Abstract
An intelligent method and system for expanding and enhancing the color content of video or image to a wider color gamut to make the displayed video or image more pleasing while certain important and sensitive colors such as skin colors are preserved to avoid the perception of visually unnatural image or video artifacts. With the implementation of such method and system, the merits of the wide color gamut display can be fully utilized to provide videos and images of high visual quality.
