Abstract

Official abstract text for this publication.

A moving picture coding apparatus includes: a motion vector predictor candidate calculation unit which calculates motion vector predictor candidates and the number of motion vector predictor candidates; an inter prediction control unit which selects an optimum motion vector predictor candidate; and a variable length coding unit which sets the motion vector predictor candidate list size to the number of motion vector predictor candidates, and assigns a bit string according to the motion vector predictor candidate list size to a motion vector predictor index used for coding a motion vector, thereby performing variable length coding.

First claim

Opening claim text (preview).

The invention claimed is: 1. A moving picture decoding method for decoding a current block, comprising: deriving a first candidate having a first motion vector predictor derived from a first motion vector that has been used to decode a first block; determining whether a total number of one or more candidates having the first candidate is less than a maximum candidate number; deriving a second candidate having a second motion vector predictor when the total number of the one or…
