摘要： In an infrared-rays detector, a pyroelectric element detects existence or movement of a human body, and the output signal of the pyroelectric element is converted to a voltage signal. Then, the voltage signal is subjected to waveform analysis. Then, a detection signal is outputted only when a waveform generated by a human body is detected by the waveform analysis. For example, the voltage signal is amplified at two different frequency ranges, and the amplified signals are used for discriminating a signal due to a human body. Then, a noise such as a popcorn noise of the pyroelectric element is prevented to be detected erroneously as generated by a human body.

摘要： A photodetector is provided, which has the capability of preventing a reduction in dynamic range for a signal light even under a plenty of environmental light to stably obtain a received light output. This photodetector has an accumulation electrode and a holding electrode, which are formed on a photoelectric converting portion through an insulating layer, and a control unit for controlling timings of applying voltages to these electrodes and polarities of the voltages. One of electrons and holes generated in the photoelectric converting portion is accumulated in an accumulation region formed by applying the voltage to the accumulation electrode, and the other is accumulated in a holding region formed by applying the voltage to the holding electrode. Then, the electrons and holes accumulated in the accumulation region and the holding region are recombined, so that remaining electrons or holes not recombined are output.
