200950856 VI. Description of the Invention: [Technical Field] The present invention relates to an image generating apparatus, a method, a program, and a program for generating an image suitable for photography of a foreign character even in the presence of an obstacle. . [Prior Art] = Developed as a game device for home use or business (I would like to use the tnr music 3D display action game or role-play game game. In such a 3D display action game, etc. Twins:: Use:: See the virtual camera to view the image, and display it. In addition to the protagonist in the virtual space, the muscle is also equipped with =, and his object is located between the protagonist and the camera. When the tree object is located between the main character and the camera, the obstacle of the camera's line of sight. The π piece becomes in this state, when directly generated from the photographic protagonist is hidden by the obstacle (all or: f> like] 'Illegal operation of the player. L can't see the image of the image, but the obstacles revealed by this kind of bad countermeasures', the surface of the New Moon's curved obstacles (for example, Japanese Patent Special Open U, 42=f' is easier to see [content of the invention] No. 098108211 200950856 (Problem to be solved by the invention) In the above-mentioned mode of the third dimension _- when there is any event, an action game or the like, for example, When the camera is turned into a point of view (10) ^ when the angle is noticed, 'from the time 戍 ^ ^ r ^ ', for the positioning of the shooting at the predetermined shooting position, the photography is used to capture the photo-evolution--the evolution of the shirt, And this kind of performance image is displayed. (φ (the machine in the machine 'shows the bow to pick up the player's attention to the performance image than what is the money for the actor's main character Na obscured. In the prior art limited to the protagonist There must be no obstacles around it = the condition in which the object exists (for example, a wide-angle apartment without buildings or trees generally uses such a performance camera. 5 The requirement for the proximity is based on the player's method of adding the game. In the game where the inner valley (scene or situation, etc.) covers multiple disparities, the display of the obstacles is also performed in the presence of such obstacles. To meet such requirements, for example, 'considering the use of the performance camera for photography, Check if there is an obstacle, and when there is an obstacle, make the show camera closer to (moving to) the main character side than the obstacle, and enter it without being obstructed by the obstacle. Photography. 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. Big), can not fully achieve the task of performing a camera. 098108211 5 200950856 (Therefore, it is required to consider obstacles, and to take advantage of the technology of photography. ^ Photo 4 can be appropriately used to solve this problem, the purpose is to mention In the case of the situation, it is possible to produce an image of the obstacle-producing device, the image-generating method, the information recording method, and the image of the process image (the means for solving the problem): the image-generating device of the first aspect of the invention is used as the viewpoint.

Evaluation of the camera control unit First, the position of the object position memory (4) in the virtual space. In addition, the object of the fourth day is stored in the position memory of the camera for the purpose of photographing the eye in the same direction. The obstacle determination unit sets each according to the memory: Each camera and note:: = one:::: The part is judged to have no obstacles, for example, the zoom-in 2 camera control is used to control the selected photographic image generating unit to produce a shooting operation. Then, that is, make Chen different party = 鸠 __ image. The camera that is not obscured by obstacles can be selected from the camera of the character camera and photographed 098108211 200950856. Therefore, even if there is an obstacle, the character can be photographed. As a result, even in the presence of an obstacle, it is possible to produce an image in which the character is properly photographed. * When the obstacle selection unit determines that there is an obstacle to all the cameras, the camera selection unit selects the camera whose distance between the target character and the obstacle is the farthest; and (0, the camera (4) In the case of moving the selected character to the attention character side of the obstacle, for example, the shooting operation for the performance is performed. In this case, even if all the cameras are covered by the obstacle, the selection is pure. The farthest camera that moves the camera to the front of the obstacle (the position where the eye can be photographed by highlighting the obstacle) and photographing. Therefore, the camera is not too close to the target character' The appropriate image may be generated. The camera control unit may 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 photography after the shooting operation for starting the performance; and _ When it is determined that there is an obstacle, and the distance between the target character and the obstacle is equal to or greater than the reference value, the camera control unit is After the camera moves to the attention character side of the obstacle, for example, the shooting operation for the performance is continued. In this case, even after the selected camera starts the shooting operation, even if a new obstacle is blocked, the camera can be made The camera moves to the barrier 098108211 7 200950856 (The camera continues to produce the correct obstacle in front of it (the position of the viewpoint can be highlighted by the viewpoint), and the shooting operation can continue. Therefore, the image can be used. After the camera control (4) starts the performance photography operation, the obstacle object portion is successively determined whether or not the obstacle between the respective camera = the character is masked; and '

