ELECTRONIC DEVICE INCLUDING IRIS CAMERA

According to various example embodiments of the present disclosure, an electronic device (101) includes: a light source module (420) comprising a light source and associated circuitry; an iris camera (410) configured to capture an iris of a user using infrared rays radiated from the light source module; and a processor (120, 210, 460) electrically connected with the light source module (420) and the iris camera (410) and configured to generate an image regarding the iris. When a user is located at a distance within a specified range from the electronic device (101), the light source module (420) and the iris camera (410) are arranged such that a distance between the light source module (420) and the iris camera (410) is between a first threshold distance and a second threshold distance, the first threshold distance for generating a retina reflection region to have a specified size in the image of the iris, which is obtained by detecting, by the iris camera, the infrared rays reflected from a user's retina, the second threshold distance for generating a darkest portion to be displayed in an iris region in the image of the iris to have specified luminance.
