This invention is a technique to presume colors of an image. A color extraction method according to this invention include a luminance calculation step of calculating a luminance in a color extraction region, which is included in an image and from which a color is to be extracted, and storing the calculated luminance into a storage device; a color name extraction of referring to a luminance database storing a color name and a luminance corresponding to the color name to extract a color name in the color extraction region by using, as a main judgment element, the luminance in the color extraction region, which is stored in the storage device. As a result, it is possible to presume a color even in a case of the monochromatic image or color image photographed in the night.
