adaptive analog video signal conditionerThis paper presents an adaptive analog video signal conditioner. This system supplements conventional irises and automatic gain controls to condition video signals for digitizing with a uniform analog-to-digital converter. Employing two degree of freedom, this circuit adjusts an analog gain and analog offset to increase the average information content of digitized images as defined by an entropy measure. The globally near-optimized implementation tracks smoothly to adapt to changing scene conditions.
