To automatically detect and correct flickers in a video capture device, a frame number generator receives a plurality of frames and generates frame numbers. A storage device stores brightness values of partial pixels of a frame numbered 1. An extractor extracts brightness values of partial pixels of a frame numbered N. A difference summation device computes differences of the brightness values of the partial pixels of the frames numbered 1 and numbered N and sums up the differences to generate a brightness difference summation signal. A flicker detector detects a banding value in the brightness difference summation signal. A flicker corrector uses the banding value and the frame numbers to find a fixed frequency flicker effect in the frames, and generates a flicker correction signal when the fixed frequency flicker effect in the frames is found.
