ABSTRACT:
Methods and apparatuses for color correction that includes gamma correction. One embodiment of the present invention pre-processes the native device information of a color device (e.g., a color display device) to generate pseudo-native device information such that when a single, unique function is applied on the pseudo-native device information, a customized look up table for gamma correction in a video card is generated. The customized look up table is calibrated for the optimization of color rendering for skin tone in one region in a color space while maintaining the gray colors for the user interface elements in another region in the color space.
