An illumination system capable of varying the light emission intensity of illumination light while maintaining the color balance of the illumination light is provided. An additive process illumination system obtaining a specific color light by mixing a plurality of color lights, the illumination system includes: a plurality of light sources (11R, 11G, 11B) each emitting a different color light; a lighting period varying means (182) for varying the lighting period of each light source (11R, 11G, 11B); a light emission intensity varying means (181) for varying the light emission intensity of each light source (11R, 11G, 11B); and a control means for controlling the lighting period varying means (182) and the light emission intensity varying means (181) to control the light emission amount of each light source (liR, 11G, 11B). |
