A first light source emits near-infrared radiation with a wavelength near 810 nm, which is excitation radiation for exciting indocyanine green, a second light source emits a violet light with a wavelength of 410 nm that is excitation radiation for exciting PpIX, and a third light source emits white light. An imaging portion comprises a first imaging element able to capture visible light, a second imaging element able to capture red light that is emitted by the PpIX, and a third imaging element able to capture near-infrared light emitted by the indocyanine green.
