Apparatus for estimating bio-information, and method of determining false detection of bio-signal peaks

An electronic device comprising:

• a main body;
• and
• an apparatus configured to estimate bio-information and disposed in the main body,
• wherein the apparatus for estimating bio-information comprises:
• a sensor configured to acquire a bio-signal from an object of a user, by transmitting ultrasonic waves to the object and receiving reflection waves reflected from the object;
• and
• a processor configured to detect peaks from the bio-signal, configured to determine false detection of a peak, among the detected peaks, by using at least one of a time interval between a current peak and an immediately preceding peak, amplitudes of the current peak and the immediately preceding peak, shapes of waveforms on a left region and a right region of the peak, and an occurrence position of the peak, and configured to determine a health condition of the user based on a result of determining the false detection of the peak.
