A process for the image sharpening of a photographic image with a
multitude of image elements is disclosed, wherein a correction mask for
the change of the image sharpness is determined from the image data
representing the image to be corrected, whereby the elements of the
correction mask for the change of the image sharpness locally describe
the degree of contrast change to be carried out for the individual image
elements, and whereby additional information relating to the image is
used for the determination of the elements in addition to information on
the local contrast.
