Abstract
Methods and systems for 3D bidirectional comb filtering of a video signal are provided. Aspects of the method may include generating a plurality of interpolated pixels for a current line, a next line and a previous line in a current frame. A plurality of interpolated pixels may be generated in a previous frame, which corresponds to the interpolated pixels in the current frame. A plurality of interpolated pixels may be generated in a next frame, which corresponds to the interpolated pixels in the current frame. At least one direction of least bandwidth may be determined among at least a portion of all the generated interpolated pixels and true pixels in the current frame. Combing may be blended according to the determined at least one direction of least bandwidth.
