[1. Hardware configuration of display control device]
Hereinafter, examples of embodiments of the present invention will be described in detail with reference to the drawings. The display control apparatus according to the embodiment of the present invention is realized by, for example, a mobile game machine, a mobile phone (smart phone), a mobile information terminal, or the like.

  FIG. 1 is a diagram illustrating an example of an appearance of a display control device. FIG. 2 is a diagram illustrating an example of a hardware configuration of the display control apparatus. As shown in FIGS. 1 and 2, the display control device 10 includes a control unit 11, a storage unit 12, a communication unit 13, an operation unit 14, a sensor 15, a touch panel 16, and a display unit 17.

  The control unit 11 includes, for example, one or a plurality of microprocessors. The control unit 11 executes processing according to an operating system or other program stored in the storage unit 12.

  The storage unit 12 includes a main memory and a nonvolatile memory. A program executed by the control unit 11 is stored in the nonvolatile memory. For example, this program is downloaded from a server device via a communication network such as the Internet and stored in a nonvolatile memory. Alternatively, this program is copied from a computer-readable information storage medium such as a memory card and stored in a nonvolatile memory. In the main memory, a program read from the nonvolatile memory and data necessary when the control unit 11 executes processing are written.

  The communication unit 13 is for performing data communication. For example, the communication unit 13 performs data communication according to an instruction from the control unit 11.

  The operation unit 14 includes, for example, a button, a stick (lever), a keyboard, and the like, and is used for a user to perform an operation.

  The sensor 15 includes one or a plurality of sensors for detecting the attitude of the housing of the display control device 10. The posture of the display control device 10 changes according to a user operation. For example, when the user tilts or rotates the hand holding the display control device 10, the posture of the display control device 10 changes. For example, the sensor 15 includes at least one of an acceleration sensor (acceleration detection means) and a gyro sensor (angular velocity detection means). In the following description, it is assumed that both the acceleration sensor and the gyro sensor are built in the display control device 10.

  The acceleration sensor detects the acceleration of the display control device 10. For example, an acceleration generated in the display control device 10 by the operation of the user who has the display control device 10 is detected by the acceleration sensor. The acceleration sensor detects accelerations in three axial directions (X-axis direction, Y-axis direction, and Z-axis direction) orthogonal to each other. As shown in FIG. 1, the display control device 10 has a rectangular shape, the X axis corresponds to the longitudinal direction of the display control device 10, and the Y axis corresponds to the short direction of the display control device 10. . Further, the Z axis corresponds to the depth direction of the display control device 10.

  The gyro sensor detects the angular velocity of the display control device 10. For example, an angular velocity generated in the display control device 10 by the operation of the user who has the display control device 10 is detected by the gyro sensor. The gyro sensor detects angular velocities of three axes (X axis, Y axis, and Z axis) orthogonal to each other. That is, the gyro sensor detects the amount of rotation per unit time when the display control device 10 rotates about the X axis as a rotation axis. Similarly, the gyro sensor detects the amount of rotation per unit time when the display control apparatus 10 rotates about the Y axis as a rotation axis. Further, the gyro sensor detects a rotation amount per unit time when the display control apparatus 10 rotates about the Z axis as a rotation axis.

  Information indicating the detection result of the sensor 15 is supplied to the control unit 11 every predetermined time (for example, 1/60 seconds). For example, the control unit 11 determines whether the display control device 10 is shaken by the user based on the detection result of the sensor 15.

  The touch panel 16 is a general touch panel and detects a position touched by a user. The touch panel 16 can detect a plurality of positions touched by the user. For example, a capacitive touch panel is used as the touch panel 16. In the capacitive touch panel, a position touched by the user is detected based on a change in electric charge generated when the surface of the touch panel is touched by the user. The position touched by the user is, for example, as shown in FIG. 1, Xs-Ys with the upper left vertex of the touch panel 16 as the origin O and the right direction and the lower direction as the Xs axis positive direction and the Ys axis positive direction, respectively. Represented by coordinate values in the coordinate system.

  The touch panel 16 supplies information corresponding to the position touched by the user to the operating system. Based on the information supplied from the touch panel 16, the operating system acquires the position touched by the user.

  Note that the touch panel 16 is provided on a display unit 17 described later. For this reason, the user can designate a position in the screen displayed on the display unit 17 by touching the surface of the touch panel 16. Note that the user may make his / her finger (hand) contact the surface of the touch panel 16, or the user may make a part other than the finger (hand) contact the surface of the touch panel 16. In addition, for example, an object (touch pen or the like) held by the user may be brought into contact with the surface of the touch panel 16.

