Abstract
A fin de proporcionar un dispositivo de visualización de cristal líquido capaz de reducir la ocurrencia de múltiples contornos en la visualización de una imagen en movimiento hasta el mínimo, el ciclo de ejecución de una operación intermitente de iluminación en el procesamiento de exploración de retroiluminación y el ciclo de una señal de sincronización vertical son realizados iguales cuando es ejecutado un modo de inserción de imagen de interpolación en el cual una señal de imagen de interpolación generada en función de dos o más imágenes continuas de cuadro es insertada entre cuadros y es escrita en un panel de cristal líquido, y el ciclo de ejecución de la operación intermitente de iluminación en el procesamiento de exploración de retroiluminación se hace más largo que el ciclo de la señal de sincronización vertical (o es desactivado el procesamiento de exploración de retroiluminación) cuando es ejecutado un modo de salida de imagen superpuesta en el cual la misma imagen de cuadro es escrita en el panel de cristal líquido, de manera continua, n veces.
