Abstract
Abstract There is disclosed a system wherein a film is moved past the faceplate of a cathode-ray tube. The scanning raster of the cathode-ray tube is skewed in response to the amount of movement of the film by means of apparatus which generates signals as the film moves. The signals are used to longitudinally offset each scanning sweep (line) of the raster. Means are also provided to start and stop film movement if the offsetting exceeds certain ranges. There is further disclosed a pin cushion correcting system wherein the slope of a sawtooth waveform signal used to generate a scanning sweep is controlled by means of circuits responsive at least to the amplitude of the sawtooth waveform signal.
