An autostereoscopic three-dimensional projector includes a MicroElectroMechanical System (MEMS) processor, a virtual movable lens array, and a projection lens, the MEMS processor transfers each view image of the multiview image to a virtual movable lens array with different angles, the virtual movable lens array projects each of multiview images that are input with different angles to different locations of the projection lens, and the projection lens outputs the multiview image to a screen.
