Abstract
It is possible to reduce power consumption of a pulsimeter while suppressing a degradation in an accuracy of measuring pulse. A pulsimeter 1 includes a light emitter 10, a photodetector 12, an AD converter 14, a frequency analyzing unit 15, and an adjusting unit 17. The light emitter 10 emits light to a blood vessel of a measurement target. The photodetector 12 detects light emitted by the light emitter 10 via the blood vessel. The AD converter 14 analog/digital converts an output signal of the photodetector 12. The frequency analyzing unit 15 frequency-analyzes data converted by the AD converter 14. The adjusting unit 17 adjusts an amount of light emitted by the light emitter 10 based on the analysis result by the frequency analyzing unit 15.
