Abstract
A motion vector difference detection stage detects a difference D in motion vector between a current frame and a succeeding frame and a difference D in motion vector between a preceding frame and current frame. A latched circuit outputs the motion vector S of the inputted current frame as a motion vector S in the case where both of the absolute values of the differences D and D does not exceed a preset value L , and outputs the motion vector S of the frame preceding the corresponding frame as a motion vector S in the case where at least one of the absolute values of the differences D and D exceeds the preset value L . The latched circuit outputs a motion vector of 0 as a motion vector S in the case where both of the absolute values of the differences D and D exceed the preset value L and also the absolute value of the sum of the differences D and D exceeds the preset value L . When a change in motion vector is small, the motion vector of the corresponding frame carries out dynamic image correction. When a change in motion vector is large, the small motion vector of the preceding frame or the motion vector of 0 carries out dynamic image correction.
