Summary:Disclosed is an image processing method employing a post processing technique that may eliminate flicker artifacts from captured video in real time. An example method involves receiving from an image sensor a sequence of input frames representing a scene and identifying and tracking a light source represented within the input frames. Flickering of the light source may be identified by detecting frame to frame color characteristic variation of a region representing the light source. A sequence of output frames may be generated with the flickering removed by selectively modifying image data of pixels within the region.
