Abstract
An electronic device may include an optical sensor configured to emit a reference light to a reference object and detect the reference light reflected from the reference object during calibration, and emit a measurement light to a target object and detect the measurement light reflected from the target object during a measurement; and a processor configured to perform the calibration of the optical sensor while the electronic device is disposed to oppose or in contact with the reference object by controlling the optical sensor to emit and detect the reference light, and estimate bio-information based on a light quantity of the measurement light that is reflected from the target object by the optical sensor, and a light quantity of the reference light reflected from the reference object.
