Abstract: An image coding method includes: deriving a candidate for a motion vector predictor from a co-located motion vector (S1301); adding the candidate to a list (S1302); selecting the motion vector predictor from the list (S1303); and coding a current block and coding a current motion vector (S1304), wherein the deriving (S1301) includes: deriving the candidate by a first derivation scheme in the case of determining that each of a current reference picture and a co-located reference picture is a long-term reference picture; and deriving the candidate by a second derivation scheme in the case of determining that each of the current reference picture and the co-located reference picture is a short-term reference picture.

Abstract: An image coding method according to an aspect of the present invention includes: writing, into a sequence parameter set, buffer description defining information for defining a plurality of buffer descriptions (S102); writing, into the sequence parameter set, reference list description defining information for defining a plurality of reference list descriptions corresponding to the buffer descriptions (S103); and writing, into a first header of each processing unit which is included in a coded bitstream, buffer description selecting information for specifying a selected buffer description (S105).

Abstract: An image coding method includes: writing, into a coded bitstream, buffer description defining information for defining a buffer description (S101); constructing a default reference list (S102); reordering pictures included in the default reference list (S103); writing, into the coded bitstream, reference list reordering information for indicating details of the reordering (S104); and coding an image using the buffer description and a reference list resulting from the reordering (S105), and in the reference list reordering information, among the pictures, a picture to be reordered is specified using an index which is used in other processing in the image coding method.
