Abstract
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 are provided in one common mold package. The remote control receiver includes a first signal processing circuit for adding up signals outputted by the plurality of light-receiving regions and, based on a resulting signal, demodulating and outputting the remote control signal. The remote control receiver also includes 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.
