Abstract

An object of the present invention is to increase efficiency of information compression in coding and decoding. A moving picture encoding apparatusof the present invention has a motion vector predicting part for performing, based on a temporal relation among adjacent reference frame imagesreferred to for detecting motion vectors of adjacent blocks adjacent to a coding target block, a target reference frame imagereferred to for detecting a motion vector of the target block, and a target frame imagebeing the frame image of the coding target, or based on time information thereof, a correction of scaling the motion vectorsof the adjacent blocks on the basis of the target reference frame image; and a determination of an optimum predicted motion vector based on the motion vectors of the adjacent blocks; and thereby predicting the optimum predicted motion vector after the correction.
