Abstract
An apparatus and method for a three-dimensional luminance/chrominance (Y/C) seperation comb filter bank. The method and system consider the effect of motions in the temporal domain as the effect of edges in the spatial domain. The method and system apply a temporal filter to the section rule of edge location detection in the spatial domain. With this applications, the three-dimension comb filter bank can separate Y and C from each other freely without motion consideration. The method and system do not simply exploit the topology in the pixel phases. Rather, the method and system consider the Y/C comb filter to operate from the spectral viewpoint. Temporal filtering function is increased to better utilize the memory buffers of the three-dimensional filter. In so doing, balanced usage among the horizontal, vertical and temporal filter functions is achieved using the method and system.
