Abstract
A method for automatically detecting, eliminating and replacing flash frames in digital video utilizes the detected flash frames to categorize and tag the surrounding frames as a relevant area of the digital video. The flash frame is detected when acquiring digital video during capture, the flash frame is replaced with a newly-constructed frame that is interpolated based upon surrounding frames and then, using the detected flash as the timestamp, the frame is tagged.
