1379699 VI. Description of the Invention: [Technical Field] The present invention relates to an imaging device, an image generating method, a recording medium, and a program, even in the presence of an obstacle. [Prior Art] In the prior art, an action game or a role-playing game in which a game for home or business (such as a video game device) can enjoy a three-dimensional display is developed. In such a three-dimensional display action game, for example, a virtual camera that is a viewpoint is used to display the image of the main character and the beta (viewing). In addition to the protagonist in the virtual space, because there are also various ^ ~- ί / / Ί ,, so other objects are located between the main character and the camera. For example, when a wooden object is located between the main character and the camera, the tree object == obstacle of the line of sight of the camera.勹 勹 摄 摄 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在In the case of the problem of the defect, the technique disclosed is to improve the transparency of the obstacle when the main character is covered, and to become the main character of the object (for example, Japanese Patent Laid-Open No. 42370). 】 ° 098108211 4 (Problem to be solved by the invention) In the case of the above-mentioned mode, when QA _ has any event, (4), the action game, etc., for example, when the shot is taken as the viewpoint, when the main character is noticed, From the filming machine at that time, the shooting action for the positioning of the camera in the position of the camera: the main camera () is used to zoom in or out, and the show is displayed in the show. image. All are important, ,::::, the bow shows the player’s attention to the performance image. Therefore, the second is not the main target of the subject being obscured by the obstacle. The other readings* are limited to the situation where the obstacles are not present around the main character (for example, 'there are no wide buildings with buildings or trees'), such as the use of such a camera. The requirement is to use a show camera in the presence of such obstacles in a game that increases the game (burst or condition, etc.) according to the player's method of execution. To satisfy such a requirement# Example h 'Consider 'Check if there is an obstacle present before shooting with a show camera'. When there is an obstacle, make the show camera closer to (moving to) the main character side than the obstacle, and read the obstacle. Photographing. However, when the performance camera is simply moved to the main character side of the obstacle, the position of the obstacle will cause the performance camera to be too close to the main character. In this case, the main character is displayed more than necessary. (too big), the task of performing a camera cannot be fully fulfilled. 098108211 1379699 . Therefore, it is required to consider obstacles and use The technique of photography photography. 乂 田 地 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Means for Solving the Problem: The image generation device of the first aspect of the invention uses a camera device to generate a game device that is placed in a virtual (four) color:= image, and a gift of "A Shishiyue binding" The photographing position is $_立" 〇3 object position memory unit, camera, and image generating unit. 〜Hb camera control unit first, the object position recording unit 4 is positioned in the space. The object of the main character is In the same direction, the position character memory of the eye-catching character is used to store the positions of a plurality of cameras that are arranged without the camera. The position of the obstacle is determined according to the position of each camera and the object of each object. Whether there is an object that obscures the obstacle between each camera and the character of the eye. The camera selects the camera that is judged to be a camera without obstacles. The camera control unit is selected. The movie is a photographic action for the performance of the zoom or pan, etc. Then, the image produced by the camera controlled by the camera is generated by the student. = 'Use a camera that shoots from different directions, from Among them, the camera that is not photographed by the _ object _ can be photographed and photographed 098108211. Therefore, even in the presence of an obstacle, the character can be photographed. If there is an obstacle, In the case where the obstacle determination unit determines that there is an obstacle to the camera of the king, the target selection and the obstacle are selected. The distance is the farthest camera; and the camera control unit moves the selected camera to the attention character side of the obstacle, for example, for performing a shooting operation for the performance. In this case, even if all the cameras are obscured by obstacles, the camera that moves the farthest from the obstacle is moved to the front of the obstacle (the obstacle is highlighted by the viewpoint). The character takes the position of photography) and performs photography. Therefore, the camera does not get too close to the target character, but can produce an appropriate image. The camera control unit may, for example, cause the obstacle determination unit to sequentially determine whether or not there is an obstacle between the camera and the attention character in the shadow shooting after the start of the shooting operation for the performance; and determine that there is an obstacle, and When the distance between the attention character and the obstacle is equal to or greater than the reference value, the camera control unit continues the imaging operation for the performance, for example, after moving the camera to the attention character side of the obstacle. In this case, after the selected camera starts the shooting operation, even if a situation is blocked by the new obstacle, the camera can be moved to the obstacle 098108211 7 the obstacle is just behind the surface (the viewpoint highlights the obstacle and can be The