Abstract
Methods and systems for 3D comb filtering of a video signal are provided. Aspects of the method may include generating a plurality of interpolated pixels for corresponding video samples for a first video frame, determining at least one direction of least bandwidth among the video samples and the interpolated pixels, and blending combing according to the determined direction of least bandwidth. A plurality of interpolated pixels for corresponding video samples may be generated in a first pixel line of the first video frame. The plurality of interpolated pixels in the first pixel line may be generated, so that each of the plurality of interpolated pixels in the first pixel line is one quarter cycle phase-shifted from a corresponding adjacent pixel in the first pixel line.
