Abstract: Disclosed are various embodiments related to iris authentication technology for electronic devices. According to an embodiment of the present disclosure, an electronic device may include a camera, a display, and a processor configured to display a first image on the display when a distance between the electronic device and an object included in an image captured by the camera is a first distance and to display a second image associated with the first image on the display when the distance between the electronic device and the object included in the image captured by the camera is a second distance different from the first distance. Other various embodiments are also available.

Abstract: A method includes detecting whether a cover covers the at least one portion of the display, receiving a call signal, displaying an information related to the reception of the call signal on the at least one portion of the display in response to the reception of the telephone call reception signal, detecting an external object that is adjacent to a surface of the display, and connecting a call in response to the detection of the adjacency of the external object. An electronic device includes a controller configured to cause the display to display receiving a call through the window in response to receiving the call while the cover is detected to cover the display, and control the call to be connected in response to detecting an external object that is adjacent to a surface of the display.
