  • Telecines with simultaneous scanning of a plurality of frames
    Patent number: 5557322
    Abstract: A continuous-motion flying-spot telecine has twin objective lenses (13,14) which provide beams to scan two adjacent film frames simultaneously. Two sets of light detectors (16,17) are provided, one for each frame being scanned. The detector outputs are applied to a multiple frame store (23; FIG. 2). The scans can take place at half the normal speed, while a conventional rate signal is read out of the store. Problems caused at high frequencies as a result of afterglow on the CRT (10) can thereby be substantially reduced.
