[Figure 3] FIG. 2 is a diagram illustrating an example of image data for recording. DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0010] 1 is a block diagram showing the configuration of an image generation device 10 according to one embodiment of the present invention. Image generation device 10 is, for example, a home game console, a portable game console, a personal computer, or the like, and as shown in the figure, is configured to include a control unit 11, a storage unit 12, and an interface unit 13. Image generation device 10 is also connected to a display device 14 and an operation device 15.

[0011] The control unit 11 includes at least one processor such as a CPU, and performs various information processing by executing programs stored in the storage unit 12. Specific examples of the processing performed by the control unit 11 in this embodiment will be described later. The storage unit 12 includes at least one memory device such as a RAM, and stores the programs executed by the control unit 11 and data processed by the programs.

[0012] The interface unit 13 is an interface for data communication between the display device 14 and the operation device 15. The image generation device 10 is connected to each of the display device 14 and the operation device 15 via the interface unit 13 either wired or wirelessly. Specifically, the interface unit 13 includes a multimedia interface for transmitting a video signal supplied by the image generation device 10 to the display device 14. It also includes a data communication interface for receiving a signal indicating the operation content performed by the user on the operation device 15. Furthermore, the interface unit 13 may include a communication interface for transmitting and receiving data to and from other communication devices via a communication network such as the Internet.

[0013] Display device 14 displays on a screen an image corresponding to the video signal supplied from image generation device 10. Display device 14 may be a stationary display device such as a home television receiver, or may be a portable display device. Display device 14 may also be a head-mounted display device capable of presenting a stereoscopic image by presenting separate images to the left and right eyes of the user.

[0014] The operation device 15 is, for example, a controller for a home game console, and receives operation input from a user. The operation device 15 is connected to the image generation apparatus 10 by wire or wirelessly, and transmits an operation signal indicating the content of the operation input received from the user to the image generation apparatus 10. The operation device 15 may be of various shapes, such as a device that the user holds in their hand or a device that the user wears on their hand.

[0015] The functions realized by the image generating device 10 will be described below with reference to the functional block diagram of FIG. 2. As shown in FIG. 2, the image generating device 10 is functionally configured to include a scene information generating unit 21, a display image generating unit 22, and a recording image generating unit 23. These functions are realized by the control unit 11 operating in accordance with one or more programs stored in the storage unit 12. These programs may be provided to the image generating device 10 via a communication network such as the Internet, or may be provided by being stored on a computer-readable information storage medium such as an optical disc.

[0016] The scene information generation unit 21 determines the content of a scene to be presented to the user and generates scene information for specifying that content. The scene information generation unit 21 may be realized by an application program such as a game program, for example.

[0017] In this embodiment, the scene to be presented to the user is assumed to be the interior of a virtual three-dimensional space (virtual space). In this case, the scene information generating unit 21 determines, as scene information, information for specifying the shape and appearance of an object to be placed in the virtual space, its position within the virtual space, and the like.

[0018] Furthermore, the scene information generation unit 21 also determines information that identifies the portion of the scene defined by the scene information that is actually to be displayed. Specifically, the scene information generation unit 21 determines the viewpoint position and viewing direction to be set in the virtual space in response to instructions from the user, etc. Furthermore, if the display device 14 is a type that is worn on the user's head, the scene information generation unit 21 may determine the viewing direction so as to be linked to the orientation of the user's face. In this case, viewing direction information that indicates the orientation of the user's face can be obtained by various methods, such as using the detection results of an orientation sensor built into the display device 14.

[0019] Furthermore, when presenting the user with not only the state of the virtual space but also other information, the scene information generation unit 21 determines a display object representing that content and its placement position. For example, in a game, content such as information about the current play situation, character information, map information, etc. may be superimposed on the state of the virtual space and displayed on the screen of the display device 14. It is desirable that such information be displayed at a predetermined position on the screen regardless of the state of the virtual space, the viewpoint position, etc. Hereinafter, an object representing the content of such information is referred to as an information object. The scene information generation unit 21 determines the content of information to be included in this information object and its display position on the screen, and includes it in the scene information.

[0020] The display image generating unit 22 references the scene information generated by the scene information generating unit 21 and generates image data relating to the scene represented by the scene information, using the display image data ID. Here, the display image generating unit 22 generates the display image data ID based on a predetermined first image generation parameter. The display image generating unit 22 may be realized by a program such as a rendering engine separate from the application program that realizes the scene information generating unit 21.

