Patent ID: 7684486

Claim:
A method for motion compensated interpolation, the method comprising: (a) storing an input image in frame units; (b) dividing pixels of the stored image into N 1 ×N 2 blocks and M 1 ×M 2 blocks based on the same center axis and sampling pixels in the M 1 ×M 2 blocks, wherein N 1 , N 2 , M 1 and M 2 are positive integers, the M 1 ×M 2 blocks are larger than the N 1 ×N 2 blocks, and adjacent M 1 ×M 2 blocks are overlapped with each other; (c) estimating a motion vector by matching sampled pixels of the M 1 ×M 2 blocks between adjacent frames; and (d) creating a mean pixel value between the adjacent frames using the motion vector and pixel values of matched N 1 ×N 2 blocks between the adjacent frames.
