Abstract
A three-dimensional image display device is disclosed. In one embodiment, the device uses a curved transmissive screen and reflectors to minimize the space associated with the device when increasing the size of the three-dimensional image. By placing a physically driven background screen over the projected image and screen, excessively diffused reflection of the Fresnel lenses is eliminated. High-resolution real-time video images are provided as three-dimensional images by realizing three-dimensional images with enhanced perspective as if they are floating in space. According to one embodiment of the invention, a distortion of the three-dimensional image is minimized.
