1. A movement vector detecting apparatus comprising:

  • a) movement vector detecting means for dividing an input image into a plurality of blocks and for detecting movement vectors in every one of the blocks; and

    b) movement vector calculating means for detecting an effective area including effective blocks on the basis of a distribution of the movement vectors of the plurality of blocks and for calculating a representative movement vector in the effective area by(i) calculating and assigning different weighting values for the movement vectors of the effective blocks according to the position of each effective block within the effective area, and(ii) averaging the weighted movement vectors.
