赤外線カメラ
Document Type and Number:
Japanese Patent JP6434227
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an infrared camera capable of miniaturizing hardware configuration and reducing the load of calibration.SOLUTION: The infrared camera includes an imaging part 6 which includes an infrared detection element 6a, a lens 4 which condenses an infrared ray on the imaging part 6, an image data generation part 17 which generates image data from output from the infrared detection element 6a, a reference sensitivity coefficient storage part 15 which stores a reference sensitivity coefficient, a temperature versus average sensitivity information storage part 14 which stores correlation information between an element temperature and an average sensitivity coefficient, an element temperature sensor 7 which detects the temperature of the infrared detection element 6a, a calibration sensitivity coefficient calculation part 13 which calculates a calibration sensitivity coefficient on the basis of the element temperature, the reference sensitivity coefficient, and the correlation information, a calibration sensitivity coefficient storage part 16 which stores the calibration sensitivity coefficient, and a calibration offset coefficient storage part 19 which stores a calibration offset coefficient. The image data generation part 17 processes the output from the infrared detection element 6a by using the calibration sensitivity coefficient and the calibration offset coefficient, to generate the image data including temperature information.
