Abstract

Aplicar un proceso de mapeo de la gama de color en una primera imagen para generar una segunda imagen, donde el contenido de la primera y segunda imágenes es similar pero los espacios de color respectivos de la primera y segunda imágenes son diferentes, pueden involucrar controlar el proceso del mapeo de la gama de color al menos por medio de un modo de mapeo de la gama de color obtenida de una secuencia de bits donde el modo de mapeo de la gama de color pertenece a un ajuste comprendiendo al menos dos modos preajustados y un modo de parámetros explícitos y, si el modo de mapeo de la gama de color obtenida es el modo de parámetros explícitos y el proceso de mapeo de la gama de color no está habilitado para el modo de parámetros explícitos, controlando el proceso de mapeo de la gama de color por un modo de mapeo de la gama de color sustituto determinado a partir de los datos adicionales.
