Patent ID: 8724855

Claim:
A biometric information measurement apparatus using a user terminal, comprising: a light-emitting control unit configured to control at least one light emitting element which is configured to output an optical signal to a part of a body of a user; a camera which is to be placed in a position facing the part of the body, and configured to capture an image generated as a result of the optical signal passing through the part of the body or the optical signal being reflected off of the part of the body; an image analysis unit configured to analyze the image captured using the camera; and a biometric information measurement unit configured to measure biometric information about the user based on a result of the image analysis, wherein the biometric information measurement unit measures at least one of blood oxygen saturation, a pulse, and muscle activity information of the user, wherein the biometric information measurement unit measures the blood oxygen saturation from the image based on information about a hemoglobin density according to properties of light in a state in which the optical signal passed through blood vessels of the part of the body, wherein the biometric information measurement unit measures a degree of muscle activity using a variation in light transmittance attributable to swelling and reduction of muscle based on the image, and wherein the image analysis unit analyzes at least one selected from a brightness, a pattern, a light transmittance, and a variation in light transmittance of the captured image.
