Abstract
A method of performing gamut mapping on an input image for an image output device includes receiving the input image to analyze a color distribution of the input image; determining a protect range corresponding to a first percentage of color codes of the input image and a compression range corresponding to a second percentage of the color codes of the input image based on the color distribution of the input image; and moving at least one of the color codes of the input image outside the protect range of the color codes to the compression range by a compression algorithm to perform gamut mapping on the input image.
