Abstract
A method of noise reduction processing for reducing noise generated when an image of a photographic film is converted to a digital image signal includes the steps of: measuring a large area transmission density of each of a plurality of image frames recorded on the photographic film; classifying measured values of the large area transmission density into a plurality of groups; reading the image signals of the same image frame by an amount corresponding to the number of inputs of the image signals of the same image frame set in advance for each of the classified groups; and subjecting the image signals of the same image frame which have been read to averaging processing.
