Because the accuracy of gamut boundary description is significant for gamut mapping process, a gamut boundary calculating method forLCDmonitors is proposed in this paper. Within most of the previous gamut boundary calculation algorithms, the gamut boundary is calculated inCIELABspace directly, and part of inside-gamut points are mistaken for the boundary points. While, in the new proposed algorithm, the points on the surface ofRGBcube are selected as the boundary points, and then converted and described inCIELABcolor space. Thus, in our algorithm, the true gamut boundary points are found and a more accurate gamut boundary is described. In experiment, a ToshibaLCDmonitor’s 3DCIELABgamut for evaluation is firstly described which has regular-shaped outer surface, and then two 2D gamut boundaries (CIE-a*b*boundary andCIE-C*L*boundary) are calculated which are often used in gamut mapping process. When our algorithm is compared with several famous gamut calculating algorithms, the gamut volumes are very close, which indicates that our algorithm’s accuracy is precise and acceptable.
