る。(Prior Art) Conventionally, a lighting device using visible light of this kind is known to make black stains and oil stains on an object visible. Therefore, with this lighting device, visual work in various industries can be automated by using a video camera or the like as an image processing device and applying image processing technology. For example, it is extremely functional for defect inspection for inspecting the adhesion of scratches, dirt, or surface conditions, 1, ie, for automating the visual inspection of black dirt or oil stains on the object to be inspected.
（発明が解決しようとする問題点）
ところが、このような照明装置では、黒汚れを可視する

。その理由は、可視光による可視範囲が小さいためで、
そのために油汚れの目視作業には、特に高＠度な画像処
理装置が必要となり、従ってその設備費が増大するとい
う問題があった。(Problem to be Solved by the Invention) However, with such a lighting device, although it is possible to make black stains visible, it is also possible to make visible oil stains, which are 100% lighter than the black stains, at the same time as the black stains on the object. It wasn't enough to do that. The reason is that the visible range of visible light is small.
Therefore, visual inspection of oil stains requires a particularly sophisticated image processing device, which poses the problem of increased equipment costs.
