IMAGE PREDICTION CODING DEVICE, AN IMAGE PREDICTION CODING METHOD, AN IMAGE PREDICTION CODING PROGRAM, AN IMAGE PREDICTION DECODING DEVICE, AN IMAGE PREDICTION DECODING METHOD, AN IMAGE PREDICTION DECODING PROGRAM Russian patent published in 2019 - IPC H04N19/61 H04N19/119 H04N19/46 H04N19/44 

FIELD: computer engineering.

SUBSTANCE: invention relates to the computer engineering. Image prediction decoder comprises a memory which stores a program executed by a decoder to extract encoded identification information from the compressed data, which determines an area which is used to generate a prediction signal of the target area and encoded residual signal data; determining a neighboring block of a plurality of adjacent blocks which are adjacent to the target area based on the identification information; generate a prediction signal of the target area from the recovered signal, wherein when the neighboring block is predicted by intra-picture prediction and the target area is predicted by inter-map prediction, and vice versa, prediction information associated with the neighboring block is not used; recover residual target region reproducing signal; create and store target area reproducing signal as recovered signal in memory.

EFFECT: reduced prediction error target unit.
