Abstract
Abstract Audio to be recorded in a photographic film camera in association with individual exposed frames is first digitized and stored in a temporary storage memory in the camera allowing playback through a speaker mounted in the camera to permit playback review and editing, as needed. When the film is advanced in the camera to the next exposure frame, the digital audio signal is recorded on a magnetic layer formed on the film. At the photofinisher, the digital audio signal is read and converted to suitable encodement format, such as bar code or binary coded blister marks which are impressed on the photoprint for subsequent playback.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
186 words
Photographic film system with audio recording and playback comprised of a photographic film camera adapted to receive film having a magnetic recording layer thereon, said camera have audio transducer and signal conversion means for converting audible sound to a digital signal, temporary storage means for storing said digital audio signal in the camera and magnetic recording means for recording said stored digital signal on said film magnetic recording layer and photofinishing apparatus for producing photographic prints from latent images exposed onto said film in the camera, said photofinishing apparatus including magnetic read means for reading the digital audio signal recorded on the film magnetic layer, means for converting said read digital audio signal into a predetermined encodement format and means for impressing said encodement format onto said photographic prints for subsequent audio playback; the system characterized by: a self-contained hand-held scanner playback device independent of said camera including an optical sensor, memory and audio reproduction unit adapted to scan said encodement format on said photographic prints to generate digital audio data signals for storage in said memory and for subsequent playback independent of said photographic print.
