Edges improving processor for adjustable grey level output changes image data at specific pixel locations to include grey level image data for reducing serrated edging in an image.

摘要

A printing/display device (400) has an image-processing system (10). A scanner (410) scans a document by using an 8-bit signal to relay the scanned thickness. Raw scanned image data passes through a gamma corrector (414). An adjustable threshold value device sets a binary pixel value for a current incoming grey level pixel by applying a threshold value criterion. Applying preset criteria forms adjacent pixels. A current pixel is adjusted at grey level value. An Independent claim is included for a method
