Abstract
A method is described for the determination and automatic correction of horizontal and vertical errors in image steadiness for continuous raster scanning of film, using an image memory. By means of the vertical image steadiness error signals the beginning of scanning of the first line of a new film frame and the start of writing of video signals for the first line of this film frame are determined. Output of the video signals for at least one stored image is synchronous with the studio timing signals so that it can be read out using standard studio horizontal image steadiness and vertical timing signals. By means of the horizontal error signals the start of the scanning of a new line is displaced for a stored image in relation to the start of the reading of a new line.
