Abstract
The methods of converting the 24 frames/sec film standard to the 30 frames/sec television standard are discussed. The disadvantage of using storage-type devices is brought out in order to show the need for a flying-spot scanner in televising film in color. The reasons for choosing the jump-scan method in the Motorola scanner are given with emphasis on the advantage of the large optical aperture realized with this method. This is possible since no moving optical parts are needed between the tube and the film and the full opening of the lens can be used. The various factors affecting registry both in time and space are enumerated. The solutions used to minimize the errors and the final results obtained are given. The use of a signal derived from the leading edges of the sprocket perforations to control the position of scan on the tube face to minimize bounce is described in detail. The use of this signal for continuous correction of film shrinkage is also shown. Other features of the scanner to be described are the anastigmatic deflection yoke and single-control adjustable gamma.
