as in the case where the IC tag 73 is attached to the sleeve 70. It becomes possible to identify from the reading result of the reading device 20. Further, even when the card 60 itself does not have an IC tag, the type and state of the card 60 can be specified from the reading result of the reading device 20 by accommodating the card 60 together with the object 80 in the sleeve 70. It will be possible.

[1-5-2] The card 60 itself (for example, the back surface 62) may include the IC tag 73. Even in this way, items that cannot be specified (or are difficult to specify) from the captured image of the photographing device 30 can be specified based on the reading result of the reading device 20.

[1-5-3] Before starting the card game, when the player's deck is placed in the zone Z7 or Z21 as a deck, the specific process shown in FIG. 13 is executed, and based on the game field status data D4, the specific process is executed. It may be determined whether or not the player's deck placed in the zone Z7 or Z21 complies with the rules. Then, if the deck does not follow the rules, a warning notification may be output.

In the above [1-5-4], the information stored in the IC tag 73 of the card 60S placed in the zone Z is not read by the reading device 20 installed under the other zone Z. As described above, when the information stored in the IC tag 73 of the card 60S is read by the plurality of reading devices 20, the strength of the signal received from the IC tag 73 among the plurality of reading devices 20 is used. The strongest reading device 20 may be regarded as the reading device 20 that has read the information stored in the IC tag 73. For example, when the information stored in the IC tag 73 of the card 60S is read by the reading devices 20-9 and 20-10, the reading device 20-10 has a stronger reception signal strength than the reading device 20-9. For example, it may be specified that the card 60S is placed in the zone Z10.

[1-5-5] In the embodiment described above, the readers 20-1 to 20-30 are installed at a plurality of positions corresponding to the zones Z1 to Z30, but instead of doing so, A reading device 20 having antennas arranged in a grid pattern may be installed inside the housing 11 of the game board 10.

For example, as shown in FIG. 21, as an antenna of the reading device 20, a plurality of first antennas 21 extending in the first direction (for example, the vertical direction) are arranged at predetermined intervals, and a plurality of antennas extending in the second direction (for example, the horizontal direction) are arranged. The second antennas 22 may be arranged at predetermined intervals. In this case, the combination of the first antenna 21 and the second antenna 22 that received the signal from the IC tag 73 (in other words, the combination of the first antenna 21 and the second antenna 22 having the strongest signal strength received from the IC tag 73). ), The position where the card 60S is placed can be specified. For example, the card 60S is placed at the intersection of the first antenna 21 and the second antenna 22 (in other words, the first antenna 21 and the second antenna 22 having the strongest received signal strength) that have received the signal from the IC tag 73. It can be specified as a position.

[1-5-6] Although the sleeve 70 has been described as being provided (sold or the like) separately from the card 60, the sleeve 70 may be provided together with the card 60. In this case, the sleeve 70 may be provided with the card ID stored in the IC tag 73 (IC chip).

[1-5-7] The card game played by the player is not limited to the card game described above. For example, the position and number of zones Z set in the game field F are not limited to the example shown in FIG. Further, depending on the card game, the area where the card 60 is placed, such as zones Z1 to Z30, is not limited, and the player may be able to place the card 60 at an arbitrary position in the game field F. According to the modification shown in FIG. 21, even when the player places the card 60 at an arbitrary position in the game field F, the position where the card 60 is placed can be specified.

[1-5-8] The game played by the player may be a game played using a game medium other than the card 60. For example, the game played by the player may be a game played using a game medium such as a figure, a piece, or a tile, or a game medium having a shape like a go stone.

[1-6. Functional elements] The functional elements included in the system 1 will be described. FIG. 22 is a functional block diagram for explaining the functional elements included in the system 1.

[1-6-1] The system 1 is a system related to a game played by using an object 100 placed on an object surface, and includes functional elements related to the game.

The "game played using the object 100 placed on the target surface" is, for example, a game that progresses by placing the object 100 on the target surface, and specifically, the game is placed on the target surface. This is a game in which the type or state (position or orientation, etc.) of the object 100 that has been struck affects the progress or result (win / loss, success / failure, score, etc.) of the game. For example, a game in which two players play against each other by placing a game medium on the game field corresponds to an example of the above-mentioned "game". For example, as an example of "a game played by using an object 100 placed on a target surface", a card game in which two players play against each other by placing a card 60 on the game field F as described above is used as an example. Equivalent to.

The above-mentioned "game" is not limited to a game in which two players play against each other, and may be a game in which three or more players play against each other, or a game in which one player plays against each other. Further, the above-mentioned "game" may be a game in which two or more players cooperate to aim at achieving the purpose.

The "object surface" is a surface provided in the real world, and is a surface on which the object 100 is placed. For example, the "target surface" is called a "game field" or a "play field" or the like. The "object surface" may be a flat surface, or may be a surface having irregularities or a curved surface as long as the object 100 can be placed.

The object 100 is a real object to be placed on the target surface, and is an object to be used in the game. For example, the object 100 is an object in which a game medium is housed in an accommodating body. That is, the object 100 is a game medium housed in the housing. In other words, the object 100 is an container in which the game medium is housed. Further, for example, the object 100 may be the game medium itself (game medium alone).

The "game medium" is, for example, a card, a figure, a piece, a tile, or the like. The "game medium" may be an object having a shape like a go stone.

A "containment body" is an object capable of accommodating an individual game medium. In other words, the "containment body" is an insertable body into which a game medium can be inserted. The "containment body" is used to protect the game medium. At least a part of the "containment body" is transparently configured, and at least an appearance feature portion (a portion having an appearance feature distinguishable from other game media) of the housed game medium can be visually recognized from outside the containment body. It is configured in. For example, a "container" is a bag-shaped object and is called a "sleeve" or the like.

For example, the object 100 includes a description surface on which information is written. The “statement surface” is a surface on which information about the object 100 is written. For example, information corresponding to the type of the object 100 is written on the description surface. In other words, information specific to the type of the object 100 is written on the description surface. For example, a text or a pattern peculiar to the type of the object 100 is written on the writing surface. The information written on the description surface can also be said to be information that can be specified from the types of the object 100.

For example, when the object 100 is a game medium housed in an accommodation body (or a game medium alone), information about the game medium housed in the housing body is written on the description surface. For example, when the object 100 is a card housed in a sleeve (or a single card), the name, attribute, content of the influence on the progress or result of the game, the design, etc. are written on the description surface. Will be done.

Further, the "description surface" is a surface on which the type of the object 100 can be specified from the photographed image if this surface is reflected in the photographed image. That is, the "description surface" is a surface on which the content that can specify the type of the object 100 is described.

The information described in the "statement surface" is not limited to the information related to the object 100, but may be information related to the game.

Further, for example, the object 100 includes a first surface portion and a second surface portion different from the first surface portion. For example, the second surface portion is a surface portion on the opposite side of the first surface portion. The angle between the normal direction of the outer surface of the first surface portion and the normal direction of the outer surface of the second surface portion is 180 degrees or approximately 180 degrees. When the object 100 is placed on the target surface so that the outer surface of the first surface portion and the target surface are in contact with each other, the outer surface of the second surface portion faces upward, and the outer surface of the second surface portion When the object 100 is placed on the target surface so that the object surface is in contact with the target surface, the first surface portion and the second surface portion have a relationship in which the outer surface of the first surface portion faces upward. Have.

When the object 100 is an object in which the game medium is housed in the housing, the housing includes the first surface portion and the second surface portion, and the game medium includes the description surface. When the game medium is not housed in the accommodating body, the inner surface of the first surface portion and the inner surface of the second surface portion face each other, and when the game medium is housed in the accommodating body, the first surface portion (inside the first surface portion). Side surface) and the description surface of the game object face each other. For example, all or a part of the first surface portion is formed by using a transparent material (transparent film or the like), and the first surface portion is a first surface portion of a game object housed in a housing from outside the housing. It is configured to be visible through the face portion. When the game medium is a card, when the card is housed in the housing, the inner surface of the first surface portion and the first surface (for example, the surface / description surface) of the card face each other, and the inner surface of the second surface portion and the card The second surface (for example, the back surface) of the above faces each other.

As shown in FIG. 22, the object 100 includes a holding portion 101. The holding unit 101 is for holding specific information as described below. For example, the holding portion 101 is provided on a surface different from the above-mentioned description surface. That is, the object 100 includes the above-mentioned description surface and a holding surface which is a surface provided with the holding portion 101.

For example, the specific information is information for specifying the type or state of the object 100 placed on the object surface. That is, the specific information is information that is the basis for specifying at least one of the type and state of the object 100 placed on the object surface. In other words, the specific information includes at least one of the information that is the basis for specifying the type of the object 100 and the information that is the basis for specifying the state of the object 100. The "information that is the basis for specifying the type of the object 100" may be information indicating the type of the object 100 itself (in other words, information that identifies the type of the object 100). Further, the "information that is the basis for specifying the state of the object 100" may be information indicating the state of the object 100 itself.

When the object 100 is a game medium in which the game medium is housed (or a game medium alone), the specific information is the game medium (or the target surface) placed on the target surface in a state of being housed in the container. Information for identifying the type or state of the game medium (single unit) placed above. That is, the specific information includes information that is the basis for specifying the type of the game medium (or the game medium alone) housed in the container and the state of the game medium (or the game medium alone) housed in the container. Includes at least one of the underlying information to identify.

There is data in which the accommodation ID, which is the identification information that uniquely identifies the accommodation, and the game medium ID, which is the identification information that uniquely identifies the type of the game medium accommodated in the accommodation, are associated with each other. When the type of the game medium housed in the containment can be specified based on the ID, the containment body ID is an example of "information basic for identifying the type of the game medium housed in the containment body". Corresponds to. The identification information that uniquely identifies the holding unit 101 can be used as the housing ID. For example, when the holding unit 101 is an IC tag, a tag ID that is identification information that uniquely identifies each IC tag can be used as the housing ID.

In addition, information indicating the type of the game medium housed in the container itself (in other words, information identifying the type of the game medium) is also "information that is the basis for identifying the type of the game medium housed in the container". Can correspond to an example. Specifically, the game medium ID, which is identification information that uniquely identifies the type of the game medium, can also correspond to an example of "information that is the basis for specifying the type of the game medium housed in the container".

Further, for example, the specific information is information for specifying the information written on the description surface of the object 100 placed on the object surface. That is, the specific information is information that is the basis for specifying the information written on the description surface of the object 100 placed on the object surface. For example, if the information written on the description surface is information related to the type of the object 100, and if the type of the object 100 is specified, the information written on the description surface can be specified, the type of the object is specified. The information that is the basis for identification corresponds to "the information that is the basis for specifying the information written on the description surface of the object 100".

In the above-mentioned card game, the game field F (in other words, the mat 12) corresponds to an example of the “target surface”. Further, the card 60 corresponds to an example of a "game medium", and the sleeve 70 corresponds to an example of a "container". The card 60S, in which the card 60 is housed in the sleeve provided with the IC tag 73, corresponds to an example of the object 100. Further, the front surface portion 71 and the back surface portion 72 of the sleeve 70 correspond to an example of the “first surface portion” and the “second surface portion”, respectively. Further, the front surface 61 of the card 60S corresponds to an example of the "statement surface", and the inner surface of the back surface portion 72 of the sleeve 70 corresponds to an example of the "holding surface".

Further, the IC tag 73 of the card 60S corresponds to an example of the holding unit 101. The tag ID corresponds to an example of "specific information held in the holding unit 101" (information that is the basis for specifying the type of the game medium housed in the housing). When the association process shown in FIG. 12 is executed, the card ID written in the IC tag 73 is "specific information held in the holding unit 101" (the type of the game medium housed in the housing). It corresponds to an example of (information that is the basis for identification).

In the case of the modification shown in FIG. 20, the card 60S in which the object 80 provided with the IC tag 73 and the card 60 are housed in the sleeve 70 corresponds to an example of the object 100, and is provided in the object 80. The attached IC tag 73 corresponds to an example of the holding portion 101. Further, in the case of the modification in which the card 60 itself includes the IC tag 73, the card 60 alone corresponds to an example of the object 100, and the IC tag 73 provided in the card 60 corresponds to an example of the holding portion 101.

[1-6-2] The system 1 displays a functional element for specifying the type and state of the object 100 placed on the target surface and a display regarding the object 100 placed on the target surface 170. As functional elements for displaying the image, a photographing unit 110, a captured image acquisition unit 120, a reading unit 130, a reading result acquisition unit 140, a specific unit 150, and a display control unit 160 are included.

[1-6-3] The photographing unit 110 photographs the target surface on which the object 100 is placed. For example, the photographing unit 110 photographs the target surface from above the target surface. The photographing unit 110 may be capable of photographing the entire target surface, or may be capable of photographing only the area of the target surface on which the object 100 may be placed. In the present embodiment, the photographing device 30 corresponds to the photographing unit 110.

[1-6-4] The reading unit 130 reads the information held by the holding unit 101 of the object 100 placed on the object surface.

The object 100 includes a description surface on which information is written and a holding surface provided with a holding unit 101, and the reading unit 130 has an object surface such that the description surface and the target surface face each other. It is possible to read the information held in the holding portion 101 of the holding surface of the object placed on the top.

