An electronic device is provided. The electronic device includes an earphone including a first impedance component, a signal generator configured to output a first alternating current (AC) signal, a first circuit including at least one first analog device having an impedance component electrically coupled to the first impedance component, and configured to receive the first AC signal and output a first detection signal including a voltage component corresponding to the first impedance component, and at least one processor configured to generate at least one piece of biometric information, based on the first detection signal, and output the at least one piece of biometric information.

Electronic device including earphone, and method of controlling the electronic device

Power consumption needed to illuminate a subject is reduced and the subject is continuously monitored. Each of a plurality of light sources emits light to the subject. An imaging circuitry obtains a captured image by imaging the subject. A controller performs light emission control to change a light source that emits light from among the plurality of light sources and causes the imaging circuitry to image the subject. A determiner determines whether a detection target that is pre-determined exists in an image area that is a part of the captured image obtained by the imaging circuitry and corresponds to the light source that emits light during imaging for obtaining the captured image.

Imaging device that continuously monitor a subject while reducing power consumption needed to illuminate the subject

Provided is a user identifying method using a bio-signal, the method including sensing a user input; detecting a bio-signal from the sensed user input; determining whether the detected bio-signal is valid, based on status information representing a status of a user at a moment when the user input is sensed; and identifying the user by comparing the bio-signal with at least one pre-stored reference bio-signal, according to a result of the comparing.

Method and device for identifying user using bio-signal

Provided is a method of measuring a heart rate in an electronic device. The method includes obtaining a face image of a subject by using the electronic device; determining a target region within the obtained face image; analyzing color information within the determined target region; and determining a heart rate of the subject on the basis of the analyzed color information. The analyzing of color information is performed on the basis of a differential arithmetic operation between a first color component and a second color component within the target region.
