Abstract
A filter apparatus is a filter apparatus that transmits light emitted by a light source (a lighting apparatus), and the filter apparatus includes a simulated object that receives the light emitted by the light source, a driving device that mechanically moves the simulated object, and a first lens that transmits the light emitted by the light source and having passed through the simulated object. The filter apparatus projects, onto an illumination surface, a projection image of fluctuation of light and shadow formed by the light emitted by the light source and having passed through the simulated object and the first lens.
