Abstract:
(EN) The present invention achieves image processing that allows appropriate luminance conversion to be performed on video data even if there is an abnormality in metadata. The present invention is provided with: a determination unit (17) that determines whether or not there is an abnormality in metadata (12C) which is added to video data (12B) and which is used in luminance conversion of the video data (12B); and a luminance conversion unit (15) that, in the case when the determination unit (17) has determined that an abnormality is present, performs luminance conversion on the video data (12B) using alternative data (12D) which is different from the metadata (12C).
(FR) La présente invention obtient un traitement d'image qui permet d'effectuer une conversion de luminance appropriée sur des données vidéo même s'il y a une anomalie dans des métadonnées. La présente invention comprend : une unité de détermination (17) qui détermine s'il existe, ou non, une anomalie dans des métadonnées (12C) qui sont ajoutées à des données vidéo (12B) et qui sont utilisées dans la conversion de luminance des données vidéo (12B) ; une unité de conversion de luminance (15) qui, dans le cas où l'unité de détermination (17) a déterminé qu'une anomalie est présente, effectue une conversion de luminance sur les données vidéo (12B) à l'aide de données alternatives (12D) qui sont différentes des métadonnées (12C).
(JA) メタデータに異常がある場合にも、映像データに適切な輝度変換を施すことが可能な画像処理を実現する。映像データ(12B)に付加された、映像データ(12B)の輝度変換に用いられるメタデータ(12C)の異常の有無を判定する判定部(17)と、判定部(17)が異常有と判定した場合に、メタデータ(12C)とは異なる代替データ(12D)を用いて映像データ(12B)に輝度変換を施す輝度変換部(15)とを備える。
