The colorimetric values of a plurality of reference color patches formed on a specific medium are measured at a plurality of temperatures, and a temperature characteristic LUT in a colorimetric value temperature correction unit is created based on the colorimetric values. Upon creating a calibration LUT, a patch based on arbitrary device values is formed on the medium, and a patch temperature and colorimetric values are acquired immediately after fixing of that patch. A correction target temperature as a temperature upon observation of the medium is, for example, fixed, the colorimetric values are corrected by interpolation processing based on the temperature characteristic LUT to obtain colorimetric values, and a calibration LUT is created based on the colorimetric values.
