  • Color transform method for preferential gamut mapping of colors in images
    Patent number: 6850342
    Abstract: A method for generating a transform for converting a digital color image signal expressed as color values in a first color space having a first color gamut to code values for driving an output device having a second color gamut different from the first color gamut includes the steps of: transforming the color values of the first color space to color values in an intermediate color space; specifying one or more predefined color regions in an intermediate color space; preferentially mapping the color values in the intermediate color space into the second color gamut by smoothly translating the color values to fit the second color gamut while restricting the mapping to regions outside of the predefined color regions to produce enhanced modified color values in the intermediate color space; and transforming the modified color values to code values for driving the output device.
