DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0017]
FIG. 1 is a diagram showing an overall configuration of a game system (image distribution system) 10 according to an embodiment of the present invention. A game system 10 shown in FIG. 1 includes a mobile phone (terminal) 12, a mobile phone base station 14, a data communication network 16, and a game data distribution device (image distribution device) 18. The game data distribution device 18 includes a game server 20 and a game database (DB) 22.
[0018]
The cellular phone 12 includes a display 24 configured using an LCD or the like, a direction key 26, a function button 28, and a round button group 29. The cellular phone 12 is conventionally known, and dial input is possible with the round button group 29, and a telephone book and various setting menus are displayed on the display 24. Various settings are made with the direction keys 26 and the function buttons 28.
[0019]
The cellular phone 12 includes a computer having a CPU and a memory, and has a function of connecting to a data communication network 16 such as the Internet via the cellular phone base station 14. The cellular phone 12 accesses the game server 20 using this network connection function. Then, the mobile phone 12 downloads the game program stored in the game database 22 from the game server 20. The downloaded game program can be stored in the mobile phone 12. In addition, the game program may be stored in the mobile phone 12 in advance. In such a case, the user of the mobile phone 12 does not need to download the game program from the game server 20 (again).
[0020]
The game program downloaded in this way realizes a game in which a conversation with a game character is advanced by selecting one of dialogues (words) displayed for guidance. In this game, the degree of compatibility with the game character changes according to the dialogue selected by the user, a game event occurs, or a game story progresses. A game screen is displayed on the display 24 of the mobile phone 12 in accordance with a user operation, occurrence of a predetermined game event, progress of a game, or the like. The game screen is displayed based on image data acquired by transmitting data indicating a distribution request (download request) to the game server 20, image data stored in the mobile phone 12, and the like. The game also has an album function that can store the game screen as a commemorative photo. Therefore, the user can view the stored game image at any time by storing the favorite scene.
[0021]
The game program can be made resident in the mobile phone 12. For example, even when the game is not played, a standby image is displayed on the display 24 of the mobile phone 12 in the standby state. The standby image in the present embodiment displays game characters appearing in the game. Further, in the present embodiment, the standby image changes according to an event that occurs based on the current time, a change in the state of the mobile phone 12, and the like. In other words, the game program displays a predetermined standby screen on the display 24 in response to the occurrence of an event. The standby image is displayed based on image data acquired by transmitting data indicating a distribution request (download request) to the game server 20, image data stored in the mobile phone 12, and the like. The game program is configured to start the game when a predetermined operation is performed when the standby screen is displayed.
[0022]
FIG. 2 shows an example of a screen (game screen, standby screen, etc.) displayed on the display 24 of the mobile phone 12. In the following description, the standby screen will be described as an example, but the same applies to the game screen. In the case of a game screen, a menu guidance display or the like is separately displayed. In the example of FIG. 5, a standby image including a game character portion 32 and a background portion (portion other than the game character portion 32) 34 is displayed on the standby screen 30. In the following, this screen will be explained as an example.
[0023]
In the game system 10 according to the present embodiment, the background portion of the standby screen is expressed with a smaller number of colors than the character portion. That is, the background portion, which is a subordinate portion that is less important than the character portion that is the main portion of the standby screen, is expressed with a reduced number of colors. For example, in the present embodiment, the background portion is expressed by four gradations of a predetermined color.
[0024]
At this time, if something that gives the user a sense of the season (for example, cherry blossoms or snow) is displayed in the background portion of the standby image, the number of colors in the background portion is suppressed (the background portion is a predetermined color). If this is expressed with a predetermined gradation, the seasonal feeling given to the user is limited. Therefore, in the game system 10, the background portion is expressed by a predetermined gradation of a predetermined color, and the predetermined color is controlled to be an appropriate color that gives the user a sense of the season. In this embodiment, by changing the predetermined color based on the current date or time in the game space, the standby image can have a seasonal feeling based on the current date and time.
