Abstract
This invention relates to a method and apparatus for improving the reproduction of a television picture derived from a cinema film by a telecine apparatus during a period of panning and/or tilting in the scene recorded on the cinema film. The improvement is achieved by shifting the scanning raster of the telecine apparatus in respect of at least selected television fields during the panning or tilting period in such manner that during a series of consecutive television fields an image of an object moving across the television picture is reproduced in the television picture in a greater number of positions along its direction of movement than the number of film frames from which the series of consecutive television fields is derived.
