[Embodiment]
<Overview>
First, prior to explaining an embodiment of the present invention, a brief explanation will be given of a game (hereinafter referred to as "this game") to which an information processing system (hereinafter referred to as "this system") according to one embodiment of the present invention is applied, and the "viewpoint" in this game.
This game is a so-called action game in which the player moves through a virtual space, repeating battles and events set during the game, aiming to clear the game. The player freely controls a character displayed in the virtual space by performing input operations, etc., and progresses through the game by defeating enemy characters in the game using guns, explosives, etc.

In these types of games, two methods are known as the basis for generating game images, i.e., the method for configuring the viewpoint during the game: first-person viewpoint and third-person viewpoint.

First, the first-person viewpoint (subjective viewpoint) is a method of setting the viewpoint during the game at the eye position of the playable character. That is, when generating game images from a first-person viewpoint, a virtual camera is set at the eye position of the playable character.
The advantage of the first-person perspective is that the game image is generated from a perspective close to the player's own perspective, making it easier for the player to feel immersed in the game. In addition, compared to the third-person perspective described below, there is an advantage that the player's controlled character is not displayed in the game image, so the view to check other objects is not obstructed. On the other hand, the first-person perspective is a limited viewpoint from the controlled character, so compared to the third-person perspective described below, there is a problem in that the field of view is narrower and it is difficult to grasp the positional relationship between objects.

In contrast, a third-person viewpoint (objective viewpoint) is a method of setting the viewpoint during the game at a position where the entire game situation, including the character operated by the player, can be confirmed. That is, when generating game images from a third-person viewpoint, a virtual camera is typically set at a position above and behind the operated character.
The advantage of this third-person perspective is that the virtual camera is set far back, so that the angle (field of view) that can be displayed as a game image can be set to be wide. Also, in the third-person perspective, the controlled character and other objects are displayed equally, so the player can easily grasp the positional relationship between each object. On the other hand, the third-person perspective has the problem that it is difficult to empathize with the controlled character because it is displayed in the game image, and it is difficult to feel immersed in the game.

In consideration of these circumstances, this game employs a specification that allows the player to switch between a first-person perspective and a third-person perspective at any time during the game. Specifically, this game will be described as an example in which the game normally progresses from a third-person perspective, and the perspective changes to a first-person perspective when a specific event starts.
As described above, in the prior art, there have been almost no specific methods proposed for changing between a first-person viewpoint and a third-person viewpoint, but possible methods include, for example, simply changing the position of the virtual camera instantaneously, or turning off the lights once and then changing the position of the virtual camera. However, if the position of the virtual camera is changed suddenly, the player may feel uncomfortable due to the sudden change in the game image, and in the worst case, the player may experience motion sickness. Therefore, it is desirable to change the viewpoint in a natural and comfortable manner without impairing the comfort of the player as much as possible.
In the following description, when a character or object is used, it does not mean only one independent character or object, but also includes a part of a character or object (for example, a hand).

<System Configuration>
FIG. 1 is a diagram showing an example of a configuration of an information processing system according to an embodiment of the present invention.
As shown in Fig. 1, the system includes a game device 1 and a server 2. The game device 1 and the server 2 are connected to each other via a predetermined network N such as the Internet. However, the network N is not a required component, and for example, NFC (Near Field Communication), Bluetooth (registered trademark), LAN (Local Area Network), etc. may be used. Note that hereinafter, when simply referring to "images", any image such as "moving images" and "still images" is included.

The game device 1 is used by a player who wishes to use this system. The game device 1 may be a general-purpose home game console, a PC (Personal Computer), a smartphone, a tablet, or the like. The game device 1 executes various processes required for the progress of the game.

The server 2 is managed by an administrator of the system. The server 2 is composed of a general-purpose PC or the like. While communicating with the game device 1 and the like, the server 2 stores and manages various information required for the progress of the game.

<Hardware Configuration>
FIG. 2 shows an example of the hardware configuration of a game device in the information processing system according to one embodiment of the present invention.

As shown in FIG. 2, the game device 1 includes a control unit 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input/output interface 15, an output unit 16, an input unit 17, a memory unit 18, a communication unit 19, and a drive 20.