attention character performs the shooting position) and continues the shooting operation. Therefore, it is possible to continue to produce an appropriate image. / After the camera control unit starts the shooting operation for the performance, the obstacles may be made to have obstacles between the camera and the character in question; and the camera and the eye in the shadow photography are determined. When the distance between the character and the obstacle is shorter than the reference value, the camera selection unit selects one of the cameras that are not obstructed, and determines that there is no obstacle. The other camera of the object selects any one of the cameras; and the camera control unit controls the reselected camera, for example, to continue the shooting operation for the performance. In this case, after the selected camera starts the shooting operation, even if a new (four) obstacle (a obstacle close to the attention character) is generated, the camera can be re-arted and switched to another camera. You can continue to produce the appropriate image. The image generating method according to the second aspect of the present invention is a video generating device having a memory unit, an arithmetic unit, and a material unit, and is a virtual camera of a viewpoint to generate an image for photographing a character placed in the virtual space. The memory unit includes a position of a plurality of objects of the attention character in the virtual space 7 and a position of a plurality of cameras 098108211 I37S699 that are used to record the attention characters from different directions, and the configuration includes an obstacle determination. Steps, camera selection #steps, camera control steps, and image generation steps. In the obstacle determination step, based on the position of each camera and the position of each object stored in the memory unit, it is determined whether or not there is an object that obstructs an obstacle between each of the camera and the character. In the camera selection step, one of the cameras is selected from a camera that is judged to be free of obstacles. In the camera control step, the selected camera is controlled, for example, to perform a shooting action for the performance. In the image generation step, an image captured by the controlled camera is generated. In other words, a camera that photographs from different directions is used, and a camera that can be photographed by an eye-catching character that is not obscured by an obstacle is selected and photographed, so that even in the presence of an obstacle, it becomes an attractive character. Take photography. As a result, even in the presence of an obstacle, it is possible to produce an image that is appropriately photographed for the attention/character. The information recording medium of the third aspect of the present invention stores a program for causing a computer (including an electronic device) to function as the server. The program of the fourth aspect of the present invention is constructed such that a computer (including an electronic device) has a function as the image generating device described above. - The program can record computer-readable information recording media such as CD-ROM, floppy disk, hard disk, magneto-optical disk, digital video disk, tape and semiconductor memory. 098108211 9 The program can be used with the computer. The road is scattered and sold. Μ & Spreading H independently through the computer brain, the reading medium can be combined with the electric (invention effect) $this hair material.

Further, in addition to the game device 100 of the present embodiment, a computer (a general-purpose personal computer or the like) such as a 098108211 1379699 may be used as the image generating device. For example, a general computer includes a CPU, a RAM, a ROM, a DVD-ROM drive, and an NIC, and a video processing unit having a function that is simpler than the game device 100, and has a hard disk as an external memory device. In addition to this, you can use floppy disks, magneto-optical disks, tapes, and more. Alternatively, instead of using a controller, a keyboard, a mouse, or the like may be used as the input device. Further, after the game program is installed, when the program is executed, it can function as an image generating device. (Summary structure of image generating device) Fig. 2 is a schematic view showing a schematic configuration of the image generating device of the embodiment. An example of the image generating device is an action game or a role-playing game in a three-dimensional display. When a predetermined event occurs, and the main character is noticed, the virtual camera that becomes the viewpoint at the time is switched to the performance camera (performance) With the virtual camera), the shooting action for the performance of the eye-catching character (the main character that will be noticed) is enlarged or panned. This will be described below with reference to the figure. As shown in the figure, the image generating apparatus 200 is configured to include an object information characterization unit 21, an operation accepting unit 220, an object position managing unit 23, a camera position control unit 240, an obstacle reading, and a camera list selection. The unit 270, the camera control unit, the camera, and the video rendering unit 290. m ° has been implicitly placed in the virtual space of the protagonist (playing role), enemy characters, tree too month wood stone and buildings and other objects 098108211 137:9699 information. Specifically, for each object, the memory is called information or texture information. The M 103 or the like has a function as the object information storage unit 210. 7 The operation accepting unit 220 also inputs an operation instruction such as an operation main character. For example, in the life-saving, ☆ search in the fine X department 220, the player presses and moves in the given direction, using the sword weapon (shooting, swinging the sword), picking up, squatting, squatting, etc.

