摘要：
A television device structured to automatically adjust the color temperature on the display screen in accordance with the viewing environment includes an external light detection unit or an optical sensor for detecting the illuminance and the tint of the ambient light, and an image quality control unit or a microcomputer for adjusting quality of the video image to be displayed on the display panel. The image quality control unit adjusts the color temperature of the video image to be displayed in accordance with the illuminance value and the tint value detected by the external light detection unit. The optical sensor includes an illuminance sensor for mainly detecting the visible light, and an infrared sensor for mainly detecting the infrared light. The illuminance value and the tint value are obtained based on the output values of those two sensors.
