An electronic device includes a communication module for supporting short-range wireless communication; a camera module for capturing a video; a display for displaying the video being captured; and a processor operatively connected to the communication module, camera module, and display. The processor may be configured to: connect with the external electronic device using the communication module; receive an audio signal from the external electronic device at the same time as the capturing of the video; confirm a target object among at least one object included in the video being captured; confirm first location information about the location at which the target object is displayed on the display; estimate, on the basis of the first location information, the actual location of the target object; generate second location information about the actual location; and process the audio signal on the basis of the generated second location information.
