Abstract: The invention provides an apparatus and a method for motion estimation. The motion estimation apparatus includes a candidate set generation circuit and a motion vector (MV) determination circuit. The candidate set generation circuit selects to add motion vectors of adjacent blocks into a motion vector candidate set of a current block of a current frame. The current block and one of the adjacent blocks belong to the same row (or the same column), and the one of the adjacent blocks is a block of the current frame or a block of a previous frame. The motion vector determination circuit is coupled to the candidate set generation circuit to receive the motion vector candidate set. The motion vector determination circuit determines the motion vector of the current block of the current frame according to the motion vector candidate set.