[0021] Specifically, the display image generation unit 22 generates, as display image data ID, an image representing the virtual space in which various objects included in the scene information are arranged, as viewed from the viewpoint position and viewing direction specified by the scene information generation unit 21. Since the entire virtual space cannot be displayed on the screen of the display device 14 at once, this display image data ID becomes image data representing a portion of the scene (the state of the virtual three-dimensional space) represented by the scene information provided by the scene information generation unit 21. Furthermore, the display image generation unit 22 generates the display image data ID by superimposing the contents of the information objects included in the scene information on the drawing contents of the virtual space as necessary.

[0022] When the display device 14 realizes stereoscopic vision using parallax, images are presented to the right and left eyes of the user, and therefore the display image generation unit 22 generates an image for the right eye and an image for the left eye. For the sake of convenience, the following description focuses on only one of the images, but the image generation device 10 may perform the same processing on both the image for the right eye and the image for the left eye.

[0023] The display image generation unit 22 transmits a video signal including the generated display image data ID to the display device 14. As a result, the display image is displayed on the screen of the display device 14 and presented to the user. The image generation device 10 according to this embodiment repeatedly executes the process of generating scene information by the scene information generation unit 21, the process of generating display image data ID by the display image generation unit 22, and the process of transmitting the display image data ID to the display device 14 at a given frame rate, thereby causing the display device 14 to display an image showing the state of the virtual space that changes over time.

[0024] Here, the first image generation parameters used when generating the display image data ID include parameters for defining the area to be displayed within the scene defined by the scene information. As described above, in this embodiment, information on the viewpoint position and the viewing direction is used to define the area to be displayed.

[0025] Furthermore, the first image generation parameters may include parameters determined according to the display performance of the display device 14. As a specific example, the resolution of the display image data ID is determined according to the resolution and size of an image that the display device 14 can display. For example, when a new display device 14 is connected, the display image generation unit 22 acquires information about the display performance of the display device 14 (such as information about the size of an image that can be displayed), and determines the resolution when generating the display image data ID according to the acquired information. Furthermore, parameters for defining an area within a scene included in the display image data ID (such as the viewing angle) may also be determined according to the display performance of the display device 14.

[0026] The recording image generation unit 23 references the scene information generated by the scene information generation unit 21 and generates image data relating to the scene represented by the scene information as recording image data IR. Here, the recording image generation unit 23 references the same scene information as the scene information referenced by the display image generation unit 22 when generating the display image data ID, and generates the recording image data IR based on second image generation parameters that are different from the first image generation parameters used to generate the display image data ID. Specific examples of these second image generation parameters will be described later.

[0027] The process of generating the recording image data IR by the recording image generating unit 23 may be the same as the process of generating the display image data ID by the display image generating unit 22, except for the parameters used for generation. Furthermore, the recording image generating unit 23 may execute a process of generating the recording image data IR in parallel based on the same scene information while the display image generating unit 22 executes a process of generating the display image data ID.

[0028] The recording image generation unit 23 may generate and save one piece of recording image data IR based on a user instruction or the like. As a specific example, when a user instructs the operation device 15 to take a screenshot by operating the operation device 15, the recording image generation unit 23 generates recording image data IR as a single still image by referencing the scene information used to generate the display image data ID at that timing. This recording image data IR targets the same scene as the display image data ID, but is generated based on different image generation parameters, and therefore is different image data from the display image data ID. Hereinafter, recording image data IR generated independently in this way will be referred to as recording still image data.

[0029] The recording image generating unit 23 may also generate multiple recording image data IR corresponding to multiple display image data IDs generated in chronological order. In this case, the recording image generating unit 23 starts the process of generating the recording image data IR based on a user instruction to start recording, etc. Then, until the process of generating the recording image data IR is terminated by the user's instruction to end recording, etc., each time the display image generating unit 22 generates one piece of display image data ID, it generates one piece of recording image data IR using the scene information used to generate that display image data ID. By repeatedly performing this process over a predetermined period of time, the recording image generating unit 23 generates the same number of recording image data IR for the same scene as the display image data ID displayed on the display device 14 during this period.

[0030] In this case, the recording image generation unit 23 saves, as recording video data, data consisting of multiple pieces of recording image data IR generated in chronological order over the period to be recorded. Note that the recording video data may be data containing multiple pieces of recording image data IR in their original format, or may be data encoded using a given video encoding method. In the following, the recording still image data and / or recording video data to be saved by the image generation device 10 will be collectively referred to as recording content data.

[0031] The user of the image generating device 10 can upload the recorded content data saved by the record image generating unit 23 to a predetermined server device or distribute it in response to requests from other users, thereby making it available to others. The user may also edit the contents of the recorded still image data or recorded video data by themselves before making it available to third parties.

[0032] Hereinafter, several specific examples of the process in which the recording image generating unit 23 generates the recording image data IR based on the second image generation parameters will be described.

