Abstract:
(EN) This technology pertains to a playback device, playback method, and recording medium whereby graphics having a high luminance dynamic range can be displayed at an appropriate brightness. A graphics stream is recorded on an optical disc, said graphics stream containing the following: tone_mapping_info containing HDR information indicating the luminance characteristics of HDR graphics having a second luminance range that differs from and is higher than a first luminance range; tone_mapping_info consisting of tone-mapping definition information used when performing a luminance conversion from the HDR graphics to STD graphics having the aforementioned first luminance range; and data representing the HDR graphics. This technology can be applied to a recording medium on which graphics are recorded.
(FR) La technologie de l’invention concerne un dispositif de lecture, un procédé de lecture et un support d’enregistrement au moyen desquels des graphiques ayant une plage dynamique de luminances élevée peuvent être affichés au niveau de luminosité approprié. Un flux de graphiques est enregistré sur un disque optique, ledit flux de graphiques contenant ce qui suit : des informations tone_mapping_info contenant des informations HDR indiquant les caractéristiques de luminance des graphiques HDR ayant une deuxième plage de luminances qui diffère d’une première plage de luminances et est supérieure à cette première plage ; les informations tone_mapping_info consistant en informations de définition de mise en correspondance de tonalités utilisées lors de l’exécution d’une conversion de luminance entre les graphiques HDR et les graphiques STD ayant la première plage de luminances mentionnée ci-dessus ; et les données représentant les graphiques HDR. Cette technologie peut être appliquée à un support d’enregistrement sur lequel les graphiques sont enregistrés.
(JA)  本技術は、輝度のダイナミックレンジが広いグラフィックスを適切な明るさで表示させることができるようにする再生装置、再生方法、および記録媒体に関する。 光ディスクには、第1の輝度範囲と異なるより広い第2の輝度範囲のグラフィックスであるHDRグラフィックスの輝度の特性を示すHDR情報を含むtone_mapping_info、HDRグラフィックスから第1の輝度範囲のグラフィックスであるSTDグラフィックスへの輝度変換を行うときに用いられるtone mapping定義情報であるtone_mapping_info、および、HDRグラフィックスのデータを含むグラフィックスストリームが記録される。本技術は、グラフィックスを記録する記録媒体に適用することができる。
