IMAGE PROCESSING DEVICE FOR GAS VISUALIZATION, IMAGE PROCESSING METHOD FOR GAS VISUALIZATION, IMAGE PROCESSING PROGRAM FOR GAS VISUALIZATION, AND, GAS DETECTION SYSTEM

摘要

To prevent erroneous detection, and visualize gas even if gas leakage is small.SOLUTION: An image processing device for gas visualization (main body section 3) includes: an image processing section 13 for generating a visualization image Im2 by performing image processing of visualizing gas for an image in a monitoring area, which is photographed by an imaging device (infrared camera 2); a sensitivity setting section 14, in which the gas is easily visualized in the image processing when gas detection sensitivity is set high, the gas is hardly visualized in the image processing when the gas detection sensitivity is set low, and the gas detection sensitivity is set higher than before detection when a non-image type gas detection device 21 installed in the monitoring area detects the gas; an image output section (a display control section 16, a display 17) for outputting the visualization image Im2 generated by the image processing section 13 under a state that the gas detection sensitivity is set high.SELECTED DRAWING: Figure 1A
