Generally, the living environment is dimmer at night; therefore, it is possible for thieves invade our house at this time and increase the crime rate. Accordingly, light is necessary in the living environment but moving object will cause a wrong judgment when wisdom supervisory system detect the moving object. The main reason is moving object will be affected by multi-light environment and project several shadow. For this purpose, this research is about eliminating objective shadows in order to make wisdom supervisory system can precisely detect the moving object. The light sources mainly come from the white and yellow lights which we usually see in general living environment. Before the research, the procedure is to adjust different color of light, create different shadow modes of impenetrable object, and automatically judge the characteristics of environmental light by shadow projection of corrector.