[0033] As a first example, the recording image generation unit 23 may generate the recording image data IR at a different resolution than the display image data ID. More specifically, the recording image generation unit 23 may generate the recording image data IR so that it has a higher resolution than the display image data ID. As described above, the display image generation unit 22 generates the display image data ID at a resolution determined according to the display performance of the display device 14. However, the recording image data IR may be displayed on a display device with a higher resolution than the display device 14, and the resolution does not necessarily need to match the display performance of the display device 14. Therefore, the recording image generation unit 23 may generate recording image data IR at a higher resolution than the display image data ID, targeting the same area as the display image data ID.

[0034] In particular, when saving one piece of recording image data IR as recording still image data, the processing load required for rendering processing and the data capacity required for saving are smaller than those for video data, so the recording image generation unit 23 can generate and save the recording image data IR with a relatively large margin. However, the recording image generation unit 23 is not limited to saving recording still image data; even when saving recording video data, the recording image generation unit 23 may generate multiple pieces of recording image data IR that make up this recording video data at a higher resolution than the display image data ID.

[0035] Furthermore, the recording image generating unit 23 may generate the recording image data IR using parameters for the color space and bit depth when generating the image that are different from those used when generating the display image data ID.

[0036] As a second example, the recording image generation unit 23 may generate the recording image data IR for an area of ​​the scene defined by the scene information that is different in size from the area included in the display image data ID. Specifically, for example, the recording image generation unit 23 generates the recording image data IR for an area that includes the contents of the display image data ID and is larger than the display image data ID. This makes the data size of the recording image data IR larger than the display image data ID, but makes it possible to save recording content data that also includes the state of the area outside the range displayed on the screen of the display device 14.

[0037] As a third example, the recording image generation unit 23 may generate recording image data IR that shows the virtual space viewed from a viewing direction different from the viewing direction used when generating the display image data ID. In this case, as in the second example, recording image data IR is generated that targets an area different from the area included in the display image data ID. For example, the recording image generation unit 23 determines a new viewing direction based on the viewing direction used when generating the display image data ID as part of the second image generation parameters, and generates recording image data IR that shows the virtual space viewed from this new viewing direction. As a specific example, the recording image generation unit 23 generates the recording image data IR using viewing direction parameters that shift the viewing direction used when generating the display image data ID by a predetermined angle in a predetermined direction (e.g., left or right). Alternatively, the recording image data IR may be generated with a viewing direction opposite to the viewing direction used when generating the display image data ID.

[0038] According to this method, it is possible to generate record content data that indicates the status of a location in the virtual space that is not included in the display image data ID (i.e., not viewed by the user viewing the display device 14). For example, by generating and saving such record image data IR at the timing when the user gives an instruction to capture a scene in the opposite direction, the user can later check the scene outside the game screen that they were viewing. Note that the record image generation unit 23 may generate record image data IR for each of a plurality of viewing directions that are determined based on the viewing direction used to generate the display image data ID.

[0039] As a fourth example, the recording image generation unit 23 may determine the position of an area to be included in the recording image data IR according to the position of a predetermined object in the virtual space included in the scene information. Like the second and third examples, this example is also an example of generating recording image data IR for an area different from the display image data ID, but unlike the previous examples, the position of the area to be included in the recording image data IR is determined based on information about an object included in the scene information.

[0040] Specifically, the recording image generation unit 23 determines an area to be included in the recording image data IR based on the position of the target object T. The target object T in this example may be, for example, a character object that the user operates, an object that the user is expected to pay particular attention to (for example, an enemy object that the user attacks), or an object specified by the scene information generation unit 21.

[0041] For example, the recording image generation unit 23 determines the position of the area to be included in the recording image data IR so that the specified object of attention T is positioned at the center of the recording image data IR. This makes it possible to save recording content data that allows the object of attention T and its surroundings to be confirmed. Particularly when playing a game, the user may change the direction of view to check the surroundings and cause the display device 14 to display a position away from the object of attention T. Even in such cases, by generating recording image data IR that includes an area based on the object of attention T separately from the display image data ID, it is possible to save recording content data that makes it easy to confirm the state of the object of attention T.

[0042] Furthermore, the recording image generation unit 23 may generate the recording image data IR by extracting the object of interest T and its surrounding area from the display image data ID. As a specific example, the recording image generation unit 23 generates the recording image data IR by extracting the object of interest T and its surrounding area of ​​a predetermined size from the display image data ID. This makes it possible to easily create recording still image data or recording video data that focuses only on a specific object (such as a character object operated by the user).

[0043] The extraction size in this example may be determined according to a specification from the scene information generation unit 21, or may be determined according to a content previously set by the user. For example, the scene information generation unit 21 specifies the size of the extraction target region centered on the target object T, taking into account the size and movement speed of the target object T itself.

