Abstract
A method for processing a digital gray value image includes the steps of: generating a binary edge image from the gray value image so that edges present in the gray value image are determined as line areas around the edges; applying a sharpness algorithm in the gray value image within regions which correspond to the line areas; and, carrying out a smoothing process in the gray value image within regions which lie outside of the line areas so that an additional smoothed, sharpened gray value image is generated.
