Claim:
1. An image color enhancement method for a display, comprising 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 by a data acquisition module; obtaining a RGB triangle of color gamut of the display according to the chrominance value by the data acquisition module; for a chromaticity point D by an initial saturation calculation module, wherein O is a relative chrominance point when RGB=(255,255,255), D is an interaction point of line OD 1 and the RGB triangle, OD 1 is distance between the relative chrominance points O and D 1 , line OD 1 is a straight line connecting the relative chrominance point O and the chromaticity point D 1 , OD is distance between the relative chrominance point O and the interaction point D, and line OD is a straight line connecting the relative chrominance point O and the interaction point D; adopting a gain function to conduct gain computing for the relative saturation S acquiring the relative saturation S according to a formula OD computing the RGB data corresponding to the chrominance point D displaying the image on the display according to the RGB data after saturation enhancement.
