Claim 6:
7. A method for determining similarity of adjacent rows in a picture, comprising:
obtaining feature values of corresponding sub-pixels of each row of picture data in a frame of picture data, a number of total rows in the frame of picture data being N;
subtracting feature values of corresponding sub-pixels of row n and row n−1 of picture data in the frame of picture data, and summing absolute values of multiple differences obtained from the subtracting;
determining similarity of the row n and row n−1 of picture data in the frame of picture data according to a summed value obtained from the summing; and
judging whether n equates to N, in determining that n equates to N, ending processing, in determining that n is not equal to N, increasing n by 1 that is n=n+1 and returning to “subtracting feature values of corresponding sub-pixels of row n and row n−1 of picture data in the frame of picture data, and summing absolute values of multiple differences obtained from the subtracting”;
wherein an initial value of n is 2.
