Abstract: 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.

Abstract: 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.
