ABSTRACT:
An image sensor formed on an integrated circuit is disclosed. The image sensor comprises an array of pixels including a plurality of bright pixels and a plurality of dark pixels. The image sensor also includes a dark exposure control circuit for controlling the exposure time of the plurality of dark pixels and a bright exposure control circuit for controlling the exposure time of the plurality of bright pixels.