For the corresponding eve of the eve (the instance is configured in the direction of the controller (10), A, B, X: | a, y know, a, , temple), used to accept the protagonist Operation Input 0 The controller 105 has a function as such an operation accepting unit 220. The object position management unit 230 is for managing the position information (current position, direction, etc.) of the object in the virtualized position in the virtual work room of the lead character or the enemy character. For example, the main character changes the position or direction in the virtual work room according to the movement instruction accepted by the operation and text management unit 220, and therefore the position information is managed by the object position management unit (10). In addition, the enemy character moves the 'and changes the position in the virtual (4), etc. appropriately according to the established logic, so the position information is managed in the same manner. Further, the object position management unit 23 also manages position information of objects such as buildings, trees, rocks, and the like that are not in the virtual space. Further, the RAM 103 and the CPU 1〇1 have functions as such an object position management unit 230. The camera position management unit 240 memorizes the position of the performance camera of a plurality of 098108211 15 1379699 facing the main character from different directions. Specifically, as shown in Fig. 3, the camera position management unit 240 manages the position information of the three performance cameras EC1 to EC3 disposed before the main character SC. In addition, the direction (the photographing direction) of each of the show cameras E (n to EC3) is managed so as to face the main character SC at the time of photographing. In addition, in FIG. 3, it can be easily illustrated, and the top view of the main character SC of the virtual space is seen from above. The following figures are also appropriately described in such a plan view. The position information of the performance cameras EC1 to EC3 may be an absolute position determined according to an event, or may be a relative position determined according to the position of the main character SC. An example is when a special weapon is picked up (acquired) by the main character, and when an event occurs, three positions facing the initial position (position, etc.) of the weapon are determined, respectively. An example is when the event occurs in a predetermined period of time (for example, an explosion of a time bomb installed, etc.), at a predetermined distance from the position facing the current position of the main character, etc. In addition, the RAM 103 and the CPU 101 There is a function as such a camera position management unit 240. Returning to Fig. 2, the obstacle determination unit 250 memorizes according to the object position management unit 230. The position information of each object and the position information of each of the performance cameras stored in the camera position management unit 240 determine whether or not the obstacle between the respective camera and the main character is blocked. 098108211 16 1379699 That is, the obstacle determination unit 250' is as shown in the figure. As shown in FIG. 4A, it is determined whether or not there is an object that becomes an obstacle on the line of sight VL from the show camera EC (EC CD EC3) toward the main character SC. Further, the 'obstacle determination unit 250 may be as shown in FIG. 4B. For the performance of the movie, the camera EC is used as the base point, and it is determined whether or not there is an object on each of the auxiliary line of sight jjL by using the auxiliary line of sight HL which forms a predetermined angle of 0 with the line of sight VL. Further, in Fig. 4β, it is easy to In the same way, the auxiliary line of sight HL is enlarged in the vertical direction. In this way, the auxiliary line of sight HL is also expanded in the vertical direction. It is also possible to discriminate a part of the obstacles, etc. The CPU 101 has a function as such an obstacle discriminating unit 25〇. The camera list 260 stores the information of the show camera that is determined to be free of obstacles by the obstacle discriminating unit 25. As shown by Lu Ru® I 5A, there is a visual line that obscures the performance of the multi-camera EC2. In the case (when the line of sight VU, VL3 is not obscured), in the camera list 260, as shown in FIG. 5B, the performance camera Eci and ECk information are stored. # That is, in the camera list 26G, the storage is not blocked by the obstacle. In addition, the GUI 103 has a function as such a camera list 260. Returning to Fig. 2, the camera selection unit 270 selects from the camera list 098108211 17 1379699 in the show camera 'for example, randomly selected 1 camera. That is, any one of the cameras that are judged to be free of obstacles is selected. In addition, there is also information that indicates that there is an obstacle in all the cameras of the show and that there is no one stored in the camera list 260. In this case, the camera selecting unit 270 selects the performance camera corresponding to the farthest distance from the main character and the obstacle.

