System and method for sculpted gamut color conversion
Abstract:
The subject application is directed to a system and method for sculpted gamut color conversion. First gamut data is received related to a first color gamut defined by a primary color space having no black component. Second gamut data is then received related to a second color gamut defined by a primary color space inclusive of a black component. At least one first color value of the first color gamut is then mapped to a second color value of a portion of the second color gamut disposed outside of the first gamut. At least one fractional black component value is then selected for each mapped color value. Non-black color data associated with each selected fractional black component is then identified. A sculpted gamut is then generated in accordance with each selected fractional black component and associated non-black color data. A color image is thereafter generated corresponding to received image data in accordance with the generated sculpted gamut.
