ABSTRACT:
A motion vector detection apparatus for detecting a motion vector by performing block matching between a target block including a plurality of pixels in a current image, and a reference block including a plurality of pixels in a predetermined reference area in a past image that is previous to the current image, the apparatus including a first address generator for generating addresses of data in the target block and addresses of data in the reference area; a first storage unit for holding data of the reference area designated by the first address generator; a second storage unit for holding data of the target block designated by the first address generator; a second address generator for generating addresses of data to be outputted from the first storage unit and the second storage unit; and a motion vector detector for detecting a motion vector by using the data outputted from the first storage unit and the data outputted from the second storage unit; wherein the motion vector detector subtracts the absolute values of differences in pixel data between the reference block and the target block, one by one, from a threshold value, and when the result of subtraction becomes negative, the motion vector detector stops calculation of the sum of absolute differences in the corresponding position.
