Abstract

Se proporciona un método de presentación visual para presentar visualmente, en un dispositivo de presentación visual, video de datos de video donde la luminancia de video está definida por una primera EOTF (función de transferencia electro-óptica) que corresponde a HDR (al to intervalo dinámico). El método incluye: adquirir los datos de video; llevar a cabo primera conversión en donde la luminancia del video se convierte en una luminancia correspondiente a un intervalo dinámico de una tercera EOTF, donde, con respecto a una segunda EOTF que es parte de la primera EOTF y es la parte de un intervalo de luminancia donde la luminancia pico indicada por la información de luminancia pico incluida en los datos de video adquiridos es la luminancia máxima, el intervalo dinámico de luminancia de la segunda EOTF se reduce con la luminancia máxima de la segunda EOTF que coincide con la luminancia que puede presentarse visualmente del dispositivo de presentación visual, mientras se mantiene la relación relativa de luminancia de la segunda EOTF; y presentar visualmente el video en el dispositivo de presentación visual usando el resultado de la primera conversión.
