ABSTRACT:
In a high speed video capture and display system including an N.sub.channels channel sensor for producing N.sub.channels parallel analog video signals, N.sub.channels signal processing channels for processing the analog video signals, each of the N.sub.channels signal processing channels including an analog-to-digital converter (ADC) having gain and offset which are controlled by controlling the common mode and differential voltages across each ADC ladder network; and a central processing unit for controlling the gain and offset by means of digital control signals; the method of calibrating the system to produce a uniform image comprising the steps of.
