Claim Text:
1. A projection system comprising: a light source for applying a light beam having a predetermined wavelength; an imaging unit for capturing a subject to which the light beam having the predetermined wavelength is applied; a control unit for generating image data for projection based on the image captured by the imaging unit; a projecting unit for projecting, onto the subject, a projection image based on the image data for projection, wherein the imaging unit captures the projection image together with an image of a region responding to the light beam having the predetermined wavelength, and the control unit corrects the image data for projection to additionally display the projection image on a region which responds to the light beam having the predetermined wavelength and does not overlap a region onto which the projection image is projected, and corrects the image data for projection to erase the projection image in a region onto which the projection image is projected and does not overlap the region responding to the light beam having the predetermined wavelength.
