Abstract
A film video player for sensing photographic images having a given resolution to produce a standard video signal having a lower resolution, includes a zoom lens for selectively varying the magnification of the film image with respect to the image sensor and means for selectively translating the film image vertically and horizontally with respect to the image sensor, whereby the available resolution of the film image is more effectively utilized by the film video player.
