no. 1 Embodiment approach
[0029] figure 1 It is a block diagram showing a schematic configuration of the measuring device according to the first embodiment. The measurement device according to the first embodiment acquires biological information from the measured pulse signal of the living body. It is assumed that a measurement device is attached to a part of a living body.
[0030] The measurement device according to the first embodiment includes a pulse signal processing unit 100 , a body motion signal processing unit 200 , a frequency domain analysis unit 300 , a time domain analysis unit 400 , and an output unit 501 .
[0031] Next, each part will be described.
[0032] The pulse signal processing unit 100 acquires a pulse signal of a living body from a sensor not shown. The pulse signal processing unit 100 includes a pulse signal acquisition unit 101 , a first direct current removal unit 102 , and a first noise removal unit 103 .
[0033] The body motion signal processing unit 200 acquires a s...
no. 2 Embodiment approach
[0091] Figure 12 It is a block diagram showing a schematic configuration of the measurement device of the second embodiment. The measurement device of the second embodiment has a new third signal processing unit 600 added to the measurement device of the first embodiment.
[0092] Next, the second embodiment will be described, and descriptions that overlap with the first embodiment will be omitted.
[0093] The third signal processing unit 600 performs correlation processing on a pulse signal (second pulse signal) different from the pulse signal (first pulse signal) processed by the pulse signal processing unit 100 .
[0094] The measuring device for measuring the first pulse signal may be different from or the same as the measuring device for measuring the second pulse signal. When the measurement apparatus is the same, the measurement method and the like are different, as long as the measurement signals are different. For example, when a reflective photoelectric pulse se...

Abstract
An object of the present invention is to suppress the throughput while maintaining the accuracy of the measuring device. A measurement device according to one aspect of the present invention includes: a first signal acquisition unit that acquires a pulse signal of a living body; a second signal acquisition unit that acquires a body motion signal of the living body; and a frequency analysis unit that combines the pulse signal and The body motion signals are respectively converted into frequency domains and frequency domain signals are respectively generated, and the frequency of the pulse of the living body is estimated from the frequency domain signals; and a time domain analysis section is calculated from the pulse signals and the frequency Biometric information for the organism.
Description
technical field [0001] Embodiments of the present invention relate to a measurement device, a measurement method, and a program. Background technique [0002] In recent years, wearable terminals are widely used to measure biological information due to increased health awareness. In particular, a wrist-watch type pulse measuring device using a reflective photoelectric pulse sensor has an advantage that measurement is relatively easy and does not cause discomfort to the user. [0003] The reflective photoelectric pulse sensor measures the pulse rate by using the reflected light of the light irradiated on the artery. Since hemoglobin in arteries has a property of absorbing light, reflected light fluctuates according to changes in the amount of hemoglobin due to changes in the volume of blood vessels during pulsation. The pulse rate is measured from the fluctuation of the reflected light. [0004] In addition, it is known that the measurement waveform of the reflective photoe...
