ABSTRACT:
The translation of an optical image into video signals by a video sensor illuminated by the optical image is adjusted by illuminating the sensor at a first level of light intensity sufficient to provide the video signals at maximum amplitude while adjusting the amplitude of the video signals to a first level, and then illuminating the sensor at a second reduced level of light intensity while adjusting the black level of the video signals so that the black level is at least equal to the amplitude of the signals produced by the sensor in the absence of illumination.
