Abstract
The present invention is to provide methods and apparatuses for creating color conversion definition to make the same output result appear without any uncomfortable feeling when a same output result is observed under different illumination lights. To achieve this, the method comprising the successive steps of: (a) assuming an observational environment under an illumination light in which a difference in color appearance of an output result of the image output device in a plurality of observational environments with different illumination lights to observe the output result is made less; (b) determining measured color values of a device color of the image output device in the observational environment under the illumination light in which a difference in each color appearance is made less; and (c) creating a color conversion definition on the basis of the measured color values of the device color of the image output device determined at step (b).
