Abstract
A method and system enhances the color of an image by manipulating the chrominance and/or luminance signals of the image. Specifically, a color enhancement system sharpens color changes for better picture quality on digital display systems. In one embodiment of the present invention, color changes are detected by a color change detection unit. If the color changes are significant, a color change sharpening unit sharpens the color change to enhance the image.
