An electronic device according to an embodiment comprises: a front plate; a housing comprising a rear plate facing the front plate; a display exposed through at least one part of the front plate; a camera exposed through a first part of the rear plate; a plurality of first light-emitting diodes exposed through a second part of the rear plate near the first part; a processor operatively connected to the display, camera and plurality of first light-emitting diodes; and memory operatively connected to the processor. The memory, during execution, delays an imaging point by designated time and confirms whether or not a first function of imaging a still image has been configured if the processor receives a first input associated with imaging of the still image by means of the camera, and can store instructions, for guiding with respect to a degree in which the imaging point is reached, by means of the plurality of first light-emitting diodes if the first function has been configured.
