Abstract:
1. An infrared communications receiver configured to be used with a display device including a light source, the receiver comprising: a first light-receiving element configured to receive an externally transmitted infrared signal and output a first signal; a second light-receiving element disposed in the vicinity of the light source configured to at least receive infrared light or visible light emitted by the light source and output a second signal; and a reduction portion configured to reduce a noise component in the first signal based on the second signal, the noise component being derived from the infrared light emitted by the light source, the reduction portion including, when the light source is determined as being driven by pulse width modulation drive by the determination portion, the frequency filter portion reduces an abrupt noise element in a data signal based on the threshold being set, the abrupt noise element being derived from the infrared light emitted by the light source.
