Patent ID: 8666163

Claim:
An apparatus for matching colors between various image devices, comprising: a characterization model generation unit configured to generate characterization models for color conversion of an image shooting device and an output imaging device using gamut information on the image shooting device and the output imaging device; a color conversion unit configured to convert all colors corresponding to a gamut of the image shooting device into colors corresponding to a gamut of the output imaging device using the characterization models; a lookup table generation unit configured to generate a lookup table between the image shooting device and the output imaging device based on color conversion information of the colors corresponding to the gamut of the image shooting device; and an image conversion unit configured to generate an output image of the output imaging device, of which the colors are matched with those of the image inputted from the image shooting device, using the lookup table; and a gamut extraction unit configured to extract gamut information on the image shooting device from an image in which a color patch is shot by the image shooting device, the color patch serving as a reference of gamut information extraction, and extract gamut information on the output imaging device based on color measurement information of the color patch image outputted on a screen of the output imaging device.
