ABSTRACT:
A motion compensation processor reads a small regions at the center portion of a forward reference region and a small region at the center portion of a backward reference region preliminarily assigned thereto and determines a coding type. Another motion compensation processor reads a small region at the left side of the forward reference region and a small region at the right side of the backward reference region and determines a coding type. A further motion compensation processor reads a small region at the left side of the forward reference region and a small region at the right side of the backward reference region and determines a coding type. By this parallel processing is enabled to obtain a prediction block having high similarity to a current block more efficiently than the prior art and facilitate realization of a bidirectional predicting system.
