ABSTRACT:
In a image processing system for an electrophotographic printer, a density selective circuit selects density data of a pixel to be corrected in response to the black-and-white patterns of surrounding pixels in a line matrix, and a density correction operation circuit outputs a picture signal with corrected density data corrected by the selected density and other density correction coefficients, thereby the toner adhesion amount, i.e., the printing density is made uniform and a clear printed picture without density unevenness can be obtained irrespective of the content of the picture signal.
