Abstract
An image processing system processes an input image data related to a dot image which is obtained by scanning a document in a scanning direction. The image processing system smoothens a density of a dot image based on a predetermined smoothing matrix and successively outputs smoothened picture element data which constitute an image data, delays the smoothened picture element data by a predetermined time in the scanning direction, successively averages two picture element data having a mutual time difference equal to the predetermined time and outputs average values, and subjects the average values to a pseudo halftone process.
