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 indica una correlación de luminancia de HDR (alto intervalo dinámico) y valores de código. El método incluye: adquirir los datos de video; llevar a cabo, con respecto a cada uno de una pluralidad de pixeles que componen el video incluido en los datos de video adquiridos, primera determinación de determinar si la luminancia de ese pixel excede o no una primera luminancia predeterminada; llevar a cabo, con respecto a cada uno de la pluralidad de pixeles, asignación de tonos dual donde la luminancia de ese pixel se reduce por un formato diferente en caso de que se encuentre que la luminancia del pixel supera la primera luminancia predeterminada como resultado de la primera determinación, y en caso de que se encuentre que la luminancia del pixel es igual o inferior a la primera luminancia predeterminada; y presentar visualmente el video en el dispositivo de presentación visual usando los resultados de la asignación de tonos dual.