For example, the holding unit 101 is an IC tag, and the reading unit 130 reads the information stored in the IC tag. That is, the reading unit 130 includes one or a plurality of IC tag readers. For example, the reading unit 130 includes a plurality of IC tag readers installed at a plurality of positions corresponding to a plurality of positions on the target surface. Further, for example, the reading unit 130 includes an IC tag reader provided with an antenna arranged so as to pass through a plurality of positions on the target surface. In other words, the reading unit 130 is an antenna that receives a signal transmitted from the IC tag, and includes a plurality of antennas installed so as to correspond to a plurality of positions on the target surface, and the object 100 includes a plurality of antennas. Read the information stored in the provided IC tag. In the present embodiment, the reading devices 20-1 to 20-30 installed so as to correspond to the plurality of zones Z1 to Z30 of the game field F correspond to the reading unit 130. In the case of the modification shown in FIG. 21, the antennas (first antenna 21 and second antenna 22) arranged so as to pass through the plurality of positions of the game field F and the corresponding plurality of corresponding positions. The reading device 20 provided with the above corresponds to the reading unit 130.

In the case of the above-mentioned card game example, the IC tag 73 of the sleeve 70 corresponds to an example of the holding portion 101, the surface 61 of the card 60 housed in the sleeve 70 corresponds to an example of the “statement surface”, and the sleeve 70 corresponds to the sleeve 70. The inner surface of the back surface portion 72 corresponds to an example of the “holding surface”.

In the case of the above-mentioned card game example, the reading unit 130 reads a tag ID (an example of information for identifying the holding unit 101) stored in the IC tag 73 of the card 60S placed in the game field F.

When the association process shown in FIG. 12 is executed, the card ID of the card 60S (an example of information for identifying the type of the object 100) is stored in the IC tag 73 of the card 60S, so that the card 60S is read. The unit 130 reads the card ID stored in the IC tag 73 of the card 60S placed in the game field F.

[1-6-5] The captured image acquisition unit 120 acquires the captured image of the photographing unit 110. The reading result acquisition unit 140 acquires the reading result of the reading unit 130. The specifying unit 150 identifies the type and state of the object 100 placed on the object surface based on the captured image of the photographing unit 110 and the reading result of the reading unit 130. For example, the captured image acquisition unit 120, the reading result acquisition unit 140, and the specific unit 150 are realized by the control unit 41 of the information processing apparatus 40.

"Specifying the type of the object 100" is to specify which of the plurality of types of objects 100 the object 100 placed on the object surface is. That is, one or a plurality of objects 100 among a plurality of types of objects 100 can be placed on the target surface, and at least one of the objects 100 placed on the target surface is a plurality of types of objects. Specifying which of the objects 100 is equivalent to "identifying the type of the object 100". For example, identification information for identifying the type of the object 100 is assigned to each object 100, and specifying the identification information of the object 100 placed on the object surface is "the type of the object 100. Corresponds to "specify". When the object 100 is a game medium housed in the container, specifying the type (identification information) of the game medium housed in the container corresponds to "specifying the type of the object 100". ..

"Specifying the state of the object 100" includes, for example, specifying the position of the object 100 placed on the object surface.

Further, "specifying the state of the object 100" includes, for example, specifying how the object 100 placed on the object surface is placed (arrangement format). Specifically, specifying the orientation of the object 100 placed on the object surface corresponds to an example of "identifying the state of the object 100". The "direction" of the object 100 is the direction in which the reference direction of the object 100 is facing.

For example, when the object 100 is a rectangular object, the long side direction of the object 100 corresponds to an example of the "reference direction". In this case, specifying which direction the long side direction of the object 100 is facing corresponds to an example of "specifying the direction of the object 100". For example, the object 100 is placed with the long side direction of the object 100 facing the first direction, or the object 100 is placed with the long side direction of the object 100 facing the second direction. It corresponds to an example of "specifying the direction of the object 100". More specifically, the object 100 is placed in a vertically oriented state (a state in which it looks vertically long when viewed from a specific viewpoint (player or shooting unit 110, etc.)), or the object 100 is placed in a horizontally oriented state (specific). Identifying whether or not the object is placed in a horizontally long state when viewed from a viewpoint corresponds to an example of "specifying the orientation of the object 100".

Further, for example, the normal direction of the specific surface (surface or the like) of the object 100 corresponds to an example of the "reference direction". In this case, specifying which direction the normal direction of the specific surface (surface, etc.) of the card is facing corresponds to an example of "specifying the direction of the object 100". For example, it is possible to specify whether the object 100 is placed with the normal direction facing the first direction or the object 100 is placed with the normal direction facing the second direction. It corresponds to an example of "specifying the direction of the object 100". More specifically, the object 100 is placed with the front surface facing up (the surface can be seen from a specific viewpoint), or the back surface is facing up (the back surface can be seen from a specific viewpoint). Identifying whether it is placed inside out) corresponds to an example of "specifying the orientation of the object 100".

Further, for example, when the object 100 is a figure or a single figure housed in the housing, the front direction of the figure corresponds to an example of the "reference direction". In this case, specifying which direction the front direction of the figure is facing corresponds to an example of "specifying the direction of the object 100".

When the object 100 is a game medium housed in the container, specifying the state of the game medium housed in the container corresponds to "specifying the state of the object 100".

Further, the "state of the object 100" specified by the specific unit 150 is a matter that can be included in the wording "state of the object 100" and that affects the progress and result of the game. In other words, the "state of the object 100" specified by the specific unit 150 includes items that are meaningful in the progress of the game and the display unit 170 among the items that can be included in the wording "state of the object 100". It is an important matter for the viewer.

For example, the specifying unit 150 identifies some of the items related to the type and state of the object 100 placed on the object surface based on the captured image of the photographing unit 110, and the other items are read by the reading unit 130. Specify based on the reading result of.

[1-6-6] As shown in FIG. 22, the specific unit 150 includes a first specific unit 151 and a second specific unit 152.

[1-6-6-1] The first specifying unit 151 identifies the position of the object 100 placed on the object surface based on the captured image of the photographing unit 110. Further, the first specific unit 151 specifies the direction of the object 100 placed on the object surface based on the image taken by the image pickup unit 110.

For example, the first specific unit 151 executes machine learning based on learning data including captured image data of the target surface on which the object 100 is placed and correct answer data indicating the position and orientation of the object 100. Using the trained model generated by (a model for identifying the position and orientation of the object 100 in the captured image) to identify the position and orientation of the object 100 in the captured image. Specifies the position and orientation of the object 100 placed on the object surface.

Further, for example, the first specific unit 151 identifies the position and orientation of the object 100 placed on the object surface by detecting the object 100 from the captured image of the image capturing unit 110 using image analysis processing. You may. That is, the first specific unit 151 identifies the position and orientation of the object 100 in the photographed image by detecting the object 100 from the photographed image based on the feature information of the appearance of the object 100. May specify the position and orientation of the object 100 placed on the object surface.

In the case of the above-mentioned example of the card game, the first specifying unit 151 specifies the position of the card 60S based on the captured image of the photographing device 30. Further, the first specifying unit 151 specifies the vertical and horizontal orientation of the card 60S based on the captured image of the photographing device 30. Further, the first specific unit 151 specifies the orientation of the front and back of the card 60S based on the captured image of the photographing device 30.

[1-6-6-2] The second specifying unit 152 identifies the position of the object 100 placed on the object surface based on the reading result of the reading unit 130. Further, the second specifying unit 152 identifies the type of the object 100 placed on the target surface based on the reading result of the reading unit 130. Further, the second specifying unit 152 identifies the information written on the description surface of the object 100 placed on the object surface based on the reading result of the reading unit 130. For example, the second specifying unit 152 identifies the information written on the description surface of the object 100 placed on the target surface based on the identification result of the type of the object 100 placed on the target surface.

The "reading result of the reading unit 130" is the information read by the reading unit 130. Further, the "reading result of the reading unit 130" may be information as to whether or not the information held by the holding unit 101 could be read.

The holding unit 101 is an IC tag, and the reading unit 130 is an antenna that receives a signal transmitted from the IC tag, and has a plurality of antennas installed so as to correspond to a plurality of positions on the target surface. When included, the "reading result of the reading unit 130" is information on which of the plurality of antennas the signal transmitted from the IC tag of the object placed on the target surface is received. good. For example, when the reading unit 130 includes a plurality of IC tag readers installed at a plurality of positions corresponding to a plurality of positions on the target surface, the “reading result of the reading means” is the information stored in the IC tag. It may be information on which IC reader among the plurality of IC readers has read. Further, for example, when the reading unit 130 includes an IC tag reader provided with an antenna arranged so as to pass through a plurality of positions on the target surface, the “reading result of the reading means” means that the signal from the IC tag is the antenna. It may be information on which part was received.

In the case of the above-mentioned card game example, the information read by the reading device 20 (information stored in the IC tag 73) corresponds to an example of the "reading result of the reading unit 130". Further, the information on whether or not the reading device 20 has read the information stored in the IC tag 73 also corresponds to an example of the “reading result of the reading unit 130”. Further, which of the plurality of reading devices 20-1 to 20-30 read the information stored in the IC tag 73 (in other words, the signal from the IC tag 73 is read from the plurality of reading devices 20-1 to 20-1 to 20-30. The information (which of 20-30 was received) also corresponds to an example of the "reading result of the reading unit 130". In the case of the modification shown in FIG. 21, the information on which first antenna 21 and second antenna 22 the signal from the IC tag 73 is received corresponds to an example of the “reading result of the reading unit 130”.

In the case of the above-mentioned card game example, the second specifying unit 152 specifies the position and type of the card 60S placed on the game field F based on the reading result of the reading device 20.

For example, the second specifying unit 152 identifies the position of the card 60S based on which reading device 20 has read the information stored in the IC tag 73 of the card 60S. That is, the second specifying unit 152 corresponds to the position of the reading device 20 (reading device 20 for receiving the signal transmitted from the IC tag 73 of the card 60S) that has read the information stored in the IC tag 73 of the card 60S. The position on the game field F to be played is specified as the position of the card 60S. For example, when the information stored in the IC tag 73 of the card 60S is read by the reading device 20-10, the second specifying unit 152 places the zone Z10 associated with the reading device 20-10 by the card 60S. It is specified as the zone Z that has been drawn.

In the case of the modification shown in FIG. 21, the second specific unit 152 determines the position of the card 60S based on which part of the antenna the signal from the IC tag 73 of the card 60S is received. It may be specified. That is, the second specifying unit 152 may specify the position on the game field F corresponding to the portion of the antenna in which the signal from the IC tag 73 of the card 60S is received as the position of the card 60S. For example, the second specific unit 152 receives the signal from the IC tag 73 of the card 60S, the first antenna 21 and the second antenna 22 (in other words, the first antenna 21 and the second antenna 22 having the strongest received signal strength). The zone Z including the intersection of the above may be specified as the zone Z in which the card 60S is placed.

Further, the second specifying unit 152 identifies the type of the card 60S placed in the game field F based on the information read by the reading device 20.

For example, when the association process shown in FIG. 10 is executed, the association data D1 (FIG. 11) in which the tag ID and the card ID are associated is stored in the storage unit 42. In this case, the second specifying unit 152 identifies the card ID associated with the tag ID read by the reading device 20 based on the association data D1.

Further, for example, when the association process shown in FIG. 12 is executed, the card ID of the card 60S is stored in the IC tag 73 of the card 60S, and the card ID is read by the reading unit 130. In this case, the second specifying unit 152 acquires the card ID read by the reading device 20.

[1-6-6-3] A plurality of objects 100 may be placed on the object surface. In this case, for each of the plurality of objects 100, the specific result of the first specific unit 151 based on the captured image of the image capture unit 110 can be obtained. Similarly, for each of the plurality of objects 100, the specific result of the second specific unit 152 based on the reading result of the reading unit 130 can also be obtained. In such a case, it is necessary to specify the combination of the specific result of the first specific unit 151 and the specific result of the second specific unit 152 regarding the same object 100 placed on the target surface.

In this respect, the specific result of the first specific unit 151 and the specific result of the second specific unit 152 commonly include the specific result regarding the predetermined item of the object 100, and the specific unit 150 is the first specific unit. By collating the specific result regarding the above-mentioned predetermined items commonly included in the specific result of 151 and the specific result of the second specific unit 152, the first specific unit 151 regarding the same object 100 placed on the object surface The combination of the specific result and the specific result of the second specific unit 152 is specified.

In the present embodiment, since the specific result regarding the position of the object 100 (an example of the above-mentioned predetermined item) is commonly included in the specific result of the first specific unit 151 and the specific result of the second specific unit 152, the specific unit is included. Reference numeral 150 indicates a specific result of the first specific unit 151 regarding the same object 100 placed on the target surface based on the position specified by the first specific unit 151 and the position specified by the second specific unit 152. And the specific result of the second specific unit 152 are specified.

That is, the specific unit 150 is the specific result of the first specific unit 151 and the specific result of the second specific unit 152 based on the comparison between the position specified by the first specific unit 151 and the position specified by the second specific unit 152. The specific result is specified as a specific result regarding the same object 100 placed on the object surface.

