摘要： A video processing apparatus including a display comprises a filter for receiving a video signal containing video information and ancillary information related to the video information and having a predetermined frequency. The filter passes a component corresponding to the frequency of the video signal. An ancillary information extractor extracts the ancillary information from the video signal passed by the filter. A video processor processes the video signal so that the ancillary information extracted by the ancillary information extractor is displayed on the display. The video processing apparatus is able to enhance the reliability of ancillary information extraction by removing the influence of noise.

摘要： A dynamic gain adjustment method and apparatus based on brightness are provided. The dynamic gain adjustment method and apparatus amplify or attenuate high frequency components of an input video signal by dynamically varying a gain that is applied to a peaking algorithm block for picture quality improvement in a video processing device, such as a digital television, based on an average picture level (APL) of the input video signal. The gain can be dynamically adjusted when the APL of the input video signal is high or low, and thus saturation of the video signal during the operation of the peaking block can be prevented.

摘要： A video signal processing apparatus and video processing method are provided, which can reduce an influence of noise and enhance fineness of the image. A signal division unit divides a video signal into a low frequency component and a high frequency component of the video signal. A signal eliminating unit eliminates a component within a magnitude range of noise from the high frequency component of the video signal output from the signal division unit. A signal combining unit combines the low frequency component of the video signal output from the signal division unit and the high frequency component of the video signal from which the component within the magnitude range of noise is eliminated.
