Abstract: An Automatic Exposure Control (AEC) regulates the operation of the digital camera sensor array. The acquisition of images and videos is optimized through having the automatic exposure control lock the exposure time of the photo-sensor array prior to performing any digital processing on the acquired image. The automatic exposure control determines the amount of exposure through moving the median brightness to the center of the dynamic range.
