Abstract
A system for enhancing the dynamic range of an imaging signal includes a sensor for viewing a scene having a wide dynamic range and generating a digital image signal of the scene which is received by an attenuator for selectively attenuating the digital image signal. A demultiplexer is included in the system for receiving the digital image signal into at least a first gain signal and a second gain signal wherein a combiner receives the first and second gain signals and produces a composite image signal with minimal saturation. A normalizer may also be provided for receiving the composite image signal and adjusting it to a viewable range dynamic video output signal.
