摘要

an interface for placing a biological body to be imaged; a light source for emitting infrared light; an imaging unit for imaging a blood vessel image of the biological body by the light from the light source; and an image operation unit for processing the blood vessel image captured by the imaging unit. The interface has an opening toward the imaging direction of the imaging unit. The light source has a light shield for applying infrared light to the biological body from the imaging side of the biological body and shielding the infrared light emitted from the light source not to be directed to the imaging direction.
