Optical image modifier for distortion or other compensation

Abstract

Abstract An optical image modifier is disclosed as comprising an adjustable reference clock signal generator which timely enables a sawtooth signal producing adjustable ramp generator and a voltage controlled frequency generator controlled thereby for producing a programmed frequency modulated signal which is, in turn, supplied to a preprogrammed signal generator and distributor. In response to said programmed frequency modulated signal, said generator-distributor produces and distributes a plurality of control signals to a charge coupled device - containing, in this particular instance, image sensors, transfer gates, one or more shift registers, a control gate, and an enabling amplifier - for the purpose of controlling the modification of any optical images (or other signals) sensed, transduced, stored, and read out thereby in accordance with a predetermined program that was effectively preset by the appropriate adjustments of the aforesaid reference clock and ramp generators. A low-pass filter or integrator may optionally be employed to smooth the output signal from said charge coupled device prior to its being displayed or recorded by any suitable readout.
