Abstract: A pulse wave is detected chronologically. Time-frequency analysis is performed on the detected pulse wave to determine a power spectrum for each time. Local maximum points are determined for each one of the power spectra determined for the respective times. For each one of the power spectra determined for the respective times, a certain number of largest values of the determined local maximum points are extracted as pulse rate candidates for that time. A pulse rate candidate is compared with a pulse rate candidate for the preceding time to determine a difference in frequency between them, and pulse rates for which the determined difference in frequency is equal to or greater than a preset reference value are eliminated from the candidates.
