Abstract
In an image processing apparatus which performs pseudo-halftone processing of multivalue image data, the multivalue image data are subjected to partial removal processing in accordance with an assigned reduction ratio, and the resultant multivalue data are then subjected to binary-coding processing. In partial removal processing, data of a removed picture element are reflected upon data of adjacent picture elements. Binary-coding processing is performed by referring to binary data of a predetermined region subjected to binary-coding processing. It is thereby possible to obtain an image having excellent gradation and resolution in a short time with a simple configuration of hardware, and to obtain an image not having deterioration of picture quality even in image reduction.
