Pulse measurement device, pulse measurement method and non-transitory computer readable medium

A pule measurement method comprising:

• acquiring pulse wave detection signals from a pulse sensor configured to detect pulse waves of a subject;
• generating a pulse wave frequency signal by converting the pulse wave detection signals into a frequency domain signal from time domain signals;
• acquiring acceleration detection signals indicating acceleration of the subject
• determining a body motion level of the subject based on the acceleration detection signals;
• searching for a peak of a spectrum in the pulse wave frequency signal within a searching range varying based on the body motion level;
• and
• generating pulse information based on a frequency position of the peak detected by searching for the peak.

a non-transitory computer readable medium storing a program which causes a processor to execute steps of:

• acquiring pulse wave detection signals from a pulse sensor configured to detect pulse waves of a subject;
• generating a pulse wave frequency signal by converting the pulse wave detection signals into a frequency domain signal from time domain signals;
• acquiring acceleration detection signals indicating acceleration of the subject
• determining a body motion level of the subject based on the acceleration detection signals;
• searching for a peak of a spectrum in the pulse wave frequency signal within a searching range varying based on the body motion level;
• and
• generating pulse information based on a frequency position of the peak detected by searching for the peak.
