Abstract
A scene-based image restoration system, method and apparatus calculates a plurality of restoration signals to be combined with a plurality of input signals to produce resultant signals that are substantially equal during a desired time interval. These scene-based image restoration systems and methods can use DC offset signals as scene restoration signals. To enhance results, faulty sensors in the system are detected, and the input signals from them compensated to produce better video images from the signals.
