ABSTRACT:
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.
