Abstract
An apparatus for playback of an analog optical sound track on a film includes a transport for transporting the film past a scanner that generates a digital image signal representative of the analog optical sound track. The digital signal represents the optical signal as gray scale values with a range of greater than one bit. A processor processes the digital image signal for displaying and assessing a result while adjusting a threshold that determines the representation of gray scale values with one bit of resolution.
