This paper depict the system which reacts staly towards light changes, when object is detected using retinex. Previous interaction system does not react to transient light conditions. Since non-lighting condition was constructed in the limited space. However, if interaction contents work in the inside where the light changes, the light input is changed as the time goes by when the system detect objects with super sensitive camera few lighting transients makes system trouble. Thus, lighting is one of the most significant factors of the system.