  The display unit 17 is, for example, a liquid crystal panel. The display unit 17 displays a screen according to instructions from the control unit 11.

  The display control device 10 may include an optical disk drive or a memory card slot. The optical disk drive is for reading a program and data recorded on an optical disk (information storage medium). The memory card slot is for reading a program and data stored in a memory card (information storage medium). The program and data may be supplied to the display control device 10 via an optical disk or a memory card and stored in the storage unit 12 (nonvolatile memory). The program and data described as being stored in the information storage medium may be acquired from the network via the communication unit 13.

[2. Overview of processing executed by display control device]
In this embodiment, the display control device 10 executes a soccer game in which a soccer game is played in a virtual three-dimensional space simulating a soccer game venue by executing a game program read from the storage unit 12. Will be described. When the soccer game is started, for example, a virtual three-dimensional space is constructed in the storage unit 12.

  FIG. 3 is a diagram illustrating an example of a virtual three-dimensional space. The virtual three-dimensional space 20 is a virtual three-dimensional space in which three coordinate axes (Xw axis, Yw axis, and Zw axis) orthogonal to each other are set. The position of each object arranged in the virtual three-dimensional space 20 is specified by the three-dimensional coordinates of the world coordinate system (Xw-Yw-Zw coordinate system), for example.

  As shown in FIG. 3, a field 22 that is an object representing a soccer field is arranged in the virtual three-dimensional space 20. On the field 22, between the team operated by the user (hereinafter referred to as “user team”) and the team operated by the opponent (computer or other user) (hereinafter referred to as “opponent team”). A soccer game will be held.

  On the field 22, two goal lines 24a and 24b, two touch lines 26a and 26b, and a center line 28 are represented. On the field 22, a goal 30 that is an object representing a soccer goal, a character 32 that is an object representing a soccer player belonging to the user team, and a character that is an object representing a soccer player belonging to the opponent team. 34 and a ball 36, which is an object representing a soccer ball (moving object), are arranged. Although omitted in FIG. 3, eleven characters 32 belonging to the user team and eleven characters 34 belonging to the opponent team are arranged on the field 22.

  Any of the characters 32 belonging to the user team operates based on the user's operation, and the other characters 32 and the characters 34 belonging to the opponent team operate autonomously under a given behavior algorithm. .

  When the character 32 (34) and the ball 36 approach each other, the character 32 (34) and the ball 36 are associated with each other under a predetermined condition. In this case, the moving action of the character 32 (34) is a dribbling action. Hereinafter, the state in which the ball 36 is associated with the character 32 (34) will be described as “the character 32 (34) holds the ball 36”.

  A virtual camera 38 (viewpoint) is set in the virtual three-dimensional space 20. A game screen representing a state in which the virtual three-dimensional space 20 is viewed from the virtual camera 38 is displayed on the display unit 17. The game screen is generated by converting the vertex coordinates of each object arranged in the virtual three-dimensional space 20 from the world coordinate system to the screen coordinate system using a predetermined coordinate conversion calculation.

  FIG. 4 is a diagram illustrating an example of the game screen. In the example shown in FIG. 4, the virtual camera 38 is controlled from a so-called overhead view so that the virtual camera 38 looks down on the ball 36 or the character 32 (34) associated with the ball 36 from a predetermined oblique position in the field 22. Controlled. The position and line-of-sight direction of the virtual camera 38 are controlled so as to follow the ball 36 or the character 32 (34) associated with the ball 36.

  For example, the Xw coordinate position of the virtual camera 38 is determined based on the Xw coordinate position of the ball 36 or the character 32 (34) associated with the ball 36, and the Yw coordinate and Zw coordinate positions of the virtual camera 38 are predetermined values. Thus, the position of the virtual camera 38 is controlled. Further, for example, a predetermined direction (for example, a moving direction of the ball 36 or a moving direction of the character 32 (34) associated with the ball 36) from the position of the ball 36 or the character 32 (34) associated with the ball 36 is predetermined. The line-of-sight direction of the virtual camera 38 is controlled so that the position separated by the distance becomes the gazing point of the virtual camera 38.

