FIELD: encoding and decoding of three-dimensional images.
SUBSTANCE: result is achieved by determining motion information relating to the current block and determining an elementary prediction value for the current block based on the motion information relating to the current block. Step of determining motion information relating to the current block includes determining whether the central sub-block in the reference block has motion information, wherein the central sub-unit corresponds to the central position of the current unit; determining motion information relating to subunits in the current block if the central subunit in the reference block has motion information; and determining motion information relating to the current block if the central sub-block in the reference block has no motion information. Motion information includes at least one of a motion vector and a reference index.
EFFECT: high efficiency of encoding and decoding images by eliminating dependence on data when determining motion information.
