Abstract
An improvement in an analog-to-digital converter wherein a series string of capacitors is utilized to generate reference voltages for the comparators of the converter. The digitized output of the converter is then used to control a predetermined timed discharge from a selected one of the series string of capacitors. The converter, as described, may be used in a video system as an adaptive contrast enhancement mechanism.
