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.

Abstract: The invention relates to a film scanner comprising at least a first frame store (5) for storing the digitized pixel data of a scanned film frame, and at least a control device (6) for reading the relevant pixel data of a frame section of the stored film frame from the first frame store (5). To generate output frames in an arbitrary format and resolution, which may be used, for example for further processing in real-time multimedia applications, the control device (6) in the film scanner is provided with an arithmetic-logic unit for generating an output frame in a given size, a given aspect ratio and a given number of pixels per output frame line and lines per output frame by computing new pixels. By determining the format, particularly the resolution, for the output frame already during the scanning process, a direct further processing on computer panels or in multimedia applications is made possible. The transfer rate and the capacity required for storing the data are also reduced in this way.

Abstract: A method and an arrangement for manufacturing a high-resolution digital master for filing cinematographic films and their conversion into different TV and multimedia standards, in which the overall picture and sound information associated with the cinematographic film is high-resolution scanned, digitized and stored. For creating a high-quality electronic duplicate of a film master for the purpose of document-secure filing or for manufacturing different TV and multimedia versions, picture and sound data prescriptions derived from the film for processing steps and parameters associated with the corresponding film frames are additionally stored.
