## Abstract

An electronic device and control method thereof capable of utilizing a display as illumination light for a camera that is being used to capture images is provided. The electronic device includes a foldable display; a camera; a processor; and a memory operatively connected to the processor, wherein the memory may store instructions that cause, when executed, the processor to detect a user input for activating the camera; identify a state of the foldable display based on the user input; display a live view of an object obtained by the camera through a designated region of the foldable display based on a first state of the foldable display; divide the foldable display into a first region for a live view and a second region for a lighting plate with respect to a folding site based on a second state of the foldable display; display a live view of an object obtained by the camera based on the first region; and output illumination light based on the second region.