  In the present embodiment, when the user changes the attitude of the display control device 10, the method for controlling the position and line-of-sight direction of the virtual camera 38 is switched from the above-described overhead view viewpoint to the first person viewpoint. Here, when the user is in a state in which the surface of the display control device 10 faces in the Y-axis direction (that is, a state in which the display control device 10 is set substantially vertical), the virtual camera 38 is controlled from an overhead viewpoint. On the other hand, when the user tilts the display control device 10, the virtual camera 38 is controlled from the first-person viewpoint of the character 32 designated by the user.

  FIG. 5 is a diagram illustrating an example of the game screen 40 when the virtual camera 38 is controlled from the first person viewpoint. As shown in FIG. 5, the position of the virtual camera 38 is the position of the viewpoint (face position) of the character 32 specified by the user on the touch panel 16 or the like, and the line-of-sight direction of the virtual camera 38 is the representative direction ( For example, the line of sight of the character 32).

  As described above, the display control apparatus 10 of the present embodiment is configured to switch the viewpoint control of the virtual camera 38 between the overhead view viewpoint and the first person viewpoint according to the attitude of the display control apparatus 10. Hereinafter, this configuration will be described in detail.

[3. Functions realized in display control apparatus]

  The representative direction of the object is a direction associated with the object. For example, the gaze direction of the character 32 (34), the face direction, the direction from the face to the vicinity of the feet, the front direction of the body, the moving direction, and the ball 36 Is at least one of the moving directions.

  Further, here, the game data storage unit 50 stores information for identifying an object designated by the user among a plurality of objects arranged in the virtual three-dimensional space 20. The object designated by the user is an object that is determined based on the user's operation among the plurality of objects arranged in the virtual three-dimensional space 20. In the present embodiment, among objects displayed on the game screen 40 (for example, the character 32 of the user team), an object touched by the user with the touch panel 16 corresponds to an object designated by the user.

  Note that the game execution unit 52 functions as a means for acquiring or updating data stored in the game data storage unit 50. Further, the data stored in the game data storage unit 50 is not limited to the above example. In addition, for example, the game data storage unit 50 may store game status data (for example, data indicating the battle status) indicating the status of the game being executed, and relates to various images displayed on the game screen 40. Data may be stored.

The game execution unit 52 operates the object in the virtual three-dimensional space 20 in accordance with the progress of the game or the user's operation. The game execution unit 52 updates data indicating the current state of the virtual three-dimensional space 20 based on the motion of each object.

  In addition, the game execution unit 52 causes the display unit to display an image showing a state where the virtual three-dimensional space 20 in which the object is arranged is viewed from a given viewpoint (for example, the virtual camera 38). The game execution unit 52 refers to data indicating the current state of the virtual three-dimensional space 20, and coordinates the object in the field of view of the virtual camera 38 controlled by the first viewpoint control unit 60 or the second viewpoint control unit 62. By performing the conversion, display control of the game screen 40 is performed.

  Although details will be described later, the game execution unit 52 performs first viewpoint control (for example, overhead view viewpoint) by the first viewpoint control unit 60 and second viewpoint control unit 62 based on the determination result of the posture determination unit 56. With the second viewpoint control (for example, the first person viewpoint), the control method of the position and line-of-sight direction of the virtual camera 38 is switched.

[3-3. Attitude detection unit]
The attitude detection unit 54 detects the attitude of the display control device 10 or the operation means (details will be described later). The posture detection unit 54 detects the posture based on a detection signal from the acceleration detection means or the angular velocity detection means (for example, the sensor 15).

[3-4. Posture determination unit]
The posture determination unit 56 determines whether or not the posture detected by the posture detection unit 54 is a given posture. The given posture is a posture in which a deviation between the posture detected by the posture detecting unit 54 and the reference posture is within a predetermined range. For example, an angle formed between the posture detected by the posture detecting unit 54 and the reference posture is The posture is within a predetermined range.

  FIG. 7 is a diagram for explaining a determination method of the posture determination unit 56. As shown in FIG. 7, in the present embodiment, the reference posture is a state where the surface of the display control device 10 faces the reference direction (for example, a state where the surface of the display control device 10 faces the Y-axis direction (vertical direction)). ).

The posture determination unit 56 determines whether or not the posture detected by the posture detection unit 54 is greater than or equal to the reference angle, the angle θ _P between the surface of the display control device 10 and the Y axis (reference direction). Posture determination unit 56, when the angle theta _P is determined to be a predetermined angle or more, determines the posture detected by the posture detecting section 54 to be given posture.

