    Abstract: An electronic device and a method for providing information of a foreign substance adsorbed from the outside of a camera are provided. The electronic device includes a transparent member formed with a first medium, a light emitter disposed under the transparent member and configured to emit light, a camera disposed under the transparent member and configured to obtain an image of an external object, and a processor. The processor may be configured to obtain a first image of the external object by using a difference of light refracting angles between the first medium and the second medium formed at an outer part of the transparent member by using the camera while at least one part of the light emitted by the light emitter is transmitted through an inner part of a second medium, obtain a second image of the external object by using the camera, and provide foreign substance information of a third medium adsorbed on at least one part of an outer surface of the transparent member by using a color difference between at least one partial area of the first image and at least one partial area of the second image.

    Abstract: An electronic device and noise canceling method thereof is provided. The electronic device may include a housing; at least one output circuit arranged inside the housing and configured to generate a first signal; an opening formed on one side of the housing; a hole connected to the opening; a receptacle arranged inside the hole, and configured to receive an external connector, and electrically connected to the at least one output circuit; at least one sensor arranged within a predetermined proximity range to at least one of the opening and the receptacle; and a control circuit electrically connected electrically to the at least one output circuit, the receptacle, and the at least one sensor, wherein the control circuit is configured to detect the external connector approaching to at least one of the opening and the receptacle using the at least one sensor, to generate a second signal upon detection of the approaching external connector, and to control the at least one output circuit to change the first signal at least partly based on the second signal.
