摘要： A CD-ROM which records a game program and movie data is used to display a movie on part of a face of a character appearing in a game. A predetermined face object is placed in a virtual three-dimensional space. A region of which expression should be changed within the face object is specified. An image data reading unit sequentially reads frame images of movie data representative of a change of expression of the region from the CD-ROM to an image data buffer unit. An image data transferring unit sequentially stores the frame images into a plurality of buffer areas included in a texture data buffer unit, while switching the buffer areas. A texture mapping unit sequentially maps the frame images sequentially stored in the buffer areas within the texture data buffer unit to the region as texture data, in parallel to the storing operation.