[0025]
Furthermore, in the game system 10, image data for displaying a character portion as shown in FIG. 3 and image data for displaying a background portion as shown in FIG. 4 are prepared separately. That is, in the game system 10, the standby image is composed of a combination of these image data. Therefore, when delivering a standby image, a combination of these image data is delivered. The mobile phone 12 displays a standby screen based on the distributed image data. By doing so, the game system 10 can reduce the weight of the entire image data related to the distribution of the standby image, and can reduce the amount of data communication related to the distribution.
[0026]
FIG. 5 is a functional block diagram realized in the game system 10. This figure mainly shows those related to the present invention. As shown in the figure, the game system 10 includes an image data storage unit 40, an image data distribution unit 42, an image data reception unit 44, and an image output unit 46. The image data storage unit 40 includes a game character image data storage unit 50 and a background image data storage unit 52. The image data distribution unit 42 includes a game character image data distribution unit 54 and a background image data distribution unit 56. The image data receiving unit 44 includes a game character image data receiving unit 58 and a background image data receiving unit 60. The image data storage unit 40 and the image data distribution unit 42 may be provided in the game data distribution device 18, and the image data reception unit 44 and the image output unit 46 may be provided in the mobile phone 12.
[0027]
The image data storage unit 40 is mainly configured by the game database 22. The image data distribution unit 42 mainly includes a CPU, a memory such as a RAM and a ROM, and a known communication interface. The image data receiving unit 44 mainly includes a known communication interface. The image output unit 46 mainly includes a CPU, a memory such as a RAM and a ROM, and the display 24. For these functions, the game server 20 as a computer executes a program provided via various computer-readable information storage media such as a CD-ROM, a DVD-ROM, and a memory card, and the mobile phone 12 as a computer. This is realized by executing a game program that is downloaded.
[0028]
The image data storage unit 40 stores game character image data (predetermined region image data) for displaying a game character region (predetermined region) of a game image or a standby image (target image). The image data storage unit 40 also displays background image data (outside the predetermined area image data) for displaying a background area (an area other than the predetermined area) that is an area other than the game character area of the game image or the standby image (target image). ) Is memorized.
[0029]
In the present embodiment, the game character image data and the background image data are configured by an index color method. For example, the background image data includes palette data as shown in FIG. The palette data defines colors used in the image. Each pixel of the image data stores index information for referring to the color defined in the palette data. When the background image data is expressed by four gradations of a predetermined color as in the present embodiment, the four gradations of the predetermined color may be defined in the palette data. Specifically, the RGB value of the predetermined color may be stored in association with the index “1”. Further, in correspondence with the indexes “2”, “3”, and “4”, the RGB values of the predetermined color may be stored by 3/4, 1/2, and 1/4 times, respectively. .
[0030]
Similarly to the background image data, the game character image data also includes palette data. However, unlike the background image, many colors are defined in the palette data included in the game character image data in order to express the game character image clearly. Thus, in this embodiment, the background image data and the game character image data are configured in different image formats. Here, the “different image formats” are not limited to the case where the color expression method is the same and the number of colors used is different or the palette data is different, but the color expression method itself (for example, index color or A full color, etc.), an image storage format, an image compression method, an image format, and the like are different.
[0031]
The image data distribution unit 42 distributes the game character image data to the mobile phone 12. The image data distribution unit 42 distributes the background image data to the mobile phone 12. In addition, the image data distribution unit 42 distributes game character image data and background image data corresponding to a distribution request, for example, in association (relation). Further, the image data distribution unit 42 performs distribution at a predetermined distribution timing such as when an image data distribution request is received from the mobile phone 12, for example.
[0032]
Here, a table configuration for managing images or image data to be distributed in the image data storage unit 40 will be described.
[0033]
For example, an image information table as shown in FIG. 7 is stored in the image data storage unit 40. As shown in the figure, in the image information table, game character image identification information for identifying a game character image constituting the image in association with an image ID (image identification information) for identifying an image to be distributed. A combination of (for example, a game character image name) and background image identification information for identifying a background image (for example, a background image name) is stored. At the image distribution timing, this table is referred to, the game character image and the background image that constitute the image to be distributed are acquired, and image data for displaying these images is distributed to the mobile phone 12.
