Abstract:
The infrared imaging device includes an optical system, an infrared detector that captures an infrared image, a correction unit that corrects an infrared image based on basic correction data and outputs a corrected image, and an offset value calculation unit. The offset value calculation unit detects a subject region from the corrected image, calculates a subject value indicating a pixel value of a subject region, and calculates a subject value change amount which is a change amount of a pixel value of the subject region based on the reference subject value and the calculated subject value, and calculates the subject value change amount, as a representative offset value indicating a change amount of each pixel value of a plurality of pixels caused by a temperature change.

Claim (Index 20):
A signal correction method using an infrared imaging device including an infrared detector which is positioned on an image forming surface of an optical system and includes a plurality of pixels which detects incident infrared rays, the method comprising:\n a capturing step of capturing an infrared image by using the plurality of pixels; a correction step of correcting the infrared image and outputting a corrected image based on basic correction data for correcting unevenness for each pixel of the plurality of pixels; and an offset value calculation step, wherein the offset value calculation step has a region detection step of detecting a subject region corresponding to a target subject from the corrected image, a pixel value calculation step of calculating a subject value indicating a pixel value of the subject region, a change amount calculation step of calculating a subject value change amount which is a change amount of the pixel value of the subject region based on the subject value and a reference subject value which is the pixel value of the subject region on a corrected reference image acquired by correcting a reference infrared image which is an infrared image which is a reference captured by the infrared detector based on the basic correction data, and a representative offset value calculation step of calculating the subject value change amount, as a representative offset value indicating a change amount of each pixel value of the plurality of pixels caused by a temperature change, and in the correction step, the infrared image is corrected based on the representative offset value and the basic correction data.