The control unit 11 is configured with a microcomputer including a CPU, a GPU, a semiconductor memory, etc. The control unit 11 executes various processes according to a program recorded in a ROM 12 or a program loaded from a storage unit 18 to a RAM 13.
The RAM 13 also stores information necessary for the control unit 11 to execute various processes as appropriate.

The control unit 11, ROM 12, and RAM 13 are interconnected via a bus 14. An input/output interface 15 is also connected to this bus 14. An output unit 16, an input unit 17, a memory unit 18, a communication unit 19, and a drive 20 are connected to the input/output interface 15.

The output unit 16 outputs image information, audio information, etc. to a display, a speaker, etc. The image information and audio information output by the output unit 16 are output from the display, the speaker, etc. in a state that can be recognized by a person as an image or audio.

The input unit 17 is composed of a game controller or the like, and inputs various information in response to input operations by the player.

The storage unit 18 is composed of a hard disk drive (HDD) or a solid state drive (SSD), and stores various information. For example, the storage unit 18 stores various game programs, save data, account information, and the like, which are necessary for progressing through the game.

The communication unit 19 controls communications between the device and other hardware devices via a network N, including the Internet.

The drive 20 is provided as necessary. Removable media 31, which may be a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, is appropriately attached to the drive 20. Various programs for executing a game are stored in the removable media 31. The programs read from the removable media 31 by the drive 20 are installed in the storage unit 18 as necessary.
Further, the removable medium 31 can store various information stored in the storage unit 18 in the same manner as the storage unit 18 .

Here, the hardware configuration of the server 2 can be basically the same as the hardware configuration of the game device 1, so a description is omitted. Through the cooperation of such various hardware and software, various processes can be executed in the game device 1 and the server 2.

<Functional configuration>
FIG. 3 is a diagram showing an example of a functional configuration of the game device of FIG. 2 and the server of FIG.
As shown in FIG. 3, the control unit 11 of the game device 1 executes various programs and the like, thereby causing a game processing execution means 60, an input reception means 62, an event management means 64, and a virtual camera control means 66 to function.

The game process execution means 60 of the game device 1 executes various processes relating to the game.
Specifically, the game processing execution means 60 reads out virtual game space objects and textures, etc., included in the game information from a storage unit (not shown) in accordance with various input operations by the player, etc., and generates two-dimensional or three-dimensional images, sounds, etc. related to the game while executing the game program. In other words, the game processing execution means 60 controls the progress of the game by generating and managing the results of operational instructions by the player.
In addition, the game processing execution means 60 transmits various information related to the game to the server 2 as appropriate.

The input receiving means 62 receives information regarding an input operation from a player.
Here, the input information received by the input receiving means 62 includes, for example, information regarding pressing of various buttons provided on the controller which is the input unit 17, information regarding change in position and acceleration of the controller which is the input unit 17 in real space, etc. In this embodiment, the movement of the playable character or a part of the character's body (e.g., a hand) displayed in the virtual space and the position and angle of the virtual camera are determined in response to each piece of input information thus inputted via the input unit 17.

The event management means 64 manages the progress of events in the game based on the input information etc. received by the input reception means 62. Specifically, when the playable character moves to a specified area in the virtual space, the event management means 64 executes various processes to start an event in the game that involves a change of viewpoint.

The virtual camera control means 66 generates a content image relating to the content based on the input information and the position of the virtual camera.
Here, the virtual camera control means 66 is provided with a start point determination means 80 , a trajectory determination means 82 , and a position change means 84 .

When an event involving a change in viewpoint is started in the event management means 64, the start point determination means 80 determines the classification of the virtual camera position at the time the event is started. Details of the classification of the virtual camera position at the start of an event will be described later with reference to FIG. 7.

The trajectory determination means 82 determines a trajectory for changing the position of the virtual camera when the position of the virtual camera is changed by the viewpoint change means. In this embodiment, the trajectory determination means 82 determines the start of the virtual camera based on the basic trajectory and the position of the virtual camera at the start time of the event determined by the start point determination means 80.

