摘要
A video signal producing a raster-scanned image is processed in real time to enhance high frequency characteristics of the image generated by the signal, with the enhancement performed according to a local adaptive process implemented in an apparatus including one or more two-dimensional higher-order filters. Each filter provides a signal corresponding to a statistical measure of the raster image at a point in the image centered in a local area. In each case, the measure is a function of characteristics of the image within the centered area. Each filter is synchronized with the video signal to provide its respective statistical signal substantially in real time and in phase with the input video signal.