In other words, the specific unit 150 is the type specified by the first specific unit 151 and the second specific unit when the position specified by the first specific unit 151 and the position specified by the second specific unit 152 correspond to each other. It is determined that the combination with the orientation specified by unit 152 is the specific result for the same object 100 placed on the object surface.

"When the position specified by the first specific unit 151 corresponds to the position specified by the second specific unit 152" is specified by the position specified by the first specific unit 151 and the second specific unit 152. In this case, it can be considered that the positions are the same. For example, the position specified by the first specific unit 151 and the position specified by the second specific unit 152 both correspond to the same region. It can be rephrased as a case.

For example, in the above-mentioned example of the card game, a plurality of zones Z1 to Z30 (partial areas) are defined in the game field F as an area for placing the card 60S, and a plurality of reading devices 20-1 to 20-30 are defined. Is installed so as to correspond to a plurality of zones Z1 to Z30. When the card 60S is placed in any of the zones Z, the zone Z in which the card 60 is placed can be specified from the captured image of the photographing device 30. Separately, the zone Z in which the card 60 is placed can be specified from the reading result of the reading device 20. That is, the zone Z corresponding to the reading device 20 that has read the information stored in the IC tag 73 of the card 60S is specified as the zone Z in which the card 60S is placed. In such a case, "when the position specified by the first specific unit 151 and the position specified by the second specific unit 152 correspond to each other" means the zone Z specified from the captured image of the photographing device 30 and the zone Z. This is the case where the zone Z specified from the reading result of the reading device 20 is the same.

In addition, "when the position specified by the first specific unit 151 and the position specified by the second specific unit 152 correspond to each other" means the position specified from the captured image of the photographing unit 110 and the reading unit 130. It may be the case that the distance from the position specified from the reading result is less than the threshold value.

[1-6-6-4] The second specific unit 152 is a type of card 60S (first card) placed on the game field F with other cards 60S (second cards) stacked. Can be specified based on the information read by the reading unit 130 from the IC tag 73 of the card 60S (first card). For example, as in the situation shown in FIG. 7, even when the card bundle 600-1 is placed in the zone Z7, the second specific unit 152 is a plurality of cards 60S included in the card bundle 600-1. Each type can be specified based on the information read by the reading unit 130 from each IC tag 73 of the plurality of cards 60S.

[1-6-7] The display control unit 160 causes the display unit 170 to display an object corresponding to the object 100 placed on the target surface. For example, the display control unit 160 is realized by at least one of the control unit 41 of the information processing device 40 or the control unit 51 of the display terminal device 50. The display unit 170 is realized by at least one of the display unit 45 of the information processing device 40 or the display unit 55 of the display terminal device 50.

The "object" is displayed on the display unit 170. For example, an "object" is an object that imitates an object 100. That is, the "object" is an image of the object 100. The "object" may be an object (text, icon, etc.) indicating the type and name of the object 100, or the content of the influence on the progress and result of the game.

For example, the display control unit 160 causes the display unit 170 to display an object corresponding to the type of the object 100 specified by the specific unit 150 in a state corresponding to the state of the object 100 specified by the specific unit 150. Specifically, the display control unit 160 corresponds to the object corresponding to the type of the object 100 specified by the specific unit 150 to the position (position on the target surface) of the object 100 specified by the specific unit 150. Display at the display position. Further, the display control unit 160 displays the object corresponding to the type of the object 100 specified by the specific unit 150 in the direction corresponding to the direction of the object 100 specified by the specific unit 150.

Further, for example, the display control unit 160 causes the display unit 170 to display an object corresponding to the type of the object 100 specified by the specific unit 150 according to the state of the object 100 specified by the specific unit 150.

Specifically, the display control unit 160 corresponds to the type of the object 100 specified by the specific unit 150 as an object corresponding to the object 100 according to the state of the object 100 specified by the specific unit 150. It is determined whether or not to display the object to be displayed on the display unit 170.

That is, the display control unit 160 determines whether or not the state of the object 100 specified by the specific unit 150 is a predetermined state. Then, when it is determined that the state of the object 100 specified by the specific unit 150 is not a predetermined state, the display control unit 160 determines the object specified by the specific unit 150 as an object corresponding to the object 100. Objects corresponding to 100 types are displayed on the display unit 170. On the other hand, when it is determined that the state of the object 100 specified by the specific unit 150 is a predetermined state, the display control unit 160 determines the object specified by the specific unit 150 as an object corresponding to the object 100. The object corresponding to the type of the object 100 is not displayed on the display unit 170. In this case, the display control unit 160 causes the display unit 170 to display an object that does not depend on the type of the object 100 specified by the specific unit 150 as an object corresponding to the object 100.

Further, the display control unit 160 specifies when the object 100 is placed on the target surface so that the above-mentioned description surface (the surface on which the information is described) of the object 100 and the target surface face each other. The display unit 170 is displayed according to the information written on the description surface of the object 100 specified by the unit 150 (second specific unit 152).

"When the object 100 is placed on the object surface so that the description surface and the object surface face each other" means that the object 100 is placed on the object surface so that the description surface cannot be seen from the photographing unit 110. If it is placed.

For example, when the object 100 is a game medium housed in the container, "when the object 100 is placed on the object surface so that the description surface and the object surface face each other" means. This is a case where the object 100 is placed on the object surface so that the description surface of the game medium and the object surface face each other through the housing. In other words, the object 100 is placed on the object surface so that the description surface of the game medium and the object surface are in contact with each other via the accommodation body.

When the object 100 is a single game medium, "when the object 100 is placed on the target surface so that the description surface and the target surface face each other" means the description surface of the game medium. This is a case where the object 100 (game medium) is placed on the object surface so that the object surface and the object surface are in contact with each other.

"Displaying the display corresponding to the information written on the description surface on the display unit 170" means, for example, displaying the information written on the description surface of the object 100 on the display unit 170. In this case, all of the information written on the written surface may be displayed on the display unit 170, or a part of the information written on the written surface may be displayed on the display unit 170.

Specifically, "displaying the display according to the information written on the description surface on the display unit 170" means displaying an object imitating the description surface of the object 100 on the display unit 170. In other words, the display unit 170 displays an object formed by imaging the description surface of the object 100.

For example, when the type of the object 100 or the content of the influence on the progress or result of the game is described on the description surface, "the display unit 170 displays the display according to the information described on the description surface". "" May mean that the display unit 170 displays a text or a symbol indicating the type of the object 100 or the content of the influence on the progress or result of the game. In this case, the method of displaying the type of the object on the display unit 170, the content of the influence on the progress or the result of the game, and the like may be different from the method of displaying on the description surface.

Further, for example, when the type of the object 100 is described on the description surface, "displaying the display according to the information described on the description surface on the display unit 170" is a matter not described on the description surface. Therefore, the display unit 170 may display a text or a pattern indicating a matter specified from the type of the object 100 (for example, the content of the influence of the object 100 on the progress or result of the game).

In addition, "to display the display corresponding to the information written on the written surface on the display unit 170" means that the data related to the display according to the information written on the written surface is transmitted to another device, so that the written surface is displayed. The display corresponding to the information described in may be displayed on the display unit 170 of the other device.

The display control unit 160 is the target specified by the specific unit 150 (second specific unit 152) at least when the object 100 is placed on the target surface so that the description surface and the target surface face each other. A display corresponding to the information written on the description surface of the object 100 is displayed on the display unit 170.

In the display control unit 160, when the object 100 is placed on the target surface so that the description surface and the target surface do not face each other (that is, the object 100 is placed on the target surface with the description surface visible). In the case of), the display unit 170 may be displayed according to the information written on the description surface of the object 100 specified by the specific unit 150 (second specific unit 152). In that case, the display unit 170 may display a display corresponding to the information written on the description surface of the object 100, which is specified by another specific method. For example, when the object 100 is placed on the target surface so that the description surface and the target surface do not face each other (that is, when the object 100 is placed on the target surface with the description surface visible). The information written on the description surface of the object 100 may be read, and the display unit 170 may display the display according to the read information. For example, when the object 100 is placed on the target surface in a state where the description surface is reflected in the captured image of the photographing unit 110, the information written on the description surface of the object 100 is obtained from the captured image of the photographing unit 110. It may be specified, and the display according to the information specified in this way may be displayed on the display unit 170.

Further, the display control unit 160 received a predetermined operation regarding the object corresponding to the object 100 in a state where the object 100 is placed on the object surface so that the description surface and the object surface face each other. In this case, the display unit 170 may display a display according to the information written on the description surface of the object 100.

The "predetermined operation" is, for example, an operation of designating (or selecting) an object. The "predetermined operation" may be an operation for specifying any of the objects, and may be an operation for designating the type, position, or orientation of the object. Based on such an operation, the object corresponding to the specified type, position, or orientation is specified. For example, based on such an operation, a process of displaying the display corresponding to the information written on the description surface of the object 100 corresponding to the object on the display unit 170 is executed.

In the case of the above-mentioned card game example, each of the parts PB-1 and PB-2 shown in FIG. 8 corresponds to an example of an “object”, and the part PC shown in FIG. 9 is “information written on the description surface”. Corresponds to an example of "display according to". In the case of the above-mentioned card game example, the display control unit 160 causes the display unit 170 to display the game field image G.

For example, the display control unit 160 determines whether the orientation of the card 60S specified by the first identification unit 151 is face up or face down.

Then, when the orientation of the card 60S specified by the first specific unit 151 is face up, the display control unit 160 uses the card as a part to be associated with the card 60S, such as the part PB-2 shown in FIG. The image of the surface 61 of the 60S (that is, the image corresponding to the type of the card 60S specified by the second specific unit 152) is the position of the card 60S specified by the first specific unit 151 or the second specific unit 152. It is displayed at the position in the game field image G corresponding to.

On the other hand, when the orientation of the card 60S specified by the first specific unit 151 is face down, the display control unit 160 has the same as the part PB-2 shown in FIG. 8 as a part associated with the card 60S.

[2. Second Embodiment] The second embodiment of the present invention will be described.

The second embodiment is different from the first embodiment in that the orientation (vertical / horizontal orientation) of the card is specified based on the information stored in the IC tag. Hereinafter, the differences from the first embodiment will be described. In the following, the same reference numerals will be used for the same elements as those of the first embodiment, and the description thereof will be omitted.

[2-1. Overview] FIG. 23 shows an example of the sleeve 70A of the second embodiment. Similar to the sleeve 70 of the first embodiment, the surface portion 71A of the sleeve 70A is transparent so that the surface 61 of the card 60 housed in the sleeve 70A can be visually recognized from the outside of the sleeve 70A. Further, like the sleeve 70 of the first embodiment, the back surface portion 72A of the sleeve 70A is opaque and has an appearance common to all the sleeves 70A.

As shown in FIG. 23, the sleeve 70A includes a first IC tag 73A-1 and a second IC tag 73A-2. The first IC tag 73A-1 and the second IC tag 73A-2 are provided on the inner surface of the back surface portion 72A. For example, the installation positions of the first IC tag 73A-1 and the second IC tag 73A-2 on the inner surface of the back surface portion 72A are different. For example, the installation positions of the first IC tag 73A-1 and the second IC tag 73A-2 are the difference in the first direction (for example, the vertical direction) between the positions and the second direction (for example, the horizontal direction) between the positions. It is set so that the difference in direction) is different.

The tag ID of the first IC tag 73A-1 is stored in the first IC tag 73A-1, and the tag ID of the second IC tag 73A-2 is stored in the second IC tag 73A-2. Since the first IC tag 73A-1 and the second IC tag 73A-2 are separate IC tags, their tag IDs are different from each other.

In the second embodiment, the card 60 is housed in the sleeve 70A as described above. In the following, the card 60 housed in the sleeve 70A will be referred to as “card 60SA” for convenience in order to distinguish it from the card 60 alone. In other words, when the card 60 is housed in the sleeve 70A, the card 60 and the sleeve 70A are regarded as one object and are described as "card 60SA".

Further, in the second embodiment, the first IC tag 73A-1 and the first IC tag 73A-1 and the second IC tag 73A-1 can be specified so that the positions of the first IC tag 73A-1 and the second IC tag 73A-2 of the card 60SA placed on the game field F can be specified. A reading device 20 having a plurality of antennas, which are antennas for receiving signals transmitted from each of the 2 IC tags 73A-2 and are installed so as to correspond to a plurality of positions on the game field F, is installed. To. For example, in the second embodiment, a reading device 20 including a plurality of first antennas 21 and a plurality of second antennas 22 as shown in FIG. 21 is installed.

That is, when the card 60SA is placed on the game field F, the first antenna 21 and the second antenna 22 that have received the signal from the first IC tag 73A-1 (ID tag of the first IC tag 73A-1) By specifying the combination (in other words, the combination of the first antenna 21 and the second antenna 22 having the strongest signal strength received from the first IC tag 73A-1), the first IC tag 73A-1 on the game field F The position can be specified. For example, the intersection of the first antenna 21 and the second antenna 22 (in other words, the first antenna 21 and the second antenna 22 having the strongest received signal strength) that received the signal from the first IC tag 73A-1 is set as the game field F. It can be specified as the position of the first IC tag 73A-1 above.

Similarly, the combination of the first antenna 21 and the second antenna 22 (the strength of the signal received from the second IC tag 73A-2) that received the signal from the second IC tag 73A-2 (ID tag of the second IC tag 73A-2). Is the strongest combination of the first antenna 21 and the second antenna 22), so that the position of the second IC tag 73A-2 on the game field F can be specified.

