Patent ID: 7583846

Claim:
A texture image compressing system, comprising: a data processing unit; a memory unit; and a texture image compressing module which is stored in the memory unit, and which is processed by the data processing unit; wherein the texture image compressing module includes: a separating unit configured to rearrange a plurality of texture images corresponding to a plurality of different light source directions and a plurality of different viewpoint directions into a plurality of rearranged texture images by grouping pixels included in the plurality of texture images per viewpoint direction and coordinate on each of the texture images, and separate intensity maps including intensity values and light source-independent texture images including color components from the plurality of rearranged texture images; an intensity map compressing unit configured to compress the intensity maps to generate compressed intensity maps and representative intensity maps that are codebooks of the compressed intensity maps; a light source-independent texture image compressing unit configured to compress the light source-independent texture images to generate light source-independent texture compressed images and color component conversion tables that are codebooks of the light source-independent texture compressed images; and a compressed texture generating unit configured to generate compressed textures by combining the compressed intensity maps, the representative intensity maps, the light source-independent texture compressed images and the color component conversion tables.
