Abstract
An image processing apparatus providing a halftoning process such as error diffusion prevents an image contour distortion, as follows: data in an image to be processed is used to partially extend the image to be processed. Then error diffusion or the like is employed to provide a halftoning process. The extension is removed to obtain image data. A dot generation delay can be prevented that would otherwise be introduced such as when an extension-free image is halftoned.
