Abstract: In a method for measuring a biometric signal of a subject, the biometric signal is repeatedly detected using a biometric sensor and a noise intensity of noise contaminating the detected biometric signal is detected. Further, in the method, a signal intensity of the detected biometric signal is adjusted if the signal intensity meets an intensity change condition. If the detected noise intensity is greater than a noise threshold, adjustment of the signal intensity is withheld.

Abstract: In a pulse wave signal processor, a first filter attenuates a frequency component in an acquired pulse wave signal or in a differentiated pulse wave signal, and the attenuated frequency component is more than or equal to a first frequency. A second filter attenuates a frequency component in the acquired pulse wave signal, and the attenuated frequency component is less than the first frequency and more than or equal to a second frequency.

The partitioned sections are overlapped such that the characteristic points are coincident with each other, and arithmetically averaged.

Abstract: In a pulse wave analyzer, an ECG signal and a pulse wave signal are detected from an object to be analyzed. A plurality of feature points are extracting from the acquired ECG signal, the feature points appearing in a waveform of the ECG signal. The acquired pulse wave signal is segmented into a plurality of pulse wave signal pieces based on times at which the feature points appear. Each of the pulse wave signal pieces is segmented every heart beat. A reference pulse wave is calculated based on the plurality of pulse wave signal pieces, by multiplying the pulse wave signal pieces by coefficients and averaging the pulse wave signal pieces multiplied by the coefficients. The reference pulse wave is used to estimate the blood pressure of the object.

The first signal has a property different from the electrocardiographic complex. The second signal has a property different from the electrocardiographic complex and the first signal. The contact detection section detects a contact state of the subject to the first and second induction electrodes based on the signal difference.
