aumstereoscopic 3D projector using several 2D projectors, a projection screen, and two parallax barriers is proposed. Parallax barrier 1 facing the 2D projectors collimates the images that have aberrations on the edge of the projection screen. Parallax barrier 2 facing viewers acts as the parallax barrier in ordinary au-tostereoscopic 3D displays. The operation principle of the system, the calculation equations for the parallax barriers, and the capture and correction of parallax images are described in detail. A 60-inch autostereo-scopic 3D projector prototype having four 2D projectors was developed. The presentation of 3D static, ani-marion, and video images is realized by the prototype. The prototype's stereoscopic images without aberra-tions and with a little cross talk are sharp. Especially, its 3D resolution is the same as its 2D resolution.
