PROBLEM TO BE SOLVED: To prevent linear unevenness from occurring on a image after reducing and to contract an image. SOLUTION: If the rate of reduction is n/m, P (s) is density data of each pixel of one pixel row of an original image, Q (t) is density data of each pixel in one pixel row after an image after reduction, s (t) is a reference pixel No. of a processing range in the original image in calculating the Q (t), s (1) is a leading pixel No. of the processing range in one pixel row of the original image, and that ah is load correction quantity of the P (s(1)), the image reduction of one pixel row of the original image is performed, based on n arithmetic operations, i.e., Q (t)=((n-a(t))/m)×P(s(t))+Σ((n/m)×P(i)) (i=s(t)+1-s(t+1)-1)+(a(t+1)/m)×P(s (t+1)), s(t)=s(1)+int((ah+(m×(t-1))/n), and a (t)=(ahH+(m×(t-1))) mod. |
