Abstract
A gas-detection image processing device includes first, second, and third processors. The first processor generates a plurality of first images by applying processing to extract a gas candidate region to each of a plurality of infrared images captured in time series during a predetermined period. The second processor generates a second image, while using the first images, by applying processing to extract an appearance region indicating that a gas candidate region has appeared in at least a part of the predetermined period. The second processor generates two or more second images by applying the processing to extract the appearance region to the first images generated in a manner corresponding to two or more of the predetermined periods respectively. The third processor generates a third image by applying processing to extract a common region of the appearance regions while using the two or more of the second images.
