Description
そこで、表示制御部７２２により合成画像が作成されると、判定部７２３は、赤外線画像において周辺よりも予め決められた温度（例えば5℃）以上、低温である領域（隣接する所定数以上の画素に対応する領域）が存在するか否かを判定する。そして、周辺よりも低温である領域が存在している場合には液漏れが生じていると判定し、表示部７４に表示されている画像の該当箇所に所定の印を表示するとともに、液漏れが生じている旨のメッセージを表示する。ここでは判定部７２３が合成画像に基づいて液漏れの有無を判定する構成としたが、もちろん、使用者が自ら表示部７４に表示される合成画像を確認して液漏れを判定することもできる。 Therefore, when the composite image is created by the display control unit 722, the determination unit 723 determines that the infrared image has a temperature (for example, 5 ° C.) or higher that is predetermined and lower than the surroundings (for example, adjacent predetermined number or more pixels). It is determined whether or not the region corresponding to) exists. Then, when a region having a temperature lower than the surrounding area exists, it is determined that a liquid leak has occurred, a predetermined mark is displayed at the corresponding portion of the image displayed on the display unit 74, and the liquid leak is displayed. Display a message to the effect that Here, the determination unit 723 is configured to determine the presence or absence of liquid leakage based on the composite image, but of course, the user can also check the composite image displayed on the display unit 74 and determine the liquid leakage. ..