For example, as shown in Fig. 6A, the visual lines VL1 to VL3 of all the performance cameras Eci to EC3 are blocked by the obstacles SB1 to SB3, respectively. In this case, the camera selecting unit 270 obtains the distance d1 between the main character SC and the obstacle SB1, the distance d2 between the main character SC and the obstacle SB2, and the distance d3 between the main character SC and the obstacle SB3, respectively, as shown in Fig. 6B. . Then, the performance camera EC3 corresponding to the distance d3 which becomes the maximum (distal) distance is selected. In addition, there are also multiple obstacles on the line of sight of the show camera.

It's a condition. In this case, the distance from the obstacle close to the main character is obtained as an object. Further, the CPU 101 has a function as such a camera selecting unit 27A. Referring back to Fig. 2, the camera control unit 28 controls the selected performance camera to perform a shooting operation for the performance. Perform an image of the protagonist's action of the show, such as zooming in, panning, and shaking. For example, the camera control unit 28 uses the photographing operation to pay attention to the player. When it is determined that there is an obstacle to all the cameras, the above-described selection is used. P 270 Selects the distance between the main character and the obstacle as the farthest shot. 098108211 18 137.9699 When the camera control unit 28Q moves the selected camera to the main character side of the obstacle, the shooting action for the performance is performed. . For example, as shown in Fig. 7A, in the state where the show camera EC bu EC3 is obscured by the obstacle SB1 SB3, the camera camera which is the farthest distance is selected. In this case, as shown in FIG. 7B, the camera control unit 280 moves the position of the show camera (10) to a substantial viewpoint (the lens portion in the figure) to highlight the obstacle = 3 and can photograph the main character sc. The performance of the performance is also 'not obscured by the obstacle SB3, and the performance camera is moved to a position where it can be as far as possible from the main character. Then, the action is started from the *Hai moving position. The CPU 101 has a function as such a camera control unit 280. Image tracing _9G According to the information of the object information memory department, the information of the object and the position of the object management department of the object management department S' to the object in the virtual space (inside the horizon), depicting the usual virtual machine Or a performance camera controlled by the camera control unit as a game image of the viewpoint. When a predetermined camera is selected by the above-described camera selecting unit, the video rendering unit 29 draws the two cameras controlled by the camera (four) as the viewpoint image. Moving Large Camera (4) (4) Department 28Q Chi Huan Yun (4) Photography When the virtual camera EC is viewed, as shown in Figure 8A, it becomes 098108211 1379699 moving from position X to position Y. Therefore, as shown in FIG. 8B, the video image capturing unit 290 draws the game image captured by the show camera EC at the position X, and then expands the main character SC as the show camera EC moves from the position X to the position (. Zoom in), and soon, as shown in FIG. 8C, the game image captured by the show camera EC at the position is depicted. When the performance of the performance is panning or shaking, the video rendering unit 290 draws an image in accordance with the position and direction (view position or line of sight) of the performance camera in the same manner as described above. Further, the video processing unit 108 has a function as such a video rendering unit 290. (Operation of Image Generating Apparatus) Fig. 9 is a flowchart showing the flow of image generating processing carried out in the image generating apparatus 200 of the above configuration. The operation of the image generating apparatus 200 will be described below with reference to the drawing. The image generation processing is performed, for example, in the execution of the game, and the event processing is performed first when the predetermined event occurrence condition is satisfied. In addition, at the beginning of the image generation process, the camera list 260 is cleared (without any registration). In the game, when a predetermined event occurrence condition is satisfied, first, the image generating apparatus 200 sets the position of the performance camera (step S301). That is, the camera position management unit 240 sets the positions of the plurality of show cameras facing the main characters from the different three directions. That is, as shown in Fig. 3 described above, the position information of each of the show cameras EC1 to EC3 facing the main character is set and managed by the camera 098108211 20 1379699 position management unit 240. Further, the positions of the