MOVING IMAGE ENCODING DEVICE, MOVING IMAGE DECODING DEVICE, MOVING IMAGE ENCODING METHOD AND MOVING IMAGE DECODING METHOD Russian patent published in 2015 - IPC H04N19/61 H04N19/51 

FIELD: physics, computer engineering.

SUBSTANCE: group of inventions relates to computer engineering. An image decoding device comprises a unit for performing a variable word length decoding process on encoded data, multiplexed into a bit stream, to obtain compressed data, an encoding mode and index information, each associated with an encoding unit; a unit for performing a motion compensation prediction process on the encoding unit, based on the encoding mode, to generate a prediction image using a motion vector selected from one or more selected candidate motion vectors, wherein said unit selects a spatial motion vector which is obtained from a decoded unit located near the encoding unit, or a temporary motion vector which is obtained from a decoded picture, on which the encoding unit can make a link according to the index information; a unit for generating data of a decoded image through summation of a difference image obtained by decoding compressed data and a prediction image.

EFFECT: reducing the amount of code.
