ABSTRACT:
A film video player apparatus for sensing a film frame image to produce a video signal comprised of standard video fields, includes means for selectively changing the magnification of the film frame image with respect to the video display (zoom) and for displacing the film frame image horizontally and vertically with respect to the video display (scan). The film video player apparatus is provided with a control system comprising means for coordinating zoom and scan so that the video display is always filled with the film image. The control system further includes means for returning the zoom to normal magnification when a new film frame image is selected for display. The video player apparatus blanks the video signal during film advance, but continues to produce a video signal for display while zooming and scanning.
