Description
1.3次元立体映像再生表示システム構成
図1に3次元立体映像再生表示システムの構成を示す。3次元立体映像再生表示システムは、再生装置101、表示装置102及び3D用メガネ103を有する。再生装置101は3次元立体映像をディスクから再生し、表示装置102に出力する。表示装置102は3次元立体映像を表示し、左目用(L)の映像と右目用(R)の映像を交互に表示する。表示装置102は、赤外線などの無線で映像同期信号を3D用メガネ103に送る。3D用メガネ103は、左目用レンズ部及び右目用レンズ部にそれぞれ液晶シャッターを備え、表示装置102からの映像同期信号に基づいて左右の液晶シャッターを交互に開閉させる。具体的には、表示装置102が左目用映像を表示する時には左目用の液晶シャッターが開き、右目用の液晶シャッターが閉じる。表示装置102が右目映像を表示する時には右目用の液晶シャッターが開き、左目用の液晶シャッターが閉じる。このような構成により、液晶シャッターつきメガネをかけたユーザの左目には左目用の映像のみが、右目には右目用の映像のみが届くことになり、これにより、ユーザは3次元立体映像を視認することができる。
図2に再生装置101の構成を示す。再生装置101は、ディスク再生部202、信号処理部203、メモリ204、リモコン受信部205、出力部206およびプログラム格納用メモリ207を有する。リモコン受信部205は、ユーザからの再生開始、停止、飛び出し量補正指示等を受け付ける。ディスク再生部202は、2D映像や3D映像、音声、グラフィックスデータ等が記録されたディスク201を再生する。ビデオ信号処理部203は、ディスク再生部202で再生した映像(ビデオ)、音声(オーディオ)、グラフィックス(文字やメニュー画像など)等のデータをデコードし、メモリ204に一時的に蓄積する。出力部206は、信号処理部203からの信号を所定のフォーマットで出力する。プログラム格納用メモリ207は、機器本体GUIを格納する。機器本体GUIとは、機器本体の操作等を案内するためのグラッフィックデータである。
図3に信号処理部203の構成を示す。信号処理部203は、ストリーム分離部301、オーディオデコーダ302、ビデオデコーダ303、グラフィックスデコーダ304、CPU305及びビデオ信号処理部306を有する。
図4に3次元立体映像の概念図を示す。3D立体映像のデータは、左目用の画像データ401(L0、L1、L2、L3…)と右目用の画像データ402(R0、R1、R2、R3…)とで構成される。L0、L1、L2、L3…、R0、R1、R2、R3…はそれぞれ1つのピクチャに対応するデータを示している。左目用の画像データ401と右目用の画像データ402は、ペアで再生される。左目用の画像データ401(L0、L1、L2、L3…)と右目用の画像データ402(R0、R1、R2、R3…)は、3Dストリーム403としてピクチャ単位で左右交互に伝送される。左目用のピクチャには、このピクチャとこれとペアの右目用のピクチャにおいて最も飛び出し量の大きいオブジェクトのオフセット量に関する情報404が付加されている。このオフセット量をビデオデコーダ303で取得することでピクチャにおける最大飛び出し量をピクチャ単位で検出することが可能である。
オフセット量の調整は、ビデオ信号処理部306で実施される。図5は左目用映像と右目用映像とのオフセット量の調整について説明するための図である。図5(a-1)、(a-2)は、ビデオ信号処理部306に入力されるグラフィックスデータ501を示す。図5(b-1)、(b-2)は、ビデオ信号処理部306に入力される左目用のビデオデータ502L及び右目用のビデオデータ502Rを示す。図5(c-1)、(c-2)は、グラフィックスデータ501と、左目用及び右目用のビデオデータ502L、502Rとに対してビデオ信号処理部306でオフセット調整が行われてこれらが合成され、ビデオ信号処理部306から出力される映像データ502L′、502R′を示す。ここで、オフセット量の調整を行うことは、映像の飛び出し量を調整することを意味する。
映像の飛び出し量を奥方向に(画面に対してユーザとは反対方向に)調整する場合に(左目用及び右目用のビデオデータやグラフィックスデータの飛び出し量が減少するように調整する場合に)、マイナス方向のオフセット量が-50より小さくなると、3Dテレビに表示した際に、左目用ビデオデータ上のオブジェクトやグラフィックスと右目用ビデオデータ上のオブジェクトやグラフィックスとの間隔が、人間の左右の目の間隔を超えてしまい、ユーザが3D映像として正常に認識できなくなるという課題がある。この課題に対処するため、本実施形態では、例えばオブジェクトのオフセット量が-50より小さいときに画像破綻を引き起こす虞があるとした場合、ユーザによりオフセット量がN=-50より小さな値に設定されないように制限をかける。
飛び出し量の調整制御について説明する。図7は、飛び出し量の調整制御に関するフローチャートである。
図8に左目用映像と右目用映像とのオフセット量の調整についての説明図を示す。図8(a-1)、(a-2)は、ビデオ信号処理部306に入力されるグラフィックスデータ801を示す。図8(b-1)、(b-2)は、ビデオ信号処理部306に入力されるGUIデータ804を示す。図8(c-1)、(c-2)は、ビデオ信号処理部306に入力される左目用のビデオデータ802L及び右目用のビデオデータ802Rを示す。図8(d-1)、(d-2)は、グラフィックスデータ801と、左目用及び右目用のビデオデータ802L、802Rと、左目用及び右目用の機器本体GUI804L、804Rとに対してビデオ信号処理部306でオフセット調整が行われてこれらが合成され、ビデオ信号処理部306から出力される映像データ802L′、802R′を示す。
機器本体GUIを合成する場合における飛び出し量の調整制御について説明する。図9は、機器本体GUIの飛び出し量の調整制御に関するフローチャートである。
リモコン受信部205は受付部の一例である。ビデオ信号処理部306は第1調整部、第2調整部及び第3調整部の一例である。CPU305は、判定部、第1判定部、第2判定部及びグラフィックデータ作成部の一例である。
本実施の形態の再生装置101は、立体画像データを、左目用画像データと右目用画像データとにデコードするビデオデコーダ303と、左目用画像データと右目用画像データとのオフセット量を調整するための指示を受け付けるリモコン受信部205(受付部)と、指示に基づくオフセット量となるように、左目用画像データと右目用画像データとのオフセット量を調整するビデオ信号処理部306と、ビデオ信号処理部306で調整されたオフセット量の絶対値が限界値以下か否かを判定するCPU305とを備える。ビデオ信号処理部306は、調整されたオフセット量の絶対値が限界値以下でないとCPU305で判定されたときは、左目用画像データと右目用画像データとのオフセット量の絶対値が限界値以下となるように、左目用画像データと右目用画像データとのオフセット量を調整する。
