A method for processing a motion image comprises of receiving a plurality of frames of a motion image, and dividing each frame into a plurality of macro blocks. Then, one of the macro blocks defines a comparing block. The pixels in the comparing block of a current frame are processed using a SAD operation with the pixels in a macro block in a searching of the pre-frame to obtain a SAD threshold value. In addition, the present invention lets the pixels in the comparing block process a SAD operation with the macro block that has not yet been processed by a SAD operation, thus obtaining an accumulation value of a plurality of the SAD values. When the accumulation value is greater than or equal to the SAD threshold value, the SAD operation is interrupted.
