A light source for verification (24) is lit, and an image at that time is photographed with a camera (21). A near-infrared light with a wavelength of 810nm is projected from the light source for verification (24), approximating the wavelength of fluorescent light which is emitted from indocyanine green. When the camera (21) is operating normally, an image of a region in which the near-infrared light is projected is photographed by the camera (21), and the image thereof is displayed in a display unit (14). It is thus possible to easily execute an operation verification of the camera (21). |
