Abstract
A video signal processing method includes the steps of processing an input video signal and outputting an output video signal, detecting a temporal feature from the input video signal, smoothing the temporal feature by filtering and outputting the smoothed temporal feature, and controlling processing performed in the processing step in accordance with the temporal feature smoothed in the smoothing step. In this method, the smoothing step switches a characteristic of the filtering in accordance with the attribute of the input video signal.
