US Patent 7573610 Intelligent color gamut management method

An intelligent color gamut management method. The intelligent color gamut management method performs a saturation mapping and a luminance mapping separately according to a characteristic of a target device, thereby enabling the target device to represent a natural color image. Accordingly, it is possible to reduce color reproduction distortion of an image between different color devices having different color gamuts and also reproduce a natural color image, and also, secondary CMY colors, which vary depending on a color temperature, can be adjusted to be more natural. Since the color gamut boundary can be easily obtained, a memory capacity can be saved a freedom of algorithm can be increased.
