Abstract
A system for reading an image formed on a silver-salt film, comprising: (a) a magnetic information reading unit for reading magnetic information recorded on a magnetic recording medium on the film; (b) a feeding unit for feeding the film; (c) an illuminating unit for irradiating light to the image formed on the film; (d) a filter unit arranged between the illuminating unit and the film; (e) a photoelectric conversion unit for receiving the light from the illuminating unit, which is passed through the film, to convert the image formed on the silver-salt film to an electric signal; (f) a memory unit for storing an image signal from the photoelectric conversion unit; and (g) a control unit for controlling at least one of the feeding unit, the illuminating unit and the photoelectric conversion unit, on the basis of information of the information reading unit.
