FIELD: computer engineering.
SUBSTANCE: invention relates to the computer engineering. Image prediction decoding method for a prediction decoding device comprises extracting, from compressed data, encoded identification information data which determines an area, which must be used when generating a prediction signal of the target area and encoded residual signal data; determining neighbor area from plurality of neighboring area candidates adjacent to target area, based on identification information decoded from encoded identification information data, and generating a prediction signal of the target area from the recovered signal by using the mode information determined by the inter-map prediction, the reference picture number and the motion vector; recovering the residual reproduction signal of the target area from the encoded residual signal data; generating a target area reproduction signal based on a prediction signal of the target area and a residual reproduction signal; and storing the reproduction signal of the target area as the reconstructed signal.
EFFECT: in reducing the prediction error of the target block.
