摘要： An infrared detecting device. The device includes a drive power supply circuit which supplies a drive current to each of signal circuits comprised of an I/V conversion circuit, a voltage amplification circuit, a detection circuit and an output circuit. The drive power supply circuit is comprised of a current generating circuit and a distribution circuit. The current generating circuit includes a reference current source, a fixed current source which provides a fixed current based on reference current and a variable current source which provides a variable current stepped up or down to any of different currents based on the reference current. The distribution circuit distributes the drive current to a part of the signal circuits based on the current from the fixed current source and distributes the drive current to a remaining part of the signal circuits based on the current from the variable current source. The device reduces current consumption while keeping the performance or behavior of the circuits in stable state.

摘要： A spatial information detection device is provided, which is capable of, even under the condition that an environmental light having intensity fluctuations exists in a target space, projecting a light intensity-modulated with a predetermined modulation signal from a light emitting source into the target space, receiving light from the target space with a photodetector, and detecting spatial information of the target space from a change between the light projected from the light emitting source and the light received by the photodetector. This device has a smoothing unit configured to integrate, over a predetermined integration period, a fluctuation component in a prescribed phase zone of the modulation signal with respect to an electric charge amount generated by receiving the environmental light in the electric charge amount generated at the photodetector by receiving the light from the target space, thereby smoothing the fluctuation component.

摘要： An object detecting device utilizes a pyroelectric sensor providing a sensing current, a voltage amplifier providing an amplified voltage proportional to the sensing current, and a level monitor providing a detection signal when the amplified voltage exceeds a detection threshold. The device has a standby mode where the voltage amplifier receives a limited source current to provide the voltage of low amplification, and the level monitor provides a wake-up signal when the low amplified voltage exceeds a preliminary threshold lower than the detection threshold. In response to the wake-up signal, the device is switched to an operation mode where the amplifier receives a rated source current to provide a voltage of high amplification for comparison with the detection threshold. Thus, the amplifier is kept to be less-power consuming in the absence of the wake-up signal, reducing a power requirement.
