Abstract
An illumination system includes: a light irradiation unit that projects light toward a predetermined illumination area; an image acquisition unit that acquires an image of the illumination area; an object detecting unit that detects a shading object based on image information of the illumination area, acquired by the image acquisition unit; an information generating unit that generates the control information for setting each of the plurality of reflecting mirrors to an on state or an off state such that a plurality of irradiation patterns are alternately irradiated, each of the plurality of irradiation patterns having different arrangement of the dark pixels and the light pixels from each other; and an irradiation control unit that controls the light irradiation unit based on the generated control information.