When it is determined that there is an obstacle between the camera and the eye-catching character in the photographic process, and the distance between the eye-catching character and the obstacle is shorter than the reference value, the camera selecting unit selects any camera that is determined to have no obstacle. One of the cameras selects any one of the other cameras that are determined to have no obstacles; 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 obstacle (a obstacle close to the attention character) is blocked, the camera can be reselected 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 directed to an image generating device having a memory unit, an arithmetic unit, and a drawing unit, and generates an image for photographing a character placed in a virtual space by using a virtual camera that is a viewpoint.

In the case of the cymbal type, it is possible to have a function as an image generating device. (Summary structure of the image generating device) Fig. 2 is a schematic view showing a schematic structure of the image generating device of the embodiment. An example of the image generating device is In the case of a three-dimensional display action game or a role-playing game, etc., when a promising event occurs, and the protagonist receives attention, the virtual camera that becomes the viewpoint at the time is switched to the performance camera (the virtual camera for the performance). The character (the subject that will be noticed) is used for zooming or panning, etc. As shown in the figure, the image generating device i 200 includes an object information storage unit 210, an operation accepting unit 22G, an object position managing unit 230, a camera setting management unit 240, and an obstacle determining unit 25, The camera list 26A, the camera selection unit 270, the camera control unit 280, and the image typography unit 290. The first object first reads the main character (兀豕 character) in the virtual space, the enemy character, the tree, Various objects such as rocks and buildings 098108211 200950856 ( ( = = 贝讯. Specifically, for each object, the memory is called the information of the 3-dimensional model or texture. In addition, the RAM 103 # has a function as an information memory of such an object.彳 (4) New Zealand (10) accepts the player's operation of the operation of the county Xiao Xiaoxiang. For example, in the operation accepting unit 22, the player presses and moves in a predetermined direction, using a sword weapon (shooting, swinging a sword), picking up, squatting, squatting, etc.

