Abstract: A physical quantity sensor includes a detection circuit that outputs a detection value indicating a physical quantity applied to a detecting element and a correction processor that corrects the detection value to output a corrected value. The correction processor causes the corrected value to be substantially 0 (zero) if all of conditions that an absolute value of a time-differentiated value of the detection value is not larger than a predetermined differential threshold and that an absolute value of the corrected value is not larger than a predetermined output threshold are satisfied. This physical quantity sensor prevents the output signal from changing due a temperature change in spite of a small number of components.

Abstract: An infrared processing system includes a first thermal image generating unit, an object extracting unit, a second thermal image generating unit, and an object temperature calculating unit. The first thermal image generating unit generates, using a first temperature correction value, a first thermal image based on the output signal of the image sensor. The object extracting unit extracts the object from the first thermal image. The second thermal image generating unit generates, using a second temperature correction value corresponding to the object that has been extracted by the object extracting unit, a second thermal image based on the output signal of the image sensor. The object temperature calculating unit calculates, based on the second thermal image that has been generated by the second thermal image generating unit, a temperature of the object that has been extracted by the object extracting unit.

Abstract: A temperature sensing system senses a temperature in the monitor space. The temperature sensing system includes a first detector, a second detector, and a processing unit. The first detector detects a temperature on a ceiling and outputs first information about the temperature on the ceiling. The second detector detects infrared radiation emitted from a floor and outputs second information about the infrared radiation from the floor. The processing unit calculates, based on at least the first information and the second information, a spatial temperature distribution which includes a component in a height direction with respect to the monitor space between the ceiling and the floor.
