Abstract
It is possible to reduce power consumption of a pulsimeter while suppressing a degradation in an accuracy of measuring pulse. A pulsimeterincludes a light emitter, a photodetector, an AD converter, a frequency analyzing unit, and an adjusting unit. The light emitteremits light to a blood vessel of a measurement target. The photodetectordetects light emitted by the light emittervia the blood vessel. The AD converteranalog/digital converts an output signal of the photodetector. The frequency analyzing unitfrequency-analyzes data converted by the AD converter. The adjusting unitadjusts an amount of light emitted by the light emitterbased on the analysis result by the frequency analyzing unit
