Claim 13:
14. A method of estimating bio-information of a user, the method comprising:
obtaining a fingerprint image of a finger of the user by a sensor, wherein the sensor comprises: one or more light sources configured to emit light onto the finger; and, one or more complementary metal-oxide semiconductor (CMOS) image sensors;
measuring a force or a pressure applied by the finger;
obtaining a first feature value related to pulse waves based on the fingerprint image;
obtaining a second feature value related to skin elasticity based on the fingerprint image;
obtaining a third feature value based on the force or the pressure; and
estimating the bio-information based on the first feature value, the second feature value, and the third feature value.
