ABSTRACT:
Various embodiments provide for gamut mapping spectral content. Source appearance content is created from source spectral data corresponding to a source color image. The source appearance content is mapped to an appearance delta using a gamut mapping algorithm. Destination spectral data is derived from the source spectral data and the appearance delta by way of a spectral mapping algorithm. The appearance delta corresponds to two potentially different gamuts or color spaces. Humanly perceptible differences in the color appearance of a destination image as compared the source image are reduced by the mapping techniques provided herein.
