Abstract: An electronic device including an optical module, a method of operating the electronic device including the optical module, and a non-transitory computer-readable recording medium having recorded thereon a program for performing the method. The electronic device includes an optical module configured to project content on a projection surface and a processor configured to determine whether the electronic device is positioned within a predetermined range of a projection surface and control the optical module to project the content onto the projection surface based on the determination.

Abstract: Disclosed is an electronic device including a first communication circuit that perform communication by using a first communication protocol, and a processor electrically connected to the first communication circuit, wherein the processor activates the first communication circuit based on a predetermined mutual operation, sets an operating mode of the electronic device based on at least part of the activation of the first communication circuit, and operates a universal serial bus (USB) host controller through a switching circuit based on the set operating mode.

Abstract: A method of operating an electronic device is provided, which includes comparing gain values acquired on the basis of voices collected from at least two microphones, determining at least one speaker included in a displayed content on the basis of the compared gain values, and displaying a voice of the determined speaker in a text format in an area of a display around the determined speaker.

Abstract: A method for recognizing an image in an electronic device is provided so as to determine whether or not a specific object is actually within the presence of immediate photographable vicinity) of the electronic device based on certain characteristics of one or more images of the specific object. Images of the specific object which is focused and shot at different magnifications are obtained. Characteristics of an object region and a background region between the obtained images are compared. Whether the object is real is determined depending on the comparison result. An apparatus hardware configured for operation of the method in electronic devices including but limited to mobile terminals.

Abstract: A three dimensional camera device and a method of controlling the same are provided. The three dimensional camera device and the method enable a user to photograph a three dimensional image suitable for a photographing angle. Since a swing hinge rotates a left camera element and a right camera element about a mid-point between the left camera element and the right camera element, a user may photograph a three dimensional image suitable for a photographing angle.

Abstract: A method and apparatus for providing information about a plurality of wireless charging pads to an electronic device such that the electronic device performs wireless charging efficiently is provided. The method includes receiving information about the plurality of wireless charging pads and displaying the information about the plurality of wireless charging pads on a screen of the electronic device.

Abstract: Security management in an electronic device is provided. An method of the electronic device includes displaying an icon of an application having a first security level in a first region which occupies part of an interface, and displaying an icon of an application having a second security level in a second region which occupies an exclusive part of the first region.

Abstract: An earphone device and a method for operation saves power and time when a user is interrupted from listening to communications. The earphone device includes a cable of a predetermined length, an ear jack, an earphone, a light sensor, and a controller. The ear jack is installed at one end of the cable, and is preferably arranged into an ear jack hole provided in a terminal for providing sound or voice reproduction. The earphone is installed at the other end of the cable and includes a speaker, and preferably inserted into and/or on a user's ear. The light sensor is positioned to periodically sense brightness. The controller determines whether or not the earphone is actually in use (or non-use) based on the brightness periodically sensed by the light sensor. The transmission of audio signals to the earphone is enabled/disabled according to the determination by the earphone.

Abstract: An apparatus and method for implementing an application using solar battery charging of a portable terminal are provided. The method includes determining the accumulated charging time of the solar battery, extracting an image corresponding to the determined accumulated charging time of the solar battery from a storage unit, and displaying the extracted image on a display unit. Accordingly, a user may be entertained by plant growing at the same time of charging the solar battery.
