PROBLEM TO BE SOLVED: To improve accuracy in measuring a pulse or pulse wave.SOLUTION: From a first band signal which includes the component of a first frequency band of a first measurement signal acquired by applying light of a prescribed frequency onto an area that includes the pulse, a bodily movement signal extraction unit extracts a bodily movement signal that comprises a component generated by bodily motion. A calculation unit generates a pulse wave signal, which is the difference signal between the bodily movement signal and a second band signal which includes the component of a second frequency band of the first measurement signal. This technique can be applied, for example, to a device for measuring a pulse or pulse wave.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】脈波や脈拍の計測精度を向上させる。【解決手段】体動信号抽出部は、所定の波長の光を脈を含む部分に照射することにより取得された第1の計測信号の第1の周波数帯域の成分を含む第1の帯域信号から、体動により生じる成分を含む体動信号を抽出する。演算部は、第1の計測信号の第2の周波数帯域の成分を含む第2の帯域信号と体動信号との差分信号である脈波信号を生成する。本技術は、例えば、脈波や脈拍を計測する装置に適用することができる。【選択図】図6
