Abstract: Separation of luma and chroma in a video. In an embodiment, values on a current line of the sampled video signal, at ¼-period intervals, are compared with values on a previous line of the sampled video signal, at ¼-period intervals. Values on the current line of the sampled video signal are compared to values on a subsequent line of the sampled video signal. This gives information about the vertical frequency content. Values on the current line are compared with values having the same chroma phase on the same line to provide information about horizontal frequency content. The data of vertical and horizontal frequency logic are used by the decision logic to determine the appropriateness of combing based on these comparisons. If combing is not appropriate, the signal is bandpass filtered instead of combed. The low-pass and combing filters are applied to the original signal, not an interpolated or resampled signal.

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.

Abstract: Methods and systems for time constant for a 3D comb filter of a video signal are provided. Aspects of the method may include assigning a weight to a 3D comb mesh value. Combing may be blended according to the assigned weight of the 3D comb mesh value. The weighted 3D comb mesh value may be accumulated in order to generate accumulated mesh value. If the accumulated mesh value exceeds a saturation value, the accumulated mesh value may be reduced to the saturation value. If the 3D comb mesh value is smaller than a first threshold value, the accumulated mesh value may be reset to zero. A multiplier may be generated according to the accumulated mesh value. If the accumulated mesh value is between a second threshold value and a third threshold value, the multiplier may be blended.
