Abstract:
An image coding method includes: deriving a candidate for a motion vector predictor from a neighboring motion vector; adding the candidate to a list; selecting a motion vector predictor from the list; coding a current block; and coding a current motion vector. In the deriving, 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.
