    Abstract: An image coding method includes: determining a maximum number of merging candidates (S601); deriving first merging candidates based on blocks spatially or temporally neighboring a current block (S602); determining whether or not a total number of the first merging candidates is smaller than the maximum number (S604); deriving, by making a combination out of the derived first merging candidates, a second merging candidate for bi-directional prediction when it is determined that the total number of the first merging candidates is smaller than the maximum number (S605); selecting a merging candidate to be used for the coding of the current block from the first merging candidates and the second merging candidate (S606); and coding, using the determined maximum number, an index for identifying the selected merging candidate, and attaching the coded index to the bitstream (S607).

    Abstract: An image decoding method of decoding, on a per-block basis, a coded image included in a bitstream, includes: performing arithmetic decoding on a current block to be decoded (S101); determining whether or not the current block is at the end of a slice(S103); determining, when it is determined that the current block is not at the end of the slice, whether or not the current block is at the end of a sub-stream which is a structural unit of the image that is different from the slice (S105); and performing arithmetic decoding on a sub-last bit and performing arithmetic decoding termination, when it is determined that the current block is at the end of the sub-stream (S106).

    Abstract: An image coding method includes: deriving a candidate for a motion vector predictor from a neighboring motion vector (S1201); adding the candidate to a list (S1202); selecting a motion vector predictor from the list; coding a current block (S1203); and coding a current motion vector (S1204). In the deriving (S1201), the candidate is derived according to a first derivation scheme when each of a current reference picture and a neighboring reference picture is determined to be a long-term reference picture, and the candidate is derived according to a second derivation scheme when each of a current reference picture and a neighboring reference picture is determined to be a short-term reference picture.
