Abstract
In the course of each horizontal blanking interval, the spot of the flying spot tube is deflected in the vertical direction causing an image of the spot to meet a perforation of the film in fixed space relationship with the film frame being scanned. A pulse signal, generated when the image of the spot reaches the concerned perforation, is used as an input signal for the circuit delivering an error signal for controlling the vertical deflection of the tube.