performance cameras EC1 to EC3 may be absolute positions determined in accordance with events, or may be relative positions determined in accordance with the position of the main character SC. - The image generating device 200 determines whether or not each of the show cameras is obscured. The obstacle between the main characters is placed in the camera list 260 (step S302). In other words, the obstacle determination unit 250 determines whether or not there is a shadow toward each of the main characters based on the position information of each object stored in the object position management unit 230 and the position information of each of the performance cameras recorded by the camera position management unit 240. An obstacle to the sight of the camera. Then, the obstacle discriminating unit 250 determines that the information of the show camera without the obstacle is stored in the camera list 260. That is, the camera list 260 stores information of the show camera that is not obscured by the obstacle and can be photographed to the main character. In addition, when it is determined that all of the performance cameras are obscured by obstacles, it becomes not stored in the camera list 260. Information of any of the performance cameras. The video generating device 200 determines whether or not the information of the show camera is registered in the camera list 260 (step S303). In other words, whether or not the information of the show camera that can be photographed by the main character without being obscured by the obstacle is stored in the camera list 260 is one or more. When the image generating apparatus 200 determines that the information of the show camera is registered in the camera list 260 (step S303; Yes), the process proceeds to step S305 described later in 098108211 1379699. On the other hand, when it is determined that the information of the show camera is not registered (step (4) L image generating device seeks the distance between the main character and each obstacle (step S3G4). That is, since all the cameras of the show are obstructed, the image is generated. The device 2GG, as shown in Fig. 6β above, obtains the distance μ between the principal angle SC and the obstacle SB1, the distance d2 between the principal angle sc and the obstacle SB2, and the distance d3 between the principal angle SC and the obstacle SB3. Image generating device 2〇演出Select one of the show cameras (step S3〇5). First, when the information of the show camera is registered in the camera list 260, the camera select unit 27G randomly selects i show scenes from the list: In other words, one of the show cameras is selected from the camera that is determined to have no obstacles. When only one of the camera lists is registered, the show camera is automatically selected. In addition, when the camera list 260 is not When the information of the show camera is registered, the camera selecting unit 270 is from the distance (the distance between the main character and each obstacle) obtained in step S304. The performance camera corresponding to the largest (far) person is selected. For example, in the case shown in Fig. 7A described above, the performance camera EC3 that is shielded by the obstacle SB3 farthest from the main character is selected. The image generation device 200 performs the performance on the performance camera. The photographing operation generates a game image captured by the performance camera (step 306). That is, the camera control unit 280 controls the selected performance camera, for example, 098108211 22, for example, to start zooming in, etc. *9Rn, the shooting operation In addition, when the camera list 260 is not registered with the performance of the photo-expanding muddy earth, the distance between the main character and the obstacle is selected as the pick-up performance, and the case is 'camera control unit 280'. After the =: show camera is moved to the main character side of the obstacle, the shooting operation for the performance is started. For example, as shown in Fig. 7 of the ϋΓ0, the position of the show camera EC3 is moved to the real SB3. The photographic movement <the point of view (the lens part in the figure) highlights the obstacle and can be on the main character SC: after the position of the photography, the 〜~像也纷部290# The game image of the viewpoint is controlled by the controlled performance camera. The money is used to determine whether there is a shadow of the selected camera (the camera that moves out of the camera) and the obstacle between the main characters (step S307). In the performance operation of the performance camera, it is determined whether there is a new obstacle between the performance machine and the main character. " The image generation device 2GG determines that there is no obstacle (step s 3〇7; ) The process proceeds to step S310, which will be described later. In addition, when it is determined that there is an obstacle (step s 307; the imaging device 200 determines whether the distance between the main character and the obstacle is equal to or less than the reference value (step S308). ). 