Abstract
Un procesador de gestión de pantalla recibe una imagen de entrada con gama dinámica mejorada para ser visualizada en una pantalla blanco que tiene una gama dinámica diferente al de una pantalla de referencia. La imagen de entrada se transforma primero en un espacio de color cuantizado perceptualmente (PQ), preferiblemente el espacio de color IPT-PQ. Una función de asignación de volumen de color, que incluye una función de asignación de tono adaptable y una función de asignación de gama adaptativa, genera una imagen asignada. Se aplica una etapa de conservación de detalle al componente de intensidad de la imagen asignada para generar una imagen asignada final con una imagen de intensidad de asignación de tono filtrada. La imagen asignada final se traduce entonces de nuevo al espacio de color preferido de la pantalla. Se proporcionan ejemplos de las funciones de asignación de tono adaptable y de asignación de gama.
