Classification: CPC A | IPC A

Claim 11:
12. A method of estimating bio-information, the method comprising:
acquiring, by an image sensor, a first contact image of an object, based on the object being in contact with the image sensor;
determining, by a processor, a contact position and a direction of the object, based on the acquired first contact image;
controlling, by the processor, an actuator to adjust a position of the image sensor, based on the determined contact position and the determined direction of the object so that a field of view (FOV) of the image sensor moves to a predefined measurement area on the object;
acquiring a second contact image of the object based on the position of the image sensor being adjusted;
extracting a pulse wave signal based on a pixel intensity of the second contact image; and
estimating bio-information based on the pulse wave signal.
