Abstract

L'invention porte sur un remodelage direct en temps réel, consistant à : sélectionner une fenêtre glissante statistique qui indexe avec la trame courante, ayant également, une trame de rétrospective et une trame d'anticipation, déterminer si elles font partie de la scène courante, déterminer un paramètre de bruit, une fonction de transfert de luminance et une fonction de remodelage direct de luminance sur la base de la fonction de transfert de luminance et du paramètre de bruit dans la scène courante, sélectionner une fenêtre glissante de tendance centrale de la trame courante et de la trame de rétrospective dans la scène courante, et déterminer une fonction de remodelage direct de luminance de tendance centrale. Le remodelage de chrominance comprend l'analyse de statistiques pour les pondérations de plage dynamique étendue (EDR) et les limites supérieures EDR, la mise en correspondance de ces pondérations de plage dynamique standard (SDR) et des limites supérieures SDR sur la base de la fonction de remodelage direct de luminance de tendance centrale, la détermination d'un polynôme dépendant du contenu de chrominance et d'un polynôme de remodelage direct de chrominance à tendance centrale et la génération des coefficients MMR de chrominance.
