摘要：
An image coding method bitstream includes: determining a maximum number of a merging candidate which is a combination of a prediction direction, a motion vector, and a reference picture index for use in coding of a current block; deriving a first merging candidate; determining whether or not a total number of the first merging candidate is smaller than the maximum number; deriving a second merging candidate when it is determined that the total number of the first merging candidate is smaller than the maximum number; selecting a merging candidate for use in the coding of the current block from the first merging candidate and the second merging candidate; and coding, using the maximum number, an index for identifying the selected merging candidate, and attaching the coded index to the bitstream.
