Abstract
An image processing unit comprises an image scanning unit for scanning an original at a plurality of predetermined line densities, a smoothing unit for smoothing the intensity of each pixel, the intensity of each pixel being corrected to be the average intensity of a predetermined number of pixels surrounding each pixel in a predetermined pixel area, a binarizing unit for binarizing the corrected pixel by a half-tone processing, and a pixel area changing unit for changing the pixel area based on the line density employed by the image scanning unit. The intensity of each pixel may be corrected, by using pixels included in the predetermined pixel area, based on the existence of a pixel corresponding to a contour or a fine line in the original in the pixel area. A clear image of a mesh picture is obtained without generation of moire, blurring of contours, or breaking of fine lines.
