1. An apparatus for estimating bio-information, the apparatus comprising:
an optical sensor comprising a light emitter disposed on a substrate, and a plurality of light receiving groups which are arranged on a plurality of concentric circles on the substrate, at different distances from the light emitter in a radial direction, respectively; and
a processor configured to drive one of the plurality of light receiving groups that is selected based on a type of the bio-information to be estimated, and estimate the bio-information of an object based on optical signals detected by the driven light receiving group,
wherein a plurality of detectors included in each of the plurality of light receiving groups are spaced apart from each other by a predetermined angle on a corresponding one of the plurality of concentric circles, and
wherein each of the plurality of detectors in one of the plurality of light receiving groups does not align with any other detectors in the other plurality of light receiving groups, in the radial direction.
