An ultraviolet sensor, a reading out circuit for the ultraviolet sensor, and an image sensor including the ultraviolet sensor are provided to output a signal corresponding to the intensity of an ultraviolet ray without an additional wiring by using blanking time. An image sensor includes a pixel array(20), an ultraviolet sensor(30), and a peripheral circuit(40). The pixel array part is positioned in an irradiation area to output an image signal corresponding to an incident visible ray. The ultraviolet sensor is positioned in the irradiation area to output an ultraviolet signal corresponding to the intensity of an incident ultraviolet ray. The peripheral circuit controls the pixel array part, and processes and outputs the image signal and the ultraviolet signal. The irradiation area receives light passing through the same optical system. The ultraviolet signal includes a current corresponding to the intensity of light including an ultraviolet ray and includes a current corresponding to the intensity of light from which the ultraviolet ray is removed.