FIG. 24 shows the case where the card 60SA is placed vertically on the game field F, and FIG. 25 shows the case where the card 60SA is placed horizontally on the game field F. Here, as shown in FIGS. 24 and 25, the predetermined point (for example, the lower left point) of the game field F is the origin O, the horizontal direction of the game field F is the X-axis direction, and the vertical direction of the game field F is the Y-axis direction. Assume the coordinate system to be. Further, the position of the first IC tag 73A-1 on the game field F is (X1, Y1), and the position of the second IC tag 73A-2 on the game field F is (X2, Y2).

As shown in FIG. 24, when the card 60SA is placed vertically, the long side direction of the card 60SA is parallel (or substantially parallel) to the Y-axis direction, and the card 60SA is vertically long. .. In this case, the absolute value of the difference between Y1 and Y2 (| Y1-Y2 |) is larger than the absolute value of the difference between X1 and X2 (| X1-X2 |). Therefore, when the positions of the specified first IC tag 73A-1 and the second IC tag 73A-2 have a relationship of | Y1-Y2 |> | X1-X2 |, the card 60SA is placed vertically. Can be identified as being.

On the other hand, as shown in FIG. 25, when the card 60SA is placed sideways, the long side direction of the card 60SA becomes parallel (or substantially parallel) to the X-axis direction, and the card 60SA becomes horizontally long. Become. In this case, the absolute value of the difference between X1 and X2 (| X1-X2 |) is larger than the absolute value of the difference between Y1 and Y2 (| Y1-Y2 |). Therefore, when the positions of the specified first IC tag 73A-1 and the second IC tag 73A-2 have a relationship of | X1-X2 |> | Y1-Y2 |, the card 60SA is placed sideways. Can be specified.

As described above, in the second embodiment, the positions of the first IC tag 73A-1 and the second IC tag 73A-2 are specified based on the reading result of the reading device 20, and the card 60SA is based on the positional relationship between them. You can specify the vertical and horizontal orientation of.

[2-2. Process] A process executed by the system 1A according to the second embodiment will be described.

[2-2-1] Also in the second embodiment, the association process similar to the association process shown in FIG. 10 is executed. However, in step S404, the control unit 41 acquires the tag IDs of the first IC tag 73A-1 and the second IC tag 73A-2, and in step S406, the control unit 41 becomes the first IC tag 73A-1. Both tag IDs with the second IC tag 73A-2 are registered in the "tag ID" field of the association data D1.

[2-2-2] Also in the second embodiment, an association process similar to the association process shown in FIG. 12 may be executed. However, in step S424, the control unit 41 writes the card ID specified in step S422 to both the first IC tag 73A-1 and the second IC tag 73A-2.

[2-2-3] Also in the second embodiment, a specific process similar to the specific process shown in FIG. 13 is executed.

In the second embodiment, in step S432, the control unit 41 specifies the position of the card 60SA and the orientation of the front and back sides, and does not specify the vertical and horizontal orientation of the card 60SA. In this case, the specific result in step S432 is registered in the first specific result data D2A. FIG. 26 shows an example of the first specific result data D2A in the second embodiment. As shown in FIG. 26, the first specific result data D2A includes the "region ID" and "front and back flags" fields. The "region ID" and "front and back flags" fields are the same as the "region ID" and "front and back flags" fields of the first specific result data D2 of the first embodiment.

Further, in the second embodiment, in step S436, the control unit 41 specifies the card ID, the position, and the vertical / horizontal orientation of the card 60SA placed in the game field F.

For example, the control unit 41 refers to the association data D1 and identifies a card ID associated with the tag ID read from the first IC tag 73A-1 and the tag ID read from the second IC tag 73A-2.

Further, when the tag ID read from the first IC tag 73A-1 and the ID tag read from the second IC tag 73A-2 are associated with the same card ID, the control unit 41 controls these first ICs. It is considered that the tag 73A-1 and the second IC tag 73A-2 are provided on the same card 60SA. Then, the control unit 41 executes the processing as described below with respect to the first IC tag 73A-1 and the second IC tag 73A-2 provided in the same card 60SA.

That is, the control unit 41 is a combination of the first antenna 21 and the second antenna 22 that have received the signal (tag ID) from the first IC tag 73A-1 (in other words, the strength of the signal received from the first IC tag 73A-1). Is the strongest combination of the first antenna 21 and the second antenna 22), thereby specifying the position of the first IC tag 73A-1 on the game field F.

Similarly, the control unit 41 is a combination of the first antenna 21 and the second antenna 22 (in other words, the signal received from the second IC tag 73A-2) that has received the signal (tag ID) from the second IC tag 73A-2. By specifying the combination of the first antenna 21 and the second antenna 22 having the strongest strength), the position of the second IC tag 73A-2 on the game field F is specified.

Then, the control unit 41 specifies the midpoint between the position of the first IC tag 73A-1 and the position of the second IC tag 73A-2 as the position of the card 60SA, and which zone Z includes the specified position. By determining, the zone Z in which the card 60SA is placed is specified.

Further, the control unit 41 specifies the vertical and horizontal orientation of the card 60SA based on the positional relationship between the position of the first IC tag 73A-1 and the position of the second IC tag 73A-2.

For example, when the vertical difference (| Y2-Y1 |) between the position of the first IC tag 73A-1 and the position of the second IC tag 73A-2 is larger than the horizontal difference (| X2-X1 |). The control unit 41 identifies that the card 60SA is placed vertically. On the other hand, when the vertical difference (| Y2-Y1 |) between the position of the first IC tag 73A-1 and the position of the second IC tag 73A-2 is smaller than the horizontal difference (| X2-X1 |). The control unit 41 identifies that the card 60SA is placed sideways.

In the second embodiment, the specific result in step S436 is registered in the second specific result data D3A. FIG. 27 shows an example of the second specific result data D3A. As shown in FIG. 27, the second specific result data D3A includes "zone ID", "card ID", and "vertical and horizontal flag" fields. The "zone ID" field is the same as the "zone ID" field of the game field status data D4 of the first embodiment. The "card ID" field is the same as the "card ID" field of the second specific result data D3 of the first embodiment. The "vertical and horizontal flag" field is the same as the "vertical and horizontal flag" field of the first specific result data D2 of the first embodiment.

Further, in the second embodiment, in step S438, the control unit 41 generates the game field status data D4 based on the first specific result data D2A and the second specific result data D3A. The game field status data D4 is the same as that of the first embodiment. Further, the process of step S438 is the first embodiment except that the vertical / horizontal flag registered in the “vertical / horizontal flag” field of the second specific result data D3A is registered in the “vertical / horizontal flag” field of the game field status data D4. It is the same as step S438 of.

[2-2-4] Also in the second embodiment, the display control process shown in FIG. 18 and the process shown in FIG. 19 are executed.

[2-3. Effect] According to the second embodiment, the vertical and horizontal orientation of the card 60SA placed in the game field F can be specified based on the reading result of the reading device 20.

[2-4. Modification example] A modification of the second embodiment will be described.

[2-4-1] In the embodiment described above, the installation positions of the first IC tag 73A-1 and the second IC tag 73A-2 are not limited to the example shown in FIG. 23. The installation positions of the first IC tag 73A-1 and the second IC tag 73A-2 are those if the positions of the first IC tag 73A-1 and the second IC tag 73A-2 of the card 60SA placed on the game field F can be specified. It may be set so as to have a positional relationship so that the vertical and horizontal orientation of the card 60SA can be specified from the positional relationship.

For example, the first IC tag 73A-1 may be installed at the upper left position on the back surface portion 72A, and the first IC tag 73A-2 may be installed at the upper right position on the back surface portion 72A. Further, for example, the first IC tag 73A-1 may be installed at the upper left position on the back surface portion 72A, and the first IC tag 73A-2 may be installed at the lower left position on the back surface portion 72A.

[2-4-2] In addition to the first IC tag 73A-1 and the second IC tag 73A-2, one or more IC tags may be installed on the back surface portion 72A. That is, three or more IC tags may be installed on the back surface portion 72A, and the vertical and horizontal orientation of the card 60SA may be specified based on the positional relationship of the three or more IC tags.

[2-4-3] Also in the second embodiment, in step S432, the control unit 41 may specify the vertical and horizontal orientation of the card 60SA. That is, the control unit 41 may specify the vertical / horizontal orientation of the card 60SA from the captured image of the photographing device 30, and may also specify the vertical / horizontal orientation of the card 60SA from the reading result of the reading device 20. In this case, by collating the vertical / horizontal orientation specific result obtained from the captured image of the photographing device 30 with the vertical / horizontal orientation specific result obtained from the reading result of the reading device 20, the vertical / horizontal orientation specific result is obtained. You may try to improve the accuracy of.

[2-4-4] In the embodiment described above, the sleeve 70A (back surface portion 72A) includes the first IC tag 70A-1 and the second IC tag 70A-2. For example, the object 80 shown in FIG. 20. A sheet-like object accommodated in the sleeve 70A together with the card 60 may include the first IC tag 70A-1 and the second IC tag 70A-2. In this case, the sheet-shaped object and the card 60 housed in the sleeve 70A correspond to the card 60SA.

[2-4-5] The card 60 itself (for example, the back surface 62) may include the first IC tag 70A-1 and the second IC tag 70A-2.

[2-5. Functional elements] FIG. 28 is a functional block diagram for explaining the functional elements included in the system 1A according to the second embodiment. In FIG. 28, the functional elements that are the same as the functional elements of the first embodiment (shooting unit 110, captured image acquisition unit 120, reading unit 130, reading result acquisition unit 140, display control unit 160, and display unit 170). 22 has the same reference numerals as those in FIG. 22, and the description of these functional elements is omitted here, and the object 100A and the specific portion 150A will be described. Further, regarding the explanation of the wording, the explanation will be omitted with respect to the point overlapping with the first embodiment.

[2-5-1] First, the object 100A will be described. Here, the difference between the object 100A and the object 100 in the first embodiment will be described.

The object 100A includes a first holding portion 101A and a second holding portion 102A provided so as to have a predetermined positional relationship with the first holding portion 101A. If the positions of the first holding portion 101A and the second holding portion 102A of the object 100A placed on the target surface can be specified, the first holding portion 101A and the second holding portion 102A can identify the positions of the target 100A from those positions. It has a positional relationship that allows the orientation to be specified. For example, when the object 100A is placed on the target surface in the first orientation, the positional relationship between the first holding portion 101A and the second holding portion 102A on the target surface becomes the first positional relationship, and the object 100A becomes When placed on the target surface in a second orientation different from the first orientation, the positional relationship between the first holding portion 101A and the second holding portion 102A on the target surface is different from the first positional relationship. The positions of the first holding portion 101A and the second holding portion 102A in the object 100A are set so as to have a positional relationship.

Specific information for specifying the type or state of the object 100A placed on the object surface is held in the first holding unit 101A and the second holding unit 102A. The information held in the first holding unit 101A and the second holding unit 102A is read by the reading unit 130. In the present embodiment, the first IC tag 73A-1 corresponds to the first holding portion 101A, and the second IC tag 73A-2 corresponds to the second holding portion 102A.

[2-5-2] The specific unit 150A will be described. The specific unit 150A includes a first specific unit 151A and a second specific unit 152A.

The first specific unit 151A specifies the position and orientation of the object 100A based on the captured image of the photographing unit 110. For example, the first specific unit 151A specifies the position of the object 100A and the orientation of the front and back sides in the same manner as the first specific unit 151 of the first embodiment.

The second specifying unit 152A specifies the position, type, and orientation of the object 100A based on the reading result of the reading unit 130.

The second specific unit 152A specifies the type of the object 100A in the same manner as the second specific unit 152 of the first embodiment.

As described above, in the second embodiment, the reading unit 130 is a signal transmitted from each of the first holding unit 101A (first IC tag 73A-1) and the second holding unit 102A (second IC tag 73A-2). The antenna is provided with a plurality of antennas (a plurality of first antennas 21 and a plurality of second antennas 22) installed so as to correspond to a plurality of positions on the game field F.

The second specific unit 152A is transmitted from each of the first holding unit 101A (first IC tag 73A-1) and the second holding unit 102A (second IC tag 73A-2) of the object 100A placed on the target surface. The position and orientation of the object 100A placed on the object surface is specified based on which of the plurality of antennas the signal is received.

In addition, in order to be able to distinguish whether the signal received by the antenna is the signal transmitted from the first holding unit 101A or the second holding unit 102A, the first holding unit 101A and the second holding unit 102A The information held in each contains different information, and the signals transmitted from each of the first holding unit 101A and the second holding unit 102A include different information. For example, the identification information of the first holding unit 101A (tag ID of the first IC tag 73A-1) is held by the first holding unit 101A (first IC tag 73A-1), and the identification information of the second holding unit 102A (second IC). The tag ID of the tag 73A-2) is held by the second holding unit 102A (second IC tag 73A-2).

[2-5-3] In the case of the above-mentioned example of the card game, the card 60SA corresponds to the object 100A. In the case of a modification in which the card 60 itself is provided with the first IC tag 73A-1 and the second IC tag 73A-2, the card 60 alone corresponds to the object 100A.

