发明名称 Cine film-video scanner system
摘要 To suppress display of film splices, defects in the film, fade, dissolve, or torn perforation openings upon scanning a film for video reproduction, splices and defects are recognized, and transmission of the frames which include these splices and defects to a memory connected to a film scanner is inhibited, the memory being repetitively read-out to obtain sequential output signals in accordance with the television standard of previously properly scanned frames. Splices and the like can be recognized by an automatic recognition sensor (19), for example sensing optical density, a capacitative sensor or the like; and/or defects can be recognized visually by an operator, and the respective defective or spliced frames entered in a film splice frame memory (23), which, subsequently, inhibits transmission of the respectively spliced or defective frames to the memory (12) receiving the scanned video signals. Since frequently splices occur upon scene change, an automatic scene change recognition network (27) may be used to recognize splices, and to inhibit recording in the memory of frames including the scene change, and hence the splices.
