PROBLEM TO BE SOLVED: To easily recognize and set a point to be irradiated by a spotlight, when it is in a dark state (extremely low luminance state) before lighting a light in the spotlight for a stage. SOLUTION: An image picked up by a noctovision camera (an infrared camera) 2 which is mounted on the same mount as a spotlight 1 in such a state as faced in the lighting direction of the spotlight 1 is displayed on a monitor 4. The image pickup range of the noctovision camera is irradiated by the light (infrared light) except a visible light by a noctovision light projector (an infrared projector). |
