Patent attributes
An electronic apparatus includes a photodetector element for receiving an infrared signal transmitted from a remote controller and outputting a received signal, a conversion unit for converting the received signal outputted from the photodetector element into a binarized pulse signal and outputting the signal, a decode unit for converting the pulse signal outputted from the conversion unit into code data and outputting the code data, and a control unit for performing a control operation in accordance with the code data. The electronic apparatus further includes a measuring unit for measuring a pulse width of a pulse signal outputted from the conversion unit in a state where the infrared signal from the remote controller is not received at the photodetector element, and a judging unit for judging whether the pulse width measured by the measuring unit is equal to or longer than a predetermined time for determining a stable reception environment.
