Patent ID: 8482799

Claim:
A color processing apparatus comprising: a memory which stores a measured data table; a measurement section which measures color values; a first obtaining section, configured to obtain a first color value of a printing medium under a first light source which emits first light including light in an ultraviolet region and at a first temperature from either the measured data table or the measurement section; a second obtaining section, configured to obtain a second color value of the printing medium under the first light source and at a second temperature different from the first temperature from either the measured data table or the measurement section; a first estimator, configured to estimate a color value of the printing medium at a viewing temperature, which is different from the first temperature and the second temperature, from the obtained first color value and the second color value; a third obtaining section, configured to obtain a third color value of the printing medium under a second light source which emits second light including light in the ultraviolet region weaker than the first light from either the measured data table or the measurement section; and a second estimator, configured to estimate a color value of the printing medium at the viewing temperature and under viewing light, based on the color value of the printing medium at the viewing temperature and the third color value of the printing medium under the second light source.
