  • Telecine scanner including means for determining and automatically correcting vertical and horizontal picture steadiness errors in continuous-motion film drive scanning
    Patent number: 5734171
    Abstract: A telecine scanner includes a device for determining and automatically correcting vertical and horizontal picture steadiness errors (film weave correction) during continuous-motion film drive scanning. To perform an optimum film weave correction, correction signals are derived from photosensors (11 and 13) arranged in the area of the film gate and scanning the sprocket holes during the entire scanning period of each film frame. The photosensor (11) provided for vertical correction includes a plurality of photoelements arranged transversely to the film drive direction and substantially corresponding to the number of television lines per film frame. The photosensor (13) provided for horizontal correction includes a plurality of photoelement sectors (14 to 21) arranged along the film edge, the photoelement sectors being smaller than a sprocket hole.
