Abstract
A video apparatus includes a circuit for reducing noise in applied input video signals. The noise reducing circuit is provided with a temporal noise filter (S , LUT, M), a down-sample unit (D) for obtaining a spatial down-sampling of video signals (Vi) of subsequent pixels, these down-sampled video signals being supplied to the temporal noise filter (S , LUT, M), and an up-sample unit (U) for generating, in response to noise output signals obtained in the temporal noise filter (S , LUT, M), noise signals of the pixels, and a subtractor (S ) for subtracting the noise signals from the respective input video signals (Vi).
