More Information
Summary:The present invention relates to a method for correcting biometric signals in a continuous biometric information measurement system and, more specifically, to a method which, if a correction parameter is unstable when a correction factor is being calculated using a reference biometric value, does not use the current correction factor calculated from a reference biometric value as-is, but revises the current correction factor by applying, to the current correction factor, a compensation value calculated from the difference between the current correction factor and a previous correction factor, and thus even if a correction parameter is unstable it is possible to calculate a corrected biometric value by accurately correcting a biometric signal. The method also divides the entire usage time period of a sensor into multiple correction periods, and revises the correction factor in consideration of the degree of stabilization of the sensor depending on the correction period to which the time point at which the reference biometric value is input belongs, so as to accurately calculate the corrected biometric value from the biometric signal from the sensor.
