Abstract:
A proposition is to perform a high accurate chromatic coordinate conversion of a chromaticity value generated by a color sensor into a chromaticity value of a predetermined chromaticity coordinate system, and to perform an accurate color-reproduction. A chromatic coordinate converting apparatus includes a recording unit recording information representing a chromaticity coordinate system unique to the color sensor in advance, and a converting unit performing a chromatic coordinate conversion of a first chromaticity value being a chromaticity value generated by the color sensor into a second chromaticity value of the predetermined chromatic coordinate system based on the information recorded by the recording unit.
