ABSTRACT:
An image processing system which processes an input image such as a halftone image or an image having a high periodicity into a two-level image by use of dither matrixes. Peaks of an auto-correlation of the image are calculated and, then, a mean period of the calculated peaks. An adequate dither matrix is selected in response to the calculated mean period.
