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).
