IMAGE ENCODING DEVICE, IMAGE DECODING DEVICE, IMAGE ENCODING METHOD AND IMAGE DECODING METHOD Russian patent published in 2015 - IPC H04N19/53 G06T7/20 

FIELD: information technology.

SUBSTANCE: image decoding device receives the feedforward encoded bit stream, which is generated by dividing each signal frame of the moving image on the support blocks of a given size. The device decodes the bit stream for receiving the moving image signal. The device comprises a module of decoding for decoding the bit stream for receiving the information indicating the given size, and the information indicating the threshold block size. The device also operates in the mode of the motion prediction and determines the motion vector for each of the support blocks, or for each of the single blocks of the motion prediction, identified as blocks received by hierarchical division of the support blocks. The motion prediction mode defines the procedure of the motion prediction for the single blocks of the motion prediction.

EFFECT: increased efficiency of decoding the information.
