Abstract

Para permitir mayor seguridad para vender películas de HDR (o por los menos experiencias de HDR) incluso cuando algunos de los datos de la película son pirateados, se dispone un aparato de transformación de imágenes (201) para derivar, por ejemplo, una imagen de alto rango dinámico (HDR_PRED) a partir de una imagen de bajo rango dinámico (LDR_CONT) o imagen de cualquier rango dinámico (por ejemplo, una imagen de excitación de pantalla) de una imagen de entrada de cualquier rango dinámico, en donde la derivación comprende la asignación de tonos de lumas de píxeles en la imagen de bajo rango dinámico a lumas de píxeles de la imagen de alto rango dinámico aplicando por lo menos un algoritmo de asignación predefinido (gam), el aparato de transformación de imágenes comprende: una entrada (204) a un sistema de suministro de datos (205) que comprende la imagen de bajo rango dinámico; una entrada de datos segura (206) al por lo menos un dato del algoritmo de asignación predefinido (gam); y una unidad de control (202) dispuesta para administrar el acceso a los datos del algoritmo de asignación predefinido bajo el control de un propietario de contenido artístico en la imagen de bajo rango dinámico, lo cual permite mejor control de la regularidad autorizada del contenido cuando va a renderizarse, lo cual es posible gracias a nuestra estrategia especial de codificación de imágenes de HDR.
