Abstract
In an image processor on multi-level image data, an edge direction of a target pixel is discriminated from differences in density level between the target pixel and adjacent pixels thereof. A pixel is divided into a plurality of sub-pixels, and the image is formed in the unit of sub-pixels. The density level is set for each of the sub-pixels in the target pixel in accordance with the discrimination on the edge direction of the target pixel so that the center of gravity in density is changed in the target level. Then a character edge portion is reproduced more smoothly.
