    • A video display apparatus generates luminance information for individual frames of a video signal from histograms of the luminance component of the video signal, and classifies the content of the video signal on the basis of this information. Color saturation information is also generated from color saturation histograms, and scene changes are detected. Video correction parameters and display control parameters are derived from the content classification and color saturation information. The video signal is corrected according to the video correction parameters, and displayed according to the display control parameters. Display characteristics suitable for the video content are thereby obtained. The parameters are changed when a scene change is detected, so that the viewer is not disturbed by the change in video display characteristics.
    • 视频显示装置从视频信号的亮度分量的直方图生成视频信号的各个帧的亮度信息,并根据该信息对视频信号的内容进行分类。 颜色饱和度信息也是从颜色饱和度直方图生成的,并且检测到场景变化。 视频校正参数和显示控制参数是从内容分类和色彩饱和度信息中得出的。 视频信号根据视频校正参数进行校正,并根据显示控制参数进行显示。 从而获得适合于视频内容的显示特性。 当检测到场景变化时,参数被改变,使得观看者不受视频显示特征的变化的干扰。
