Abstract:
What is provided herein is a novel system and method which improves efficiency of a color management system performing a gamut mapping function. In one embodiment, a plurality of source colors are examined to determine whether any have changed. If not, then the source profile, the source device model, and the color appearance model have not changed. Next, the primary colors of the destination device are examined to determine whether any of these have changes. If these have not changed, then the destination device profile and the destination device model have not changed. When the source profile, device profile, color appearance model and the device models have not changed, gamut mapping does not have to be performed. The cached gamut mapping data are used instead. The gamut mapping data are used in subsequent mappings between these same two devices.
