    • A video processing device may compare a pixel or group of pixels of a current video picture to a pixel or group of pixels of a previous video picture. The video processing device may generate a motion vector for the pixel or group of pixels of the current video picture based on the comparison. The video processing device may determine an amount of filtering to be applied to the pixel or group of pixels of the current video picture. The video processing device may adjust the determined amount of filtering to be applied to the pixel or group of pixels based on the generated motion vector and based on a brightness value.
    • 视频处理设备可以将当前视频图像的像素或像素组与先前视频图像的像素或像素组进行比较。 视频处理装置可以基于该比较生成当前视频图像的像素或像素组的运动矢量。 视频处理设备可以确定要应用于当前视频图像的像素或像素组的滤波量。 视频处理装置可以基于生成的运动矢量并且基于亮度值来调整要应用于像素或像素组的所确定的滤波量。

    • Methods and systems for processing video information are disclosed herein and may comprise calculating a first two-field difference between a first plurality of pixels from a current field and a second plurality of corresponding pixels from an alternate field adjacent to the current field. At least one pixel from the current field may be deinterlaced based at least in part on the calculated first two-field difference. The first plurality of pixels and the second plurality of pixels may be aligned by adjusting a phase of at least one of the first plurality of pixels and the second plurality of pixels prior to the calculation of the first two-field difference. The first plurality of pixels may include a plurality of vertically adjacent pixels. The first plurality of pixels may comprise at least one luminance component. The alternate field may include a previous field and/or a next field. The first plurality of pixels and the second plurality of pixels may be filtered prior to the calculation of the first two-field difference.

    • A method for processing video information may include calculating a polarity change count (PCC) for a plurality of pixel pairs selected from a plurality of pixels from different fields utilizing a plurality of difference polarity values associated with the plurality of pixel pairs. At least a portion of the plurality of pixels from different fields may be deinterlaced based on at least the calculated PCC. The plurality of difference polarity values may be calculated for the plurality of pixel pairs selected from the plurality of pixels from different fields. At least one difference in amplitude of at least one of the selected pixel pairs may be calculated for the calculating the plurality of difference polarity values. The plurality of pixels from different fields may comprise a plurality of adjacent pixels from a plurality of woven fields.
