Title:
IMAGE ENCODING METHOD, IMAGE DECODING METHOD, IMAGE ENCODING DEVICE, AND IMAGE DECODING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/061551
Kind Code:
A1
Abstract:
An image encoding method comprises: a deriving step (S1201) of deriving a candidate of a predicted motion vector from an adjacent motion vector; an adding step (S1202) of adding the candidate to a list; a selecting step (S1203) of selecting the predicted motion vector from the list; and an encoding step (S1204) of encoding a current block and encoding a current motion vector. In the deriving step (S1201), when a current reference picture and an adjacent reference picture are each determined to be a long-term reference picture, the candidate is derived by a first deriving method. When the current reference picture and the adjacent reference picture are each determined to be a short-term reference picture, the candidate is derived by a second deriving method.
