Abstract
A projection system includes a light source device, an imaging unit, and a projector. The light source device includes a projection surface including a reference area, and emits light including non-visible light and visible light from the reference area. The imaging unit receives non-visible light and captures an image of the projection surface. The projector projects a projection image of visible light on the projection surface based on the captured image captured by the imaging unit.
