摘要： The present invention relates to a motion error detector comprising a motion estimator for dividing a current frame into a plurality of blocks having a predetermined size, and estimating a motion vector of a current block by comparing the current block among the plurality of blocks with a predetermined searching region set in a previous frame. A global motion estimator calculates a global motion vector on the basis of motion vectors of neighboring blocks of the current block; and an error detector compares the motion vector of the current block and a corresponding motion estimation error for estimating motion with the global motion vector and a corresponding global motion estimation error, respectively, and determines whether the motion vector of the current block is erroneous. Thus, a motion error detector, a motion error compensator including the same, and a method for detecting and compensating a motion error using the motion error compensator is provided, in which a motion error of a current block is detected on the basis of a global motion, and the motion error is decreased by changing a compensation mode according to the number of detected errors.
