Abstract

Un pre-procesamiento de pixeles comprende submuestrear un color lineal en un primer espacio de color para obtener un color lineal submuestreado en el primer espacio de color. Se aplica una primera función de transferencia al color lineal submuestreado en el primer espacio de color para obtener un color no lineal submuestreado en el primer espacio de color. Se aplica una primera transformación de color al color no lineal submuestreado en el primer espacio de color para obtener un primer valor de componente croma no lineal submuestreado y/o un segundo valor de componente croma no lineal submuestreado en un segundo espacio de color. Un valor de componente luma no lineal en el segundo espacio de color se deriva para el pixel, que junto con los valores de componente croma no lineales submuestreados representan un color del pixel. El pre-procesamiento reduce los artefactos de croma que de otro modo podrían ocurrir cuando se lleve a cabo un submuestreo de croma después de la aplicación de la primera función de transferencia y la primera transformación de color.
