Measurement device and measurement method

Abstract

A measurement device includes a biosensor having a light-receiving part to receive measuring light from a region to be tested and configured to obtain a biometric output based on the measuring light, and a controller configured to determine whether or not to perform measurement of biological information based on the biometric output and a predetermined threshold. A measurement method includes obtaining a biometric output by a biosensor, and determining, by a controller, whether or not to perform measurement of biological information based on the biometric output and a predetermined threshold.
