IMAGE ENCODING DEVICE, IMAGE DECODING DEVICE, IMAGE ENCODING METHOD AND IMAGE DECODING METHOD Russian patent published in 2018 - IPC H04N19/119 H04N19/53 H04N19/61 H04N19/91 

FIELD: data processing.

SUBSTANCE: invention relates to techniques of encoding/decoding images. Image decoding apparatus includes an arithmetic decoding unit for decoding the bitstream to change the occurrence probability as a function of the division of the adjacent block for the block, decoding unit for decoding a bit stream to obtain information indicating a block size and information indicative of a block size threshold value and a prediction unit for determining the estimated vector from the adjacent motion vector and setting it as the motion vector for the first unit of the motion prediction unit and for the second unit of the motion prediction unit, to create a predicted image when the first and second motion prediction mode is an interlace mode.

EFFECT: technical result is higher efficiency of encoding/decoding images.
