PULSE MEASURING DEVICE, PULSE MEASURING METHOD, AND PULSE MEASURING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a pulse measuring device capable of accurately measuring a pulse rate even when noise is mixed in a pulse wave signal due to body motion of a subject to be measured.;SOLUTION: A pulse measuring device comprises: a pulse wave signal acquisition section for detecting a pulse wave by a pulse wave sensor 15 and acquires a pulse signal; a body motion signal acquisition section for detecting body motion by an acceleration sensor 33 and acquires a body motion signal; a frequency conversion section for converting both of the pulse wave signal and the body motion signal from a time area to a frequency area respectively and finds a pulse wave spectrum being a frequency spectrum of the pulse wave signal and an acceleration spectrum being a frequency spectrum of the body motion signal; a difference spectrum calculation section for finding a difference spectrum by calculating the difference between the pulse wave spectrum and the acceleration spectrum; and a pulse rate calculation section for finding a pulse rate on the basis of the difference spectrum.;COPYRIGHT: (C)2016,JPO&INPIT
