ABSTRACT:
A color value operation unit generates the sum of C, M, Y and K signal levels inputted from an external device by pixel. A control value operation unit compares the total Color.sub.-- In of the levels of each of the color components generated by the color value operation unit and the maximum input level Color.sub.-- Lim indicating the capability of a printer, then generates a limitation value Lim which is used for converting the input image signal levels to levels within the capability of the printer. A control processing unit reduces the input signal levels by using the limitation value Lim output from the control value operation unit, then outputs the image signals whose levels are reduced to the printer. Therefore, even in a case where C, M, Y and K image signals generated in an external device are input to a printer of a color copying machine, the levels of the input image signals are controlled in accordance with the capability of the printer, thus it is possible to output an image of high quality.
