The optical member is arranged on the light emitting surface of the illumination part and transmits light emitted by the illumination part toward the object. The optical member includes a plurality of optical regions. The optical regions are arranged so as to surround a central region of the light emitting surface centered on an optical axis of the photographing part, and are configured to emit light having mutually different color characteristics toward the object.
