PURPOSE: To effectively make good use of the correction processing result of a color signal of a correcting device for a duplicated image by reflecting the error of a corrected color signal as to the range of a reproducible color signal on color signals of peripheral pixels. CONSTITUTION: This image processor is provided with an error addition part 31 which adds an accumulated error S to a corrected color signal Pxy, a difference calculation part 32 which calculates the error E between the corrected color signal (d) outputted from the error addition part 31 and the range of the reproducible color signal, an error storage part 34 which stores the error E calculated by the difference calculation part 32, pixel by pixel, and an error arithmetic part 33 which adds the errors of peripheral pixels stored in the error storage part 34 at a specific ratio to calculate the accumulated error S of the object pixel. The error E between the corrected color signal (d) and the range of the reproducible color signal is added to the color signals of the peripheral pixels at the specific ratio and the corrected color signal is effectively utilized. |
