PROBLEM TO BE SOLVED: To solve a problem in which the accuracy of image analysis varies depending on the degree of light applied to a subject.SOLUTION: An illumination control system that controls one or more illumination devices includes lighting control unit that (i) turns on a first illumination device at least during a period in which an imaging element of the imaging device is not exposed, and (ii) turns off the first lighting device during a period in which the imaging element is exposed. The number of lighting times per unit time of the first lighting device may be n/m times the number of shutters of the imaging device per unit time or the number of frames of an image captured by the imaging device.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2019,JPO&INPIT【課題】 被写体に照射される光の具合によって、画像解析の精度が変動する。【解決手段】 １又は複数の照明装置を制御する照明制御システムにおいて、（ｉ）撮像装置の撮像素子が露光されていない期間の少なくとも一部において、第１照明装置を点灯させ、（ｉｉ）撮像素子が露光されている期間において、第１照明装置を消灯させる照明制御部を備える。第１照明装置の単位時間当たりの点灯回数は、単位時間当たりの撮像装置のシャッター回数又は撮像装置が撮像する画像のフレーム数のｎ／ｍ倍であってよい。【選択図】図６
