Abstract
The gas detection device according to the present invention is provided with: a first image processing unit for generating a first binary image for indicating in binary fashion the inside and outside of a first region indicating water vapor and a gas to be detected, on the basis of a first image generated using an optical filter having a first pass wavelength band including at least an absorption wavelength band of the gas; a second image processing unit for generating a second binary image indicating in binary fashion the inside and outside of a second region indicating the water vapor, on the basis of a second image generated using an optical filter having a second pass wavelength band different from the absorption wavelength band; and a third image processing unit for calculating a difference between the first binary image and the second binary image.
