Abstract
An image processing method and apparatus is provided that executes conversion processing of image data according to an error diffusion method. A unit processing for one pixel of the original image and another unit processing for an interpolate pixel that is inserted between lines of pixels of the original image are executed in the line direction. The processings for one line are sequentially repeated for each line of the original image. A calculating portion, for calculating an average error value which is an average of error values of a plurality of neighboring pixels, is utilized for converting a pixel value of a target pixel. A plurality of multiplying sections and addition memory sections are provided in correspondence with the alignment of a plurality of previous-line-neighboring pixels in a previous line located ahead of a pixel line in which the target pixel exists.
