Abstract
An apparatus for estimating bio-information includes: a sensor including one or more light sources configured to emit light to an object and a plurality of detectors configured to detect light reflected from the object; and a processor configured to transform a plurality of light quantities obtained from respective detectors of the plurality of detectors to a distance domain, to combine the plurality of transformed light quantities in the distance domain, to correct the combined light quantity based on a reference light quantity for correcting a deviation of a distance between the one or more light sources and the plurality of detectors, and to estimate bio-information based on a light quantity resulting from the correction.
