<p>A film correction system adjusts a relative position of film containing an area for information and a scanner of the film area. The system includes a film area scanner (58) for scanning the film area at a film plane (136). A film drive moves the film along the film plane. A film edge scanner (76) separate from the film area scanner scans a film edge in the film for determining a location of the film edge. A circuit is coupled to the edge scanner for changing a relative position of the film area scanner and the film area. The film edge scanner is a flying spot scanner, and the apparatus includes signal processors (158) for processing the sprocket information. The system may be retrofit to an existing telecine apparatus. A separate coil may be used to provide deflection of a flying spot scanner used to scan the picture information on the film.</p> |
