A CCD scanner is provided with a halogen lamp for irradiating illumination light for reading a frame image on a photographic film, and a halogen lamp for irradiating infrared light via an infrared light filter for detecting scratches and the like on the film surface, and the optical axes of the respective light sources are coincided by a half mirror. A diffusion plate turret is also provided for selectively placing each of a plurality of diffusion plates for diffusing the illumination light near the photographic film. As a result, it is possible to perform both an image reading that doubles as an erasure of scratching on the film surface using visible light having different degrees of diffusion and a detection of scratches and the like using infrared light. |
