摘要： Noise-reduced pixels may be generated using outputs of filtering via a first filter and/or a second filter, and/or a blend of both outputs. Blending a current pixel and an output of filtering of current pixel via the first filter may generate a first blended current pixel. Filtering via the first filter may be based on the current pixel, a previous collocated pixel, and a next collocated pixel. Blending the current pixel and an output of filtering of current pixel via the second filter may generate a second blended current pixel. Filtering via the second filter may be based on the current pixel and a collocated pixel of the previous second blended video image or of the previous filtered output video image. Blending the first blended current pixel and the second blended current pixel using an adaptive blending factor may dynamically generate a filtered output pixel.

摘要： A video processing system may implement a video scaling algorithm using interpolation based on polyphase filtering. A video or graphics scaler may be utilized to scale luma, chroma, and/or alpha information in a video image. The scaler may comprise a first polyphase sub-filtering with zero phase shift that generates an in-phase filtered output from an input video image and a second polyphase sub-filtering that generates an out-of-phase filtered output from the input video image. The video scaler may also comprise an interpolator that may generate a scaled video image based on the generated in-phase and out-of-phase filtered outputs and a scaling factor. The scaling factor may be determined based on an input video size (M) and a desired output video size (N). The interpolation of the generated in-phase and out-of-phase filtered outputs in the video scaler may be implemented by utilizing a Farrow structure.

摘要： Current output pictures of video data are generated utilizing a motion compensated (MC) blended picture and a corresponding non-MC blended picture of the video data. Windows of picture data from a first picture and MC windows of picture data from a MC previously output picture may be partitioned. The partitioned widows are compared and the first picture is blended with the MC previously output picture based on the comparison to, for example, reduce noise and prevent motion trail artifacts. Non-MC windows of picture data from a MC or non-MC previously output picture may be partitioned and compared with the windows of picture data from the first picture. The first picture may be blended with the MC or non-MC previously output picture based on the comparison to reduce motion trail artifacts. A blending factor is determined and utilized to blend the blended pictures to reduce noise and prevent motion artifacts.

摘要： In a video processing system, a motion compensated de-interlacer (MCDI) may read four consecutive fields of interlaced pixel data that may comprise video and/or film content. The MCDI may convert a current field of interlaced pixel data to a de-interlaced frame of pixel data. Motion may be estimated between two of the fields with up to ¼ pel precision. A motion vector may be determined based on searching a field of the same polarity. The motion vector may be scaled with up to ¼ or ⅛ pel precision for a field of an opposite polarity. A level of validity may be determined for the motion vector and/or the scaled motion vector. A motion compensated (MC) pixel value may be interpolated for a current field based on a second field comprising an opposite polarity. The MC interpolated pixel value may be blended with a pixel value determined based on another method of de-interlacing.

A filtering mode may be selected to generate noise-reduced pixels using FIR, IIR, or a blend of FIR/IIR filtering.

The FIR filtering may be based on the current pixel, a previous collocated pixel, and a next collocated pixel. Blending the current pixel and an IIR-filtered current pixel may generate a second blended current pixel. Blending the first blended current pixel and the second blended current pixel using an adaptive blending factor may dynamically generate a filtered output pixel. The IIR filtering may be based on the current pixel and a collocated pixel of the previous second blended video image or of the previous filtered output video image.
