Abstract
An image synthesizing system is provided which can increase the speed of its hardware and reduce the scale of the same by using the subsampling/interpolation. A processor unit (80) determines coordinates of each dot and associated texture coordinates in polygons based on image data of vertices. A field buffer unit (40) stores the texture coordinates at its address specified by the coordinates of each dot. The texture coordinates are read out from the field buffer unit (40) and then used to read out rendering data from a texture data storage unit (42) to synthesize and output a pseudo 3-D image. In this case, the processor unit (30) includes a subsampling unit. Texture coordinates of the dots ignored by the subsampling unit are determined on the texture coordinates of dots adjacent to the ignored dots through interpolation circuits (180)-(186).
