Abstract

Los presentes principios se refieren a un método y dispositivo para mapeo de gama desde una primera gama de color hacia una segunda gama de color. El método comprende obtener un color clave preservado (prsv_color K0) y un ángulo de alineación de tono (?K0) del color clave (color K0) para cada color clave (color K0) de al menos 3 colores clave para definir una gama preservada y una gama rotada; y realizar un mapeo de tono de un color actual (color) desde la primera gama de color hacia la segunda gama de color en donde en caso que el color actual (color) esté en un área preservada definida por el color clave preservado (prsv_color K0), el medio del color actual mapeado está sin cambios, y en el caso que el color actual esté fuera de la gama preservada, el tono del color actual mapeado es calculado desde el ángulo de alineación del tono (?K0) de dos colores clave adyacentes del color actual (gama rotado) y desde el área preservada.
