  • Device and method for reproducing photographic sound recordings
    Patent number: 7400821
    Abstract: For a reproduction of optical sound information in a double variable-area track (DZ) an optoelectronic converter device scans the optical sound track of a film. The converter device generates a digital image signal for buffer storage in the memory of a program-controlled data processing device. The data processing device derives the profile of the two edges of the double variable-area track from data values of the buffer-stored image signal. Audio data for a sound reproduction are generated using data about the edge profile determined.

  • Device and method for reproducing photographic sound recordings
    Publication number: 20030165087
    Abstract: For a reproduction of optical sound information in a double variable-area track (DZ) an optoelectronic converter device (1, 2, 4, 9 to 13) scans the optical sound track (3) of a film (4). The converter device (1, 2, 4, 9 to 13) generates a digital image signal for buffer storage in the memory (19) of a program-controlled data processing device (15). The data processing device (15) derives the profile of the two edges of the double variable-area track (DZ) from data values of the buffer-stored image signal. Audio data for a sound reproduction are generated using data about the edge profile determined.