5米以下。 The distance between the main angle and the obstacle is determined to be 1. 5m or less. Further, the reference distance can be appropriately changed in accordance with the situation in the game or the like. 098108211 23 1379699 The image generating device 200 determines that the distance between the main angle and the obstacle is not equal to or less than the reference value, that is, when the distance is larger (far) than the reference value (step s 3 〇 8 ; n 〇), the processing is advanced to the back. The step S31() e, that is, controlling the performance camera, and maintaining the shooting operation for the performance. At this time, the camera control unit 280 continues the performance operation after moving the position of the show camera to the front of the obstacle (the point where the obstacle is highlighted and the main character can be photographed). In addition, due to the movement of obstacles, etc.

When the situation is blocked, the position of the show camera can be changed and the action is continued. In other words, the reference object position management unit 23 〇 makes the obstacle (color piece) a moving object and moves at a predetermined speed (movement amount) (7) = the moving direction of the object is different from the line of sight direction of the performance camera. When the situation is over, the camera control unit 28 does not change the position of the show camera, and performs the action. ' The aspect of the disc is that the distance between the main angle and its obstacle is the reference value.

From the player from the three directions, a camera that can be photographed by the main character without being obstructed by the obstacle is appropriately selected and photographed. In addition, for example, when all the performance cameras are obscured by obstacles, the obstacle camera is also selected to leave the farthest performance camera of the main character, and the performance camera is moved to the front of the obstacle (the obstacle is highlighted by the viewpoint and the main character can be taken care of) Position) and photograph the protagonist. Therefore, the performance camera will not be too close to the protagonist, but can produce an image of the #.

As a result, even in the presence of an obstacle, an image that is appropriately photographed for the main character to be noticed can be generated. (Other Embodiments) In the above-described embodiment, the case where the performance of the show camera is zoomed or the like is performed normally (in the same manner as in the prior art), but when the amount of movement of the show camera is larger than a predetermined value, It is also possible to perform a gradual movement using position interpolation or the like, but to move instantaneously. For example, when the movement amount of the camera is released for a certain period of time (for example, when j/ is D movement & distance, the performance camera does not move by interpolation 098108211 25 1379699, but moves instantaneously. In this way, via In the above-described embodiment, the case where the main character is used as an example of an eye-catching character and the main character is photographed by the performance camera may be described. However, the main character may be photographed. The character (which can also be an NPC or the like, or other moving object, etc.) is used as an eye-catching character, and the character is photographed by the performance camera. For example, when an event of the character X becoming the protagonist is played, the character X is played. In this case, in the same manner as described above, the show camera is placed so as to face the character X from the three directions. Then, any show camera that can be photographed without being obstructed by the obstacle is selected, and the like. The performance camera is generated from the image of the character X of the shooting while performing the action. In the case where there is an obstacle, it is possible to generate an image of an appropriate photograph for the character who is noticed. In the above-described embodiment, three cases are arranged so that photographing can be performed from any of the three directions. In the case of a camera, the number of the show cameras is not limited to three, and may be used as long as it is two or more. As described above, according to the present invention, even in the presence of an obstacle In addition, the case is based on the Japanese patent case No. 2008-065473, and the contents of the basic case are all added to the case. 098108211 26 137.9699 Λ (Industrial UTILITY) As described above, it is possible to provide an image generating device, an image generating method, an information recording medium, and a program that can generate an image that is appropriately photographed by an eye-catching character even in the presence of an obstacle.
