(57) [Abstract] [Purpose] A pulse rate measuring apparatus for measuring a pulse rate based on a plurality of types of pulse wave signals output from a tonometer sensor having a single array composed of a plurality of pressure-sensitive sensor elements. In, increase the measurement accuracy. A weighted average signal of the plurality of types of pulse wave signals that accurately reflects motion artifacts is subtracted from each pulse wave signal to obtain a corrected pulse wave signal from which motion artifacts are substantially removed. And by calculating the pulse rate from this corrected pulse wave signal, Artifacts such as motion artifacts are preferably compensated to obtain high pulse rate reliability. |
