Apparatus and method for estimating bio-information

Abstract

Provided is an apparatus for non-invasively estimating bio-information by analyzing a pulse waveform. The apparatus for estimating bio-information according to an aspect of the present disclosure includes a processor configured to obtain a first characteristic point from a first pulse wave signal measured by a pulse wave sensor at a calibration time, obtain a second characteristic point from a second pulse wave signal measured by the pulse wave sensor at a bio-information estimation time, based on time information of the obtained first characteristic point, and estimate the bio-information of an object based on the obtained second characteristic point.

What is claimed is: 
     
         1 . An apparatus for estimating bio-information comprising:
 a processor configured to:   obtain a first characteristic point from a first pulse wave signal measured by a pulse wave sensor at a calibration time;   obtain a second characteristic point from a second pulse wave signal measured by the pulse wave sensor at a bio-information estimation time, based on time information of the obtained first characteristic point; and   estimate the bio-information of an object based on the obtained second characteristic point.
