PROBLEM TO BE SOLVED: To provide a human body detector capable of detecting body movement as usual and stably without detecting the fluctuation of reflection light of lamp reflected on water surface in a bath by the human body sensor as movement. SOLUTION: Before going into the operation of the movement, only prominent pixel data was replaced with another pixel data and then operation of movement was performed to determine yes/no of human movement. Thus, such abnormal data as the reflection light of water surface in the bath can be excluded and erroneous detection can be prevented since the fluctuation by reflection light is not detected as movement. Furthermore, by replacing only prominent pixel data with another data, decision of usual motion and stop of human body can be sensitively conducted without lowering the movement. |
