APPARATUS AND METHOD FOR ESTIMATING BIOMETRIC INFORMATION
First Claim
1. An apparatus configured to estimate biometric information, the apparatus comprising:
- a sensor configured to measure a light signal reflected from a subject and a temperature of the subject; and
a processor configured to perform temperature correction on the light signal reflected from the subject based on the temperature of the subject using a light signal-temperature relationship between the light signal reflected from the subject and the temperature of the subject to thereby obtain a temperature-corrected light signal, and estimate the biometric information of the subject based on the temperature-corrected light signal.

Abstract
An apparatus configured to estimate biometric information includes a sensor configured to measure a light signal reflected from a subject and a temperature of the subject, and a processor configured to perform temperature correction on the light signal reflected from the subject based on the temperature of the subject using a light signal-temperature relationship between the light signal reflected from the subject and the temperature of the subject to thereby obtain a temperature-corrected light signal, and estimate the biometric information of the subject based on the temperature-corrected light signal.

13. A method of estimating biometric information, the method comprising:
-
measuring a light signal reflected from a subject and a temperature of the subject; performing temperature correction on the light signal reflected from the subject based on the temperature of the subject using a light signal-temperature relationship between the light signal reflected from the subject and the temperature of the subject to thereby obtain a temperature-corrected light signal; and
estimating the biometric information of the subject based on the temperature-corrected light signal. - View Dependent Claims (14, 15, 16, 17)

18. An apparatus configured to estimate biometric information, the apparatus comprising:
-
a sensor configured to measure, at predetermined time intervals, a light signal reflected from a subject and a temperature of the subject in a reference state; and a processor configured to generate a light signal-temperature relationship between the light signal reflected from the subject and the temperature of the subject, by using the light signal reflected from the subject and the temperature of the subject as learning data to generate the light-signal temperature relationship. - View Dependent Claims (19, 20)
