ABSTRACT:
In order to implement color matching with higher precision, a device that handles object colors and a device that handles light-source colors must be separately processed. Hence, when the device type is a device that handles light-source colors, control is made so as not to perform processing (forward color appearance model conversion and inverse color appearance model conversion) for converting colorimetric conditions of a colorimetric value file into viewing conditions. When the device type is a device that handles object colors, the processing for converting the colorimetric conditions of the colorimetric value file into the viewing conditions is performed, and a profile is created from the colorimetric values.
