Abstract

An image color enhancement method for a display comprises the steps of: gathering tristimulus values of CIE1931 color space in light of all RGB combination of an image shown on the display, and computing a relative chrominance value and a relative luminance value; obtaining a RGB triangle of color gamut of the display according to the chrominance value; for a chromaticity point Dwhich is relative to the RGB triangle of a RGB data, defining a relative saturation is adopting a gain function to conduct gain computing for the relative saturation Sand obtaining a gain saturation S; according to a formula OD=OD*S, obtaining the gain saturation Srelative to the chrominance point Din the RGB triangle and the chrominance point Dis located in the line OD; computing the RGB data corresponding to the chrominance point Dand obtaining the RGB data after saturation enhancement. An image color enhancement device is for executing the image color enhancement method.
