IMAGE PROCESSING APPARATUS AND METHOD, AND RECORDING MEDIUM

The present invention provides an image processing method for obtaining a conversion parameter to be used for a signal conversion process between body color image data and light source color image data, said method comprising the steps of calculating a conversion parameter to match color sight between a body color and a light source color with each other, for each of a plurality of representative colors and calculating the conversion parameter to be used for the signal conversion process, on the basis of the plurality of conversion parameters for each of the plurality of representative colors, whereby a conversion coefficient applicable to an entire image can be obtained, and the signal conversion process between the body color and the light source color can be performed well without being affected by any characteristic of device.
