Abstract
A video coding device performs video coding using a block based affine transform motion compensated prediction technique that includes a process of calculating a motion vector of each subblock using motion vectors of control points in a block. The video coding device includes block based affine transform motion compensated prediction control means for controlling at least one of a block size, a prediction direction, and a motion vector precision of the subblock in the block subjected to the block based affine transform motion compensated prediction, using a coding parameter supplied from outside.
