Abstract
【解決手段】コーディングしようとするピクチャの現ブロックに関して、現ブロックの左位置、上位置、右上位置のいずれかに隣接するブロックであって、現ブロック以外の他のブロックの第1及び第2動きベクトルを求める段階と、現ブロックの第1動きベクトルが、他のブロックの第1動きベクトルと同一の方向を有し、かつ、現ブロックの第2動きベクトルが、他のブロックの第2動きベクトルと同一の方向を有するように、他のブロックの第1及び第2動きベクトルを用いて、現ブロックの第1及び第2動きベクトルを決定する段階であって、他のブロックの第1動きベクトル及び他のブロックの第2動きベクトルに対してメディアン演算を行なう段階を含む段階と、を有することを特徴とする。
【選択図】図1
Description
PMV=median{MVA,MVB,MVC}
以下、添付図面を参照しつつ本発明による実施例を詳細に説明する。
まず、コーディングしようとするブロックの予測動きベクトル‘PMV’を求めるには、周辺ブロックの動きベクトルに対する方向情報を把握しなければならない。そして、各ブロックの動きベクトルに対する方向情報に基づいて、メディアン演算に該当周辺ブロックの動きベクトルを含ませるか否か決定する。
コーディングしようとするブロックの周辺ブロックが双予測モードまたはダイレクトモードであれば二つの動きベクトルを有することになり、このうちコーディングしようとするブロックに対して演算しようとする予測動きベクトル‘PMV’と同一の方向を有する動きベクトルがメディアン演算に使用されるべきである。本発明で提示する効率的な予測動きベクトル‘PMV’演算方法を、次に詳細に説明する。このとき、図1に示すと同様に、コーディングしようとするブロックをE、周辺ブロックをA、B、C、Dとし、周辺ブロックの二つの動きベクトルをそれぞれMV1、MV2と設定する。
コーディングしようとするブロック(例えば、E)に対して、求めようとする予測動きベクトル‘PMV’と(各周辺ブロックA、B、CまたはA、B、Dの動きベクトルの中で)同一の方向の動きベクトルを選択した後、メディアン演算を通じて予測動きベクトル‘PMV’を求める。
まず、コーディングしようとするブロックEが参照するレファレンスピクチャを、周辺ブロックの二つの動きベクトルが参照しているか検査する。
‘MV1’と‘MV2’とを有する周辺ブロックの動きベクトルを‘0’と設定した後、レファレンスピクチャを、ブロックEが参照するレファレンスピクチャと異なると設定し、メディアン演算に含ませてコーディングしようとするブロックの予測動きベクトル‘PMV’を求める。