The second specific unit 152A is the first antenna 21 and the second antenna 22 that have received the signal (tag ID of the first IC tag 73A-1) from the first IC tag 73A-1 of the card 60SA placed in the game field F. By specifying the combination (the combination of the first antenna 21 and the second antenna 22 having the strongest signal strength received from the first IC tag 73A-1), the position of the first IC tag 73A-1 on the game field F is specified. do. Similarly, the second specific unit 152A receives the signal (tag ID of the second IC tag 73A-2) from the second IC tag 73A-2 of the card 60SA placed in the game field F, and the first antenna 21 and the second. By specifying the combination of the two antennas 22 (the combination of the first antenna 21 and the second antenna 22 having the strongest signal strength received from the second IC tag 73A-2), the second IC tag 73A-2 on the game field F Also specify the position of. Then, the second specifying unit 152A specifies the vertical and horizontal orientation of the card 60SA based on the positional relationship between the first IC tag 73A-1 and the second IC tag 73A-2 on the game field F.

As described above, in the second embodiment, the tag ID of the first IC tag 73A-1 stored in the first IC tag 73A-1 and the tag ID of the second IC tag 73A-2 stored in the second IC tag 73A-2. The positions of the first IC tag 73A-1 and the second IC tag 73A-2 are specified on the game field F, and the positions of the first IC tag 73A-1 and the second IC tag 73A-2 on the game field F are specified. Since the vertical and horizontal orientation of the card 60SA is specified based on the relationship, the tag ID of the first IC tag 73A-1 and the tag ID of the second IC tag 73A-2 are "the basis for specifying the state of the object 100A". It corresponds to "information that becomes".

[3. Third Embodiment] The third embodiment of the present invention will be described.

The third embodiment is different from the first embodiment in that the orientation (front and back orientation) of the card is specified based on the information stored in the IC tag. Hereinafter, the differences from the first embodiment will be described. In the following, the same reference numerals will be used for the same elements as those of the first embodiment, and the description thereof will be omitted.

[3-1. Overview] FIG. 29 shows an example of the sleeve 70B of the third embodiment. FIG. 29 shows a cross-sectional view of the sleeve 70B when the sleeve 70B is viewed from the side. Similar to the sleeve 70 of the first embodiment, the surface portion 71B of the sleeve 70B is transparent so that the surface 61 of the card 60 housed in the sleeve 70B can be visually recognized from the outside of the sleeve 70B. Further, like the sleeve 70 of the first embodiment, the back surface portion 72B of the sleeve 70B is opaque and has an appearance common to all the sleeves 70B.

As shown in FIG. 29, the sleeve 70B includes a first IC tag 73B-1, a second IC tag 73B-2, and a blocking surface portion 74B. For example, the blocking surface portion 74B has the same shape and size as the back surface portion 72B of the sleeve 70B (or substantially the same). The upper end and the lower end of the cutoff surface portion 74B are connected to the upper end and the lower end of the back surface portion 72B, and the cutoff surface portion 74B is fixed to the sleeve 70B.

The first surface 75B of the cutoff surface portion 74B faces the surface portion 71B of the sleeve 70B. The first IC tag 73B-1 is provided on the first surface 75B. Therefore, the first IC tag 73B-1 faces the surface portion 71B of the sleeve 70B. The second surface 76B of the cutoff surface portion 74B faces the back surface portion 72B of the sleeve 70B. The second surface 76B is provided with a second IC tag 73B-2. Therefore, the second IC tag 73B-2 faces the back surface portion 72B of the sleeve 70B.

The tag ID of the first IC tag 73B-1 is stored in the first IC tag 73B-1, and the tag ID of the second IC tag 73B-2 is stored in the second IC tag 73B-2. Since the first IC tag 73B-1 and the second IC tag 73B-2 are separate IC tags, their tag IDs are different from each other.

The blocking surface portion 74B is formed of a material (for example, a magnetic material) that hinders transmission / reception of signals between the first IC tag 73B-1 and the second IC tag 73B-2 and the reading device 20. Therefore, the signal transmitted from the second surface 76B (back surface portion 72B) side is received by the first IC tag 73B-1, and the signal from the first IC tag 73B-1 is received by the second surface 76B (back surface portion 72B). ) Is prevented from being transmitted to the blocking surface portion 74B. Similarly, the signal transmitted from the first surface 75B (surface portion 71B) side is received by the second IC tag 73B-2, and the signal from the second IC tag 73B-2 is received by the first surface 75B (surface portion 71B). ) Is prevented from being transmitted to the blocking surface portion 74B.

The card 60 is housed in the space between the surface portion 71B and the cutoff surface portion 74B of the sleeve 70B. In the following, the card 60 housed in the sleeve 70B will be referred to as “card 60SB” for convenience in order to distinguish it from the card 60 alone. In other words, when the card 60 is housed in the sleeve 70B, the card 60 and the sleeve 70B are regarded as one object and are described as "card 60SB".

When the card 60SB is placed face up in the zone Z, the card 60SB is placed so that the back surface portion 72B of the card 60SB and the game field F are in contact with each other. In this case, since the transmission / reception of the signal between the reading device 20 installed under the zone Z and the first IC tag 73B-1 is hindered by the blocking surface portion 74B (magnetic material or the like), the signal is stored in the first IC tag 73B-1. The added information (tag ID, etc.) is not read by the reading device 20. As a result, information is read by the reading device 20 only from the second IC tag 73B-2.

On the other hand, when the card 60SB is placed face down in the zone Z, the card 60SB is placed so that the surface portion 71B of the card 60SB and the game field F are in contact with each other. In this case, since the transmission / reception of the signal between the reading device 20 installed under the zone Z and the second IC tag 73B-2 is hindered by the cutoff surface portion 74B (magnetic material or the like), the second IC tag 73B-2 is used. The stored tag ID is not read by the reading device 20. As a result, information (tag ID and the like) is read by the reading device 20 only from the first IC tag 73B-1.

In this way, when the card 60SB is placed face up, information is read by the reading device 20 only from the second IC tag 73B-2. Similarly, when the card 60SB is placed face down, information is read by the reading device 20 only from the first IC tag 73B-1. Therefore, the orientation of the front and back of the card 60SB can be specified based on which of the first IC tag 73B-1 and the second IC tag 73B-2 has read the stored information.

[3-2. Process] A process executed by the system 1B according to the third embodiment will be described.

[3-2-1] FIG. 30 shows an example of the association processing of the third embodiment. In the third embodiment, the association process shown in FIG. 30 is executed instead of the association process shown in FIG.

For example, the player places one card 60SB from his or her deck vertically and face up in a predetermined zone Z (eg, zone Z11, etc.) of the game field F. In this state, the association process shown in FIG. 30 is executed.

As shown in FIG. 30, first, the control unit 41 of the information processing apparatus 40 acquires a photographed image of the photographing apparatus 30 (S400B). Then, the control unit 41 identifies the card ID of the card 60SB shown in the captured image from the captured image (S402B). Steps S400B and S402B are the same as steps S400 and S402 in FIG.

Further, the control unit 41 acquires the tag ID read by the reading device 20 (S404B). When the card 60SB is placed face up, the tag ID stored in the second IC tag 73B-2 is read by the reading device 20, and the read tag ID is supplied to the information processing device 40. The control unit 41 acquires the tag ID supplied in this way.

After executing step S404B, the control unit 41 outputs a flipping request notification indicating that the player is requested to flip the card 60SB (S406B). For example, the control unit 41 displays an image showing the inside-out request notification on the display unit 45. Alternatively, the control unit 41 causes the voice output unit 46 to output a voice indicating the inside-out request notification.

In response to the inside-out request notification, the player turns the card 60SB placed face down in the zone Z by turning it over. In this state, the processes after step S408B are executed.

That is, the control unit 41 acquires the tag ID read by the reading device 20 (S408B). When the card 60SB is placed face down, the tag ID stored in the first IC tag 73B-1 is read by the reading device 20, and the read tag ID is supplied to the information processing device 40. The control unit 41 acquires the tag ID supplied in this way.

Then, the control unit 41 registers the association between the card ID specified in step S402B and the tag ID acquired in steps S404B and S408B in the association data D1B (S410B).

FIG. 31 shows an example of the association data D1B. As shown in FIG. 31, the association data D1B includes "card ID" and "tag ID" fields. The "card ID" field is the same as the "card ID" field of the association data D1 in the first embodiment. The "tag ID" field includes "face-up" and "face-down" fields as subfields. The "face-up" field is a field for registering a tag ID (that is, a tag ID of the second IC tag 73B-2) acquired when the card 60SB is placed face up. The "face-down" field is a field for registering a tag ID (that is, a tag ID of the first IC tag 73B-1) acquired when the card 60SB is placed face down.

In step S410B, the control unit 41 adds a new record to the association data D1B, registers the card ID specified in step S402B in the "card ID" field, and stores the tag ID acquired in step S404B in the "face-up" field. And the tag ID acquired in step S408B is registered in the "face down" field.

After executing step S410B, a completion notification indicating that the association process is completed is output, the player removes the card 60SB placed in the zone Z, and the next card 60SB from his / her deck is placed vertically and face up. Place it in the above zone Z. In this state, the association process shown in FIG. 30 is executed again.

By executing the association process shown in FIG. 30 for each card 60SB included in the deck of the first player, information on all the cards 60SB included in the deck of the first player is registered in the association data D1B. For each card 60SB included in the deck of the second player, the information of all the cards 60SB included in the deck of the second player is registered in the association data D1B by executing the association process shown in FIG.

[3-2-2] FIG. 32 shows another example of the association processing of the third embodiment. Instead of the association process shown in FIG. 30, the association process shown in FIG. 32 may be executed.

The association process shown in FIG. 32 is premised on the premise that an IC tag writer for writing information to the first IC tag 73B-1 and the second IC tag 73B-2 is installed under the zone Z. Hereinafter, the reader 20 will be described as an IC tag reader / writer having both functions of an IC tag reader and an IC tag writer.

As shown in FIG. 32, first, the control unit 41 acquires a photographed image of the photographing apparatus 30 (S420B). Then, the control unit 41 identifies the card ID of the card 60SB shown in the captured image from the captured image (S422B). The processing of steps S420B and S422B is the same as that of steps S400 and S402 of FIG.

After executing step S422B, the control unit 41 writes the card ID specified in step S422B and the front and back flags to the second IC tag 73B-2 of the card 60SB placed in the zone Z (S424B).

The front and back flags are information indicating whether the card 60SB is placed face up or face down. For example, the value "0" or "1" is set as the front and back flags. A value "0" indicates that the card 60SB is placed face up, and a value "1" indicates that the card 60SB is placed face down. In step S424B, the value "0" indicating that the face is face up is written as the front and back flags.

The control unit 41 sends a writing instruction of the card ID specified in step S422B and the front and back flags (0) to the reading device 20 (IC tag reader / writer) placed under the zone Z. Then, in response to the writing instruction, the reading device 20 writes the card ID and the front and back flags (0) to the second IC tag 73B-2 of the card 60SB placed in the zone Z. In this case, since the transmission / reception of the signal between the first IC tag 73B-1 and the reading device 20 is hindered by the blocking surface portion 74B (magnetic material or the like), the writing to the first IC tag 73B-1 is performed at this point. I won't get it.

After executing step S424B, the control unit 41 outputs a flipping request notification indicating that the player is requested to flip the card 60SB (S426B). The process of step S426B is the same as that of step S406B of FIG.

In response to the inside-out request notification, the player turns the card 60SB placed face down in the zone Z by turning it over. In this state, the process of step S428B is executed.

That is, the control unit 41 writes the card ID specified in step S422B and the front and back flags to the first IC tag 73B-1 of the card 60SB placed in the zone Z (S428B). In this case, the value "1" indicating that it is face down is written as the front and back flags.

Specifically, the control unit 41 sends a write instruction between the card ID specified in step S422B and the front and back flags (1) to the reader 20 (IC tag reader / writer) placed under the zone Z. send. Then, in response to the writing instruction, the reading device 20 writes the card ID and the front / back flag (1) to the first IC tag 73B-1 of the card 60SB placed in the zone Z. In this case, since the transmission / reception of the signal between the second IC tag 73B-2 and the reading device 20 is hindered by the blocking surface portion 74B (magnetic material or the like), the writing to the second IC tag 73B-2 is not performed at this point. ..

After the execution of step S428B, a completion notification indicating that the association process is completed is output, the first player removes the card 60SB placed in the zone Z, and the next card 60SB from his / her deck is turned vertically and Place it face up in the zone Z. In this state, the association process shown in FIG. 32 is executed again.

By executing the association processing shown in FIG. 32 for each card 60SB included in the deck of the first player, the first IC tag 73B-1 and the second IC tag 73B of each card 60SB included in the deck of the first player are executed. The card ID and the front and back flags are stored in -2. Further, with respect to each card 60SB included in the deck of the second player, the association processing shown in FIG. 32 is executed, so that the first IC tag 73B-1 and the first IC tag 73B-1 of each card 60SB included in the deck of the second player are executed. The card ID and the front and back flags are also stored in the 2IC tag 73B-2.

