Abstract: An electronic device is provided. The electronic includes a camera module and a processor configured to capture at least one image of an object using the camera module, obtain a sound using a microphone operably connected to the processor when the at least one image is captured, determine whether the sound is related to the object, when the sound is determined to be unrelated to the object, change at least one attribute of the sound and store the changed at least one attribute of the sound.

Abstract: Disclosed is an audio output control method and an electronic device supporting the same. The audio output control method includes determining an output of an audio processing unit decoding an audio source signal, and controlling generating of a reference signal to be supplied to an audio output unit in response to an output of the audio processing unit.

Abstract: A method of reducing noise is provided. The method includes determining whether an audio output of the audio source has interference based on a sampling frequency and an operating frequency of at least one device element e, and maintaining or changing the operating frequency of the at least one device element depending on whether interference is determined.

Abstract: An apparatus and method for setting a modulation frequency within a non-use frequency range so as to reduce ElectroMagnetic Interference (EMI) occurring during frequency modulation in a portable terminal are provided. The apparatus includes a controller and a frequency set unit. At frequency modulation, the controller determines whether a modulation frequency corresponds to a frequency inducing EMI. In a case where it is determined that the modulation frequency corresponds to the frequency inducing EMI, the frequency set unit resets the modulation frequency.

Abstract: A portable terminal and a method for detecting an earphone connection are provided. The method includes detecting a connection of earphones; detecting and analyzing a sound input through the connected earphones; and determining whether a microphone is installed in the earphones by comparing an analysis result with a first predetermined threshold.
