METHOD FOR SHARPNESS ENHANCING AN IMAGE

A method for sharpness enhancing digital image data (ID), including: generating an intermediate processed image (IPI), in which uniform sections of the digital image data (ID) are cleaned from noise and in which at least one of a group consisting of contours, edges, wedges, structures and textures are detected, wherein the uniform section each fulfil a predefined uniformity criterion, which is descriptive for at least one of a group consisting of uniformity, flatness, structure, and noise content; deriving a blend value b for each pixel (Pbjkab) from the intermediate processed image (IPI) with b ranging between 0 corresponding to flatness and 1 corresponding to texture; two-dimensional sharpness enhancing the digital image data (ID) to generate processed digital image data (PID); and generating output data (outD) by pixelwise blending the digital image data with the processed digital image data.
