Digital reproduction of variable density film soundtracks

摘要

Restoration of audio information embodied on a soundtrack of a motion picture film advantageously occurs by scanning the film with a beam of light to capture the image in the form of a digital signal via an imager. The digital signal undergoes storage in a storage mechanism ( 300 ) and subsequent processing via controller. The controller applies one or more statistical processing algorithms to eliminate deficiencies and to enhance the quality of the audio embodied in the soundtrack.
