Patent ID: 8576442

Claim:
A color conversion coefficient generating apparatus comprising: a first color reproduction characteristic obtaining unit that obtains a first color reproduction characteristic that is obtained by correcting a color reproduction characteristic of a first device in accordance with a color of a first medium used for printing in the first device; a second color reproduction characteristic obtaining unit that obtains a second color reproduction characteristic that is obtained by correcting a color reproduction characteristic of a second device in accordance with a color of a second medium used for printing in the second device; a modifying unit that modifies the first color reproduction characteristic obtained by the first color reproduction characteristic obtaining unit and that repeatedly modifies the modified first color reproduction characteristic; and a generating unit that generates a color conversion coefficient for performing, in the second device, simulated printing based on the color reproduction characteristic of the first device on the basis of the first color reproduction characteristic obtained by the first color reproduction characteristic obtaining unit and the second color reproduction characteristic obtained by the second color reproduction characteristic obtaining unit, and that regenerates the color conversion coefficient on the basis of the first color reproduction characteristic modified by the modifying unit and the second color reproduction characteristic obtained by the second color reproduction characteristic obtaining unit, wherein the modifying unit modifies the first color reproduction characteristic on which a preceding modification has been performed and which has not been corrected in accordance with the color of the first medium on the basis of a difference between the first color reproduction characteristic obtained by the first color reproduction characteristic obtaining unit and a color reproduction characteristic that is obtained by correcting, in accordance with the color of the second medium, a color reproduction characteristic in a result of the simulated printing using the color conversion coefficient that is regenerated on the basis of the first color reproduction characteristic on which the preceding modification has been performed.
