An image coding method includes: (i) determining, for each of one or more associated blocks, whether to add a motion vector of the associated block to a list, and (ii) adding the motion vector of the associated block to the list when determining that the motion vector of the associated block is to be added to the list; selecting, from the list, a motion vector which is to be merged to a current block; and (i) merging the selected motion vector to the current block, and (ii) coding the current block using the merged motion vector as a motion vector of the current block, and in the determining, it is determined that the motion vector of the associated block is not to be added to the list when an associated picture and an associated reference picture match temporally or when a current picture and a current reference picture match temporally.
