WIPO Patent Application WO/2012/042719

Kind Code:

A1

Abstract:

When the encoding mode corresponding to a coding block divided by a block division unit (2) is an inter-encoding mode of a direct mode, a motion compensation prediction unit (5) selects a motion vector appropriate for generating a prediction image, from among one or more selectable motion vectors, generates a prediction image by executing a motion compensation prediction process for the coding block using the motion vector, and outputs index information indicating the motion vector to a variable length encoding unit (13); and the variable length encoding unit (13) performs variable length encoding of the index information.
