Abstract
A method is disclosed of operating on a stored digital image produced by scanning the photographic element to smooth film-grain noise. The method includes extracting and storing a set of statistics of the grain pattern of the film type carrying the image, such statistics being representative of local, spatial, and spectral properties of a photographic grain pattern of that type of film; and using the stored set of statistics to operate upon the stored digital image to change such stored digital image so as to smooth film-grain noise when an image is produced.
