Abstract: A high saturation algorithm for gamut mapping with a minimized color difference is presented. The color space is partitioned into 5 subareas by studying the relationship between saturation of mapping and geometric characteristics of the destination gamut. In each subarea, a different mapping strategy is selected to improve the saturation and precision of colors after mapping. Particularly, a method of variant anchor is used in the subarea which contains the maximum chroma point to ensure the color continuity of the mapping result. Experimental results show that the algorithm greatly enhances the saturation and precision of color reproduction, and significantly improves the quality of the color image output.