The position changing means 84 changes the position of the virtual camera from an objective viewpoint to a subjective viewpoint or from a subjective viewpoint to an objective viewpoint when a predetermined condition is satisfied by the input information. Specifically, the position changing means 84 executes a process of changing the position of the virtual camera based on the trajectory determined by the trajectory determination means 82.
The game processing execution means 60 generates game images for each position of the virtual camera changed by the position change means 84 .

As shown in FIG. 3, the control unit 200 of the server 2 executes various programs and the like to cause the game information management means 220 to function.

The game information management means 220 of the server 2 manages various information required for the progress of the game by the game device 1 and executes various processes. Specifically, for example, the game information management means 220 executes authentication of the account information transmitted from the game device 1, distribution of game information in response to a download request of various game information from the game device 1, etc.

FIG. 4 is an image diagram showing an example of a trajectory along which the virtual camera moves in the viewpoint change process.
The example in Figure 4 shows an example of the movement trajectory of a virtual camera C1 when the virtual camera C1 is initially placed at position F1, passes through F2 and F3, and finally moves to position F4.
Here, the state where the virtual camera C1 is installed at the position F1 is a typical third-person viewpoint (objective viewpoint) situation. That is, for example, the viewpoint at the position F1 is the viewpoint of the virtual camera arranged based on the upper rear position of the operated character. Since the virtual camera is installed at a wide distance in the game image generated when the virtual camera C1 is installed at the position F1, it is possible to generate a wide game image with a bird's-eye view of the surrounding objects in the virtual space including the operated character of the player.
On the other hand, the state where the virtual camera C1 is set at F4 is a typical first-person viewpoint (subjective viewpoint) situation. That is, for example, the viewpoint at the position F4 is the viewpoint of the virtual camera placed based on the eye position of the playable character of the game. The game image generated with the virtual camera C1 set at the position F4 can generate a game image including only a limited situation close to the field of view of the player himself in the virtual space.
The state where the virtual camera C1 is set at F2 and F3 is an intermediate viewpoint state on the trajectory of the virtual camera C1 moving from the position of F1 to the position of F4. That is, the virtual camera C1 moves from F1 to F4 via F2 and F3, which are intermediate installation points on the predetermined trajectory.
The important point here is that the virtual camera C1 does not instantly move from position F1 to position F4, and that the virtual camera does not simply move from position F1 to position F4 along the shortest linear trajectory.
The trajectory of the virtual camera C1 in this embodiment moves from position F1 to a position behind the character on the left (right) side (e.g., near F2), passes through a position on the left (right) side of the character's head (e.g., near F3), and then moves in front of the character's eyes so that the character's face is not displayed, and then moves back to reach position F4. Note that Fig. 5 is a diagram showing the trajectory of the virtual camera C1 from a viewpoint above the character's head.

The reason why the virtual camera C1 of this embodiment deliberately adopts such a complex trajectory is to allow the viewpoint to be changed from a first-person viewpoint to a third-person viewpoint naturally while maintaining the worldview of the game. In other words, the virtual camera can be moved from an objective-point-of-view during a game to a subjective-point-of-view event along a comfortable trajectory seamlessly and without coming into contact with the character.

An example of a game image that is actually generated when the virtual camera C1 moves in this way is shown in Figure 6. Figure 6 shows an example of the transition of the game image displayed on the game device during the viewpoint change process.

An example of a game image generated from a typical third-person viewpoint (objective viewpoint) is shown in (a) of Fig. 6. For example, (a) of Fig. 6 is a game image generated in a state where a virtual camera C1 is set at the position F1 of Fig. 4.
Fig. 6B shows an example of a game image generated from a viewpoint from the left (right) rear of the character from position F1. For example, Fig. 6B shows a game image generated when virtual camera C1 is placed at position F2 in Fig. 4.
An example of a game image generated from a viewpoint from the left (right) side position of the character is displayed in (c) of Fig. 6. For example, (c) of Fig. 6 is a game image generated in a state where the virtual camera C1 is placed at the position F3 in Fig. 4.
An example of a game image generated from a typical first-person viewpoint (subjective viewpoint) is shown in (d) of Fig. 6. For example, (d) of Fig. 6 is a game image generated in a state where the virtual camera C1 is set at the position F4 in Fig. 4.
By adopting this type of trajectory, rather than simply changing the viewpoint by skipping time, the system can achieve a natural change of viewpoint during the game, avoiding the unnatural appearance of the controlled character and without compromising the player's sense of immersion in the game.

