    摘要: Optimized color codecs and methods of compressing and decompressing color images using programmable color space parameters are provided. In accordance with one method of encoding a color image, input data comprising input image pixel data and color space parameters is provided. The input image pixel data is compressed based on the color space parameter data. The color space parameter data is then appended to the compressed image pixel data. In accordance with one method of decoding a compressed color image, compressed data is provided that comprises compressed image pixel data and color space parameters. The color space parameters are separated from the compressed image pixel data. The compressed image pixel data is then decompressed based on the color space parameters.

    摘要: A color management system is described herein. Various embodiments of a method described herein can include receiving source color content that is associated with a source device, and transforming the source color content into destination color content for rendering on one or more destination devices. Various embodiments of an apparatus described herein can include a color infrastructure transformation engine that further includes a sequential transform component, which is adapted to receive source color content and to create a transform to facilitate mapping the source color content to destination color content. The color infrastructure transformation engine can also include a transform optimization component that is adapted to receive the transform and to create an optimized transform table based on the transform, and a transform execution component that is adapted to receive the optimized transform table and to generate the destination color content based thereon.
