Benefits of technology

The invention is a display that creates a wide field of view 3D image for a viewer, with continuous motion parallax for a range of viewer positions in front of the billboard. The device uses a concave mirror and clear spots in a transparent sheet to efficiently generate the 3D image. The concave mirrors positioned near the front of the display focus the reflected light onto the viewer's eyes, allowing the image to appear in front of them. The short distance between the concave mirror and the image on the sheet reduces the need for specialized collimation, which helps to limit the angular dispersion of light rays. However, the pixel density in the display is limited by the concave mirror dimensions and the pinhole diameter.

Problems solved by technology

Since then, various methods have been used to display auto-multiscopic 3D images using source images on 2D surfaces, but they all suffer from drawbacks.

Embodiment Construction

[0040]In the following description, reference is made to the accompanying drawings, which form a part hereof and which illustrate several embodiments of the present invention. The drawings and the preferred embodiments of the invention are presented with the understanding that the present invention is susceptible of embodiments in many different forms and, therefore, other embodiments may be utilized and structural, and operational changes may be made, without departing from the scope of the present invention.

[0041]FIG. 1 and FIG. 11 illustrate a preferred embodiment of the billboard display system (200). FIG. 1 shows the embodiment in horizontal cross section across the billboard display system (200) confined to one of the indentations (110). This embodiment includes a light source (105), a sheet (115) of projection film with a grid-like array of images (405), and a concave mirror (135) combined together in a specific structural configuration.

[0042]The light source (105) is housed ...

Abstract

A billboard display system includes a light source housed in a box-like structure. The light source shines light away from a non-transparent front wall and through a transparent rear wall and thence through a sheet of projection film having an array of images thereon and thence is reflected by a corresponding array of concave mirrors back to corresponding apertures. The apertures are formed at the bottom of indentations, preferably cone-shaped throughout the area of the front wall. The light passes through the apertures and thence out of the indentations to create a 3D image in the eyes of a viewer looking at the front wall.

Description

TECHNICAL FIELD[0001]In the field of optical systems and elements, a three-dimensional billboard display system includes a film transparency sheet, lamp and concave mirror array specially adapted to project light from the display in a manner that renders different images to viewers in different locations in front of the display.BACKGROUND ART[0002]The term auto-multiscopic is used to define a display that allows multiple users to view three-dimensional scenes on a display, simultaneously and without the need for 3D glasses.[0003]Standard 3D integral photography was first proposed in 1908 by Gabriel Lippman, as a means of capturing 3D image information using 2D film surfaces. Since then, various methods have been used to display auto-multiscopic 3D images using source images on 2D surfaces, but they all suffer from drawbacks.SUMMARY OF INVENTION[0004]A billboard display system includes a light source housed in a box-like structure. A viewer, looking at the front wall of the box-like ...
