Abstract
A coder with a motion estimation system, which comprises a same parity field motion estimator, a near field motion estimator, an inter-field interpolated motion estimator, a comparator for selecting the smallest one of prediction errors E1 to E3 output from the respective motion estimators, and a selector for selectively outputting a motion vector from the motion estimator providing the smallest prediction error.
