An electronic device and method are disclosed herein. The electronic device includes an image sensor, a radio frequency (RF) sensor, and a processor. The processor implements the method, including capturing an image including at least one object using an image sensor, determining an interest area of the at least one object included within the captured image, transmitting a radio frequency (RF) signal to at least a portion of the interest area using an RF sensor, receiving the transmitted RF signal reflected from the at least the portion of the interest area using the RF sensor, and obtaining biometric information for the at least one object based on the reflected RF signal.
