If only one camera is registered in the camera list 260, the effect camera is automatically selected. Further, when the information of the production camera is not registered in the camera list 260, the camera selection unit 270 is the largest (far) among the distances (distances between the main character and each obstacle) obtained in step S304. Select a production camera corresponding to the object. For example, in the case shown in FIG. 7A described above, the effect camera EC3 blocked by the obstacle SB3 farthest from the main character is selected.
  • the image generation apparatus 200 generates a game image shot from the effect camera while performing an effect shooting operation on the effect camera (step S306). That is, the camera control unit 280 controls the selected effect camera and starts an effect shooting operation such as zoom-up, for example.
  • the camera control unit 280 selects the selected production camera. After moving to the hero character side from the obstacle, a shooting operation for production is started. For example, as shown in FIG. 7B described above, after the position of the effect camera EC3 is moved to a position where the substantial viewpoint (the lens portion in the figure) can penetrate the obstacle SB3 and the main character SC can be photographed. Perform the shooting operation. Then, the image drawing unit 290 draws a game image with the controlled production camera as a viewpoint.
  • the image generating apparatus 200 determines whether or not there is an obstacle that blocks between the selected effect camera (the effect camera performing the shooting operation) and the main character (step S307). That is, it is determined whether or not a new obstacle exists between the effect camera and the main character while the selected effect camera is in the effect operation. If the image generating apparatus 200 determines that there is no obstacle (step S307; No), the process proceeds to step S310 described later.
  • the image generating apparatus 200 determines whether the distance between the main character and the obstacle is equal to or less than a reference value (step S308). For example, when the reference distance in the virtual space is set to 1.5 m, it is determined whether or not the distance between the main character and the obstacle is 1.5 m or less. The reference distance may be changed as appropriate according to the situation during the game.
  • step S308 determines that the distance between the main character and the obstacle is not less than the reference value, that is, greater than (or far from) the reference value (step S308; No)
  • the process proceeds to step S310 to be described later. That is, the effect camera is controlled to maintain the effect shooting operation.
  • the camera control unit 280 continues the effect operation after moving the position of the effect camera to the front of the obstacle (position where the viewpoint can penetrate the obstacle and photograph the main character). Note that, when the obstacle is temporarily moving due to movement or the like, the rendering operation may be continued without changing the position of the rendering camera.
  • the camera control unit 280 continues the effect operation without changing the position of the effect camera.
  • step S308 when it is determined that the distance between the main character and the obstacle is equal to or less than the reference value (step S308; Yes), the image generation apparatus 200 performs the effect camera selection process again (step S309). That is, the image generating apparatus 200 performs the same process as steps S302 to S305 described above, and reselects the effect camera.
  • the image generating apparatus 200 determines whether or not the shooting operation for production has ended (step S310). That is, it is determined whether or not an effect operation such as zooming up by the camera control unit 280 is completed.
  • step S310 determines that the shooting operation has not ended (step S310; No)
  • the process returns to step S306, and the above-described steps S306 to S310 are repeatedly executed.
  • step S310; Yes the image generation apparatus 200 ends the image generation process.
  • shooting is performed by appropriately selecting a stage camera capable of shooting the main character without being obstructed by the obstacle from three direction cameras. Can be made. Also, for example, even if all the production cameras are obstructed by obstacles, select the production camera of the obstacle farthest from the hero character, and the front of the obstacle (the hero character with the viewpoint penetrating the obstacle) The effect camera is moved to a position where the hero character can be photographed, and the main character is photographed. For this reason, it is possible for the production camera to generate an appropriate image without being too close to the main character. As a result, it is possible to generate an image that appropriately captures the main character to be noticed even in a situation where an obstacle may exist.

Abstract

Selon l'invention, une unité de gestion de position d'objet (230) stocke des informations de position concernant chacun des objets comprenant le caractère de tête. Une unité de gestion de position de caméra (240) stocke des informations de position concernant une pluralité de caméras de représentation dirigées vers le caractère de tête à partir de différentes directions. Une unité d'évaluation d'obstacle (250) évalue si un obstacle est présent entre chacune des caméras de représentation et le caractère de tête selon les informations de position stockées concernant les caméras de représentation respectives et les informations de position concernant les objets respectifs, de façon à stocker des informations concernant la caméra de représentation qui n'est pas perturbée par un obstacle. Une unité de sélection de caméra (270) sélectionne l'une des caméras de représentation stockées dans une liste de caméras. Une unité de commande de caméra (280) commande la caméra de représentation sélectionnée et amène la caméra de représentation à effectuer une opération d'imagerie pour représentation. Une unité de représentation graphique (290) génère une image capturée par la caméra de représentation commandée.
