Patent ID: 7483172

Claim:
An image processing apparatus comprising an arithmetic processing apparatus for calculating image signals for proof in order for proofing a reproduced color with a proof apparatus when an original color image outputted from a first output apparatus is reproduced by a second output apparatus, wherein the arithmetic processing apparatus is configured to: create a first color conversion profile for converting original image signals for the first output apparatus into image signals for reproduction with the second output apparatus, by calculating a device independent color by the use of color gamut mapping; calculate, in the process to create the first color conversion profile, correlation information between each signal value of a device dependent color of the first output apparatus and the device independent color which is determined by the color gamut mapping; create a second color conversion profile for converting the original image signals into signal values derived from calorimetric values for reproduction with the proof apparatus, based on the correlation information; and convert the original image signal into the image signal for proof, based on the second conversion profile.