The corresponding plurality of buttons (the instance is the direction key arranged in the controller 1〇5, the A button B button, the X button, the γ know, etc.) are used to accept the operation input to the main character. Further, the controller 105 has a function as such an operation accepting unit 22A. The object position management unit (10) is used to manage the position information (current position or direction, etc.) of the object that changes position in the virtual space of the main character or the enemy character. In the case of the object φ, the object position management unit 23Q manages the position information in accordance with the movement instruction received by the operation accepting unit 22G or the like, and changes the position or direction within the virtual space=. In addition, the enemy character moves in accordance with the established logic and changes the position in the virtual space. Therefore, the location information is managed in the same manner. Further, the object position management unit 23 also manages the positional information of the objects whose positions in the virtual space, such as buildings, trees, rocks, and the like are not changed. Further, the 103 and the CPU 101 have functions as such an object position management unit 230. The camera position management unit 24G memorizes a plurality of 098108211 15 200950856 facing the main characters from different directions ((the position of the performance camera. Specifically, the camera position management unit 240, as shown in FIG. 3, manages the three positions before the main character SC) The position information of the camera EC1 to the third is displayed. In addition, the direction (photographing direction) of each of the show cameras ECb EC3 is managed to face the main character Sc at the time of shooting. In addition, in Fig. 3, it can be easily explained that the table is from above. A plan view of the main character sc of the virtual space is seen in the following drawings. The following figures are also appropriately described in the above-mentioned plan view. The position information of the show cameras EC1 to EC3 may be an absolute position determined according to an event, or may be a protagonist according to an event. The position of % determines the relative position. = One instance is to pick up (get) a special weapon for the main character, and when it is a brother, decide to face the initial position of the weapon (position, etc.) 3 positions, etc. Packing 2: The case of one of the positions is an event that occurs after a predetermined period of time (for example, Anzhen exits the door: corner, explosion, etc.) In other cases, the position of the current position of the main character is separated by a predetermined distance, etc. In addition, the functions of the RAM 103 and the Cpn 1ni i are from the A lL _ _ 240. The CPU 1G1 has the position determination obstacle as the camera position management unit. (2) The object position management unit _ the position information of each object and the position information of the camera position management unit 24, respectively, determine whether or not the obstacle between the respective camera and the main character is blocked. 098108211 16 200950856 ( As shown in FIG. 4A, the obstacle discriminating unit 250 determines whether or not there is an object that becomes an obstacle on the line of sight VL from the show camera EC (EC1 to EC3) toward the main character SC. Further, the obstacle discriminating unit 250 As shown in Fig. 4B, it is possible to determine whether or not an object exists on each 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 as a base point. In Fig. 4β, in order to be easily explained, only the horizontal direction (the auxiliary line of sight HL is displayed in an enlarged manner, but the auxiliary line of sight HL is actually enlarged in the vertical direction as well. In this case, when the auxiliary line of sight HL is used, it is possible to determine whether or not one of the main characters is partially obscured by the obstacle. The CPU ιοί has a function as the obstacle determining unit 25〇. 2, the camera list 260 stores information of the show camera that is determined to be free of obstacles by the obstacle discriminating unit 25 (as shown in FIG. 5A) when there is an obstacle SB that obscures the line of sight VL2 of the show camera EC2 ( When the view, the line vu, and the VLS are not masked, the camera list 260' stores the information of the show cameras επ, (10) as shown in Fig. 5B. That is to say, in the 26G of the # machine county, the information of the camera that can be photographed by the protagonist without being obscured by the PI is blocked. Further, the 'RAM 103' has a function as such a camera list 26A. Referring back to FIG. 2, the camera selection unit 270 stores 098108211 17 200950856 stored in the camera list 260. (In the performance camera, for example, one camera is randomly selected. That is, one of the cameras determined to have no obstacles is selected. In addition, it is determined that there is an obstacle in all the cameras of the show, and the camera of the show camera is not stored in the camera list 260. In this case, the camera selecting unit 270 selects the distance from the main character and the obstacle. For example, as shown in FIG. 6A, the sight lines VL1 to VL3 of all the performance cameras EC1 to EC3 are blocked by the obstacles SB1 to SB3. In this case, the camera selection unit 270, As shown in Fig. 6B, 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 between the main character SC and the obstacle SB3 are respectively determined. Then, the distance is selected to become the maximum (distal) distance. The distance camera d3 corresponds to the performance camera EC3. In addition, there are also multiple obstacles on the line of sight of the performance camera.

In this case, the distance to the obstacle close to the main character is taken as the 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. The second t-camera control unit 280 performs an action of zooming, panning, shaking, etc., and photographs the image of the protagonist's action of the player's attention. Further, when it is determined that the obstacle camera selection unit 270 is present for all of the cameras, the distance between the selected main character and the obstacle is 098108211 200950856 (in the case of a video camera, the camera control unit 28{) is selected. After the performance camera moves to the main character side of the obstacle, the shooting operation for the performance is performed. For example, as shown in FIG. 7A, in the state where the performance camera ECb EC3 is obscured by the obstacles SB1 to SB3, the farthest performance is selected. In this case, as shown in FIG. 7B, the camera control unit 280 can move the position of the show camera (10) to the point of view (the lens portion in the figure) to highlight the obstacle SB3, and can photograph the main character sc. Then, the photographing operation for the performance is performed, that is, the obstacle camera SB3 is not moved, and the performance camera is moved to a photographable position as far as possible from the main character %. Then, the performance operation is started from the moving position. As a function of the camera control unit, the image drawing unit 29 refers to the information of the object stored in the object information storage unit (10). The information of the role managed by the location management department or the like, and the object in the virtual space (in the field of view) is viewed as a virtual video camera or a video camera controlled by the camera control unit 28 as a viewpoint game. Specifically, in the case of the event of the button, when the above-mentioned camera is selected, the image of the video is depicted by the camera department _ control _ _ _ _ _ _ _ _ _ _ _ _ _ In the magnification of the shooting operation for the performance controlled by the camera control unit 2δ〇, the viewpoint of the virtual EG is 098108211 19 200950856 moving from the position x to the position y. Therefore, the image drawing unit 29〇, as shown in the figure, will determine the game image captured by the camera EC at position X, and then expand the main character sc as the performance camera moves from position X to position γ. "As soon as, as shown in Fig. 8C, the game image captured by the show camera EC at the position γ is depicted. Further, when the show operation is panning or shaking, the image is drawn in the same manner as described above. 290 into drawing (position or visual line of sight green) images in accordance with the position and orientation of the camera performance.

