Abstract: PURPOSE: An apparatus for generating three-dimensional image is provided to reduce the distortion of images by reducing the number of utilized reflecting mirror and expand the size of the three-dimensional image by positioning a projector outside the housing. CONSTITUTION: An image projected by a projector(2) is reflected on a semi-transparent screen(6) by a reflection mirror(4), wherein the image reflected on the screen is symmetrical with the image of the projector, so that the image is converted in the left and right directions. The image projected on the screen is a real image and light is emitted from the real image. Some of the light is reflected on an optical divider(8) toward a concave mirror(10) and some of the light is projected through the optical divider. The concave mirror forms a three-dimensional image at a right space in a light emitting part of the housing. A reflector is positioned on the passage of the projector and the semi-transparent screen to prevent the conversion of the left and right direction of the image.
