Abstract

PURPOSE:To enable display easy colorimetry by displaying evaluated colors by using a color television monitor. CONSTITUTION:According to color specification data and respective coordinates of a chromaticity curve of a chromaticity diagram read out from fixed information memory part 10a of main memory unit 10, information on three primary colors on three-primary-color information table 10T is read out and through CPU11, conversion coordinate information is stored as addresses in video RAM14R, 14G, 14B. By the three-primary-color information converted analogically through level converter circuits 15R, 15G, 15B, the chromaticity diagram corresponding to a hue and chroma saturation is displayed in color on color television monitor 12. On the other hand, access to table 10T is attained according to digital display data of the colorimetry of a sample by colorimeter 1, and similarly color display of chromaticity corresponding to the colorimetric hue and chroma saturation at fixed coordinate positions of monitor 12 is carried into effet to make a direct decision on the color, so that since the substitution, etc., by monochrome display is unneeded, display can be attained which provides easy and accurate colorimetry.
