Method for selecting colours for a colour image.

摘要

A method for selecting a limited number of presentation colors from a larger palette for a selected image. A three-dimensional color histogram of said image is generated (50, 52) and a first color is selected (54) based upon the color occurring most frequently in the image. Subsequent presentation colors are selected (58) by choosing one at a time those colors having the highest weighted frequency of occurrence wherein the weighting is such that colors closest to the previously selected color are weighted very little, while colors furthest away from the previously selected color are weighted the most.
