摘要

PROBLEM TO BE SOLVED: To provide a device capable of reducing influence of a body motion noise according to a detection position of a body motion when detecting a pulse wave from a moving subject, a method, a program and a recording medium.SOLUTION: A biological signal processing device 1 for processing a biological signal detected from a moving subject includes: pulse wave signal acquisition means 11 for acquiring a pulse wave signal; a body motion signal acquisition means 31 for acquiring a body motion signal; pulse wave frequency analysis means 55 for converting the pulse wave signal into a spectrum of a pulse wave in a frequency region; body motion frequency analysis means 66 for converting the body motion signal into a spectrum of a body motion in a frequency region; frequency conversion means 67 for acquiring a conversion spectrum obtained by converting the body motion spectrum into a spectrum in a desired frequency region according to a position in which the body motion is detected; and body motion component attenuation means 71 for attenuating a component corresponding to a frequency at a peak part of a frequency division spectrum of the body motion from the spectrum of the pulse wave.SELECTED DRAWING: Figure 1
