Abstract
A system for compensating for film flutter in a motion picture film projector during projection of a motion picture film comprising multiple film image frames is described, the system comprising sensing the position of film image frames in a film gate of the projector relative to the focal plane of the projection lens assembly of the projector as the film image frames are being projected, and correcting the position of the film in the film gate of the projector or the position of the focal plane of the projection lens assembly to reduce the distance between the film image and the focal plane of the projection lens assembly as the film image frames are being projected, wherein the correction of the position of an individual film image frame in the film gate or that of the position of the focal plane of the projection lens assembly during projection of the individual frame image is based on the actual sensed position of the individual film image frame in the film gate, or on the position of a previously projected film image frame which was sensed as it was being projected.
