An apparatus for generating video signals from a photographic image previously recorded on film (a cine-video system) which includes a film transport mechanism for advancing or rewinding the film in order to position a film frame at a film gate for projection, an image projector which detects when a film frame is positioned at the film gate and projects an illuminated image of that frame, a video pickup system which receives the image and generates a video signal which represents it, and an output circuit which produces a resultant output video signal. A window generating capability provides for optional enhancement of the video signal within a user-selectable range of video signal values. One or more cursors may be superimposed on the video image, and measurements to determine the distance between two such cursors may be performed. A &ldquo;Hi-line&rdquo; output video signal containing twice the standard number of scan lines is generated, as is a NTSC standard output video signal and a &ldquo;D-2&rdquo; standard digital output video signal. Advantageously, the cine-video system is implemented as a digital system, under the control of a programmable, digital signal processor.

Apparatus for generating video signals representing a photographic image previously recorded in a frame on a photographic film-type medium

Film transport apparatus for a cine-video system in which video signals are produced from film that is driven between supply and take-up reels. The film, which may be wound in A or B configuration on each reel, is threaded automatically about a film drive mechanism which transports the film from the supply reel, through a film gate to the take-up reel. Tensioning apparatus imparts tension to the film at the entry and exit of the film gate which, during the threading operation, causes the respective reels to rotate before film actually is transported therebetween. The direction in which each reel rotates to unwind film therefrom when tension is imparted serves to identify whether the film is wound in A or B configuration. Advantageously, a programmable processor controls the film transport speed in response to a user-actuated knob; and this same processor serves to detect when the film approaches its end on the supply or take-up reel.

Apparatus for selectively generating video signals representing photographic images previously recorded in a film on a photographic film-type medium includes an image pickup device which produces video signals in response to a light image of the projected photographic image, a window generating device which generates a window having a range of video signal values in response to a user input, a processor which suppresses the produced video signals having values outside the generated window, and an enhancer which enhances the produced video signals having values within the generated window.
