Abstract

PURPOSE:To reduce the loss of the quantity of light incident on both eyes of an observer and prevent deviation of images by arranging photographs at opening angles of 45 deg. to surface mirrors on both sides of two surface mirrors joined at an opening angle of 90 deg. and shifting these two photographs and seeing them with an eyepiece part. CONSTITUTION:Photographs (or graphic patterns) 8 and 9 photographed from the same direction are shifted in parallel by position adjusting parts 10 and 11 and are adjusted in accordance with the parallax interval between both eyes of the observer and are presented to both eyes 5 of the observer through two surface mirrors 6 and 7 an eyepiece part 12. Thus, the parallax interval between both eyes is resolved, and the loss of the quantity of light incident on both eyes is reduced because surface mirrors are used instead of conventionally used prisms and mirrors, and deviation of pictures is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a three-dimensional image presentation device in the field of three-dimensional drawing technology.

Configuration and problems of conventional examples The three-dimensional image presentation devices that exist to date are based on the principle of the stereoscopic mirror announced by Whatston in England in 1838.
It is based on page 2.

Below, a conventional three-dimensional image presentation device in which a prism is arranged in a stereoscopic mirror announced by Wh6atStOn6 will be explained.

FIG. 1 shows a configuration diagram of a conventional stereoscopic image presentation device. In Fig. 1, 1 is a photograph (or figure) for the left eye taken in consideration of the binocular parallax interval, 2 is a photograph (or figure) for the right eye taken in the same way, 3 is a mirror, 4 is a prism, 6 is the position of both eyes of the observer.

A photograph (or figure) 1 for the right eye and a photograph (or figure) 2 for the left eye, taking into account the binocular parallax interval, are installed independently, and are observed through a mirror 3 and a prism 4 for each photo (or figure). By presenting the images to the left and right eyes of a person, the viewer can obtain a three-dimensional image.

However, with the above configuration, it is necessary to prepare two types of photographs (or figures), one for the right eye and one for the left eye, taking into account the binocular parallax interval, and for observation. Because the binocular parallax interval is different for each person, the photograph (or figure)
The problem is that there is a lack of versatility, that there is a large loss in the amount of light that enters both eyes because it uses two stages of light reflection: a mirror and a prism, and that the image often appears distorted due to the thickness of the mirror. It had a point.

Purpose of the Invention The present invention solves the above-mentioned conventional problems.
A three-dimensional image presentation device that can obtain three-dimensional images while satisfying the following conditions: providing versatility to the viewer's eyes, minimizing loss of light entering the observer's eyes, and preventing image shift. The purpose is to provide.

Structure of the Invention The present invention consists of two front mirrors joined at an aperture angle of 90 degrees, and two mirrors placed parallel to each other with an aperture angle of 46 degrees between the two front mirrors. A position adjustment unit that has a mechanism that allows you to shift the two photos (or figures) taken from the same direction while keeping them in the A row, and move each photo (or figure) between the right eye and the left eye. It is a three-dimensional image presentation device characterized by being equipped with an eyepiece that can be seen with the human eye, and by shifting two photographs (or figures) taken from the same direction while keeping them parallel using a position adjustment section. It solves the problem of binocular parallax distance and makes photography more versatile. By using surface mirrors instead of prisms and mirrors, the loss of light entering both eyes can be reduced. This has the effect of eliminating image shift.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a configuration diagram of a stereoscopic image presentation device in an embodiment of the present invention. .

In the same figure, 5 is the position of both eyes of the observer 6 and 7 are two surface mirrors joined with an aperture angle of 90 degrees, 8 and 9 are two surface mirrors that are sandwiched between each surface mirror and the aperture. Two photographs (or figures) taken from the same direction at a 46-degree angle and set parallel. 10 and 11 have a mechanism that allows the two photographs (or figures) to be shifted by 6 pages while remaining parallel. Position adjustment part, 12 is 2
This is an eyepiece that allows you to see each photo (or figure) with your right and left eyes.

The operation of the stereoscopic image presentation apparatus of this embodiment configured as described above will be described below.

Two photographs (or figures) 8 and 9 taken from the same direction are shifted using position adjustment units 10 and 11 in consideration of the binocular parallax interval of the observer, and the two front mirrors 6 and 7 are then It is presented to both eyes 5 of the observer through the eyepiece section 12.

As described above, according to this embodiment, two photographs (or figures) 8 and 9 taken from the same direction are
By using and 11 to shift the binocular parallax interval in consideration of the observer's binocular parallax interval, it is possible to eliminate the conventional binocular parallax interval and make the photograph (or figure) more versatile. Also,
By using a surface mirror instead of the conventionally used prism and mirror, the loss of the amount of light that enters both eyes can be reduced to a certain extent, and it has the effect of eliminating misalignment of images.

Page 6 Effects of the Invention The three-dimensional image display device of the present invention has two front mirrors joined at an aperture angle of 90 degrees, and two front mirrors sandwiched between the two front mirrors, and an aperture angle of 46 degrees with each front mirror. Two photos (or figures) placed in parallel and taken from the same direction, a position adjustment unit that has a mechanism that allows the two photos (or figures) to remain parallel without being separated, and each photo (or figure) By providing an eyepiece that allows the right and left eyes to view figures (figures), it is possible to solve problems caused by the conventional binocular parallax distance, and to reduce the loss of the amount of light entering both eyes. It has the advantage of being able to eliminate image distortion, etc., and its practical effects are great.
