Abstract: In a signal processing circuit, an input terminal is configured to receive an analog signal output from an avalanche photodiode operating in Geiger mode. A comparison circuit outputs a signal based on a component exceeding a threshold among components a signal input to the comparison circuit. The adjustment circuit includes an AC coupling unit, a level shifter unit, and a reference value adjustment unit. The AC coupling unit establishes AC coupling between the input terminal and the comparison circuit. The level shifter unit adjusts the voltage of the signal input to the comparison circuit to a value lower than a reverse bias voltage applied to the avalanche photodiode. The reference value adjustment unit adjusts the reference value of the signal input to the comparison circuit.

Abstract: The pulse width of light from a pulsed light source 1 is stretched by a stretching element 2 such that an elapsed time and the wavelength of the light in the pulsed light correspond to each other on a one-to-one basis, and the stretched light radiates to an object S. The output of a light receiver 4 that has received light from the object S is digitized by an AD converter 6 and the digitized signal is supplied to a calculation means 5. A trigger signal generated by a trigger signal generator 7 in response to the rise of the pulsed light is delayed by a trigger delay section 74 and supplied to the AD converter 6 after the completion of a dead time T3.

Abstract: A vehicular cabin monitoring system includes a camera disposed within a cabin of a vehicle. Image data captured by the camera is transferred to and is processed at an electronic control unit (ECU). A light emitter that, when electrically operated to emit nonvisible light, illuminates at least a portion of the interior cabin that is viewed by the camera with nonvisible light. The vehicular cabin monitoring system, via processing at the ECU of image data captured by the camera and transferred to the ECU, determines illuminance of nonvisible light at a region of interest within the illuminated portion of the interior cabin that is viewed by the camera. The vehicular cabin monitoring system, responsive to determining that the illuminance of nonvisible light at the region of interest is greater than a threshold illuminance, reduces intensity of nonvisible light emitted by the light emitter.

Abstract: A method for temperature calibration and determination of a temperature in a scene. At each time point out of a plurality of time points in a first period of time, collecting an ambient temperature representing a temperature at a first part of the scene and collecting thermal image sensor signal values corresponding to the collected ambient temperatures and relating to the first part. Determine a calibration function based on the collected ambient temperatures and the thermal image sensor signal values corresponding to each of the collected ambient temperatures. In a second period of time, capturing a thermal image of the scene comprising thermal image sensor signal values relating to a second part of the scene and determine a temperature at the second part of the scene based on the calibration function and based on thermal image sensor signal values comprised in the thermal image.
