Electronic multi-imager

Claim 1

An electronic imaging system comprising: (a) a memory having n syllables of m words for storing a p level representation of a video image; (b) an N-lines per frame raster generator for producing N horizontal synchronization pulses per vertical frame synchronization pulse, wherein N is greater than either n or m; (c) data processing circuitry responsive to said synchronization pulses for converting said n syllables, within the time for vertical synchronization pulses to define a frame and in timed relationship to the horizontal synchronization pulses, into a plurality of video signals, each of which contains m signals and represents a line of m picture elements of the image; (d) a TV monitor having a screen on which an electron beam is incident for producing a display; (e) a deflection circuit responsive to said synchronization pulses for causing said beam to scan said screen and produce an N-line raster; (f) a modulation circuit responsive to said video signals for modulating the intensity of said beam during its scan; (g) an optical lens system for focusing said screen on a film plane, and (h) means for making p passes into the p level memory and for producing a video signal of unit amplitude on the ith pass for each word having a level greater than i-1.
