Abstract
A controller uses image processing to detect any abnormalities in the shape and distance of the perforations of a motion picture film by means of image data obtained upon imaging the perforations of the running motion picture film by a video camera in a sensor unit arranged in the film running path. If any abnormalities are detected in the perforations in the motion picture film running in the film running path, an error output specifying such abnormalities is fed to a system controller that operates to stop the film drive system including stopping the intermittent film feed at the optical film gate and extinguishing the light source illuminating the film.
