    • A biometric information detecting apparatus has a biometric sensor for measuring biometric information for a predetermined time period. An A/D conversion portion acquires a sampling data by subjecting an output of the biometric sensor to A/D conversion. A storing portion stores the sampling data. A frequency analyzing portion subjects the sampling data stored in the storing portion to a frequency analysis and stores a result of the frequency analysis to in storing portion. A biometric state value calculating portion calculates a biometric state value from the result of the frequency analysis stored in the storing portion. An SN ratio calculating portion calculates an SN ratio from the result of the frequency analysis stored in the storing portion. A determining portion determines a reliability of the biometric state value based on whether the calculated SN ratio exceeds a predetermined threshold. A measured data storing portion associates a result of the reliability determination with the biometric state value and stores the result of the reliability determination and the biometric state value.
    • 生物体信息检测装置具有用于在预定时间段内测量生物特征信息的生物特征传感器。 A / D转换部通过对生物传感器的输出进行A / D转换来获取采样数据。 存储部存储采样数据。 频率分析部分将存储在存储部分中的采样数据进行频率分析,并将频率分析的结果存储在存储部分中。 生物体状态值计算部根据存储在存储部中的频率分析的结果来计算生物体状态值。 SN比计算部分根据存储在存储部分中的频率分析的结果来计算SN比。 确定部分基于所计算的SN比是否超过预定阈值来确定生物特征状态值的可靠性。 测量数据存储部分将可靠性确定的结果与生物测定状态值相关联,并存储可靠性确定和生物测定状态值的结果。
