Abstract

In the process of gamut mapping from monitor display into printer hardcopy in CIE L*a*b* color space, blue is tend to map to purple. This paper presents a new approach to solve the perceived blue hue shift problem. By this approach, the entire color gamut is divided into four regions: a non-blue region, a blue-region, and two in-between regions. The segmentation of the four regions is based on the hue angle in CIE L*a*b* color space. Different color spaces are applied to different regions for gamut mapping. In the non- blue region, CIE L*a*b* color space is applied for gamut mapping. In the blue region, CIE L*u*v* color space is applied to eliminate the perceived blue shift. In the two in-between regions, both color spaces are used for gamut mapping, and a weighting function is applied for smooth transaction.
