摘要
An apparatus and a method for detecting lie are provided to check a psychological state such as tension and amazement of a person to be inspected from the size change of pupils in eyes. An apparatus for detecting lie includes a photograph unit(110), an IR(InfraRed) filter(113), an illumination unit(120), and a fixing unit. The photograph unit takes a photograph of eyes. The IR filter transmits an IR ray to the photograph unit by being installed in front of the photograph unit. The illumination unit emits the IR ray as an IR light source. The fixing unit fixes the illumination unit to face the eyes. The fixing unit maintains the position of the photograph unit uniformly. The apparatus detects the lie by measuring the change of pupil sizes in the eyes.
