Abstract (en)
[origin: WO9001844A1] An abstract sensor array (10) includes adaptive sensitivity control circuitry (12) for obtaining multiple outputs at different exposure levels. These are combined to yield an output with enhanced dynamic range. This enhanced dynamic range may be reduced in a manner which preferentially retains edge information in order to maintain high contrast.
