An image is projected, without reducing in resolution, onto the full dome surface by the use of a single-eye fisheye lens. A video projector has a single-eye fisheye lens 7 for projecting a beam of light from an image display device onto the dome surface, a plurality of image display devices 11 and 21 jointly using the fisheye lens 7, and means 5 for combining the beams of light from the respective image display devices and sending the combination to the fisheye lens 7. Projection regions of images displayed on the respective image display devices correspond to sections A1 and A2 of the dome surface, and the projection regions to be projected onto the respective sections are combined to create a projection image continuing throughout the full dome surface.
