PURPOSE: An optical sensor with a color sensor and a clear sensor for blocking infrared light is provided to efficiently distinguish visible light and infrared light from an output signal of the sensor. CONSTITUTION: An optical sensor with a color sensor and a clear sensor for blocking infrared light comprises a first filter(104), a first color sensor(106), a clear sensor(110), and a light intensity calculator(112). The first filter has a substrate for blocking visible light and blocks visible light from a light route. The first and clear sensors detect light from the light route. The light intensity calculator calculates visible light from the light route.
