Abstract
The present disclosure relates a method to improve overlay mapping of out-of-gamut. The method includes: step, converting a RGB digital value to a L*a*b* value of a Lab color space; step, determining a hue plane where the color point P located, and further determining values of a hue angle H, a color saturation C, and a brightness L; step, determining a reference color point Pby combing intersections color point Pand color point Pwith the color point Land a parameter α; step, determining whether the color point P inside or outside a line |LP|; and step, converting a L*a*b* value into a RGB value in the target gamut. The method to improve the overlay mapping of out-of-gamut according to the present disclosure causes multiple colors to no longer be mapped to the same color point.
