Abstract:
Disclosed embodiments relate to techniques for color gamut mapping when an input signal transmitting color visual images has a different color gamut than does the output display device. Polynomial rubber-sheet mapping may be used to translate the input color gamut to the output color gamut on a hue-by-hue basis within a three-dimensional perceptual color space. Also, a memory color look-up table may be used to preserve memory colors in the input gamut which are capable of reproduction within the output gamut. By using such techniques alone or in combination, it may be possible to more effectively map an input color gamut to a different output color gamut with improved calorimetric accuracy.
