<p>Disclosed herein is an image processing apparatus for determining the rate of UCR (under color removal) for each color by a function of each of color signals. The image processing apparatus basically comprises a device for determining the maximum value Max and the minimum value Min of each of input signals Yi, Mi and Ci, and a device for determining the rates of UCR indicative of YU, MU and CU from the input signals Yi, Mi, Ci and the maximum value Max and the minimum value Min, using respective functions FY, FM and FC. The above-described YU, MU and CU can be determined in accordance with the following equations: YU = FY (Max, Min, Yi> MU = FM (Max, Min, Mi> CU = FC (Max, Min, Ci) <IMAGE></p> |
