Abstract
Abstract A film image registration system includes a film reader for optically reading a front surface of a film set therein to obtain a film image. A film illumination device emits light to illuminate the film from a back surface of the film. The quantity of light emitted by the film illumination device is controlled according to a given command. The film image is received and formed into an image data file which is stored in a mass data storage.
