Patent ID: 8200032

Claim:
An image processing method, comprising steps of: using a calculation circuit for generating a block matching result by performing a block matching operation according to a plurality of image blocks in a horizontal direction without referring to an image block in a vertical or other directions excluding the horizontal direction; and performing an image processing operation according to the block matching result of the block matching operation; wherein the image processing operation is an image interpolation operation, and, and the step of performing the image processing operation according to the block matching result of the block matching operation comprises: when the block matching result indicates that a plurality of block matching differences calculated according to the plurality of image blocks in the horizontal direction are larger than a predetermined threshold, directly repeating an image block of a previous image, the image block of the previous image being corresponding to a position to be interpolated; and when the block matching result indicates that a minimum block matching difference of the plurality of block matching differences is not larger than the predetermined threshold, performing the image interpolation operation for the position to be interpolated according to a motion vector corresponding to the minimum block matching difference.
