The invention relates to a method and a device for altering the sharpness of the transient of a video signal in the form of a component, comprising at least two different filtering stages (S1 - Sn, Sv), of which the first filtering stage (S1 - Sn) comprises a filter (S1 - Sn) for processing the frequency, phase or structure of the video signal or a combination thereof, providing as outputs different processed signals (A, D, See, SMin, SMax), and the last filtering stage (Sv) comprises a selective filter (Sv) for selecting the output signal (OUT) of the device from at least two signals (A, See, D, SMin, SMax) the filtering stage (Sv), obtained as inputs and processed in one of the previous filtering stages. <IMAGE> |
