Disclosed is a motion estimation method using binary block matching in an inter prediction. The motion estimation method using binary block matching comprises the steps of: performing binary transformations of each of pixels constituting the current frame and a reference frame based on a threshold (T) to produce transformed current and reference frames; calculating matching errors of the transformed current frame and the transformed reference frame within a motion search range on the reference frame corresponding to the current block included in the current frame and estimating motion based on the matching error. Therefore, it is possible to reduce complexity by calculating matching errors based on a logical operation and to prevent coding performance from slowing down by excluding pixels included in a specific range from the matching error calculation based on the threshold (T). |
