Abstract
Se proporciona un dispositivo de pantalla de cristal líquido y un receptor de televisión que permiten una mejora en visibilidad en un intervalo de tono bajo en una configuración en la cual se cambia el brillo de una luz trasera sobre la base de una información de brillo que se relaciona con una imagen, el dispositivo de pantalla de cristal líquido está provisto con una unidad de establecimiento de curva APL y una unidad de modulación de brillo de histograma que ajusta el brillo de la luz trasera y una señal de tono sobre la base del brillo promedio de la imagen y el histograma del brillo de la imagen, y una unidad de extensión negra con corrección gama de la señal de tono ajustada por la unidad de modulación de brillo de histograma sobre la base de un valor gama previamente establecido, en donde una característica gama utilizada para la corrección gama en la unidad de extensión negra se establece, sobre la base de información de correspondencia que indica la relación de correspondencia entre una combinación del brillo de luz trasera ajustada por la unidad de modulación de brillo de histograma y la iluminación ambiental del sitio de instalación de un panel de cristal líquido, y una pluralidad de valores gama (?2.0-2.4), al seleccionar un valor gama correspondiente a la combinación.
