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.

Abstract: An image processing device performing image processing on images obtained by shooting an object to be monitored at a plurality of time points. The image processing device includes a hardware processor that performs a process of removing, from image data indicating the images, second frequency component data that is lower in frequency than first frequency component data indicating a luminance of the object to be monitored, the second frequency component data indicating a background luminance change of the object to be monitored.
