IMAGE ENCODING APPARATUS, IMAGE DECODING APPARATUS, IMAGE ENCODING METHOD AND IMAGE DECODING METHOD Russian patent published in 2014 - IPC H04N19/196 G06T7/20 

FIELD: information technology.

SUBSTANCE: image decoding apparatus receives a predictive-coded bit stream which is generated by dividing each frame of a moving image signal into reference units of a given size. The apparatus decodes the bit stream to obtain a moving image signal. The apparatus includes a decoding unit for decoding the bit stream to obtain information which indicates a given size. The apparatus also operates in motion prediction mode and determines the motion vector for each of the reference units, or for each of the single motion prediction units defined as units obtained by hierarchical division of the reference units. The motion prediction mode determines the motion prediction procedure for single motion prediction units.

EFFECT: high efficiency of decoding information.
