摘要： Disclosed is video encoding technology, and more particularly a method for searching for a motion vector in a procedure of estimating a motion in video frames. The motion vector search method includes the steps of: individually calculating error energies of a center point and vertices of a search pattern in a search window used in a previous frame with respect to a center of the search window established in the current frame, thereby designating a motion vector candidate point; either determining the motion vector candidate point as a moving point of a motion vector, or calculating error energies of a pair of neighboring points and re-establishing a motion vector candidate point; and either determining the re-established motion vector candidate point as a moving point of a motion vector, or re-establishing a search pattern, re-checking the error energies of the center point, the vertices and the neighboring points, and determining a moving point of a motion vector.
