Zusammenfassung:	PROBLEM TO BE SOLVED: To enable even a person who is unfamiliar with light quantity adjustment of a luminaire to suitably perform light quantity adjusting operation by an interactive type adjustment guidance function of performing automatic or manual light quantity adjustment.SOLUTION: A predetermined area provided to a flat panel display and including an alignment mark is picked up by a camera while lit up by the luminaire. At this time, pattern luminance is calculated from image data on the picked-up predetermined area, and compared with a preset prescribed value to output a signal for adjusting lighting intensity. With the output signal, the quantity of illumination light of the luminaire is adjusted, and the calculated pattern luminance is displayed on a screen. Automatic or manual means is made selectable as means of adjusting the quantity of illumination light.
