Remote-controlled receiver

摘要

An infrared remote-controlled receiver of the type comprising an infrared sensing element for receiving a signal transmitted by means of infrared radiation, and an amplifier for amplifying the signal detected by the sensing element, is further provided with detecting means for detecting the ambient luminance of the receiver (an interference signal) and gain control means for supplying the output signal of the detecting means to the amplifier to control its gain in accordance with the ambient luminance of the receiver.
