摘要：
A system (600) for performing gamut compression or gamut extension by transforming an input color (608) of an input image defined within a first gamut (102) into a reproduction color (610) of an output image for rendering by a reproduction device capable of rendering colors within a second gamut (104) different from the first gamut. The input color has an input chromaticity (C1) and an input lightness (Z-*) together forming an input point (202) in a chromaticity-lightness plane. The reproduction color has a reproduction point (210) in the chromaticity-lightness plane, wherein an absolute difference between the input lightness and the output lightness is a decreasing function of at least the chromaticity. An absolute difference between the input chromaticity and the output chromaticity is an increasing function of at least the chromaticity.
