PURPOSE:To remove generated shading by reducing the correction output data difference between division points which adjoin to each other vertically. CONSTITUTION:The difference X between corrected data at two division points P11 and P21 which adjoin to each other vertically is ¦fA-fB¦, where fA and fB are corrected data at the division points P11 and P21. The difference X is reduced to N/M. Further, ¦f'Af'B¦=N/MX¦A-fB¦, where f'A and f'B are corrected data at the points P11 and P21 after arithmetic operation. When the total of the corrected data is fixed, f'A and f'B are calculated through software from f'A+f'B=fA+fB and outputted to remove shading.
