Abstract
An apparatus for estimating blood pressure, includes a pulse wave sensor configured to measure a first pulse wave signal from a user, and a processor configured to differentiate or integrate the measured first pulse wave signal to obtain a reference signal, correct the measured first pulse wave signal, based on the obtained reference signal, to obtain a second pulse wave signal, and estimate the blood pressure, based on the obtained second pulse wave signal.
