Abstract:
An image decoding method and apparatus derive: a first candidate having a first motion vector; a second candidate having a second motion vector and a first reference picture index value that identifies a first reference picture corresponding to the second motion vector; and a third candidate having a third motion vector and a second reference picture index value that identifies a second reference picture corresponding to the third motion vector. The second and third motion vectors are first and second zero vectors. The first and second reference picture index values are different. A coded index attached to the bitstream is decoded using a maximum number of candidates including the first, second, and third candidates. The coded index indicates one candidate of the candidates. The candidate is selected based on the coded index and is used for decoding a current block.

Claim (Index 1):
An image decoding method for decoding a current block included in a bitstream, the image decoding method comprising:\n deriving a first candidate having a first motion vector that has been used to decode a first block; deriving a second candidate having a second motion vector and a first reference picture index value that identifies a first reference picture corresponding to the second motion vector, the second motion vector being a first zero vector; deriving a third candidate having a third motion vector and a second reference picture index value that identifies a second reference picture corresponding to the third motion vector, the third motion vector being a second zero vector, the first reference picture index value being different from the second reference picture index value; decoding a coded index attached to the bitstream using a maximum number of a plurality of candidates including the first candidate, the second candidate, and the third candidate, the coded index indicating one candidate of the plurality of candidates; and selecting the candidate, based on the coded index, the candidate being used for decoding the current block, the selected candidate including a motion vector and a reference picture index value.
