Abstract
The invention introduces a method for compressing texture tiles, which contains at least the following steps: classifying each pixel of a texture tile into one of a plurality of groups and generating a bitmap of the texture tile, wherein the bitmap contains information indicating to which group each pixel of the texture tile belongs; reducing dependencies between pixels of each group; lossless-encoding each pixel of the texture tile to generate a first compression result; and outputting the first compression result and the bitmap.
