Abstract

La invención se relaciona al escalamiento de componentes de diferencia de color previo a la codificación a fin de extender el rango dinámico. En una modalidad los componentes de diferencia de color son codificados previo a la cuantificación. En otra modalidad los componentes de diferencia de color son codificados después de la cuantificación. Un decodificador se configura para procesar datos representativos del factor de amplificación para un proceso de decodificación.