[3-5. Designated reception desk]
The designation accepting unit 58 accepts designation of any of the plurality of objects by the user from among a plurality of objects (for example, the character 32) arranged in the virtual three-dimensional space 20. The designation receiving unit 58 receives the designation of the character 32 by the user based on the detection signal from the operation unit 14 or the touch panel 16.

[3-6. First viewpoint control unit]
The first viewpoint control unit 60 controls the position of the viewpoint and the line-of-sight direction when it is determined that the posture detected by the posture detection unit 54 is not a given posture. The first viewpoint control unit 60 controls the position and the line-of-sight direction of the virtual camera 38 based on the first control method (for example, based on a given position and line-of-sight direction, or the character 32 or the ball 36). To do.

  For example, the first viewpoint control unit 60 controls the position of the virtual camera 38 and the line-of-sight direction so that the positional relationship between the object arranged in the virtual three-dimensional space 20 and the virtual camera 38 maintains a given relationship. . Here, the first viewpoint control unit 60 moves the virtual camera 38 away from the character 32 and controls the line-of-sight direction of the virtual camera 38 and the representative direction of the character 32 as compared with the case where the control by the second viewpoint control unit 62 is performed. The position of the virtual camera 38 and the line-of-sight direction are controlled so as to increase the angle.

FIG. 8 is a diagram for explaining a method of controlling the virtual camera 38 by the first viewpoint control unit 60. For example, the first viewpoint control unit 60 controls the position of the virtual camera 38 so that the distance D between the virtual camera 38 and the character 32 is equal to or greater than the reference distance. Further, for example, the first viewpoint control unit 60 is configured so that the angle θ _V formed by the visual line direction V ₁ of the virtual camera 38 and the representative direction V _{2 of the} object (for example, the visual line direction of the character 32) is equal to or larger than the reference angle. controlling the viewing direction _{V 1} of the virtual camera 38.

[3-7. Second viewpoint control unit]
When it is determined that the posture detected by the posture detection unit 54 is a given posture, the second viewpoint control unit 62 brings the viewpoint closer to the object than when control by the first viewpoint control unit 60 is performed. (For example, the virtual camera 38 is brought closer to the designated character 32), and the viewpoint position and the line-of-sight direction V ₁ are set so that the angle θ _V between the line-of-sight direction V _{1 of the} viewpoint and the representative direction V _{2 of the} object is reduced. And control. When the second viewpoint control unit 62 controls the position of the virtual camera 38 and the line-of-sight direction V ₁ based on the second control method (for example, based on the position of the designated character 32 and the representative direction V ₂ ). It can also be said.

  FIG. 9 is a diagram for explaining a method of controlling the virtual camera 38 by the second viewpoint control unit 62. The second viewpoint control unit 62 controls the position of the virtual camera 38 so that the distance D between the virtual camera 38 and the character 32 is less than the reference distance.

Only the viewpoint control method of the virtual camera 38 can be easily switched.

  In addition, when the display control apparatus 10 is tilted, the first-person viewpoint of the character 32 designated by the user can be designated, which character 32 the first-person viewpoint of the user can designate.

[5. Modified example]
The present invention is not limited to the embodiment described above. Modifications can be made as appropriate without departing from the spirit of the present invention.

  FIG. 11 is a functional block diagram of a modified example. As shown in FIG. 11, in addition to the functions of the embodiment, the display control apparatus 10 according to the modified example includes a status acquisition unit 64, a representative direction change unit 66, a role acquisition unit 68, an operation system change unit 70, A first display control unit 72, a second display control unit 74, a limiting unit 76, and an associating unit 78 are included. Each of these functions is realized by the control unit 11 executing a program stored in the storage unit 12. Each of these functions is realized mainly by the control unit 11.

  (1) For example, in the embodiment, the aspect in which the virtual camera 38 is controlled to face the line of sight of the character 32 when the display control device 10 is tilted has been described, but depending on the state of the game being executed When the display control device 10 is tilted, the direction in which the virtual camera 38 faces may be changed. For example, when the character 32 belonging to the user team holds the ball 36, the character 34 belonging to the opponent team holds the ball 36 such that the virtual camera 38 faces the goal 30 of the opponent team. If it is held, the virtual camera 38 may face the direction of the goal 30 of the user team.

