DIGITAL REPRODUCTION OF OPTICAL FILM SOUNDTRACKS

摘要

An apparatus for playback of an analog optical sound track comprises a transport means for transporting a film including an analog optical sound track. A scanning means generates an image signal of only the analog optical sound track as gray scale values. An alignment means aligns the scanning means such that the image signal of only the analog optical sound track substantially fills a width of the scanning means. A processor processes the image signal to form an audio output signal.
