Patent ID: 8265138

Claim:
An image processing method adapted to be used in a liquid crystal display, comprising the steps of: (A) determining which blocks in a decoded current frame are noisy blocks; (B) finding, in a processed reference frame, a most similar reference block for each noisy block, and generating a block velocity for each noisy block; and (C) processing pixels that are in the noisy blocks having block velocities smaller than the liquid crystal response rate of the liquid crystal display, and that are not covered by after-images; wherein the liquid crystal response rate is equal to the pixel pitch of the liquid crystal display divided by a liquid crystal response time of the liquid crystal display, the block velocity being computed as follows: V b = x 2 + y 2 · D p Δ t where V b is the block velocity, (x,y) is a motion vector of pointing towards the reference block from the noisy block, D p is the pixel pitch of the liquid crystal display, and Δt is the time difference between the display of the current frame and the reference frame.
