Abstract
A motion estimation apparatus and method is disclosed. The apparatus includes a block error calculator to calculate a specified block error based on a candidate motion vector previously estimated and spatiotemporarily neighboring on a present block; a motion estimation mode decider to decide a motion estimation mode for the present block to be processed based on the calculated block error; and a motion vector estimator to estimate a last motion vector in the decided motion estimation mode.

A motion estimation apparatus comprising:
- a block error calculator to calculate a specified block error based on a candidate motion vector previously estimated and spatiotemporarily neighboring on a present block;
- a motion estimation mode decider to determine a motion estimation mode for the present block to be processed based on the calculated block error;
- and
- a motion vector estimator to estimate a final motion vector in the decided motion estimation mode.
