Abstract
A measuring apparatus as an aspect of the present invention includes: a first signal acquirer that acquires a pulse wave signal of a living body; a second signal acquirer that acquires a body motion signal of the living body; a frequency analyzer that converts the pulse wave signal and the body motion signal to a frequency domain to generate frequency domain signals, and estimates a frequency of a pulse wave of the living body on the basis of the frequency domain signals; and a time domain analyzer that calculates biological information about the living body on the basis of the frequency.
Claims10
A measuring apparatus comprising:
- a first signal acquirer that acquires a pulse wave signal of a living body;
- a second signal acquirer that acquires a body motion signal of the living body;
- a frequency domain analyzer that converts the pulse wave signal and the body motion signal to a frequency domain to generate frequency domain signals, and estimates a frequency of a pulse wave of the living body on the basis of the frequency domain signals;
- and
- a time domain analyzer that calculates biological information about the living body on the basis of the pulse wave signal and the frequency.
A measuring method in which a computer executes:
- acquiring a pulse wave signal of a living body;
- acquiring a body motion signal of the living body;
- converting the pulse wave signal and the body motion signal to a frequency domain to generate frequency domain signals, and estimating a frequency of a pulse wave of the living body on the basis of the frequency domain signals;
- and
- calculating biological information about the living body on the basis of the pulse wave signal and the frequency.
A non-transitory computer readable medium having a computer program stored therein which causes a computer when executed by the computer, to perform processes comprising:
- acquiring a pulse wave signal of a living body;
- acquiring a body motion signal of the living body;
- converting the pulse wave signal and the body motion signal to a frequency domain to generate frequency domain signals, and estimating a frequency of a pulse wave of the living body on the basis of the frequency domain signals;
- and
- calculating biological information about the living body on the basis of the pulse wave signal and the frequency.
