Abstract:
1. A remote control receiver comprising: at least a plurality of light-receiving regions for receiving remote control signals, respectively, in a form of incident light and performing photoelectric conversion of the signals in one common mold package, the remote control receiver further comprising: a first signal processing circuit for adding up signals outputted by the plurality of light-receiving regions and, based on resulting signals, demodulating and outputting the remote control signals; a second signal processing circuit for calculating a difference between the signals outputted by the plurality of light-receiving regions to obtain and output a directional signal representing a direction in which the incident light has been incident on the plurality of light-receiving regions; and an external input terminal for turning on or off power supply to the second signal processing circuit so that the second signal processing circuit is powered only when the first signal processing circuit outputs the remote control signal.
