脉动测量装置、光强度控制方法以及程序
摘要：
本公开涉及脉动测量装置、光强度控制方法以及程序。存在对能够在测量开始之后根据测量情况的变化执行光学校准的需要。LED21向主体照射光。光学检测器22输出光学检测信号。信号质量计算部分14计算基于光学检测信号生成的脉动信号的信号质量。身体运动级别确定部分15基于由加速度传感器检测到的加速度来确定主体是否保持静止状态。当确定主体保持静止状态时光强度确定部分16基于脉动信号的信号质量来确定LED 21的发光量。
摘要（英）：

The invention relates to a pulsation measuring apparatus, a light intensity control method, and a program. Requirement of executing optical correction according to measuring conditions after measurement begins exists. An LED 21 irradiates light to a subject. An optical detector 22 outputs an optical detection signal. A signal quality calculation portion 14 calculates signal quality of a pulsationsignal generated based on the optical detection signal. A body motion level determination portion 15 determines whether the subject maintains a quiescent state based on acceleration detected by an acceleration sensor. A light intensity determination portion 16 determines luminescence quantity of the LED 21 based on the signal quality of the pulsation signal when the subject is determined to maintain a quiescent state.
