Abstract:
A decoding method and apparatus are provided. A first candidate having a first motion vector that has been used to decode a first block, a first prediction direction that corresponds to the first motion vector, and a first reference picture index that identifies a first reference picture is derived. A second candidate having a second motion vector that has been used to decode a second block, a second prediction direction that corresponds to the second motion vector, and a second reference picture index that identifies a second reference picture is derived. When a total number of candidates is less than a maximum number, a third candidate is derived by combining the first motion vector and the first reference picture index for the first prediction direction of the first candidate and the second motion vector and the second reference picture index for the second prediction direction of the second candidate.

Claim (Index 1):
An image decoding method for decoding a current block, the image decoding method comprising:\n deriving a first candidate having a first motion vector that has been used to decode a first block, a first prediction direction that corresponds to the first motion vector, and a first reference picture index that identifies a first reference picture corresponding to the first motion vector; deriving a second candidate having a second motion vector that has been used to decode a second block, a second prediction direction that corresponds to the second motion vector, and a second reference picture index that identifies a second reference picture corresponding to the second motion vector;\n determining whether or not a total number of candidates including the first candidate and the second candidate is less than a maximum number; \n generating a third candidate by combining the first motion vector and the first reference picture index for the first prediction direction of the first candidate and the second motion vector and the second reference picture index for the second prediction direction of the second candidate when the total number of the candidates is less than the maximum number; and \n decoding the current block by using a candidate selected from candidates including the first candidate, the second candidate and the third candidate.
