ABSTRACT:
A gamut mapping apparatus includes a parameter calculating unit calculating parameters for segmenting a gamut of an output device using gamut information about first and second input color spaces; a gamut segmenting unit segmenting the gamut of the output device into a core gamut and a surround gamut using the parameters; and a gamut mapping unit performing gamut mapping on image data present into the first and second input color spaces to the core gamut and the surround gamut according to a predetermined mapping method. The gamut mapping apparatus and method enable accurate reproduction of image data having components having undergone total internal reflection falling outside the scRGB color space or high chroma components in the scRGB color space.
