An image processing method comprises obtaining a current frame and a previous frame, performing a bilateral motion estimation to the current frame and the previous frame for acquiring a motion vector, and performing a motion compensated interpolation to the current frame, the previous frame and the motion vector for acquiring an interpolated frame. The bilateral motion estimation uses sum of bilateral absolute difference algorithm to generate at least one sum of bilateral absolute difference, and then an adaptive parameter is added to each of the sum of bilateral absolute difference to generate at least one adaptive sum of bilateral absolute difference. A group of matching blocks having a minimum adaptive sum of bilateral absolute difference is then determined to be the group of best matching blocks. The motion vector is obtained according to the relative locations of the best matching blocks.
