PROBLEM TO BE SOLVED: To provide an illumination system and a brightness detection sensor capable of automatically performing matching between an illumination instrument and a brightness sensor.SOLUTION: A brightness sensor control unit 12b refers to a matching table 11a to instruct an illumination instrument control unit 12a to change, for each group, a light-emission amount of each illumination instrument 2 included in the group by a predetermined amount. The illumination instrument control unit 12a, according to the instruction from the brightness sensor control unit 12b, changes each illumination instrument 2's light-emission amount by the predetermined amount. The brightness sensor control unit 12b associates an illumination instrument 2 whose light-emission amount has been changed by the predetermined amount by the illumination instrument control unit 12a, with a brightness sensor 3 corresponding to a maximum variation obtained by comparing variations in brightness detected by respective brightness sensors 3 in a group in which the illumination instrument 2 is included.SELECTED DRAWING: Figure 2 |
