Abstract
The present state of film scanning in relation to the FCC standard is noted. The advantages of the coincidence of the film's movement with the vertical scanning blank are emphasized, especially with respect to the scanning of color films. A flying-spot color scanner for 16mm film without color registration errors has been designed with a pneumatic fast-action pulldown movement that advances the film within 1.14 ms. Image and sound are ready for transmission 0.2 s after the start. A take-up device with constant torque motors that provide a constant tension on the film, even during the acceleration and deceleration phases, is explained. The system permits film reversal for monitoring. The particular advantages and properties are summarized.
