Abstract
Method and system for an adaptive three-dimensional Y/C comb filter are disclosed. A composite TV signal is input into a color decoder. A first decision-making module determines if an edge passing through a current sample pixel is a color or colorless edge. If the edge is colorless, a second decision-making module determines if the edge is lying vertically, horizontally, or temporally. Once the second decision-making module determines the direction in which the edge lies, the module applies an appropriate Y/C comb filter to the input composite TV signal. If the edge is a color edge, a third decision-making module determines if the edge is lying vertically, horizontally, or temporally. Once the third decision-making module determines the direction in which the edge lies, the module applies an appropriate Y/C comb filter to the input composite TV signal.
