ABSTRACT:
A film scanner is capable of reading an image formed on a film in accordance with a photographing mode recorded in each frame of the film. In this film scanner, an image formed in each frame of a film held by a film holder is projected onto a linear image sensor by a focusing optical system to read the image with the linear image sensor. A magnetic information detection unit detects magnetic information recorded in each frame of the film, and a system controller identifies a photographing mode of each frame of the film. In accordance with the identified photographing mode, an image read area of each frame is set and a subscanning motor is driven in accordance with this image read area. The subscanning motor is driven in the area outside of the image read area at a faster speed than in the image read area. Therefore, a read time can be shortened as compared to the case wherein all frames are read in the broadest image read area. Trimming works can be omitted.
