Abstract
A method for suppressing banding and rolling flicker in video acquired by a video camera. The method comprises acquiring a plurality of video frames and assessing an amount of rolling flicker in the plurality of video frames. The method further comprises configuring the video camera to quiet banding and rolling flicker responsive to periodic illumination at a first frequency if the amount of rolling flicker is above a threshold, and, configuring the video camera to quiet banding and rolling flicker responsive to periodic illumination at a second frequency if the amount of rolling flicker is below the threshold.
