PROBLEM TO BE SOLVED: To provide a system to prevent an operator from misunderstanding a systemic change as brain activity when the influence of the systemic change on a measurement signal is considered great.SOLUTION: The bioluminescence measuring instrument with an evaluation function determines the size of the influence of the systemic change on the measurement signal on the basis of a change in a heartbeat count obtained from pulse waves in the measurement signal obtained from a photodetection section and varies the display condition of a display section by the result of the determination.COPYRIGHT: (C)2010,JPO&INPIT【課題】計測信号に及ぼす全身性変化の影響が大きいと考えられる場合に、オペレータがそれを脳活動と誤って判断しないための仕組みを提供する。【解決手段】光検出部により得られた計測信号中の脈波から求めた心拍数変化などを元に、当該計測信号に及ぼす全身性変化の影響の大小を判定し、その判定結果により表示部の表示状態を変化させる。【選択図】図3
