Abstract
An image synthesizing system is provided which can output a high-quality image in real time through the texture mapping without preventing the hardware from being increased in speed and reduced in scale. A 3-D image is formed by a game space processing unit (13) and image supply unit (10) to perform a 3-D computation. At a processor unit (30), coordinates for each dot in a polygon and the corresponding texture coordinates are determined. A field buffer unit (40) stores the texture coordinates at an address specified by the coordinates for each dot. A texture data storage unit (42) has stored a rendering data. The texture coordinates are read out from the field buffer unit (40) and then used to read out the rendering data from the texture coordinate storage unit (42) to synthesize and output a pseudo 3-D image. By thus storing the texture coordinates in the field buffer unit (40), the subsampling/interpolation and the like may be carried out.
