摘要:
A pulse wave measurement apparatus includes a light emitting device that applies light to a measurement position at which a pulse wave is measured, and a plurality of light receiving devices that output measurement signals based on the amount of received light which is applied from the light emitting device and is reflected from the measurement position. The control unit of the pulse wave measurement apparatus performs the independent component analysis on the measurement signals output from the plurality of light receiving devices, and calculates the weighting factors of each component when each of the measurement signals is divided into a plurality of components. The control unit calculates the dispersion of the calculated weighting factors for each component, and specifies a component in which the calculated dispersion is the smallest. The control unit generates pulse wave information indicative of the pulse wave based on the specified component.
