Abstract
Official abstract text for this publication.
The embodiments of the present invention reduce the compression time in order to achieve a faster texture compression. That is achieved by guessing, i.e. estimating the best table or tables (e.g. from tables 0 to 7) representing luminance information, and to only execute the compression for the table(s) estimated to provide the best luminance information.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method in a processor for texture compression, wherein a texture to be compressed is divided into blocks, each comprising a plurality of pixels, and each block is represented by a base color and luminance information for each pixel, and wherein, for a block to be compressed, the method comprises: mapping the base color to a coordinate system, where axes of the coordinate system are the R,G,B color components; for a plurality of pixels of the block,…
