Abstract
According to various example embodiments of the present disclosure, an electronic device includes: a light source module comprising a light source and associated circuitry; an iris camera configured to capture an iris of a user using infrared rays radiated from the light source module; and a processor electrically connected with the light source module and the iris camera 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, the light source module and the iris camera are arranged such that a distance between the light source module and the iris camera 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.
