ABSTRACT:
A film scanner scans a frame of film three times by reciprocating a clapper gate assembly (160) holding the film (50) past a solid state line array sensor (210). Successive scans are in an opposite sense to the previous scan and R,G,B filter wheel (40) is placed in the optical path and advanced for each scan so that separate high resolution R,G and B scan are produced which can be combined to form a high resolution video signal.
