COLOR CONVERTING DEVICE, COLOR CONVERTING METHOD, COLOR CONVERSION PROGRAM AND TEST PATTERN

摘要

PROBLEM TO BE SOLVED: To perform color correction corresponding to observation environment by an easy and inexpensive method. SOLUTION: In a first conversion process, it is possible to estimate how the colors of an image displayed on a display 60 are perceived under the observation environment. In a second conversion process, it is possible to specify CMYK values at which colors that can be perceived similarly to the perceived colors estimated in the first conversion process in an observation environment of a printing result. When estimating how the colors are perceived under the observation environment, environment parameters LA, c, Nc, F are substituted for a conversion profile, and the environment parameter LA, c, Nc, F can be obtained from illumination I. Since the illumination I can be specified on the basis of a visual result of a test pattern, there is no need to prepare an illumination photometer. COPYRIGHT: (C)2007,JPO&INPIT
