LOOKUP TABLE GENERATION METHOD, LOOKUP TABLE GENERATION DEVICE, AND COLOR CONVERSION DEVICE

摘要

PROBLEM TO BE SOLVED: To realize precision color representation for the color of a specific image, by a single lookup table regulating a correspondence relation between a color material use amount according to color material of a printer and a color material use amount according to a color material of an image formation device. ! SOLUTION: An lookup table 200 is generated by regulating a correspondence relation so as to indicate a first output characteristic about a first region R1 containing a color UCi that is contained in a specific image 400 in an input color space represented with the color of first color materials CL1 and regulating a correspondence relation so that a second output characteristic that is different from the first output characteristic is indicated for a second region R2 that is different from the first region R1 in the input color space when the lookup table 200 is generated, regulating a correspondence relation between the use amount of the first color material CL1 that is used for f
