Pulse rate monitor

摘要

The pulse rate monitor is arranged by employing pulse wave component extracting means for extracting pulse wave components from frequency-analyzing results of a pulse wave sensor (301) which senses the pulse of a body and an action noise sensor (302) which senses movement of the body and pulse rate calculating means for calculating a pulse rate per 1 minute from the pulse wave components extracted from data from the pulse wave (301) and action noise sensor (302) by the pulse wave component extracting means, so that the pulse rate is displayed (313). Furthermore, there is employed an action noise signal confirming means (304,307) for judging whether or not an action noise is present, and also calculation changing means for changing a calculation method of the pulse rate based on the output signal from the action noise signal confirming means. As a result, the amount of calculation is reduced and power consumption is suppressed, so that calculation time can be shortened.