  The display control apparatus of the modification example (1) includes a situation acquisition unit 64 and a representative direction change unit 66. The situation acquisition unit 64 acquires the data stored in a unit (for example, the game data storage unit 50) that stores data indicating the situation of the game being executed. The situation acquisition unit 64 acquires data indicating the current state of the virtual three-dimensional space 20, for example.

Representative direction changing unit 66 changes the representative direction V ₂ of the object based on the situation of the game being executed. For example, the representative direction changing unit 66 determines the representative direction V ₂ associated with the situation of the game being executed based on the association between the situation of the game being executed and the representative direction V _2. Set to.

Figure 12 is a diagram showing the association between the game situation during running and the representative direction V _2. Data indicating the association is stored in the game data storage unit 50. Further, the association may be in a table format or a mathematical expression format. The same applies to the association described below.

For example, as shown in FIG. 12, the user team is in attack state (state character 32 belonging to the user team holds the ball 36), the representative direction V _2, the position and the goal of the opponent team of the virtual camera 38 30. Further, for example, in the state in opponent team attack, the representative direction V ₂ is a direction connecting the goal 30 position and the user team of the virtual camera 38.

For example, the second display control unit 74 determines the viewing direction V ₁ of the virtual camera 38 so that the representative direction V ₂ changed by the representative direction changing unit 66 and the viewing direction V ₁ of the virtual camera 38 substantially coincide with each other. Will do.

According to a variant (1), can be changed according to the situation of the game being executed, the viewing direction V ₁ of the virtual camera 38 by tilting the display control unit 10.

(2) Further, for example, depending on the position of the character 32 specified by the user, the representative direction V ₂ may be different. If the character 32 specified by the user is forward, the virtual camera 38 faces the goal 30 of the opponent team when the display control device 10 is tilted, and the character 32 specified by the user is a defender. When the display control device 10 is tilted, the virtual camera 38 may face the goal 30 of the user team.

  The game data storage unit 50 of the modified example (2) stores information regarding the role (for example, position) of the character 32. Here, a plurality of roles are prepared, and at least one of the plurality of roles is given to each character 32. For example, four types of positions of forward, midfielder, defender, and goalkeeper are prepared, and at least one of these four types is given to the character 32. The position given to the character 32 may be designated by the user or may be designated in advance.

  The display control device of the modification (2) includes a role acquisition unit 68. The role acquisition unit 68 acquires the information stored in a unit (for example, the game data storage unit 50) that stores information related to the role of the object in the game.

Representative direction changing portion 66 of the modified example (2) of an object (e.g., character 32) to determine the representative direction V ₂ of the object based on the role. Representative direction changing section 66, based on the association of the role of the character 32 and the representative direction V _2, a representative direction V ₂ associated with the role of the character 32 is set to the character 34 designated by the user.

Figure 13 is a diagram showing the association between the role of the character 32 and the representative direction V _2. Data indicating the association is stored in the game data storage unit 50. Further, the association may be in a table format or a mathematical expression format. As shown in FIG. 13, for example, if the character 32 specified by the user is forward, the representative direction V ₂ is a direction connecting the goal 30 position and the opponent team of the virtual camera 38. For example, if the character 32 designated by the user is a defender, the representative direction V ₂ is a direction connecting the position of the virtual camera 38 and the goal 30 of the user team.

According to a variant (2), it can be in accordance with the position of the character 32 specified by the user, to change the viewing direction V ₁ of the virtual camera 38 by tilting the display control unit 10.

  (3) Also, for example, an operation system for operating the character 32 in the case where the display control device 10 is set up and the overhead viewpoint control is performed, and in the case where the first-person viewpoint control is performed by tilting the display control device 10. It may be changed.

  The display control apparatus of the modification (3) includes an operation system changing unit 70. The operation system changing unit 70 moves the object (for example, the character 32) when the viewpoint control by the first viewpoint control unit 60 is executed and when the viewpoint control by the second viewpoint control unit 62 is executed. Different operation system to operate. The operation system is an association between the operation content and the action of the character 32. The character 32 performs an action associated with the user's operation.

  FIG. 14 is a diagram illustrating an example of an operation system. As illustrated in FIG. 14, the operation system change unit 70 changes the operation system based on the association between the first viewpoint control unit 60 or the second viewpoint control unit 62 and the operation system. The operation system changing unit 70 causes the character 32 to operate with an operation system associated with the one of the first viewpoint control unit 60 and the second viewpoint control unit 62 that currently controls the viewpoint of the virtual camera 38. Set the operation system.

