Abstract
An object of the present invention is to express a predicted picture signal with light overheads, and to provide motion compensation of different pixel accuracy. A moving picture encoding deviceaccording to the present invention includes a motion vector detection meansfor detecting a motion vector of a predetermined area to be encoded in a frame picture, a prediction meansfor predicting the motion vector of the predetermined area to be encoded by using an encoded motion vector of a predetermined area in the frame picture, a determination meansfor determining whether or not the motion vector detected by the motion vector detection meansis a predetermined motion vector set in accordance with the motion vector predicted by the prediction means, and a switching meansfor switching a method of calculating a motion compensation value of the predetermined area to be encoded depending on whether or not the motion vector detected by the motion vector detection meansis the predetermined motion vector.
