摘要

A frequency analyzer carries out a frequency analysis on a pulse wave signal output from a pulse wave detector. A candidate extractor extracts candidate spectrum peaks from a frequency analysis result of the frequency analyzer. A phase variation calculator calculates variations in phase angle of each of the extracted candidate spectrum peaks, and a spectrum peak selector selects a target spectrum peak from among the extracted candidate spectrum peaks based on their respective variations in phase angle. A pulse rate is calculated using the target spectrum peak.
