A motion estimation method applied to a video signal having a first frame and a second frame is provided. The motion estimation method includes: capturing a matching window from the first frame; capturing a searching area from the second frame, the searching area including a plurality of searching blocks each having a size equal to that of the matching window; selecting one of the searching blocks; calculating a difference between pixel data of the selected searching blocks and pixel data of the matching window, so as to obtain N total differences corresponding to N searching blocks; and determining a motion vector corresponding to the matching window according to the N total differences. |
