Abstract
The invention provides a motion compensation predicted picture production apparatus which can produce a motion compensated predictive picture which includes minimized prediction errors. The motion compensated predictive picture production apparatus includes a pair of warping motion compensation circuits which produce, for different first grid point arrangement and second grid point arrangement, motion compensated predictive pictures by warping motion compensation. An averaging circuit averages the two motion compensated predictive pictures outputted from the warping motion compensation circuits to obtain a motion compensated predictive picture. The motion compensated predictive picture is outputted from the averaging circuit as an output of the motion compensated predictive picture production apparatus.
