Abstract

Camera motion, atmospheric turbulence, lens aberrations, image blurring, and diffraction limiting all degrade the quality of photographically recorded imagery. The photographic emulsion further distorts the image by introducing film-grain noise and attenuating high spatial frequencies. Although the objective or mathematical quality or the image becomes fixed on exposure, one can improve its subjective or visual quality by optical spatial filtering or electronic digital processing. As noted below, the success or failure of such techniques depends to a large degree on receiving sufficient exposure from the object scene.
