  • Image stability in telecines
    Patent number: 5619258
    Abstract: A telecine uses a flying-spot scanner to derive video images from a film. A scan control circuit is used to control the scan of the flying-spot to introduce special effects. Pairs of successive images may be misaligned and a motion vector estimator is used to detect the amount of misalignment. This produces a shift vector for an image stabilizer to shift one of the images of a pair. The motion vector estimator also receives data from the scan control circuit relating to any special effect in the images and corrects the shift vector in dependence on this.
