Abstract
In a flying spot telecine used to generate video signals by scanning a film, the scanning raster is adjustable angularly relative to the film being scanned. The output video signal hence represents the image on the film but angularly displaced relative to the orientation of the film itself. Using this method angular and rotational picture effects can be generated without the need for expensive computer memory or complex processing of picture information. The method can be applied to produce similar angular and rotational effects in a film writer. In such a system, unexposed film is repeatedly scanned by the flying spot scanner, the beam of which is modulated in turn by R, G and B video signals.
