Abstract
Abstract There are provided a geometry transfer engine (GTE) 61 and a graphic processing unit (GPU 62) which act in combination as a transforming means for converting three-dimensional image data retrieved from a CD-ROM disk into two-dimensional image data for drawing an image on a two-dimensional display screen, and a frame buffer 63 which serves as a memory having an image data storage area (picture data area) for storage of the image data and at least a color data tables storage area (CLUT area) for storage of multiple color lookup data tables in a two-dimensional arrangement, each color data table including a color data wherein the structure is arranged substantially identical to that of each pixel of data in the image. A greater number of colors are thus facilitated and the data processing is simplified.
