APPARATUS AND METHOD FOR CONTROLING LENS

摘要

PURPOSE: A lens control device and a method thereof are provided to maintain reference brightness by complexly controlling a plurality of image devices having different stopping voltages. CONSTITUTION: A brightness calculation unit (430) accumulates and collects more than one brightness values for more than one image signals inputted from a light receiving device. More than one adjustment control units (440) adds or subtracts each of the brightness values. An output unit (450) sums the added or subtracted values and outputs the value. The brightness calculation unit accumulates each of the brightness values. The brightness calculation unit calculates the average brightness value by dividing the accumulated brightness values by the number of the image signals.
