Abstract :
The last few years have seen explosive growth in the market for inexpensive cameras embedded in mobile electronic systems such as cell phones. These embedded cameras often use CMOS image sensors with an electronic rolling shutter. Rolling shutter image sensors are susceptible to highly objectionable artifacts caused by flickering AC lighting fixtures. Flicker artifacts can easily be avoided if the AC power frequency is known. A technique for automatically detecting flicker is presented.
