Abstract:
The gamut of a printer has poor saturation reproducibility in a low-lightness region, often has a shape from which the gamut is cut away, and sometimes locally forms a part having extremely low color reproducibility. Hence, upon converting colors on a first gamut onto those on a second gamut, a third gamut is generated by transforming the second gamut for the purpose of the conversion, and the colors on the first gamut are mapped onto the third gamut. The colors on the first gamut are converted into those on the second gamut based on the mapping result.