Further, the 'image processing unit 1' 8 has a function 0 (operation of the image generating device) as such a video image capturing unit 29, which is a machine-specific image for indicating a real image in the image generating device 200 of the above configuration. Generate the process flow. The operation of the image generating device will be described below with reference to the figure. The image generating process is, for example, a tour!

When the predetermined event occurrence condition is satisfied, the camera list 260 is deleted (without any registration) at the beginning of the image generation process. Raw = 2, when the event occurrence condition is met, first, the video production, ° and then the position of the camera (step S301) 〇 = p in the landscape position management unit (10) set from * with the a direction facing = a show camera The location. That is, as shown in Fig. 3 described above, the position information of each of the show cameras ECb EC3 is set and managed by the camera 098108211 20 200950856 position management unit 240. In addition, the position of the performance cameras EC1 to EC3, such as the above, may be the absolute position determined by the event, or may be determined according to the position of the main character SC: the device is 2°°, whether there is a cover: : Obstacle between the machine and the protagonist' will have no performance list 260 of obstacles (step S302). In other words, the obstacle discriminating unit 250 separates the position information of each of the performance cameras based on the position information of each object and the camera position (4) of the object position management unit 23, and whether or not there is a masking orientation: An obstacle to the line of sight of each of the performance cameras. Then, the obstacle 250 is judged as the information of the show camera without the obstacle, and the list 260 is stored. That is, the camera list 260 stores information of a show camera that is not obscured by an obstacle and can be photographed to the main character. In addition, when it is judged that all the performances of the 10th camera are in a situation of obstacles, it becomes a list of the silk job (10) without any information of the performance camera. The image generation device 200 determines whether or not the information of the scene is recorded in the camera list 26 (step coffee 3). That is, whether or not there is one or more information on the camera list 26 that is not obscured by the obstacle and can be photographed by the protagonist. When the image generating device 2GG determines that the information of the show camera is registered in the camera list 260 (step S303; Yes), the process proceeds to the subsequent 098108211 21 200950856 (step S305 is described. The field is not registered for the camera. (Step S303; No), when the woman and the girl are in the case of the Becky, the shirt image generating device 200 obtains the distance between the main character and each obstacle (steps' obstacles). That is, since all the obstacles of the performance are obscured, the 赘 甚 ^ π ^ 摄 被 被 被 被 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 Di, the distance d of the main character % and the obstacle SB2, ?2, and the distance d3 between the main character SC and the obstacle SB3.

: Like production. The production device 2QQ selects one of the performance cameras (step S305). I first, s, when the camera list 26 is registered with the information of the show camera, the camera selection unit 27Q randomly selects one of the show cameras from the list, and the P is determined from the multi-camera that is determined to have no obstacles. Choose 1 cold shot n In addition, when in the photographic table? When one is registered, the movie camera is automatically selected.

Further, when the camera list 260 is not registered with the information of the information of the show camera, the camera selecting unit 27G selects the distance (the distance between the main obstacles and the obstacles) from the step s (the distance between the main obstacles and the obstacles). For example, in the case of the above-described figure, the performance camera EC3 that is shielded by the obstacle SB3 that is far away from the main character is selected. The image generating device 200 performs a shooting operation for the performance of the performance camera and generates a game image captured by the performance camera (step s 306). That is, the camera control unit 28 controls the selected performance camera, for example, 098108211 22 200950856 ( (for example, 'starting the shooting operation for the performance such as zooming in. Also, when the information of the show camera is not registered in the camera list 260, the selection is made. When the distance between the main character and the obstacle is the farthest to the camera of the show, the camera control unit 280 starts the performance of the camera shoulder after moving the selected camera to the main character side of the obstacle. For example, as shown in FIG. 7B above. As shown in the figure, the position of the show camera (4) is moved to the point of view (the lens portion in the figure) to highlight the obstacle 3, and the position of the main character % is photographed, and then the photographing motion for the performance is performed, and the image interpolating unit 290 depicts The video camera to be controlled is used as the game image of the point. The image capturing device 2 determines whether or not the selected camera (the camera that performs the shooting operation) and the obstacle between the main characters are blocked (step S3〇7). That is, in the performance action of the selected performance camera, it is discriminated whether there is a presence between the exit camera and the main character. New obstacles. The image generating device 2 determines that there is no obstacle (step s 3 .. No) 'Advances the processing to step S310 described later. On the other hand, it is judged that there is an obstacle. In the case (step s 3〇7).

