Summary:PROBLEM TO BE SOLVED: To provide an illumination control device capable of accurately controlling an illumination apparatus even if an image photographed by an imaging device with an automatic sensitivity control function is used.SOLUTION: An illumination apparatus is controlled by a plurality of light intensities set in advance, sample data is prepared from brightness of an image in a region including a steady luminous intensity light source in images photographed at this time and the plurality of light intensities controlling the illumination apparatus, and the illumination apparatus is controlled by using this sample data. Thereby, even if an imaging device with an automatic sensitivity control function is used, the illumination apparatus can be accurately controlled from brightness of the images photographed by the imaging device, in a short time.
