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.COPYRIGHT: (C)2014,JPO&INPIT【課題】被測定者の生体情報を光学的に測定して、発光部の発光強度及び/又は受光部の出力を増幅するゲイン等のパラメータを適切に設定できる生体情報測定装置等を提供する。【解決手段】生体情報測定装置1は、発光部54と受光部56とを有する測定部50と、光電出力を増幅して出力信号として出力する出力信号出力部46と、出力信号から取り出されたAC成分を増幅して脈波信号として出力する脈波信号出力部40と、複数のサンプル被測定者に関して予め取得された必要発光強度-出力信号の関係を記憶する記憶部112と、被測定者に関して発光部を検出可能発光強度で試行的に発光させ、出力信号出力部で取得された出力信号と記憶部に記憶された関係とに基づいて、AC成分が脈波信号出力部で取り出し可能な最低限の振幅を超えるように、発光部を発光させる必要発光強度を設定する発光強度設定部45と、を備える。【選択図】図10