Next, the starting point of the viewpoint change process in this embodiment (hereinafter simply referred to as the "starting point") will be described with reference to FIG. 7. FIG. 7 is an image diagram for explaining the starting point in the viewpoint change process.

Here, the premise for the explanation of FIG. 7 will be explained. In this game, the player can freely perform various input operations for the playable character and the movement of the virtual camera in a third-person perspective during the game. Therefore, when the event management means 64 determines that the playable character has moved to a predetermined area in the virtual space, the virtual camera is not necessarily installed at the rear and upper part of the playable character, but may be installed, for example, at the front and upper part or the side of the character (however, all of these are third-person perspectives). In such a situation, if the typical trajectory shown in FIG. 4 to FIG. 6 is simply applied when changing the viewpoint, the player may feel uncomfortable when the virtual camera moves. Therefore, in this game, a specification is adopted that allows the trajectory when changing the viewpoint to be changed depending on the installation position (start point) of the virtual camera at the start of the event.

Specifically, in the example of Fig. 7, four virtual cameras are installed in the virtual space with the character P1 at the center, and the classification of four areas, area E1 to area E4, is displayed as the area in which each installed virtual camera exists. That is, Fig. 7 shows an example of a determination method when the start point determination means 80 determines the positional relationship of the virtual cameras at the start point. Note that, in the example of Fig. 7, the start point is classified based on the positional relationship in which the virtual cameras were installed in the planar direction (360 degrees) with the character P1 facing the direction of the arrow at the center. Specifically, for example, if the virtual camera C2 is installed at the position F5, the start point of the viewpoint change processing is area E1. Similarly, if the virtual camera C2 is installed at the point F7, the start point of the viewpoint change processing is area E3.
In the example of Fig. 7, the area E3 is set to be larger than the other areas. This is to set an area including the most basic installation position of the virtual camera introduced in Fig. 4 to Fig. 6. Therefore, the installation position of F1 in Fig. 4 to Fig. 6 is determined to be area E3, for example.
By adopting this concept, no matter what position the virtual camera is in at the start of the event, it can be moved comfortably to the final installation position.

Figure 8 is a flowchart that explains an example of the flow of processing related to viewpoint change processing among the processes executed by the server in Figure 3.

In step S1, the event management means 64 determines whether or not the playable character has moved to a predetermined area in the virtual space.
If the playable character has moved into the predetermined area, step S1 is determined as YES, and the process proceeds to step S2.
On the other hand, if the playable character has not moved into the predetermined area, step S1 is determined as NO, and the process of step S1 is repeated.

In step S2, the event management means 64 executes various processes to start an event involving a change of viewpoint when the playable character moves to a specified area in the virtual space.

In step S3, if an event involving a change in viewpoint is started in step S2, the start point determination means 80 determines the classification of the virtual camera position at the time the event is started. That is, in step S3, the start point determination means 80 determines the start point at the start of the event.

In step S4, the trajectory determination means 82 determines a trajectory for moving the virtual camera when changing the viewpoint, taking into account the starting point of the virtual camera determined in step S3.

In step S5, the position change means 84 executes a process to change the position of the virtual camera based on the trajectory determined in step S4. This ends the viewpoint change process.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and any modifications or improvements that can achieve the object of the present invention are included in the present invention.

<Other embodiments>

In the above embodiment, an example of the trajectory of the virtual camera C1 determined by the present system has been presented, but this is merely an example and is not limiting.
The system may adopt any other trajectory, including, for example, a linear trajectory, as the trajectory along which the virtual camera C1 moves.
Furthermore, the present system may determine the orbit taking into consideration, for example, the following aspects:
(1) It may follow a path that is similar to the line of sight movement of the operated character.
(2) Just before forming a first-person perspective, the virtual camera may be moved forward to a position where the playable character's face is not included in the game image, and framed out of the game image. (3) After the movement of (2), the playable character's face may not be displayed in the game image. (4) After the playable character's face is no longer displayed, the virtual camera may be moved backward again toward the eye position.
It should be noted that the system does not need to perform the above-mentioned movements at a uniform speed, and may slow down or speed up the movements of any process in order to reduce discomfort to the player.

