ABSTRACT:
A film projector for use with processed photographic film having magnetically recorded image information. The film projector has a body and a light source disposed in the body. The light source emits a collimated beam. A film holder is mounted in the body. The film holder is disposed to hold an individual frame of film in the beam. A projection lens system receives the beam propagated through the film. An optically transmissive digital display element is disposed in said body. A read-write unit is disposed to read annotation information from and write annotation information to the film in the film holder. A controller is operatively connected to the read-write unit and the display element. The controller modulates the display element responsive to the signal.
