Abstract: A blood vessel detection device comprises: a first irradiation unit for irradiating a predetermined site of a subject with light of a first wavelength that is absorbed less by hemoglobin or water and light of a second wavelength that is absorbed more by hemoglobin or water than the first wavelength; a second irradiation unit for irradiating the predetermined site with light of a third wavelength that is absorbed less by hemoglobin; a light intensity detection unit for detecting the intensity of light emitted from the subject at one or more positions spaced apart by a predetermined distance from the light irradiation positions of the first and second irradiation units or one or more contiguous positions; and a control unit that calculates blood vessel depth information, calculates blood vessel angle information, and determines an optimal position for measurement based on the blood vessel depth information and the blood vessel angle information.

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.
