BIOLOGICAL INFORMATION MEASUREMENT APPARATUS AND PARAMETER SETTING METHOD THEREIN

摘要

PROBLEM TO BE SOLVED: To provide a biological information measurement apparatus, etc. in which the biological information of a person to be measured is measured optically and the parameters such as a gain to amplify the emission intensity of the light-emitting part and/or the output of the light-receiving part can be set appropriately.SOLUTION: A biological information measurement apparatus 1 comprises: a measurement part 50 having a light-emitting part 54 and a light-receiving part 56; an output signal output part 46 which amplifies a photoelectricity output and outputs it as an output signal; a pulse wave signal output part 40 which amplifies the AC component extracted from the output signal and outputs it as a pulse wave signal; a storage part 112 which stores the relationship of the required emission intensity to the output signal acquired in advance for a plurality of sample persons to be measured; and an emission intensity setting part 45 which causes the light-emitting part to emit light at a detectable emission intensity on a trial basis for a person to be measured and sets a required emission intensity to cause the light-emitting part to emit light such that the AC component exceeds the minimum amplitude extractable by the pulse wave signal output part, on the basis of the output signal acquired by the output signal output part and the relationship stored in the storage part.
