Abstract

La presente invención se refiere a un dispositivo de codificación de video y método para recibir una imagen asociada a un primer espacio de color, en donde la imagen comprende un primer componente en una primera ubicación de muestreo (C0), un segundo componente en una segunda ubicación de muestreo (L0) y el segundo componente en una tercera ubicación de muestreo (L4). Un primer filtro de interpolación se aplica al segundo componente en la segunda ubicación de muestreo (L0) y el segundo componente en la tercera ubicación de muestreo (L4) para determinar el segundo componente en la primera ubicación de muestreo (L(C0)). El segundo componente en la primera ubicación de muestreo L(C(0)) puede asociarse al primer espacio de color. Un modelo de conversión de color se aplica al primer componente en la primera ubicación de muestreo (C0) y al segundo componente en la primera ubicación de muestreo (L(C0)) para convertir el primer componente en la primera ubicación de muestreo en un segundo espacio de color.
