Abstract
An image processing apparatus having a processor for calculating an image signal for proofing a proof apparatus, when an original color image outputted from a first output apparatus is reproduced by a second output apparatus. The processor is configured to calculate correlation information between each signal value of device dependent color of the first output apparatus and a device independent color, in a process of creating, by color gamut mapping, a first color conversion profile for converting an original image signal for the first output apparatus into an image signal for reproduction for the second output apparatus; to create a second color conversion profile for converting the original image signal into a calorimetric value or a signal value derived from it, based on the correlation information; and to convert the original image signal into the image signal for proof, based on the second conversion profile.
