Abstract
A method for controlling the black level of an input signal and a video apparatus using the same are disclosed. The video apparatus includes a histogram analysis module (701) for decoding a video signal of each frame input to the video apparatus to a luminance signal and analyzing a histogram of the decoded luminance signal, a black level detection module (702) for determining a type of the video signal according to a result of the histogram analysis, and a black adjustment module (703) for adjusting a black level of the video signal according to the type of the video signal.
