  • Method and device of skin tone optimization in a color gamut mapping system
    Patent number: 9336571
    Abstract: In a method of skin tone optimization in a color gamut mapping system, an image signal is first transformed from a predetermined color domain to an HSV color domain for generating an HSV image signal. Next, a skin tone optimization is performed on the HSV image signal for generating an adjusted saturation gain. Then, a color enhancement is performed on the HSV image signal according to the adjusted saturation gain and a color shift signal so as to generate a color enhancement signal. Finally, the color enhancement signal is transformed from the HSV color domain to the predetermined color domain.
