Benefits of technology

[0011]An object of the present invention aims elimination of the above-mentioned disadvantages by providing a virtual image device generating 3D images in the eyes of the observer using conventional displays, based, for example, on conventional DLP or LCOS microdisplay technologies, or the screens with projected images of the related microdisplays. Furthermore, liquid crystal (LCD), plasma (PD) or organic LED (OLED) displays can be used for 3D image generation.

Problems solved by technology

However, the viewing angle range is very narrow in this approach making it so far less suitable for major applications.
While suited for their intended purpose, a disadvantage of devices of this type is that the display must move at a high rotation or one-directional motion speed.
Furthermore the most common rotary 3D displays require complex and highly precise mechanics and the related precisely synchronized display imaging schemes.

Embodiment Construction

[0027]The virtual 3D image production device is shown in FIGS. 1-7 for purposes of illustration. In FIG. 1 we show an eye appearance of a three-dimensional object in a prior art device generating virtual images. A high-quality virtual image hardly distinguishable from the original real object may be generated.

[0028]FIG. 2 shows a schematic cross-section of the prior art device. A virtual image of the object is originating in the observer's eye as illustrated in FIG. 1 due to a system composed of: a real object; a lamp; and a curved mirror. The light from the real object illuminated by a lamp is reflected by a curved mirror through a window and a virtual image is formed for the observer's eyes. The observer is looking at the window form outside, as depicted in FIG. 1.

[0029]A device similar to shown in FIG. 2 where the real object is replaced by a two-dimensional display is shown in FIG. 3. The display moves in between of two or more positions. The image on the display is changed when...

Abstract

A device for generation of three-dimensional images in the observer's eye using at least one two-dimensional display and an optical system with an adjustable focal length. The display generates planar images corresponding to the different depths of the designed three dimensional (3D) image and the images are then directed to at least one mirror or lens with the adjustable focal length synchronized to the particular image. The optical system generates virtual images at different virtual planes in such a way that the eye receives a complete 3D virtual image.

Description

[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 337,263, filed Feb. 2, 2010BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a device generating virtual three dimensional (3D) images, preferably moving images, formed from planar two-dimensional (2D) images. More specifically the present invention relates to a device for generation of virtual 3D moving images such as 3D video or motion pictures.[0004]2. Description of Related Art[0005]There is a need in generation of three-dimensional moving images. Possible applications include 3D: cinema; TV displays, out-of-door advertisement boards; computer monitors for training and education; mobile phone projectors, head-up-displays, interactive displays, “touch screen” displays and other. There are different approaches for generation of 3D images.[0006]Some of the approaches are based on the delivery of two different images generated on a surface of a special scre...
