Image projection display system for use in large field-of-view presentation
First Claim
1. An image projection display system (48) for use in large field-of-view presentation, which image projection display system (48) comprises a fold mirror arrangement (30) and a plurality of projection devices (64), characterised by the projection devices (64) having an apparent common projection point, and the image projection display system (48) being such that light beams from the projection devices (64) are optically combined by the fold mirror arrangement (30) so as to appear to be projected from essentially a common equivalent eye point (66) such that the displayed information of adjacent projected displays is correctly aligned with respect to a design eye point (56) without the need to apply distortion to the images.