  For example, as shown in FIG. 14, an operation for moving the character 32 when the first viewpoint control unit 60 performs viewpoint control and when the second viewpoint control unit 62 performs viewpoint control. The members (here, the operation unit 14 and the touch panel 16) may be different.

  According to the modification (3), the operation system can be changed according to the viewpoint control method of the virtual camera 38.

  (4) For example, when an external monitor is connected to the display control device 10, viewpoint control according to the attitude of the display control device 10 is performed on the display unit 17 of the display control device 10. About an external monitor, you may make it display the game screen 40 with a bird's-eye view viewpoint.

Further, the game control device 80 is connected to the display control device 10 through a wired or wireless network so as to be able to transmit and receive data.

  The external monitor 82 is connected to the display control device 10 and the game control device 80 via a wired or wireless network so as to be able to transmit and receive data, and displays various images. Here, the display unit 17 included in the display control apparatus 10 corresponds to the first display unit, and the external monitor corresponds to the second display unit. On the other hand, the display unit 17 provided in the same casing as the display control device 10 and the operation unit 14 corresponds to a first display unit. The user plays the game by operating the operation unit 14 or the touch panel 16 while grasping the display control device 10 and visually recognizing the display unit 17 and the external monitor 82.

  The display control apparatus of the modification (4) includes a first display control unit 72 and a second display control unit 74. The first display control unit 72 displays, as a first display unit and a second display, an image showing a state in which the virtual three-dimensional space 20 is viewed from the viewpoint (for example, the virtual camera 38) controlled by the first viewpoint control unit. Display on the means. When it is determined that the posture of the display control device 10 is not a given posture, the first display control unit 72 performs a virtual three-dimensional space from the virtual camera 38 controlled from the overhead view point on the display unit 17 and the external monitor 82. An image showing a state of viewing 20 is displayed.

  When it is determined that the posture detected by the posture detector 54 is a given posture, the second display controller 74 is displayed by the display control of the first display controller 72 on the first display means. Instead of the image, an image showing the virtual three-dimensional space 20 viewed from the viewpoint controlled by the second viewpoint control unit is displayed. When it is determined that the posture of the display control device 10 is a given posture, the second display control unit 74 switches the image displayed on the display unit 17 and performs the first-person viewpoint of the character 32 designated by the user. An image showing the virtual three-dimensional space 20 viewed from the virtual camera 38 to be controlled is displayed.

  On the other hand, in the external monitor 82, even when it is determined that the posture detected by the posture detector 54 is a given posture, the first is independent of the posture detected by the posture detector 54. An image showing the virtual three-dimensional space 20 viewed from the viewpoint controlled by the viewpoint control unit 60 is displayed.

  According to the modification (4), since the viewpoint control of the image displayed on the display unit 17 at the user's hand can be changed without changing the viewpoint control of the image displayed on the external monitor 82, the user Can confirm how the virtual three-dimensional space 20 is viewed from a plurality of directions by a relatively simple operation.

  (5) For example, the viewpoint control by the second viewpoint control unit 62 may be performed only when the situation of the game being executed is in a given situation.

  The display control apparatus according to the modification (5) includes a limiting unit 76. The limiting unit 76 determines whether to limit the viewpoint control by the second viewpoint control unit 62 based on the state of the game being executed. The restriction unit 76 determines whether or not the situation of the game being executed is a given situation. The given situation may be a situation predetermined in order to limit the viewpoint control by the second viewpoint control unit 62. For example, the state of the virtual three-dimensional space 20 is the given state (the object arrangement is given). For example, whether the ball 36 and the character 32 (34) are not associated with each other).

  When it is determined that the situation of the game being executed is a given situation, the restriction unit 76 causes the second viewpoint control unit 62 to execute the viewpoint control, and the situation of the game being executed is not the given situation. If the determination is made, the viewpoint control by the second viewpoint control unit 62 is prevented from being performed.

  According to the modified example (5), a situation is determined in which it is not necessary to perform viewpoint control by the second viewpoint control unit 62, and the viewpoint by the second viewpoint control unit 62 is determined when the game being executed is in this situation. You can avoid control.

  (6) In the embodiment, for example, when the user tilts the display control device 10, the first person viewpoint of the character 32 designated by the user has been described. It may be made to become.

  The game execution unit 52 sets any one of the plurality of characters 32 as a user's operation target according to the user's operation or the progress of the game. For example, the game execution unit 52 determines the character 32 to be operated by the user based on the current state of the virtual three-dimensional space 20 (for example, the positional relationship between each character 32 and the ball 36).

