Abstract: A semiconductor device for measuring IR radiation comprising: at least one sensor pixel; at least one reference pixel shielded from said IR radiation comprising a heater; a controller adapted for: measuring a responsivity by applying power to the heater, while not heating the sensor pixel; measuring a first output signal of an unheated pixel and a first reference output signal of the heated pixel, obtaining the responsivity as a function of a measure of the applied power to the heater and of the difference between the first output signal and the first reference output signal; applying a period of cooling down until the temperature of the reference pixel and the sensor pixel are substantially the same; generating the output signal indicative of the IR radiation, based on the difference between the sensor and the reference output signal, by converting this difference using the responsivity.

Abstract: Flight based infrared imaging systems and related techniques, and in particular UAS based thermal imaging systems, are provided to improve the monitoring capabilities of such systems over conventional infrared monitoring systems. An infrared imaging system is configured to compensate for various environmental effects (e.g., position and/or strength of the sun, atmospheric effects) to provide high resolution and accuracy radiometric measurements of targets imaged by the infrared imaging system. An infrared imaging system is alternatively configured to monitor and determine environmental conditions, modify data received from infrared imaging systems and other systems, modify flight paths and other commands, and/or create a representation of the environment.

Abstract: A signal component amount calculation unit calculates dispersion or standard deviation of multiple times of infrared detection signals detected by each detector element to be processed, and calculates the amount of a signal component dependent on infrared rays incident on the infrared detector included in the infrared detection signals, on the basis of the calculated dispersion or standard deviation. A fixed pattern noise calculation unit calculates the amount of a fixed pattern noise component on the basis of the infrared detection signals and the calculated amount of a signal component. A data update unit updates the fixed pattern noise data with the calculated amount of a fixed pattern noise component.

Abstract: A electronic device includes a pyroelectric element that senses a thermal change, a detector, and a controller. The detector detects the movement of the subject based on a detection signal output from the pyroelectric element. The controller sets detection sensitivity of the detector based on a result of the detection by the detector. The detection sensitivity is set to low sensitivity or high sensitivity. The controller sets the detection sensitivity to the high sensitivity when the detector has detected the movement of the subject. The controller sets the detection sensitivity to the low sensitivity when a predetermined period has elapsed without the detector detecting the movement of the subject in the state where detection sensitivity is the high sensitivity.