[0034]
In the present embodiment, one image data for displaying the game character image is prepared for each game character image. For example, “game character image data A” is prepared as image data for displaying “game character image A”. Each game character image identification information is associated with game character image data identification information for identifying the image data (image data identification information such as the image data name and the storage location of the image data), and image data separately. What is necessary is just to make it memorize | store in the memory | storage part 40. FIG.
[0035]
Further, as described above, in the present embodiment, the background image has a variation according to the season. Specifically, in the present embodiment, the background image data is expressed by four gradations of a predetermined color, and the predetermined color (hereinafter referred to as background reference color) changes based on the distribution execution date. It has become. That is, the image data distribution unit 42 distributes background image data based on the current date and time in the game space. In other words, the image data distribution unit 42 changes the background reference color of the background image data related to distribution based on the current date and time in the game space.
[0036]
For example, when the background image data is distributed, the image data distribution unit 42 sets the palette data included in the background image data to be distributed based on the current date or time in the game space or the background image data. Should be distributed. In this case, for example, a background reference color information table as shown in FIG. 8 may be stored in the image data storage unit 40. As shown in the figure, the background reference color information table may store a background reference color (RGB value indicating the color) in association with a predetermined period. In the example of the figure, the background reference color is stored for each period corresponding to each season. In this case, the image data distribution unit 42 acquires RGB values corresponding to a period to which the current date and time in reality or game space belongs, and sets palette data included in the background image data to be distributed based on the RGB values. What should I do? As described above, the storage capacity of the game server 20 and the game database 22 necessary for storing the background image data can be saved.
[0037]
Further, for example, background image data for displaying the same background image and different palette data may be prepared in advance. In this case, for example, a background image information table as shown in FIG. 9 may be stored in the image data storage unit 40. As shown in the figure, in the background image information table, for each background image (background image identification information), background image data identification information prepared for each predetermined period (for example, the background image data name and the background image data) Storage location etc.) may be stored. In the example of the figure, for each background image, a background image data name is stored for each period corresponding to each season. In this case, the image data distribution unit 42 may read and distribute the background image data for displaying the target background image corresponding to the period to which the current date and time in the game space belongs. .
[0038]
The image data receiving unit 44 receives game character image data from the game server 20. Further, the image data receiving unit 44 receives background image data from the game server 20.
[0039]
The image output unit 46 displays (outputs) a game image and a standby image on the display 24 based on the game character image data and the background image data. The image output unit 46 may draw an image based on the game character image data after drawing an image based on the background image data. Further, the game image and the standby image may be displayed on the display 24 by combining the background image data and the game character image data.
[0040]
Next, processing executed in the game server 20 will be described. FIG. 10 is a flowchart showing processing executed in the game server 20 when an image is distributed. This process is executed at a predetermined distribution timing. For example, the distribution timing is when an image distribution request is received from the mobile phone 12. In this case, identification information (image ID) of an image to be distributed is acquired based on the image distribution request, and this process is executed to distribute the image. This process is realized by executing a program in the game server 20.
[0041]
As shown in the figure, the image data distribution unit 42 first acquires the current date and time (S101). If it is the current date and time in reality, it is acquired based on the timekeeping function provided in the game server 20. Further, if it is the current date and time in the game space, it is obtained from means for managing the current date and time in the game space, such as game data managed in the game database 22, for example.
[0042]
Next, the image data distribution unit 42 reads game character image data to be distributed (S102). Specifically, the game character image name associated with the image ID to be distributed is acquired from the image information table (see FIG. 7), and image data for displaying the game character image is read.
