1. An apparatus for estimating bio-information of a user, the apparatus comprising:
a first sensor configured to obtain a fingerprint image of a finger of the user, wherein the first 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;
a second sensor configured to measure a force or a pressure applied by the finger; and
a processor configured to:
obtain, based on the fingerprint image, a first feature value related to pulse waves and a second feature value related to skin elasticity;
obtain a third feature value based on the force or the pressure; and
estimate the bio-information of the user based on the first feature value, the second feature value, and the third feature value.
