Abstract:
A color management method using an input device appearance transform and an output device appearance transform together with a customizable gamut mapping algorithm, said method comprising the steps of:obtaining the input device appearance transform and the output device appearance transform based on each of input device color profile and an output device color profile; customizing the gamut mapping algorithm based on information in regard to the gamut mapping; compositing the customized gamut mapping algorithm with either the input device appearance transform and a color appearance model transform or the output device appearance transform and an inverse color appearance model transform, or both; generating an appearance look-up table; and transforming image data from an input colorant space to an output colorant space using the composited transform, wherein said gamut mapping algorithm operates in a perceptual color space, said perceptual color space is obtained by using the color appearance model transform.
