Abstract:
A moving picture encoding apparatus has a motion vector predicting part for performing, based on a temporal relation among adjacent reference frame images referred to for detecting motion vectors of adjacent blocks adjacent to a coding target block, a target reference frame image referred to for detecting a motion vector of the target block, and a target frame image being the frame image of the coding target, or based on time information thereof, a correction of scaling the motion vectors of 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.

Claim (Index 5):
A moving picture decoding method of dividing a frame image as a decoding target in a moving picture signal consisting of a temporal series of frame image signals, into a plurality of target regions, and utilizing difference information between a predicted motion vector and motion vectors for the respective target regions detected with reference to a plurality of frame images different from the frame image as the decoding target, to perform decoding based on motion compensation, the moving picture decoding method executed by motion vector predicting means, comprising:\n a step of determining an optimum predicted motion vector based on a motion vector of an adjacent region adjacent to the target region; a step of correcting a scale of the optimum predicted motion vector based on a temporal relation among an adjacent reference frame image referred to for detecting a motion vector of the adjacent region determined as the optimum predicted motion vector, a target reference frame image referred to for detecting a motion vector of the target region, and a target frame image being the frame image as the decoding target, or based on time information thereof, on the basis of the target reference frame image; and a step of performing a calculation using the corrected optimum predicted motion vector, on a value calculated based on a motion vector between the target frame image and the target reference frame image, and the predicted motion vector, to restore a motion vector.
