FIELD: data processing.
SUBSTANCE: invention relates to the field of encoding/decoding of three-dimensional images. This inter-prediction method based on the motion information includes: determining a prediction mode for a current block as an inter prediction mode; determining motion information related to the current block; and determining an elementary prediction value for the current block based on the motion information relating to the current block; moreover, the definition of motion information relating to the current block includes: determining whether the central sub prediction unit corresponding to the central position of the current block in the reference block has motion information; determining motion information related to the sub prediction units in the current block; and determining motion information relating to the current block if the central sub prediction unit in the reference block does not have motion information.
EFFECT: improving the efficiency of encoding/decoding of images by eliminating data dependencies in the definition of motion information.