[0043]
Next, the image data distribution unit 42 reads background image data to be distributed (S103). Specifically, the background image name associated with the image ID to be distributed is acquired from the image information table (see FIG. 7). For example, the background image data for displaying the background image is read from the image data storage unit 40, and the palette data included in the background image data is set based on the current date and time acquired in S101. Good. In this case, the image data distribution unit 42 reads the RGB value of the reference color corresponding to the period including the current date and time from the background reference color information table (see FIG. 8). Then, the RGB value is set as the RGB value corresponding to the index “1” of the palette data included in the background image data. Further, RGB values corresponding to the indexes “2”, “3”, and “4” are set by multiplying the RGB values by 3/4, 1/2, and 1/4. Further, for example, background image data to be distributed may be read from the image data storage unit 40 based on the current date and time acquired in S101. In this case, the image data distribution unit 42 is the background image data for displaying the target background, and the background image data name corresponding to the period including the current date and time is stored in the background image information table (see FIG. 9). Get from. Then, background image data is read based on the background image data name.
[0044]
Then, the image data distribution unit 42 distributes the game character image data read in S102 and the background image data read in S103 to the mobile phone 12 (S104). When the distribution of these image data ends normally, this process ends.
[0045]
In the game system 10 described above, on the game screen or the standby screen including the game character display portion, the portions other than the game character display portion are expressed by a predetermined gradation of a predetermined color. In other words, on the game screen or the standby screen, there is an expression method between a game character display portion that is a main portion that should be expressed with high image quality as much as possible and a portion other than a game character display portion that is a subordinate portion that may have low image quality. To be different. Then, the image data for displaying the game screen or the standby screen is stored separately into image data for displaying the game character display portion and image data for displaying a portion other than the game character display portion. And is supposed to deliver. When an image including a main area and a sub area having different personalities is stored and distributed as one image data, the data format of the sub area must be matched with the data format of the main area, resulting in increased waste. Therefore, according to the game system 10, the data amount of the image data for displaying the game screen or the standby screen can be reduced as a whole, and the data communication amount related to the distribution of the image data can be reduced. Will be able to.
[0046]
In addition, in a case where a sense of season is expressed in a part other than the game character display part, for example, the background display part, if the part is expressed by a predetermined gradation of a predetermined color, the seasonal feeling given to the user is limited. End up. Therefore, in the game system 10, the predetermined color is controlled based on the current date and time in the real or virtual space. That is, the predetermined color is adapted to the season to which the current date and time belongs.
[0047]
Note that the game system 10 has an album function for the user to save an arbitrary game screen. According to this album function, the user can view favorite game images at any time by saving favorite scenes. Hereinafter, the configuration and the like related to the album function will be described.
[0048]

When a predetermined operation is performed by the user, information for identifying game character image data for displaying the game screen (image) (for example, game character image data name) and information for identifying background image data (for example, background image) Data name) is transmitted to the game server 20 as an image registration request together with the user ID.
[0049]
In the game database 22, for example, an image registration table as shown in FIG. 11 is stored. As shown in the figure, in the image registration table, game character image data identification information (game character image data name in the example in the figure) and background image data identification information (in the example in the figure) are associated with the user ID. , Background image data name). When the game server 20 receives the image registration request from the mobile phone 12, the game server 20 registers the contents in the image registration table.
[0050]
When a predetermined operation for referring to the stored game image is performed by the user, the game server 20 acquires game character image data identification information and background image data identification information based on the image registration table, and these images are acquired. The image data identified by the data identification information is distributed. An image desired by the user is displayed on the display 24 of the mobile phone 12 based on these image data.
[0051]
Note that the image registration table is not limited to that illustrated in FIG. 11, and a combination of game character image identification information (for example, game character image name), background image identification information (for example, background image name), and date / time information is used by the user. You may make it memorize | store corresponding to ID. In this case, the image registration request from the mobile phone 12 may include a user ID, game character image identification information, and background image identification information. You may make it include the delivery date and time when these images were delivered. And the game server 20 which received this image registration request registers the content of this image registration request in an image registration table. As for the date and time information, when the image registration request includes the delivery date and time, the delivery date and time may be registered as date and time information, or the current date and time may be registered as date and time information.
[0052]
