Abstract:
A film scanner comprising:a first light source, which projects light onto film recording an original image; scanning means, which register an image corresponding to the original image by scanning light transmitted through the film; and light compensating means, which compensate insufficient light quantity due to disturbance of a light path from said first light source to said scanning means by an irregularity in the surface of the film, which causes an image of the irregularity to be formed in said scanning means, using the disturbance of the light path caused by the irregularity, wherein: condensed light projected from said first light source does not reach said scanning means after being refracted by a scratch area of the film and reaches said scanning means after passing through some portion other than the scratch area of the film, and scattered light projected by said light compensating means reaches said scanning means after being refracted by the scratch area of the film and does not reach said scanning means after passing through some portion other than the scratch area of the film.
