First Claim
Patent Images
1. A method, comprising:
- in a video processing device;
comparing a pixel or group of pixels of a current video picture to a pixel or group of pixels of a previous video picture;
generating a motion vector for said pixel or group of pixels of said current video picture based on said comparison;
determining an amount of filtering to be applied to said pixel or group of pixels of said current video picture; and
adjusting said determined amount of filtering to be applied to said pixel or group of pixels based on said generated motion vector and based on a brightness value.

Abstract
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.
