| 摘要 | 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. | ||

| 主权项 | 1. A video signal processing apparatus comprising: a video signal processing unit configured to process an input video signal and output an output video signal; a temporal feature detecting unit configured to detect a temporal feature from the input video signal; a smoothing unit configured to smooth the temporal feature by filtering using a smoothing filter configured to reorder values of the temporal feature in accordance with a dynamically adjustable order, and selectively output values of the smoothed temporal feature; and a controlling unit configured to control processing performed in the video signal processing unit in accordance with the smoothed temporal feature, wherein: the smoothing unit dynamically adjusts the dynamically adjustable order in accordance with an attribute of the input video signal. | ||
