Patent ID: 8665290

Claim:
A color management method which converts a source-side color in a source device dependent color space into a counterpart destination-side color in a destination device dependent color space, said method comprising: obtaining a device independent source device gamut boundary for a source device and a device independent destination device gamut boundary for a destination device; obtaining a source color image in the source device dependent color space; transforming the source color image into a device independent image in a device independent color space; generating an image gamut boundary for the device independent image corresponding to the transformed source color image, based on the color content of the device independent image; modifying the source device gamut boundary by shrinking the source device gamut boundary in a hue symmetric manner, such that hues of colors do not change, until it touches the image gamut boundary; and mapping colors of the device independent image onto a gamut of the destination device by invoking a compression-type gamut mapping algorithm that uses the modified source device gamut boundary and the destination device gamut boundary to perform gamut mapping, wherein the gamut mapped colors are converted into destination-side colors in the destination device dependent color space.
