摘要
A histogram generating section generates a histogram for each channel of a color space which shows colors of pixels constituting an image, in which tone levels of said channel are divided into plural intervals as classes, and frequency of appearance of tone levels of the pixels in each interval is shown as degree. An interval extraction section extracts the intervals in each of which the frequency of appearance becomes local maximal value. A score calculation section calculates scores of the extracted intervals. The score indicates visibility of color to human based on human color sense. An interval selection section selects one or more extracted interval to be representative color, based on the calculated scores. A representative color extraction section generates the representative colors based on tone levels of the selected intervals.