[3-2-3] Also in the third embodiment, a specific process similar to the specific process shown in FIG. 13 is executed. Here, the specific processing of the third embodiment will be described with reference to FIG. Further, here, it is assumed that the association data D1B shown in FIG. 31 is stored in the storage unit 42.

In the third embodiment, in step S432, the control unit 41 specifies the position and the vertical / horizontal orientation of the card 60SB placed on the game field F, and does not specify the front / back orientation of the card 60SB. In this case, the specific result in step S432 is registered in the first specific result data D2B.

FIG. 33 shows an example of the first specific result data D2B. As shown in FIG. 33, the first specific result data D2B includes "area ID" and "vertical and horizontal flags" fields. The "area ID" and "vertical and horizontal flags" fields are the same as the "area ID" and "vertical and horizontal flags" fields of the first specific result data D2 of the first embodiment.

Further, in the third embodiment, in step S436, the control unit 41 specifies the card ID, the position, and the orientation of the front and back of the card 60SB placed in the game field F.

For example, when the card 60SB is placed face up in the zone Z10, the tag ID stored in the second IC tag 73B-2 is read by the reading device 20-10, and information is used as the reading result data of the reading device 20-10. It is supplied to the processing device 40. In this case, since the transmission / reception of the signal between the first IC tag 73B-1 and the reading device 20-10 is hindered by the blocking surface portion 74B, the tag ID stored in the first IC tag 73B-1 is the reading device 20-. Not read by 10.

The control unit 41 identifies the card ID of the card 60SB and the orientation of the front and back sides based on the tag ID read by the reading device 20-10. The method of specifying the card ID is basically the same as that of step S436 of the first embodiment, except that the association data D1B is referred to instead of the association data D1.

The control unit 41 refers to the association data D1B and determines whether the tag ID read by the reading device 20-10 is registered in the “face-up” or “face-down” field. Then, when the tag ID read by the reading device 20-10 is registered in the "face-up" field, the control unit 41 identifies that the card 60SB is face-up. On the other hand, when the tag ID read by the reader 20-10 is registered in the "face down" field, the control unit 41 identifies that the card 60SB is face down.

In this case, the specific result in step S426 is registered in the second specific result data D3B. FIG. 34 shows an example of the second specific result data D3B. As shown in FIG. 34, the second specific result data D3B includes a "reader ID", a "card ID", and a "front and back flag" field. The "reading device ID" and "card ID" fields are the same as the "reading device ID" and "card ID" fields of the second specific result data D3 of the first embodiment, and the "front and back flag" fields of the first embodiment. It is the same as the "front and back flag" field of the first specific result data D2.

For example, when the tag ID is read by the reading device 20-10, the control unit 41 sets the card ID and the front / back orientation specified from the tag ID as the "card ID" of the record of the reading device ID "R10" and the "card ID". Register in the "Front and back flags" field.

In the above description, the case where the association data D1B shown in FIG. 31 is stored in the storage unit 42 by the association processing shown in FIG. 30 has been described, but the card ID and the front and back sides are described by the association processing shown in FIG. When the flag is stored in the first IC tag 73B-1 and the second IC tag 73B-2 of the card 60SB, the card ID and the front and back flags are read by the reading device 20-10. Therefore, in step S436, the control unit 41 Registers the card ID and the front and back flags read by the reader 20-10 in the "card ID" and "front and back flags" fields of the record of the reader ID "R10".

Further, in the third embodiment, in step S438, the control unit 41 generates the game field status data D4 based on the first specific result data D2B and the second specific result data D3B. The game field status data D4 is the same as that of the first embodiment. Further, the process of step S438 in this case is the first except that the front and back flags registered in the "front and back flags" field of the second specific result data D3B are registered in the "front and back flags" field of the game field status data D4. It is the same as step S438 of one embodiment.

In the situation shown in FIG. 7, a bundle of cards 600-1 (that is, a plurality of cards 60SB stacked face down) is placed in the zone Z7, but in the third embodiment, the blocking surface portion 74B is placed. By the presence of, only the ID tag stored in the first IC tag 73B-1 of the bottom card 60SB in the card bundle 600-1 is read. As a result, in the "card ID" field of the record of the reader ID "R7" of the second specific result data D3B and the record of the zone ID "Z7" of the game field status data D4, a bundle of cards placed in the zone Z7 Only the card ID of the bottom card 60SB out of 600-1 is registered. The same applies to zones Z1, Z15, and Z21.

[3-2-4] Also in the third embodiment, the display control process shown in FIG. 18 and the process shown in FIG. 19 are executed. However, in the parts PA-1 to PA-4 of the game field image G of the third embodiment, the numerical value indicating the number of cards 60SB included in the card bundle 600-1 to 600-4 is not displayed.

[3-3. Effect] According to the third embodiment, the orientation of the front and back of the card 60SB placed in the game field F can be specified based on the reading result of the reading device 20.

In the third embodiment, when the card 60SB is placed face up, the information stored in the first IC tag 73B-1 is secured so as not to be read by the reading device 20, and the card 60SB is on the back side. When placed in the orientation, it is necessary to ensure that the information stored in the second IC tag 73B-2 is not read by the reading device 20.

For example, when the card 60SB is placed face up, the distance between the first IC tag 73B-1 and the reading device 20 becomes large (that is, the information stored in the first IC tag 73B-1 is stored by the reading device 20). The distance between the second IC tag 73B-2 and the reading device 20 when the card 60SB is placed face down is also increased (that is, stored in the second IC tag 73B-2). If the information is so large that it cannot be read by the reading device 20, it is not necessary to take any special measures for the above-mentioned collateral. However, since the card 60 and the sleeve 70 are thin and the above distance does not increase, it is necessary to take measures for the above collateral. In this respect, in the third embodiment, the above-mentioned collateral is realized by providing the blocking surface portion 74B in the sleeve 70B.

[3-4. Modification example] A modification of the third embodiment will be described.

[3-4-1] In the embodiment described above, the second IC tag 73B-2 is installed on the second surface 76B of the blocking surface portion 74B, but the second IC tag 73B-2 is installed on the back surface portion 72B of the sleeve 70B. It may be installed on the inner surface of the.

[3-4-2] In the embodiment described above, the cutoff surface portion 74B is fixed to the sleeve 70B, but the cutoff surface portion 74B is attached to the sleeve 70B together with the card 60, for example, the object 80 shown in FIG. It may be a sheet-like object housed inside.

[3-4-3] In the embodiment described above, the blocking surface portion 74B is formed of a magnetic material, but the blocking surface portion 74B may be formed of a material other than the magnetic material. It prevents the transmission and reception of the signal between the first IC tag 73B-1 and the reading device 20 via the back surface portion 72B of the sleeve 70B, or prevents the transmission and reception of the signal between the second IC tag 73B-2 and the reading device 20. Any material that can prevent transmission and reception from being transmitted via the surface portion 71A of the sleeve 70B can be used as a material for the blocking surface portion 74B.

[3-4-4] Also in the third embodiment, in step S422, the control unit 41 may specify the front and back orientation of the card 60SB. That is, the control unit 41 may specify the front and back orientation of the card 60SB from the captured image of the photographing device 30, and may also specify the front and back orientation of the card 60SB from the reading result of the reading device 20. In this case, by collating the front / back orientation specific result obtained from the captured image of the photographing device 30 with the front / back orientation specifying result obtained from the reading result of the reading device 20, the front / back orientation specifying result is obtained. You may try to improve the accuracy of.

[3-5. Functional elements] FIG. 35 is a functional block diagram for explaining the functional elements included in the system 1B according to the third embodiment. In FIG. 35, the functional elements that are the same as the functional elements of the first embodiment (shooting unit 110, captured image acquisition unit 120, reading unit 130, reading result acquisition unit 140, display control unit 160, and display unit 170). 22 is designated by the same reference numerals as those in FIG. 22, and the description of these functional elements is omitted here, and the object 100B and the specific portion 150B will be described. Further, regarding the explanation of the wording, the explanation will be omitted with respect to the point overlapping with the first embodiment.

[3-5-1] First, the object 100B will be described. Here, the difference between the object 100B and the object 100 in the first embodiment will be described.

The object 100B includes a first surface portion and a second surface portion. These first surface portions and second surface portions are the same as the first surface portions and the second surface portions described as being included in the object 100 of the first embodiment.

Further, the object 100B includes a first holding portion 101B and a second holding portion 102B. The first holding unit 101B and the second holding unit 102B hold specific information for specifying the type and state of the object 100B placed on the target surface. The specific information in this case includes information that is the basis for specifying the type of the object 100B and information that is the basis for specifying the state of the object 100B. When the object 100B is an object in which the game medium is housed in the housing, the information that is the basis for identifying the type or state of the game medium placed on the target surface in the state of being housed in the housing. Corresponds to "information that is the basis for specifying the type or state of the object 100B".

The information held in the first holding unit 101B and the second holding unit 102B is read by the reading unit 130. In order to distinguish whether the information read by the reading unit 130 is the information held by the first holding unit 101B or the second holding unit 102B, the first holding unit 101B and the second holding unit 102B The information held in each of the above contains different information. For example, the identification information of the first holding unit 101B is held in the first holding unit 101B, and the identification information of the second holding unit 102B is held in the second holding unit 102B. In the third embodiment, the front and back orientations of the object 100B are specified based on the different information held in each of the first holding unit 101B and the second holding unit 102B, so that the different information is "object". It corresponds to "the basic information for specifying the state of 100B".

Further, the object 100B includes the limiting unit 103B. The limiting unit 103B restricts the reading of the information held by the first holding unit 101B by the reading unit 130 via the second surface portion of the object 100B, and the reading unit 130 restricts the reading of the information held by the first holding unit 101B to the second holding unit 102B. It limits that the reading of the information held in the object 100B is performed through the first surface portion of the object 100B.

For example, the first holding unit 101B is a first IC tag installed so as to communicate with the reading unit 130 (IC tag reader) via the first surface portion of the object 100B. In other words, the first holding unit 101B is a first IC tag restricted from communicating with the reading unit 130 (IC tag reader) via the second surface portion of the object 100B.

Further, the second holding unit 102B is a second IC tag installed so as to communicate with the reading unit 130 (IC tag reader) via the second surface portion of the object 100B. In other words, the second holding unit 102B is a second IC tag restricted from communicating with the reading unit 130 (IC tag reader) via the first surface portion of the object 100B.

The first IC tag is installed so as to face the first surface portion of the object 100B. Alternatively, the first IC tag is installed on the inner surface of the first surface portion of the object 100B. Further, the first IC tag is installed closer to the first surface portion of the object 100B than the second IC tag. Further, the second IC tag is installed so as to face the second surface portion of the object 100B. Alternatively, the second IC tag is installed on the inner surface of the second surface portion of the object 100B. Further, the second IC tag is installed closer to the second surface portion of the object 100B than the first IC tag.

The first IC tag is arranged between the first surface portion of the object 100B and the limiting portion 103B, and the second IC tag is arranged between the second surface portion of the object 100B and the limiting portion 103B. The limiting unit 103B limits that communication between the reading device 20 for reading the information held in the first IC tag or the second IC tag and the first IC tag is performed via the second surface portion of the object 100B. , The communication between the reading device 20 and the second IC tag is restricted to be performed via the first surface portion of the object 100B.

For example, the limiting portion 103B includes a magnetic material provided between the first IC tag and the second surface portion of the object 100B. Further, the limiting portion 103B includes a magnetic material provided between the second IC tag and the first surface portion of the object 100B. In other words, the limiting unit 103B includes a magnetic material provided between the first IC tag and the second IC tag. The signal (radio wave) from the first IC tag is blocked from being transmitted through the second surface portion of the object 100B, and the signal (radio wave) from the second IC tag is transmitted via the first surface portion of the object 100B. Anything that can block what is done can be adopted as the limiting unit 103B.

[3-5-2] The specific unit 150B will be described. The specific unit 150B includes a first specific unit 151B and a second specific unit 152B.

The first specifying unit 151B identifies the position and orientation of the object 100B based on the captured image of the photographing device 30. For example, the first specific unit 151B specifies the position and the vertical / horizontal orientation of the object 100B in the same manner as the first specific unit 151 of the first embodiment.

The second specifying unit 152B specifies the position, type, and orientation of the object 100B based on the reading result of the reading device 20. The second specific unit 152B specifies the position and type of the object 100B in the same manner as the second specific unit 152 of the first embodiment.

The second specifying unit 152B also specifies the orientation of the front and back of the object 100B. That is, the second specific unit 152B is the object 100B based on the reading result of the information stored in the first holding unit 101B (first IC tag) or the second holding unit 102B (second IC tag) by the reading device 20. It is specified whether the object 100B is placed on the target surface so that either the first surface portion or the second surface portion faces the target surface.

For example, when the information stored in the first holding unit 101B (first IC tag) is read by the reading unit 130, in the second specific unit 152B, the first surface portion of the object 100B is directed toward the reading unit 130. Judge that it is suitable. For example, when the reading unit 130 is installed below the target surface, the second specific unit 152B determines that the first surface portion of the object 100B faces the target surface. If the reading unit 130 is installed above the target surface, the second specific unit 152B determines that the second surface portion of the object 100B faces the target surface.