[0044] Furthermore, when the scene information includes multiple target objects T, the recording image generation unit 23 may generate multiple recording image data IR for each of the target objects T. Fig. 3 is a diagram showing a specific example of generating multiple recording image data IR in this manner. In the example shown in this figure, two target objects T, T1 and T2, are included in the display image data ID, and two recording image data IR1 and IR2 are generated for each of the target objects T.

[0045] As a fifth example, when a scene to be displayed for display image data ID is composed of multiple types of objects, the recording image generation unit 23 may generate recording image data IR composed of some of the types of objects. In this example, the scene to be rendered is assumed to be composed of multiple types of objects, and objects of the same type belong to the same layer. The display image generation unit 22 generates image data in which multiple layers are superimposed as display image data ID.

[0046] As a specific example, as described above, the display image generation unit 22 generates display image data ID by rendering a spatial image showing an object in a virtual space as viewed from a given viewpoint as a single layer image and overlaying a layer image representing the contents of an information object on this layer image. In this case, the record image generation unit 23 independently renders the layer image representing the state in the virtual space and the layer image representing the contents of the information object, and saves each of them as record image data IR. Alternatively, the record image generation unit 23 may generate only the layer image representing the state in the virtual space as record image data IR. If an information object contains information such as a character's status, such information must be visible during game play, but may interfere with the display of the gameplay when viewing the gameplay later. Therefore, by generating an image excluding the contents of the information object as record image data IR, an image without the information object can be viewed later.

[0047] Furthermore, various types of objects may be included among the objects placed in the same virtual space. For example, it is common for background objects, whose positions within the virtual space do not change, and character objects, whose positions within the space move as the game progresses, to be included in the same scene. The display image generation unit 22 generates display image data ID that includes all of these objects. In contrast, the recording image generation unit 23 may generate recording image data IR by drawing these objects separately by type. This allows the background layer image, character layer image, etc. to be generated and saved individually as recording image data IR.

[0048] As described above, the recording image data IR generated for each type of object based on the same scene may be displayed individually later, or may be composited together and displayed. For example, by displaying recording image data IR containing a character object individually, the user can later view a video focusing on the character's movements. Also, by overlaying multiple recording image data IR generated at the same time for the same scene, the user can later view an image similar to the display image data ID the user was viewing when the recording image data IR were recorded.

[0049] The recording image generating unit 23 may generate the recording image data IR by combining the methods described above. For example, the recording image generating unit 23 may generate recording image data IR with a higher resolution than the display image data ID, targeting an area different from the display image data ID.

[0050] Furthermore, the recording image generation unit 23 may include, in the recording content data, related information acquired when generating the recording image data IR along with the recording image data IR. For example, the recording image generation unit 23 may include, in the recording content data, information indicating the position of the target object T used to generate the recording image data IR, information on the viewpoint position and the viewing direction, etc. Furthermore, the recording content data may include, in the recording content data, information indicating the operation content performed by the user on the operation device 15 when the display image data ID is displayed. This information can be used later when the user displays or edits the contents of the recording content data.

[0051] As described above, according to the image generating device 10 of this embodiment, when generating display image data ID, recording image data IR representing the same scene is generated in parallel based on image generation parameters different from the display image data ID, thereby making it easier for other users to view the scene later.

[0052] It should be noted that the embodiments of the present invention are not limited to those described above. For example, in the above description, the scene information generated by the scene information generation unit 21 represents an appearance in a three-dimensional virtual space, and the display image data ID is an image representing the appearance in the three-dimensional virtual space. However, this is not limiting, and the scene information generated by the scene information generation unit 21 may represent the contents of a two-dimensional scene. Even in such a case, when display image data ID including multiple objects constituting the scene is generated, the recording image generation unit 23 may generate recording image data IR based on second image generation parameters different from the first image generation parameters used to generate the display image data ID.

[0053] In the above description, the image generation device 10 is an information processing device located relatively close to the user and directly connected to the display device 14 and the operation device 15. However, this is not limited to this. For example, in services such as cloud gaming services, a server device connected to the client device via a communication network may generate images to be displayed on the screen of the display device 14, rather than a client device directly connected to the display device 14 and the operation device 15 used by the user. In such cases, the server device connected to the client device used by the user via a communication network may function as the image generation device 10 of the present invention. In this case, operation information for the operation device 15 acquired by the client device is transmitted to the image generation device 10 via the communication network. The image generation device 10 generates display image data ID based on the received information and transmits it to the client device. The client device then displays the received display image data ID on the screen of the display device 14. Meanwhile, as described above, the image generation device 10 generates record image data IR along with the display image data ID. The generated record image data IR may be stored in the image generation device 10 itself, or may be transmitted to the client device and stored therein.
