Patent DE-3167749-D1 (DE)
Title: Method and apparatus for recording and playing back continuous-play video signals together with stop-motion video and audio signals
Inventor: GOLDING SCOTT MITCHELL
IPC: H04N5/92
Filed: 1981-10-29
Granted: 1985-01-24
Abstract: An improved method and apparatus for recording and playing back a video signal on a video disc, such that selected video frames can be played back in a stop-motion fashion, with accompanying audio. Each stop-motion video frame is recorded on a single recording track on the disc, and an associated digitized stop-motion audio signal is combined with a continuous-play video signal and recorded on a plurality of preceding tracks. During playback, the tracks recording the continuous-play video signal are first scanned, to recover and display the continuous-play video frames, and to recover and enter into a memory the digitized stop-motion audio signal. The track recording the corresponding stop-motion video signal is then scanned, in a repeated fashion, to provide a stop-motion display of the video frame, while the stop-motion audio signal is extracted from the memory and converted back to its original analog format, for playback along with the stop-motion video frame.

Title: Method and circuit for contrast enhancement
Inventor: GAST UWE
IPC: G03F1/00
Filed: 1982-08-27
Granted: 1987-01-08
Abstract: A method and an apparatus are provided for contrast intensification in the reproduction of masters in the field of electronic image processing by engraving devices and scanners. In the image-point-wise, opto-electronic master scanning, two outer field signals are obtained in addition to the image signal by scanning a first outer field and a larger, second outer field. A first differential signal and a second differential signal are generated from the image signal and the outer field signals and a third differential signal is generated from the two outer field signals. The first differential signal is combined with at least one of the other two differential signals to form an auxiliary signal which is added to the first differential signal in order to obtain a correction signal. The correction signal is then superimposed on the image signal for the purpose of contrast intensification. By employing a second outer field signal, it is particularly the disturbing edges around hard master contours which are avoided.

Title: Device for developing microfilm
Inventor: STAUDE ECKHARD
IPC: G03D3/02
Filed: 1982-10-22
Granted: 1989-04-20
Abstract: An apparatus for the development of microfilm passes film successively through different work stations, such as the developer bath, fixing bath, preliminary washing bath, second washing bath and a drying stage. The film moves in a horizontally arranged track with the aid of a motor driven pair of rolls. The apparatus is characterized by a liquid circulation system in which each vessel supplying a liquid station with a liquid and designed as a transport container is equipped with a supply line and a suction line. The suction line moves the liquid to a bath by means of a liquid pump and by way of pressure lines through a heating means. A bath may be associated with each work station. In the bath the liquid is sprayed against the bottom side of the film travelling in the horizontal direction and is returned through a liquid and film guiding body and the supply line into the vessel.