On the other hand, when the information stored in the second holding unit 102B (second IC tag) is read by the reading unit 130, in the second specific unit 152B, the second surface portion of the object 100B is directed toward the reading unit 130. Judge that it is suitable. For example, when the reading unit 130 is installed below the target surface, the second specific unit 152B determines that the second surface portion of the object 100B faces the target surface. If the reading unit 130 is installed above the target surface, the second specific unit 152B determines that the first surface portion of the object 100B faces the target surface.

[3-5-3] In the case of the above-mentioned example of the card game, the card 60SB corresponds to an example of the object 100B. Further, the front surface portion 71B and the back surface portion 72B of the sleeve 70B correspond to an example of the "first surface portion" and the "second surface portion", respectively. Further, the first IC tag 73B-1 and the second IC tag 73A-2 of the sleeve 70B correspond to an example of the first holding portion 101B (first IC tag) and the second holding portion 102B (second IC tag), respectively. Further, the blocking surface portion 74B of the sleeve 70B corresponds to an example of the limiting portion 103B.

For example, when the information stored in the first IC tag 73B-1 of the card 60SB is read by the reading device 20, the second specifying unit 152B identifies that the card 60SB is placed face down. On the other hand, when the information stored in the second IC tag 73B-2 of the card 60SB is read by the reading device 20, the second specifying unit 152B identifies that the card 60SB is placed face up.

[4. Fourth Embodiment] The fourth embodiment of the present invention will be described.

The fourth embodiment differs from the first embodiment in that the type or state of the card is specified by reading the code printed on the sleeve with invisible ink. Hereinafter, the differences from the first embodiment will be described. In the following, the same reference numerals will be used for the same elements as those of the first embodiment, and the description thereof will be omitted.

[4-1. Overview] FIG. 36 shows the configuration of the system 1C according to the fourth embodiment. As shown in FIG. 36, the system 1C includes a game board 10C, a first photographing device 30C-1, a second photographing device 30C-2, an information processing device 40, and a display terminal device 50. The information processing device 40 and the display terminal device 50 are the same as those in the first embodiment.

The game board 10C is basically the same as the game board 10 of the first embodiment except that the reading device 20 (IC tag reader) is not included.

The first photographing device 30C-1 corresponds to the photographing device 30 of the first embodiment, and is a visible light camera. On the other hand, the second photographing device 30C-2 is an invisible light camera (for example, an infrared camera or the like). The second photographing apparatus 30C-2 is used to read the code printed with the invisible ink. The "invisible ink" is an ink (for example, infrared ink) that can be recognized by an image sensor by irradiating with invisible light (for example, infrared light).

FIG. 37 is a diagram for explaining an example of the sleeve 70C of the fourth embodiment. Similar to the sleeve 70 of the first embodiment, the surface portion 71C of the sleeve 70C is transparent so that the surface 61 of the card 60 housed in the sleeve 70C can be visually recognized from the outside of the sleeve 70C. Further, as in the sleeve 70 of the first embodiment, the back surface portion 72C of the sleeve 70C is opaque, and the appearance of the back surface portion 72C visible to humans is the same for all sleeves 70C.

The surface portion 71C of the sleeve 70C includes the first code 77C-1. The first code 77C-1 is printed on the outer surface of the surface portion 71C with invisible ink. In FIG. 37, the first code 77C-1 is printed in the center of the surface portion 71C, but the first code 77C-1 may be printed in a position other than the center. The first code 77C-1 is a code in which the sleeve ID of the sleeve 70C is embedded. That is, the first code 77C-1 is a coded version of the sleeve ID of the sleeve 70C according to a predetermined standard (rule). In other words, the first code 77C-1 is a code including a pattern generated based on the sleeve ID of the sleeve 70C (a pattern unique to the sleeve ID). The first code 77C-1 is, for example, a two-dimensional code (QR code (registered trademark), etc.). The sleeve ID is information that uniquely identifies each sleeve 70C.

Further, the back surface portion 72C of the sleeve 70C includes the second code 77C-2. The second code 77C-2 is printed with invisible ink on the outer surface of the back surface portion 72C. Like the first code 77C-1, the second code 77C-2 is also a code in which the sleeve ID of the sleeve 70C is embedded. That is, the sleeve ID of the sleeve 70C is embedded in both the first code 77C-1 and the second code 77C-2.

In the following, the first code 77C-1 and the second code 77C-2 may be collectively referred to as "code 77C". Further, in the following, the card 60 in the state of being housed in the sleeve 70C will be referred to as “card 60SC” for convenience in order to distinguish it from the card 60 alone. In other words, when the card 60 is housed in the sleeve 70C, the card 60 and the sleeve 70C are regarded as one object and are described as "card 60SC".

Like the first photographing device 30C-1, the second photographing device 30C-2 is also fixed above the game field F. The captured image of the second imaging device 30C-2 also includes at least zones Z1 to Z30 of the game field F.

For example, the second photographing device 30C-2 captures an electronic image by capturing an image of a light source that irradiates the game field F with invisible light and the reflected light reflected by the game field F or the card 60SC placed in the game field F. Includes an image sensor that converts to a signal and outputs it. It should be noted that the reflected light from which visible light (disturbed light) has been removed is input to the image sensor. The second photographing device 30C-2 is used to read the first code 77C-1 or the second code 77C-2 of the card 60SC placed in the game field F.

The second photographing apparatus 30C-2 and the information processing apparatus 40 are connected via a cable conforming to a predetermined interface standard. Alternatively, the second photographing device 30C-2 and the information processing device 40 can communicate with each other via a communication network. The second photographing device 30C-2 photographs the game field F at predetermined time intervals, and the captured image is supplied to the information processing apparatus 40 via the cable or the communication network.

When the game field F is placed face up on the card 60SC, the captured image of the second imaging device 30C-2 includes the first code 77C-1 of the surface portion 71C of the card 60SC, and is based on the captured image. Then, the information (sleeve ID) embedded in the first code 77C-1 is acquired. On the other hand, when the game field F is placed with the card 60SC face down, the captured image of the second imaging device 30C-2 includes the second code 77C-2 of the back surface 72C of the card 60SC, and the captured image is taken. The information (sleeve ID) embedded in the second code 77C-2 is acquired based on the image.

[4-2. Process] A process executed by the system 1C according to the fourth embodiment will be described.

[4-2-1] FIG. 38 shows an example of the association processing of the fourth embodiment. For example, the player places one card 60SC from his or her deck in a predetermined zone Z (for example, zone Z11, etc.) in the game field F in portrait and face up directions. In this state, the association process shown in FIG. 38 is executed.

As shown in FIG. 38, first, the control unit 41 of the information processing apparatus 40 acquires a captured image of the first imaging device 30C-1 (S400C). Then, the control unit 41 identifies the card ID of the card 60SC shown in the captured image from the captured image (S402C). Steps S400C and S402C are the same as steps S400 and S402 in FIG.

Further, the control unit 41 acquires a photographed image of the second photographing apparatus 30C-2 (S404C). Then, the control unit 41 acquires the sleeve ID from the first code 72C-1 shown in the captured image (S406C). Then, the control unit 41 registers the association between the card ID specified in step S402C and the sleeve ID acquired in step S406C in the association data D1C (S408C).

FIG. 39 shows an example of the association data D1C in the fourth embodiment. As shown in FIG. 39, the association data D1C includes "card ID" and "sleeve ID" fields. The "card ID" field is the same as the "card ID" field of the association data D1 of the first embodiment. The "sleeve ID" field is a field for registering the sleeve ID.

In step S408C, the control unit 41 adds a new record to the association data D1C, and acquires the card ID specified in step S402C and the card ID in step S406C for the "card ID" and "sleeve ID" fields of the record. Register the sleeve ID that has been created.

After the execution of step S408C, a completion notification indicating that the association process is completed is output, the player removes the card 60SC placed in the zone Z, and the next card 60SC from his / her deck is placed vertically and face up. Place it in the above zone Z. In this state, the association process shown in FIG. 38 is executed again.

By executing the association process shown in FIG. 38 for each card 60SC included in the deck of the first player, information on all the cards 60SC included in the deck of the first player is registered in the association data D1C. Further, for each card 60SC included in the deck of the second player, the information of all the cards 60SC included in the deck of the second player is registered in the association data D1C by executing the association process shown in FIG. 38. ..

[4-2-2] FIG. 40 shows an example of the specific processing of the fourth embodiment. As shown in FIG. 40, first, the control unit 41 of the information processing apparatus 40 acquires a captured image of the first imaging device 30C-1 (S430C). Then, the control unit 41 specifies the position and orientation of the card 60SC from the captured image (S432C). The processing of steps S430C and S432C is the same as that of steps S430 and S432 of FIG. The specific result in step S432C is registered in the first specific result data D2. The first specific result data D2 is the same as that of the first embodiment.

After the execution of step S432C, the control unit 41 acquires the captured image of the second imaging device 30C-2 (S434C), and the control unit 41 identifies the position of the card 60SC and the card ID from the captured image (S436C).

For example, the control unit 41 determines whether or not the code 77C (first code 77C-1 or second code 77C-2) is captured in each of the areas A1 to A30 of the captured image. Further, the control unit 41 acquires the sleeve ID from the code 77C in the image.

The specific result in step S436C is registered in the second specific result data D3C. FIG. 41 shows an example of the second specific result data D3C. As shown in FIG. 41, the second specific result data D3C includes "area ID" and "card ID" fields. The "region ID" field is the same as the "region ID" field of the first specific result data D2 of the first embodiment, and the "card ID" field is the "card ID" of the second specific result data D3 of the first embodiment. Similar to the field.

For example, when the code 77C is shown in the area A10, the control unit 41 registers the sleeve ID acquired from the code 77C in the "card ID" field of the record of the area ID "A10".

After executing step S436C, the control unit 41 generates game field status data D4 based on the first specific result data D2 and the second specific result data D3C (S438C). The game field status data D4 is the same as that of the first embodiment.

In the situation shown in FIG. 7, the card bundle 600-1 (that is, a plurality of cards 60SC stacked face down) is placed in the zone Z7, but in the fourth embodiment, the card bundle 600-1 (that is, a plurality of cards 60SC stacked face down) is placed in the zone Z7. Only the second code 77C-2 of the top card 60SC in the card bundle 600-1 that has been drawn appears in the photographed image of the second photographing apparatus 30C-2. Therefore, in the "card ID" field of the record of the area ID "A7" of the second specific result data D3C and the record of the zone ID "Z7" of the game field status data D4, the card bundle 600 placed in the zone Z7 Only the card ID of the top card 60SC of -1 is registered. The same applies to zones Z1, Z15, and Z21.

[4-2-3] Also in the fourth embodiment, the display control process shown in FIG. 18 and the process shown in FIG. 19 are executed. However, in the parts PA-1 to PA-4 of the game field image G of the fourth embodiment, the numerical value indicating the number of cards 60SC included in the card bundle 600-1 to 600-4 is not displayed.

[4-3. Effect] According to the fourth embodiment, when the card 60SC is placed face up on the game field F, the first code 77C-1 of the surface portion 71C of the card 60SC is photographed by the second photographing device 30C-2. As a result, the information embedded in the first code 77C-1 can be read, and as a result, the card ID of the card 60SC can be acquired. On the other hand, when the card 60SC is placed face down on the game field F, the second code 77C-2 of the back surface portion 72C of the card 60SC is photographed by the second photographing device 30C-2, so that the second code is photographed. The information embedded in the 77C-2 can be read, and as a result, the card ID of the card 60SC can be obtained. As described above, according to the fourth embodiment, the card ID of the card 60SC can be acquired regardless of whether the card 60SC is placed face up or face down.

According to the fourth embodiment, even when the card 60SC is placed face down on the game field F (that is, when the card 60SC is placed on the game field F with the surface 61 invisible). Based on the information held in the second code 77C-2 of the back surface portion 72C of the card 60SC, the information written on the front surface 61 of the card 60 (name, performance, etc. of the card 60) can be specified.

Further, according to the fourth embodiment, since the code 77C is printed on the sleeve 70C, even if the code 77C is not printed on the card 60 itself, the card 60 can be stored in the sleeve 70C and used. , The type and state of the card 60 can be specified based on the captured image of the second imaging device 30C-2. That is, since the code 77C does not need to be printed on the card 60 itself, for example, an existing card 60 on which the code 77C is not printed can be used.

Further, according to the fourth embodiment, since the code 77C is printed in an invisible state that cannot be visually recognized by a human, it is possible to prevent the appearance of the card 60SC (card 60) as seen by a human from being impaired. Also, when the card 60SC is placed face down on the game field F, the opponent relies on the second code 77C-2 printed on the back side 72C, and the name and performance of the card 60 that should not be grasped originally. It is also possible to try not to be able to grasp such things.

[4-4. Modification example] A modification of the fourth embodiment will be described.

[4-4-1] For example, in the first code 77C-1, information indicating that the code is printed on the surface portion 71C may be embedded together with the sleeve ID. Further, in the second code 77C-2, information indicating that the code is printed on the back surface portion 72C may be embedded together with the sleeve ID.

Specifically, "0" indicating that the front and back flags are embedded in the first code 77C-1 together with the sleeve ID, and as the front and back flags together with the sleeve ID in the second code 77C-2. , "1" indicating that it is the back may be embedded. Then, the front and back flags may be acquired together with the sleeve ID from the code 77C shown in the captured image of the second imaging device 30C-2.

