ABSTRACT:
A zero-time-delay video processor circuit includes reduction circuitry for eceiving a digital image input and providing a reduced and Nyquist acceptable digital image output signal. A controlled write/read memory connected to the reduction circuitry provides the digital image output. A digital estimator is connected to the reduction circuitry for providing an estimated gain signal. A gain corrector circuit is connected to the controlled write/read memory for compensating for errors in the estimated gain. A signal indicative of the true or required gain is provided to the digital estimator and to the gain corrector.
