An apparatus and method of extracting a sync signal from an analog composite video signal includes a controller to decide whether a horizontal sync signal in the analog composite video signal is a distorted abnormal signal, and extracts the horizontal sync signal from the composite video signal using a separate counter if the analog composite video signal is the distorted abnormal signal A sync signal can be precisely extracted from the distorted abnormal signal. Therefore, an overall system synchronization of the apparatus can be stable, and distortions in output images can be prevented.