By doing so, when the card 60SC is placed face up, it is specified that the card 60SC is placed face up by acquiring "0" as the front and back flags from the first code 77C-1. When the card 60SC is placed face down, it can be specified that the card 60SC is placed face down by acquiring "1" as a front / back flag from the second code 77C-2. That is, the orientation of the front and back of the card 60SC can be specified based on the captured image of the second imaging device 30C-2. That is, the state of the card 60SC can be specified based on the captured image of the second imaging device 30C-2.

[4-4-2] For example, similarly to the first IC tag 73-1 and the second IC tag 73C-2 of the second embodiment, even if a plurality of codes 77C having a predetermined positional relationship are printed on the back surface portion 72C. good. Then, when the card 60SC is placed face down, the vertical and horizontal orientation of the card 60SC is specified based on the positional relationship of these plurality of codes 77Cs reflected in the captured image of the second photographing device 30C-2. You may.

Further, a plurality of codes 77C having a predetermined positional relationship may be printed on the surface portion 71C. Then, when the card 60SC is placed face up, the vertical and horizontal orientations of the card 60SC are specified based on the positional relationship of these plurality of codes 77Cs reflected in the captured image of the second photographing device 30C-2. May be good.

By doing so, the vertical and horizontal orientation of the card 60SC can be specified based on the captured image of the second imaging device 30C-2.

[4-4-3] Further, for example, the card ID of the card 60 may be embedded with the first code 77C-1 and the second code 77C-2.

[4-5. Functional elements] FIG. 42 is a functional block diagram for explaining the functional elements included in the system 1C according to the fourth embodiment. In FIG. 42, the same functional elements (display control unit 160 and display unit 170) as those in the first embodiment are designated by the same reference numerals as those in FIG. 22, and the description of these functional elements will be described here. Omit. Further, regarding the explanation of the wording, the explanation will be omitted with respect to the point overlapping with the first embodiment.

[4-5-1] First, the object 100C will be described. The object 100C is an object in which the game medium is housed in the housing.

The game medium has a surface having an appearance according to the type of the game medium (hereinafter, referred to as a "characteristic surface" for convenience). For example, a characteristic surface is a surface having an appearance peculiar to the type of amusement medium. Further, for example, the characteristic surface is a surface on which a text or a pattern corresponding to the type of the game medium is written.

The containment includes a first surface portion and a second surface portion. These first surface portions and second surface portions are the same as those of the first surface portion and the second surface portion described as being included in the housing (object 100) in the first embodiment. When the game medium is housed in the housing, the first surface portion (inner side surface of the first surface portion) and the characteristic surface of the game object face each other. For example, all or part of the first surface portion is formed by using a transparent material (transparent film or the like), and the first surface portion is a first surface portion of a game object housed in the housing from outside the housing. It is configured to be visible through the face portion.

The object 100C includes a first holding portion 101C and a second holding portion 102C. The first holding portion 101C is provided on the first surface portion of the accommodating body. The first holding unit 101C is for holding the first specific information for specifying the type or state of the game medium housed in the container.

For example, the first specific information is written on the first surface portion of the object 100C (accommodation body) in an invisible state that is not visible to humans. In this case, the portion in which the first specific information is written in an invisible state corresponds to the first holding portion 101C. For example, the first specific information is written on the first surface using invisible ink. In addition, for example, the first specific information is written on the outer surface of the first surface portion.

The "first specific information" is information that is the basis for specifying at least one of the type and state of the game medium contained in the container. In other words, the "first specific information" is the information that is the basis for specifying the type of the game medium housed in the containment body and the basis for specifying the state of the game medium housed in the containment body. Includes at least one with information.

For example, there is data relating the accommodation ID that uniquely identifies the accommodation and the game medium ID of the game medium accommodated in the accommodation, and the game accommodated in the accommodation is based on the accommodation ID. When the type of the medium can be specified, the "first specific information" includes the accommodation ID as "the basic information for specifying the type of the game medium accommodated in the accommodation". Further, for example, the "first specific information" may include a game medium ID that uniquely identifies the type of the game medium.

Further, for example, the "first specific information" may include the first identification information that identifies the first holding unit 101C as "information that is the basis for specifying the state of the game medium accommodated in the container". For example, when the first identification information stored in the first holding portion 101C of the first surface portion is read, the object 100C is placed on the target surface so that the second surface portion and the target surface are in contact with each other. Is identified. Therefore, the "first specific information" refers to the first identification information that identifies the first holding portion 101C as the "arrangement format of the object 100C (the object 100C is targeted so that the second surface portion and the target surface are in contact with each other). It may be included as "information that is the basis for identifying (whether or not it is placed on a surface)".

On the other hand, the second holding portion 102C is provided on the second surface portion of the accommodating body. The second holding unit 102C is for holding the second specific information for specifying the type or state of the game medium housed in the container.

For example, the second specific information is written on the second surface portion of the object 100C (accommodation body) in an invisible state that is not visible to humans. In this case, the portion in which the second specific information is written in an invisible state corresponds to the second holding portion 102C. For example, the second specific information is written on the second surface using invisible ink. In addition, for example, the second specific information is written on the outer surface of the second surface portion.

Similar to the first specific information, the "second specific information" is information that is the basis for specifying at least one of the type and state of the game medium accommodated in the container.

For example, the "second specific information" is a basis for specifying the accommodation ID of the accommodation or the game medium ID of the game medium accommodated in the accommodation as "the type of the game medium accommodated in the accommodation". Information is included.

Further, for example, the "second specific information" may include the second identification information that identifies the second holding unit 102C as "information that is the basis for specifying the state of the object 100C". For example, when the second identification information stored in the second holding portion 102C of the second surface portion is read, the object 100C is placed on the target surface so that the first surface portion and the target surface are in contact with each other. Is identified. Therefore, the "second specific information" refers to the second identification information that identifies the second holding portion 102C as the "arrangement format of the object 100C (the object 100C is targeted so that the first surface portion and the target surface are in contact with each other). It may be included as "information that is the basis for identifying (whether or not it is placed on a surface)".

When each of the first specific information and the second specific information includes only "information that is the basis for specifying the type of the game medium accommodated in the container", the first specific information and the second specific information are It will be the same information.

The first surface portion and the second surface portion of the accommodating body are the second holding portion 102C of the second surface portion when the object 100C is placed on the target surface so that the outer surface of the first surface portion and the target surface are in contact with each other. When the object 100C is placed on the target surface so that the outer surface of the second surface portion and the target surface are in contact with each other, the second specific information held in the second specific information can be read by the reading unit 130C. It has a positional relationship so that the first specific information held by the first holding portion 101C of the first surface portion can be read by the reading unit 130C.

For example, when the object 100C is placed on the target surface so that the outer surface of the first surface and the target surface are in contact with each other, the first surface portion and the second surface portion of the accommodation body are the outer surfaces of the second surface portion. Is facing upward, and it becomes possible to read the second specific information held by the second holding portion 102C of the second surface portion via the device installed above the target surface, and the outside of the second surface portion. When the object 100C is placed on the object surface so that the side surface and the object surface are in contact with each other, the outer surface of the first surface portion faces upward, and the device installed above the object surface is used. It has a positional relationship so that the first specific information held by the first holding portion 101C of the first surface portion can be read.

In the case of the above-mentioned card game example, the card 60SC corresponds to an example of the object 100C, the card 60 corresponds to an example of the "game medium", and the sleeve 70C corresponds to an example of the "accommodator". Further, the front surface portion 71C and the back surface portion 72C of the sleeve 70C correspond to an example of the "first surface portion" and the "second surface portion".

Further, the first code 77C-1 and the second code 77C-2 correspond to an example of the first holding unit 101C and the second holding unit 102C. Further, the sleeve ID corresponds to an example of "first specific information" and "second specific information". Further, in the case of a modification in which the front and back flags are embedded in each of the first code 77C-1 and the second code 77C-2, the front and back flags also correspond to one example of "first specific information" and "second specific information". ..

[4-5-2] The first photographing unit 110C is realized by the first photographing apparatus 30C-1. The first photographing unit 110C photographs the target surface on which the object 100C is placed. For example, the first photographing unit 110C photographs the target surface from above the target surface. The first photographing unit 110C may be capable of photographing the entire target surface, or may be capable of photographing only the area of the target surface on which the object 100C may be placed. The first captured image acquisition unit 120C acquires the captured image of the first imaging unit 110C.

[4-5-3] The second photographing unit 180C is realized by the second photographing apparatus 30C-2. The second photographing unit 180C photographs the target surface on which the object 100C is placed. The second photographing unit 180C captures an image of the light source that irradiates the target surface with invisible light and the reflected light (invisible light) reflected by the target surface or the object 100C placed on the target surface and converts it into an electronic image signal. Includes an image sensor that converts and outputs. For example, the second photographing unit 180C photographs the target surface from above the target surface. The second photographing unit 180C may be capable of photographing the entire target surface, or may be capable of photographing only the area of the target surface on which the object 100C may be placed. The second captured image acquisition unit 190C acquires the captured image of the second captured image unit 180C.

[4-5-4] The reading unit 130C reads the first specific information held by the first holding unit 101C. The reading unit 130C reads the first specific information based on the captured image of the second photographing unit 180C. Further, the reading unit 130C reads the second specific information held by the second holding unit 102C. The reading unit 130C reads the second specific information based on the captured image of the second photographing unit 180C.

When the object 100C is placed on the target surface, it is held by the second holding portion 102C of the second surface portion of the object 100C so that the first surface portion of the object 100C (accommodation body) is in contact with the target surface. The second specific information can be read by the reading unit 130C. On the other hand, when the object 100C is placed on the object surface so that the second surface portion of the object 100C (accommodation body) is in contact with the object surface, the first holding portion 101C of the first surface portion of the object 100C is used. The retained first specific information can be read by the reading unit 130C.

In the above-mentioned example of the card game, when the card 60SC is placed face up, the first code 77C-1 is captured in the captured image of the second photographing device 30C-2, so that the reading unit 130C has the first code 77C-1. Read the sleeve ID (or front and back flags) embedded in. On the other hand, when the card 60SC is placed face down, the second code 77C-2 is captured in the captured image of the second photographing device 30C-2, so that the reading unit 130C is a sleeve embedded in the second code 77C-2. Read the ID (or front and back flags).

[4-5-5] The specifying unit 150C specifies the position and state of the object 100C based on the captured image of the first photographing unit 110C and the reading result of the reading unit 130C. The specific unit 150C includes a first specific unit 151C and a second specific unit 152C.

For example, the first specifying unit 151C specifies the position and orientation of the object 100C based on the captured image of the first photographing unit 110C. Further, the second specifying unit 152C specifies the position and type of the object 100C based on the reading result of the reading unit 130C. The second specifying unit 152C may specify the position, type, and orientation of the object 100C based on the reading result of the reading unit 130C.

In the case of the above-mentioned example of the card game, the first specifying unit 151C specifies the position, the vertical / horizontal orientation, and the front / back orientation of the card 60SC based on the captured image of the first photographing unit 110C. Further, the second specifying unit 152C specifies the position of the card 60SC and the card ID based on the reading result of the reading unit 130C.

[4-5-6] The second surface portion of the object 100C (accommodation body) may include a third holding portion provided so as to have a predetermined positional relationship with the second holding portion 102C.

That is, as in the modification described above, a plurality of codes 77C may be printed on the back surface portion 72C as well as the first IC tag 73A-1 and the second IC tag 73A-2 of the second embodiment. That is, the back surface portion 72C may include a third code (an example of a third holding portion) having a predetermined positional relationship with the second code 77C-2, in addition to the second code 77C-2.

In this case, similarly to the first IC tag 73A-1 and the second IC tag 73A-2 of the second embodiment, the positions of the second code 77C-2 and the third code are different on the outer surface of the back surface portion 72C. Is placed. The second code 77C-2 and the third code are such that the orientation of the card 60SC can be specified from the positional relationship between the second code 77C-2 and the third code when the card 60SC is placed face up on the game field. Placed in position.

In this way, when the card 60SC is placed face down, the vertical and horizontal orientation of the card 60SC can be specified based on the positional relationship between the second code 77C-2 and the third code. The same applies to the surface portion 71C.

[5. Modifications] The present invention is not limited to the first to fourth embodiments described above.

[5-1] For example, the second embodiment and the third embodiment may be combined. That is, one sleeve may be provided with an IC tag for specifying the vertical and horizontal orientations in addition to the IC tag for specifying the front and back orientations. For example, one sleeve may be equipped with three or four or more IC tags. In this case, the photographing device 30 is not always necessary to specify the position and state (position, vertical / horizontal orientation, front / back orientation) of the card 60.

For example, as in the sleeve 70A shown in FIG. 23, a first IC tag and a second IC tag corresponding to the first IC tag 73A-1 and the second IC tag 73A-2 are provided on the inner surface of the back surface portion of the sleeve, and further, FIG. A cutoff surface portion corresponding to only the lower half of the cutoff surface portion 74B shown in FIG. 29 is also provided in the sleeve, and the surface of the cutoff surface portion corresponding to the first surface 75B shown in FIG. 29 is shown in FIG. 29.