Yes) The image generating device 200 determines whether or not the distance between the main character and the obstacle is equal to or lower than the reference value (step S308). For example, when the reference distance of the virtual space is set to 丨.5111, it is determined whether or not the distance between the main character and the obstacle is 1.5 m or less. In addition, the limit distance can be appropriately changed according to the situation in the game or the like. 098108211 23 200950856 (When the distance between the main angle of the image generating device and its obstacle is not below the reference value, that is, when it is larger than the reference value (far) ((4) s 3Q8; (4), the process proceeds to the steps described later. That is, the camera of the show is controlled and the shooting operation for the performance is maintained. At this time, the camera control unit 280 moves the position of the show camera to the front of the obstacle (the obstacle is highlighted by the viewpoint and the main character can be photographed) After the bit_set), the performance operation is continued. In addition, when the position of the camera is temporarily blocked due to the movement of the obstacle or the like, the position of the camera can be kept unchanged, and the operation can be continued. That is, the reference object position management unit 23G When the obstacle (object) is a moving object and is moved at a predetermined speed (movement amount) (when the moving direction of the obstacle is different from the direction of the line of sight of the show camera), the camera control unit 28G makes The position of the player is unchanged, and the performance continues. The other aspect is that the distance between the main character and the obstacle is below the reference value. In the case (step S308; Yes), the image generating apparatus _ re-enters the selection process of the performance camera (step § 309). That is, the shirt image generating apparatus 200 performs the same steps as the above-described steps S3〇2 to S3〇5. In the processing, the performance camera is again selected. The image capturing device 2GG performs the shooting operation (step S310). That is, it is determined whether or not the performance operation by the enlargement of the camera control unit 28 is completed. 098108211 24 200950856 ( Image generating device

Repeat step 310 above; Yes), image::: When the shooting operation is completed (Step S uses this image to generate the processing 2〇〇g to end the image generation processing. From the (4) from the 3 direction' In the presence of _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In the case of obscurity, the mobile camera 5 moves away from the protagonist's farthest performance camera, so that the performance camera moves to the front of the (four) object (the position of the main point can be photographed by highlighting the obstacle), and the main camera is taken. The _ machine will not be too close to the main character, but it will produce an image of 适. The result is that even in the presence of obstacles, it is possible to produce an image that is properly photographed for the main character to be noticed. (Other embodiments) In the above-described embodiment, the case where the zoom operation of the performance camera is performed normally (in the same manner as in the prior art) is performed. However, when the movement of the camera is larger than the predetermined value. It is also possible to move instantaneously without using gradual movement such as position interpolation. For example, when the movement amount of the performance camera moves a certain distance or more within a certain period of time (for example, 1 / 6 sec), the performance camera is not Interpolating 098108211 25 200950856 (moving, but moving instantaneously. In this way, by - to depict the image of the switched image. Delayed cutting switching can be described in the above embodiment, the case is a color ^ an example And use the performance camera to enter the corner of the main character, but it can also be used in addition to the protagonist, and the role (also can be NPc, etc.) as the attention or other moving color for photography. ❿ Using the performance camera, for example, when an event X is created as a protagonist's actor, and an event for each of the performances is generated, the sample is arranged in such a manner that it faces the character 3 from the three directions. You can choose to be photographed without being obscured by obstacles: you can set the camera twice. Then, the camera is produced in (4) Action (4) Photographing here In the case where there is an obstacle, the character can be appropriately imaged. In the above embodiment, the case is described in a manner that can be photographed from any of the three directions. In the case where three performance cameras are arranged, the number of performance cameras is not limited to three, and may be appropriately used as long as it is two or more. As described above, according to the present invention, even in the case of obstacles The condition of the existence of the object can also produce an image of proper photography of the target character. In addition, the case is based on the Japanese Patent Patent No. 2008-065473, and the contents of the basic case are all added to the case. 098108211 26 200950856 (Industrial Applicability) As described above, it is possible to provide an image generating apparatus, 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.
