Abstract

Se proporciona una unidad de retroiluminación, un aparato de visualización, y un método de control de la unidad de retroiluminación. La unidad de retroiluminación incluye una unidad de extracción de información de profundidad de imagen configurada para extraer la información de profundidad de imagen de una señal de imagen y un calculador de brillantez configurado para calcular las brillanteces que corresponden con la información de profundidad de imagen. La unidad de retroiluminación mejora los efectos de tres dimensiones en una imagen controlando las brillanteces de los dispositivos de emisión de luz de acuerdo con las brillanteces calculadas de manera que corresponden con la profundidad de imagen.
