Patent ID: 7623577

Claim:
A frame rate modulation method for filtering discontinuities at a boundary between adjacent blocks of a frame of a video image performed using logic on an integrated circuit chip, comprising: a) identifying adjacent pixels located on each side of a boundary between adjacent blocks of a first frame of a video image, each of the adjacent pixels being associated with a pixel value, using the logic on the integrated circuit chip; b) determining a difference between the adjacent blocks based on the pixel values of the adjacent pixels, using the logic on the integrated circuit chip; c) if a difference between adjacent image blocks of the first frame is less than a quantization parameter, then the method includes defining a second frame having the pixel value for each of the adjacent pixels swapped; and averaging the pixel value associated with each adjacent pixel by alternately displaying the pixel value associated with each adjacent pixel to present an image having a smoothed block boundary, using the logic on the integrated circuit chip.