Although not explained in the above embodiment, when moving from F1 to F4, the virtual camera C1 may stop once at the intermediate points F2 and F3, or may simply pass through F2 and F3 without stopping.

In the above embodiment (particularly FIG. 7), the present system has been described as dividing the planar area of the virtual space into four areas and determining the start point, but this is not limited thereto.
The system may divide the planar area in any other manner or distribution.
Furthermore, the present system may divide not only the planar area of the virtual space, but also the three-dimensional area including the vertical direction according to any criteria and use the divided areas to determine the starting point.

Although not described in the above embodiment (particularly FIG. 7), the present system may determine the start point from the following viewpoints, for example, and may take these into consideration when determining the trajectory.
(1) The system may compare the direction in which the playable character is currently facing with the direction in which the playable character should face in the event to be started, determine whether the playable character will turn sooner, facing right or facing left, and alter the trajectory determined by the virtual camera so that the playable character will turn in that direction.
(2) As described above, in this embodiment, the system is designed to pass through the side of the playable character's head (around the temple of the face). In this regard, the system may change whether the playable character passes to the right or left of the above-mentioned trajectory depending on the current orientation of the playable character at the start of the event.

Although not explained in the above embodiment, when changing the viewpoint, the present system does not simply move the installation position of the virtual camera along a predetermined trajectory, but may also change the positions and orientations of various objects (particularly the playable character) based on the start point of the event, the content of the event, etc.

In the above embodiment, the system was described as determining the trajectory for moving the virtual camera by taking into account the starting point of the virtual camera, but this is not limited to this.

Although not described in the above embodiment, the game may be executed by any hardware (e.g., game device 1, etc.), such as a home game console such as PlayStation (registered trademark), a portable game console such as Nintendo Switch (registered trademark), various game consoles designed for commercial use, or electronic devices such as a personal computer, smartphone, tablet, etc.

Although not explained in the above embodiment, the content of the game related to this system is not limited. This system may be applied to any game, such as FPS (First Person Shooter), TPS (Third Person Shooter), RPG (Role Playing Game), action game, simulation game, sports game, card game, battle royale (symmetric type, asymmetric type), MOBA (Multiplayer online battle arena), music game, fighting game, quiz game, etc.

Furthermore, the above-described series of processes can be executed by hardware or software.
In other words, the functional configurations in FIG. 3 and the like are merely examples and are not particularly limited.
That is, it is sufficient that the information processing system is provided with a function capable of executing the above-mentioned series of processes as a whole, and the type of functional block used to realize this function is not limited to the example in Fig. 3, etc. Furthermore, the location of the functional block is not limited to the example in Fig. 3, etc., and may be arbitrary.
Furthermore, one functional block may be configured as a single piece of hardware, may be configured as a single piece of software, or may be configured as a combination of both.

In addition, the number of different hardware components that make up this system and the number of users are optional, and the system may also be configured to include other hardware.

When a series of processes is executed by software, the programs that make up the software are installed on a computer or other device from a network or recording medium.

The computer may be a computer built into dedicated hardware, or a computer capable of executing various functions by installing various programs.
That is, for example, the various hardware in the above-described embodiment may be freely adopted as any computer, any mobile terminal such as a smartphone, any game machine, etc. Furthermore, any combination of types and contents of various input means and various output means may be adopted.

In addition, the recording medium containing such a program may be configured not only as a removable medium (not shown) provided separately from the device body in order to provide the program to the player, but also as a recording medium provided to the player in a state where it is already installed in the device body.

In this specification, the steps of writing a program to be recorded on a recording medium may be executed in parallel or individually, as well as in chronological order. Also, some of the steps described in the above embodiment may be omitted.

In addition, in this specification, the term "system" refers to an overall device that is composed of multiple devices, multiple means, etc.

Even when these other embodiments are adopted, the effects of this embodiment are achieved. In addition, this embodiment can be combined with other embodiments, and other embodiments can be combined with each other as appropriate.
