Method and apparatus for color gamut mapping color gradient preservation

Abstract:

A method and apparatus for gamut mapping color gradient preservation is described. In one example, the method and apparatus obtains a source image having a plurality of source color gamut pixels in a source color gamut, wherein the plurality of source color gamut pixels include a same hue value and a same luminance value and define a color gradient, and converts the plurality of source color gamut pixels to a plurality of target color gamut pixels such that the color gradient of the plurality of source color gamut pixels is preserved by the plurality of target color gamut pixels in a target color gamut. The method and apparatus provides the plurality of target color gamut pixels for display on a target color gamut display.
