A digital image processing method includes the steps of embedding a delta function in a digital image; subjecting the digital image to an intermediate processing step, the intermediate processing step having a modulation transfer function (MTF) that blurs the image; extracting the delta function from the processed digital image; and estimating the MTF from the recovered delta function. The blur is removed from the image by generating a sharpening filter that is substantially the inverse of the MTF and applying the sharpening filter to the blurred image to produce an improved image.

Storing sharpness data using embedded carriers

An imaging element is described which comprises a colorless coupler compound which contains an oxidizable lueco dye moiety and optionally a colorless dye image-forming coupler compound. Following color development a masking dye is obtained by oxidation of the leuco dye moiety in areas where no photographic development occurs.
