とを特徴とする請求(1) In a television receiver that controls at least one of brightness, contrast, and color saturation according to the surrounding brightness, an amorphous silicon photosensor is used as the brightness detection element. A color television receiver that controls the impedance of a semiconductor element according to the output voltage of this optical sensor to generate a variable DC voltage, and controls a video amplifier circuit or a chroma amplifier circuit according to this DC voltage. A claim characterized in that the variable direct current voltage is obtained from one end of the high potential side of the resistor.
