から構成してなる赤外線受光装置。An amplifier circuit that amplifies an electrical signal extracted by photoelectric conversion from a light receiving section that selectively receives infrared rays among light beams, and a light receiving element that receives ambient light of the light receiving section and whose output changes depending on the amount of light received. and a gain control circuit that changes the gain of the amplifier circuit according to the output of the light receiving element and reduces the gain when the amount of ambient light is large, thereby suppressing the level of photonoise passing through the amplifier circuit. An infrared receiver.