The second viewpoint control unit 62 of the modified example (6) is more than the case where the control by the first viewpoint control unit 60 is performed when the posture detected by the posture detection unit 54 is determined to be a given posture. , viewpoint (e.g., the virtual camera 38) close to the operation target of the user, and to reduce the angle theta _V with the representative direction V ₂ of the operation target viewpoint viewing direction V ₁ and user and the position of the viewpoint to control the line-of-sight direction _{V 1.}

When it is determined that the posture detected by the posture detection unit 54 is a given posture, the second viewpoint control unit 62 refers to the content stored in the game data storage unit 50 and operates the user among the characters 32. The character 32 set as the target is specified. Second viewpoint control unit 62, based on the position of the character 32 which is the specified representative direction V _2, will control the position and viewing direction V ₁ of the virtual camera 38.

  According to the modification (6), when the user tilts the display control device 10, the viewpoint control can be switched so that the first-person viewpoint of the character 32 to be operated by the user is obtained.

(7) In addition, for example, the viewpoint control may be performed so that the ball 36 or the representative direction V ₂ of the character 32 holding the ball 36 is set.

  The display control apparatus 10 of the modification (7) includes an association unit 78. The associating unit 78 associates any of a plurality of objects with the moving object. The associating unit 78 associates one of the characters 32 (34) with the ball 36 based on the positional relationship between the ball 36 and the character 32 (34). For example, the associating unit 78 associates the ball 36 with the character 32 (34) closest to the ball 36 among the characters 32 (34) whose distance from the ball 36 is less than a predetermined distance.

When it is determined that the posture detected by the posture detection unit 54 is a given posture, the second viewpoint control unit 62 performs a viewpoint (e.g., virtual) than when control by the first viewpoint control unit 60 is performed. moving objects the camera 38) (e.g., object associated with the balls 36) or moving objects (e.g., close to the character 32), and a representative of the associated object to a moving object or moving object and line-of-sight direction V ₁ of the viewpoint so as to reduce the angle theta _V between the direction V _2, for controlling the position and viewing direction V ₁ of the viewpoint.

For example, if the second viewpoint control unit 62 determines that the posture detected by the posture detection unit 54 is a given posture, the second viewpoint control unit 62 refers to the stored content of the game data storage unit 50 and represents the position of the ball 36 and the representative The direction V ₂ (for example, the moving direction of the ball 36) is specified. Second viewpoint control unit 62, based on the position of the ball 36 that is the specified representative direction V _2, will control the position and viewing direction V ₁ of the virtual camera 38.

Further, for example, when it is determined that the posture detected by the posture detection unit 54 is a given posture, the second viewpoint control unit 62 refers to the stored content of the game data storage unit 50 and is associated with the ball 36. Character 32 is identified. Second viewpoint control unit 62, based on the position of the character 32 which is the specified representative direction V _2, will control the position and viewing direction V ₁ of the virtual camera 38.

However, the overhead view viewpoint and the first person viewpoint are switched according to the attitude of the operation means. You may do it. In this case, the “posture of the display control apparatus 10” described in the embodiment and the above modification can be read as “the posture of the operation means”.

  For example, although the case where the control of the virtual camera 38 is switched between the overhead viewpoint and the first person viewpoint has been described, the combination of the control methods of the first viewpoint controller 60 and the second viewpoint controller 62 is not limited thereto. Based on the determination result of the posture determination unit 56, the viewpoint control of the first viewpoint control unit 60 and the viewpoint control of the second viewpoint control unit 62 may be switched.

For example, the first viewpoint control unit 60 may perform viewpoint control of the virtual camera 38 from the third person viewpoint in which the virtual camera 38 is disposed behind the character 32. In this case, the control method of the virtual camera 38 is switched between the third person viewpoint and the first person viewpoint in accordance with the attitude detected by the attitude detection unit 54. In addition, for example, the second viewpoint control unit 62 arranges the virtual camera 38 at the position of the face of the character 32, and the line-of-sight direction V ₁ of the virtual camera 38 is set so as to see the feet of the character 32. , may be controlled the position and viewing direction V ₁ of the virtual camera 38.

  Further, for example, two or more of the above embodiment and the modified example can be combined.

  Further, for example, in the display control system S, each of the functional blocks may be realized by either the display control device 10 or the game control device 80.
