Field: Measurement (Instruments)
Classification: CPC A  G | IPC G

Claim 14:
15. A method of estimating bio-information by using an electronic device comprising an optical sensor, the method comprising:
performing calibration of the optical sensor by emitting a reference light to a reference object disposed on a charger and detecting the reference light reflected from the reference object during calibration which occurs while a battery of the electronic device is being charged;
after a battery charging state of the electronic device, guiding a user to follow measurement phases by outputting an output signal that comprises either one or both of a vibration signal or a sound signal;
measuring a light quantity of a measurement light that is emitted to and reflected from a target object; and
estimating the bio-information based on the light quantity of the measurement light and a light quantity of the reference light reflected from the reference object.
