Abstract

The main goals of the color image enhancement are to sharp contrast the image while preserving the natural appearance of the image. Some works have been done to process color images in luminance, hue and saturation attributes. But there are some problems by using these methods. Other attributes of the image color will been varied if one of its attribute is changed. In this paper, we analysis the true color image processing method, presented that the luminance value of the image color should be adjusted to suitable range, then the saturation enhancement under the certain luminance can be performed in the RGB color space, L*u*v* color space and L*a*b* color space to get the best saturation effect. We calculated some typical color differences produced by the luminance adjustment method and the saturation enhancement method. Then we compared the color differences in these three color spaces. As a result, we concluded that the different method should be chosen according to the different color images. Some images were processed with these methods and the best visual effect were obtained.
