Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An encoding and decoding apparatus, the encoding and decoding apparatus comprising: an image encoding apparatus which encodes each of blocks of pictures; and an image decoding apparatus which decodes each of blocks of pictures, wherein the image coding apparatus includes: a deriving unit configured to derive a candidate for a motion vector predictor to be used in encoding of a motion vector for a current block to be encoded, from a first motion ve…
