で補正することを特徴とする赤外線撮像装置。 An infrared lens for condensing and combining incident infrared light, a two-dimensional array of infrared detectors that photoelectrically converts the formed infrared light image, and further reads it out as a serial electrical signal, and each of the infrared detectors. In an infrared imaging device that is composed of a correction section that corrects variations in pixel sensitivity and a gimbal section that mounts an optical lens and an infrared detector, a gimbal is attached to the correction section while taking in infrared light from the scene to be imaged. An infrared imaging device that takes in sensitivity variation data of an infrared detector corresponding to multiple fields of view while moving and corrects it using an averaged value.
