摘要

FIELD: data processing.;SUBSTANCE: invention relates to the video encoding/decoding. Predictive video encoding device comprises: into areas dividing means, which divides the input image into plurality of areas; predicted signal generation means, which determines the motion vector for the signal extraction, having a high correlation with the target region; motion information storage means, which stores the motion vector; residual signal generation means, which generates the residual signal between the target area predicted signal and thee target area pixel signal; the residual signal compression means, which compresses the residual signal; residual signal reconstruction means, which generates the reproducible residual signal by the residual signal compressed data reconstruction; and the encoding means, which selects and encodes the motion vector predictor, similar to the target area motion vector; and the images storage means, which adds the predicted signal to the reproduced residual signal for the target area pixel signal reconstruction, and which stores the reconstructed pixel signal as the previously mentioned reproduced image.;EFFECT: increase in the noise reduction performance in the predicted signal with the smaller amount of encoding bits.;8 cl, 20 dwg
