Title: Color gamut displaying method, an image processing method, and apparatus utilizing these methods

Abstract: The host computer 2 defines a color gamut as a solid of a three dimensional space to represent a color reproduction area of a color reproduction device, and instructs to display the color gamut in accordance with combinations of information on the color reproduction area on the basis of a second and a third axes extending to both the positive and negative directions in a plane perpendicular to a first axis of the defined three dimensional space and coordinates of the first axis. For example, the information on the color reproduction area in the plane perpendicular to the first axis can be represented by a two dimensional area, a two dimensional coordinate area, bit map data, or two dimensional vector data, thereby the color gamut for realizing a color gamut checking function is easily confirmed.
