ABSTRACT:
A digital video signal processing apparatus and method for adaptive spatio-temporal Y/C separation in multiple directions. In the digital video signal processing apparatus, an adaptive three-dimensional band pass filter (3D BPF) performs Y/C separation using local comb filtering/1D band pass filtering when the edge direction is fixed vertically/horizontally according to spatio-temporal local characteristics of an image using spatio-temporal filters. When the edge direction is not fixed horizontally/vertically, the 3D BPF performs 2D band pass filtering in all directions. Thus, the 3D BPF continuously carries out comb filtering, 1D band pass filtering and 2D band pass filtering according to the spatio-temporal local characteristics of the image.
