Abstract
In a device for correcting color distortions due to aging processes of films when scanning the films, video signals generated by the scanning of selected picture areas extending over the picture width can be fed to a filter. The filter is designed to suppress noise components and picture content. Output signals of the filter can be fed as correction signals to a correction circuit for the video signals generated by the scanning of the film. The filter may be formed by applying an autocorrelation function to the video signals of the selected picture areas.
