Title: 3D image convertible projection optical system

Abstract: A 3D image convertible projection system for viewing an image broadcasted as a 3D image or an image from a 3D DVD, etc., using a general projector in which a general projector receives a left-eye image and a right-eye image for the 3D image in one frame and projects them toward a projection lens. The 3D image projection system is configured so that the left-eye image and the right-eye image having a 2D form, which are projected from a general projector, are magnified so that a vertical magnification rate is 0 and a horizontal magnification rate is 1.5-2.5 times and at the same time divides the images into leftward and rightward directions. The optical system includes a first and second curved surface mirrors or a left and right symmetric eccentric curved surface lens, and a second set of mirrors for reflecting and magnifying the images to be projected toward a screen.
