A Pan-Scan System for Printing Motion Pictures for Television from Anamorphic Negatives

Until a few years ago, prints for TV from anamorphic negatives were made from scanned internegatives obtained from an interpositive. A printer has been developed which can pan and scan directly to color positive from the original negative, at the same time that other effects are inserted. The equipment can also be applied to the production of reversal internegatives. Because of the illumination optics involved, and the unusual length of the deanamorphosing lens, it has been found advisable to leave the copy lens on the optical axis, and to accomplish the scanning by moving the receiving head back and forth. Since the printing is carried out using a wet process, it is necessary to scan “on the fly,” i.e., without stopping the printer. To this end, the 35mm film movement is swung within the space of the positive head or camera. A single sprocket, located on the optical centerline, is employed to act both as the feed and the take-up.
