Claim 0:
1. An apparatus for estimating bio-information, the apparatus comprising:
an image sensor configured to acquire a first contact image of an object, based on the object being in contact with the image sensor;
an actuator; and
a processor configured to:
determine a contact position and a direction of the object, based on the acquired first contact image;
control the 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;
control the image sensor to acquire a second contact image of the object, based on the position of the image sensor being adjusted,
extract a pulse wave signal based on a pixel intensity of the second contact image; and
estimate the bio-information based on the pulse wave signal.
