Method and system for color image compression in conjunction with color transformation techniques

摘要

A method and system for compressing and color transforming image data are presented. Color transformation is a process whereby perceptional differences between the expressions of images in color devices are compensated. By transforming a compressed version of the image data, the amount of time in which it takes to perform color transformation can be reduced. Selection of compression techniques which maintain color characteristics of the image data in its compressed form permits the usage of color transformation techniques which already exist for the image data in its uncompressed form. The inventive techniques can be applied either prior to, or after, storage of the image data in an intermediate media or transmission from one device to another.
