Abstract
A film video player (10) has film gates (14, 15) for mounting photographic film (F, F') an imager has a lens (L) for projecting at least a portion of a film frame image from the film on to a sensor (S). The sensor converts an image to a video signal for video display. A zoom carriage (25) changes the magnification of the image with respect to the film frame image. A scan carriage (65) translates the sensor with respect to the film frame image in one axis, and a gear assembly (90) translates the sensor along a perpendicular axis as well as rotating it.
