Abstract

Cuando una pantalla de gama ancha de color visualiza video en función de una señal de video que cumple con el estándar de intervalo más angosto de reproducción de color, con el propósito de cumplir el uso de la característica de la pantalla de gama ancha de color capaz de visualizar colores rojos altamente saturados y vividos mientras se elimina el problema de observar imágenes resplandecientes en la parte de la región de color rojo junto a la brillantez y saturación más alta, un circuito de procesamiento de video (2) reduce y corrige el valor de señal de la señal de video de entrada, que representa los colores dentro del intervalo de color que será corregido, el cual se encuentra dentro de un intervalo específico de saturación de la saturación más alta a la saturación intermedia dentro de un intervalo específico de tonalidad centrado en la tonalidad roja en el intervalo de reproducción de color (un intervalo extendido de reproducción de color más ancho que el intervalo de reproducción de color de estándar sRGB) de un panel de cristal líquido (4) y que se encuentra dentro de un intervalo específico de brillantez de la brillantez más alta a la brillantez intermedia en el interior de este intervalo, de modo que la saturación de brillantez de la misma cambian a la saturación y brillantez dentro de un intervalo predeterminado intermedio de color entre el intervalo extendido de reproducción de color y el intervalo de reproducción de color del estándar del cual cumple la señal de video de entrada.
