摘要： A film image input system is disclosed which provides an increased degree of feedom of design thereof, can be reduce the size and costs thereof, and can execute a trimming operation with ease. The film image input system forms an image of a developed still photo film 134 on a light receiving surface of an image pickup element 140 through a zoomable taking lens 138 and outputs to a monitor TV an image signal photo-electrically converted by the image pickup element 140 to thereby reproduce the film image on the screen of the monitor TV. The film image input system comprises at least one mirror 137 interposed between the photo film 134 and taking lens 138 for bending the optical axis of the taking lens 138, a mirror drive mechanism 168 for inclining the mirror 137 in all directions, and an operation part 170 for driving the mirror drive mechanism 168 in order to execute a desired scanning. This allows the system to be made compact and increases the freedom of design of the system.
