Abstract
An image processing device for gas detection performs image processing on infrared images obtained by shooting an object to be monitored for a gas leak at a plurality of time points. The image processing device for gas detection includes an image processing unit that performs a process of removing, from image data indicating the infrared images, second frequency component data that is lower in frequency than first frequency component data indicating a temperature change caused by the leaking gas, and indicates a background temperature change of the object to be monitored.
