Title:
符号化方法および符号化装置
Document Type and Number:
Japanese Patent JP5347081
Kind Code:
B1
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.
