摘要 An object of the present invention is to increase efficiency of information compression in coding and decoding. A moving picture encoding apparatus 10 of the present invention has a motion vector predicting part for performing, based on a temporal relation among adjacent reference frame images 703a, 703b, 703c referred to for detecting motion vectors of adjacent blocks adjacent to a coding target block, a target reference frame image 702 referred to for detecting a motion vector of the target block, and a target frame image 701 being the frame image of the coding target, or based on time information thereof, a correction of scaling the motion vectors 751a, 751b, 751c of the adjacent blocks on the basis of the target reference frame image 702; 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.
