Abstract

1409153 Film scanner BRITISH BROADCASTING CORP 8 April 1974 [19 April 1973] 19070/73 Heading H4F Imperfections, such as dirt or scratches, on a film 12 in a telecine playback machine are detected by detecting the amount of light from flying-spot scanner 10 which is scattered by the film. The thus produced signal, derived by photo-sensitive devices 22 and pulse shaper 30, controls a switch 28 to insert, on detection of an imperfection and in place of the signal from photoelectric cells 14, a grey level or the output of a delay device 26. Each photo-sensitive device 22 is associated with an optical light guide or fibre optic rod. Devices 22 may be provided on one or both sides of film 12.
