Abstract
Described is system for real-time automated exposure adjustment of a camera using contrast entropy. Multiple images are captured using an image sensor, where each of the images is captured at a distinct exposure value. A contrast entropy is determined for each of the multiple images. An image having the largest contrast entropy is selected among the images and output.
