Abstract:
A film scanner for the optical scanning of a motion picture film having a sequence of a plurality of image regions and at least one row of a plurality of perforation holes in the longitudinal direction, in particular a motion picture film of the type 16 mm or 35 mm, comprises an image sensor for the detection at least of a respective image region of the motion picture film to generate a corresponding scanned image. The film scanner further comprises an evaluation unit for the evaluation of the scanned image to generate an image steadiness correction signal. The image sensor is made for the additional detection of only a respective part region of perforation holes in the environment of the detected image region of the motion picture film, with the evaluation unit being made to determine a position of the detected part region of at least one perforation hole. The evaluation unit generates the image steadiness correction signal on the basis of the at least one determined part region position.
