Abstract: This gas leak position estimation device is provided with a specifying unit and a first determination unit. The specifying unit specifies a gas region image indicating a region in which the gas hangs in an image obtained by photographing a monitoring region. The first determination unit determines a pixel indicating a gas leak estimated position estimated to be a position at which the gas is leaking out from a plurality of pixels constituting an outline of the gas region image.

Abstract: A gas monitoring image recording device, a gas monitoring image recording method, and a gas monitoring image recording program according to the present invention involve: acquiring gas monitoring image data including a plurality of time-series images for use in monitoring a gas leak; extracting a leakage candidate area as a candidate for a gas leak based on the gas monitoring image data acquired; extracting predetermined features related to the gas leak in response to extracting the leakage candidate area; and causing a storage unit to store the features extracted in association with the gas monitoring image data from which the leakage candidate area has been extracted.
