Patent ID: 8139157

Claim:
A video display apparatus comprising: a luminance information detector for receiving a video signal divided into frames, creating a luminance histogram from one frame of a luminance signal derived from the video signal, and generating luminance information from the luminance histogram; a content classifier for classifying the content of the one frame according to the luminance information generated by the luminance information detector and generating a first classification value; a content analyzer for analyzing the first classification values output by the content classifier for a plurality of frames to obtain a second classification value; a saturation information detector for receiving the video signal, creating a color saturation histogram from at least one frame of a color saturation signal derived from the video signal, and generating color saturation information from the color saturation histogram; a scene change detector for detecting scene changes in the video signal and generating a scene change detection signal; a correction controller for outputting a video correction control signal and a display control signal, based on the second classification value, the scene change detection signal, and the color saturation information; a video corrector for performing a video correction on the video signal, based on the video correction control signal; and a display unit displaying a video picture according to the video signal output from the video corrector and performing display control according to the display control signal.
