ABSTRACT:
A camera uses a film having a magnetic record member for each frame on film. When the film is loaded in the camera, the information recorded in the record member of each frame is detected. It is judged whether each frame is exposed or unexposed. Even if some frames on the leader side and on the trailer side of film were already exposed, the camera can perform accurate positioning of first unexposed frame and exposure on each unexposed frame.
