Abstract
An apparatus for measuring a concentration of hemoglobin includes a light application device for applying light to a detection region containing a blood vessel present in a living body; an image capturing device for capturing an image of the detection region to which the light is applied; and an analyzer for analyzing the concentration of hemoglobin in blood flowing through the blood vessel by processing the captured image. The analyzer includes a light intensity detector for detecting a light intensity of a body tissue and a light intensity of blood using the captured image. It further includes a calculator for calculating the concentration of hemoglobin from a ratio of the light intensity of the body tissue relative to the light intensity of blood thus detected.
