ABSTRACT:
An image processing apparatus includes a scanner for inputting image data indicative of an image with a multilevel tone, a multilevel data part for generating multilevel tone data from the input image data through a prescribed error diffusion process, the multilevel data part outputting image data having pixels to which the multilevel tone data is assigned, a storage part for temporarily storing a value of one of two successive pixels included in the image data, and a two-pixel processing part for converting the value of the one pixel stored in the storage part into a first value, and for generating second values of the two successive pixels using the first value of the one pixel, so that output image data is output to a printer, each pixel of the output image data being described by the second values of the two successive pixels.
