Abstract
A color gamut mapping maps an input image signal which has input pixel colors defined by an input luminance and an input chromaticity into a mapped image signal which has corresponding mapped pixel colors defined by a mapped luminance and a mapped chromaticity for a display. The input pixel colors lie within the input color gamut different than the display color gamut. The desired mapped luminance may be retrieved by looking up stored desired luminance values in a look-up table at the mapped chromaticity, or by calculating a relative to white luminance, or a luminance decrease, etc.
