Abstract: Various embodiments of the present disclosure relate to an apparatus and a method for controlling an optical sensor in an electronic device. The electronic device includes: a light emission element configured to emit light; a first light reception element configured to detect an intensity of light which is reflected from an object based on the light emitted by the light emission element; a second light reception element configured to detect a shape of the object using the light which is reflected from the object based on the light emitted by the light emission element; and a processor. The processor is configured to: control the light emission element to emit light with an intensity corresponding to an operation mode of the electronic device; and receive light which is reflected from the object via the first light reception element or the second light reception element based on the operation mode of the electronic device. Other embodiments are possible.

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.
