An operating method of the electronic device includes detecting, at least one of two or more first sensors disposed in a preset region, detecting an amount of charge transfer over a preset value, when detecting the amount of the charge transfer over the preset value, detecting, at one of two or more second sensors disposed in a preset distance from two or more microphones, an object in a preset distance; and collecting, at one of the two or more microphones, the one disposed in a preset distance from the second sensor detecting the object in the preset distance, a voice. | 05-01-2014 |
20140168494 | ELECTRONIC DEVICE AND METHOD FOR DRIVING CAMERA MODULE IN SLEEP MODE - A method for operating an electronic device which is in a first mode is provided. The method includes detecting a grip state of the electronic device, detecting a change in tilt when the detected grip state is equal to or greater than a predetermined value, and switching a mode from the first mode to a second mode when the detected change in tilt is within a set tilt range. | 06-19-2014 |
20150249193 | LIGHT EMITTING DEVICE PACKAGE HAVING PHOSPHOR LAYER AND METHOD OF FABRICATING THE SAME - Provided are light emitting device package having a phosphor layer and a method of fabricating the same. A package substrate having a wiring pattern is disposed. A light emitting device mounted on the package substrate is disposed. The light emitting device has a main body having a light emitting layer therein. The light emitting device has an upper electrode on an upper surface of the main body. A bonding wire is connected to the upper electrode and the wiring pattern. A phosphor layer is formed on the light emitting device. The phosphor layer has a recessed space to accommodate the upper electrode and the bonding wire. The phosphor layer covers a side surface of the light emitting device. | 09-03-2015 |
20150324569 | FINGERPRINT RECOGNITION METHOD AND ELECTRONIC DEVICE PERFORMING THEREOF - A fingerprint recognition method and electronic device performing the same are provided. The electronic device includes a fingerprint sensor configured to perform fingerprint sensing according to a control signal of a processor, and includes the processor configured to obtain a fingerprint-unrecognizable position from a sensing area of the fingerprint sensor, to obtain, based on the fingerprint-unrecognizable position, a distance to a fingerprint from the fingerprint-unrecognizable position, and to control, based on the distance, the fingerprint sensor by adjusting a sensing operation of the fingerprint sensor. | 11-12-2015 |
20160048298 | METHOD OF PROCESSING CONTENT AND ELECTRONIC DEVICE THEREOF - A method of operating an electronic device is provided. The method includes selecting at least one particular location in content displayed on a display, identifying text included in the at least one particular location, and executing at least one program based on the text. | 02-18-2016 |
