<p><P>PROBLEM TO BE SOLVED: To reduce delay of a calculated pulse rate when applying moving average processing to calculation of the pulse rate. <P>SOLUTION: A pulsation detector 100 includes: a pulsation detection unit 60 for detecting pulsation signals originating from pulsation of a subject; a pulse value calculation unit 90 for calculating a pulse value for every prescribed time on the basis of the pulsation signals; a memory unit 70 for storing the calculated pulse value; and a weighted moving average calculation unit 72 for executing weighting processing to m pieces of pulse values from a first pulse value as the latest pulse value to an m-th (m is an integer of≥3) pulse value as the oldest pulse value which are outputted from the memory unit 70, and then calculating a moving average value using the pulse values after the weighting processing. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
