Abstract
A moving picture encoding device includes a motion vector detection section configured to detect a motion vector of a predetermined area to be encoded in a frame picture, a prediction section configured to predict 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 section configured to determine whether or not the motion vector detected by the motion vector detection section is a predetermined motion vector set in accordance with the motion vector predicted by the prediction section, and a switching section configured to switch 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 section is the predetermined motion vector.
