Abstract
Method of processing photoelectrically scanned image information representing different gray values, before such information is converted, by half-tone processing, into image information representing no more than two gray values, such that the scanned information is distinguished into different categories of information, each category being subjected to a filtering operation determined by the category, the information thus filtered for each category being suitable for subjecting to one type of half-tone processing.
