Two light splitters 30, and a concave mirror 32.

Here, the first and second projectors disposed inside the housing are basic projectors for generating stereoscopic images, which are the same as those of conventional projectors, and are basically devices capable of obtaining duplicate images, that is, computer monitors, slide projectors, and film projectors. In addition to laser projectors, LCDs, general monitors and photographs, real-life illuminated objects are also possible.

In addition, the light splitter used is a reflectance capable of giving an appropriate three-dimensional effect, and the surface thereof is suitably coated so that the reflectance is preferably adjusted to 50%.

In addition, the three-dimensional stereoscopic image generating apparatus 200 further includes a one-way mirror and a Fresnel lens 34 installed on the light exit portion of the housing 22. Since the one-way mirror and the Fresnel lens are joined together, the same reference numeral 34 is shown to simplify the description of the drawing, and the one-way mirror 34 is a three-dimensional stereoscopic image generating apparatus 200 viewed by an external viewer. When viewing a three-dimensional image formed in the light emitting portion of the housing 22 from the front of the) serves to make the inside of the apparatus not visible. To this end, the one-way mirror may comprise a number of coating materials provided on the glass to perform this function.

The Fresnel lens 34 adjusts the position of formation of the stereoscopic image. It can be adjusted to zoom in or out. At this time, the magnification of the 3D stereoscopic image seen by the external viewer is mainly determined by the focal length of the concave mirror 32 and the Fresnel lens 34, and can be appropriately adjusted according to indoor or outdoor.

Now, the process of how the images projected by the projectors of FIG. 2 described above form three-dimensional stereoscopic images with each other is shown separately in FIGS. 3A and 3B.

Hereinafter, referring to FIGS. 2, 3A, and 3B, how light from the first stereoscopic projector 24 and the second stereoscopic projector 26 form a synthesized stereoscopic image will be described.

First, FIG. 3A is a schematic diagram illustrating an optical path for generating a stereoscopic image projected by the first stereoscopic projector shown in FIG. 2. In FIG. 3A, the first stereoscopic image projected by the first stereoscopic projector is illustrated by the right arrow 25 (→). The first stereoscopic image 25 is first transmitted through the first splitter 28 and then partially transmitted, partially reflected and reflected by the second splitter 30 to the concave mirror 32. Heading, and after being totally reflected by the concave mirror 32, passes through the second light splitter 30 again to produce a first stereoscopic image on the space to the right of the light exit of the housing 22, in which the up arrow 25 Illustrated by ') (↑).

3B is a schematic diagram showing an optical path for generating a stereoscopic image projected by the second stereoscopic projector shown in FIG. 2. In Fig. 3B, the symbol 27 in which the second stereoscopic image projected by the second stereoscopic projector is directed upward ( Is illustrated. The second stereoscopic image 27 is first reflected by the first optical splitter 28, and then partially transmitted and partially reflected by the second optical splitter 30, and then directed to the concave mirror 32. Is completely reflected by the concave mirror 32, passes through the second light splitter 30 again, and forms a second stereoscopic image on the right space of the light exit portion of the housing 22. In FIG. ') ( Is illustrated.

In the present apparatus, two stereoscopic projectors are provided so that each stereoscopic projector can project stereoscopic images of different subjects or contents so that stereoscopic images of different subjects or contents are effectively stereoscopically contrasted or highlighted. Thus, the first stereoscopic projector 24 projects the first stereoscopic image, and the second stereoscopic projector 26 projects the second stereoscopic image, wherein the stereoscopic images projected from each stereoscopic projector are stereoscopic images of independent subjects or contents, For example, it may be an image of an independent character of a projector or a fighting game machine. For example, the independent heroes of a martial art game can be contrasted or highlighted with the same degree of stereoscopic images so that the fighting scenes of the two heroes can be realistically or three-dimensionally expressed. Since these two heroes are independent stereoscopic images projected by each stereoscopic projector, they can be represented on the screen (space on the right side of the light emitting part) by operating each stereoscopic projector separately.

Therefore, the first stereoscopic image 25 'and the second stereoscopic image 27' are images projected by the first stereoscopic projector and the second stereoscopic projector and represent mutually independent subjects or contents, and these images 25 ', 27 ') Is three-dimensionally synthesized on the right space of the light exit portion of the housing 22 to make two independent subjects or contents contrast or stand out. In addition, it is possible to display the spatial recognition of these images more effectively and realistically by virtue of the left and right positions on the screen where the images 25 'and 27' are generated when viewed by the viewer, and the far and near distances from the viewer.

The 3D stereoscopic image generating apparatus 200 may be applied to, for example, a projector, a single player or a double player. In some cases, as shown in Figure 5 can also be applied to the multi-player game machine according to the principle of the present invention.

When the three-dimensional stereoscopic image generating apparatus 200 is used as a projector, two-dimensional projectors can be pre-programmed, for example, or stereoscopically projected through each stereoscopic projector by electronically controlling each stereoscopic projector by connecting to a control computer. At the same time, a plurality of viewers can simultaneously watch, for example, three-dimensional images in which two independent hero's fighting images or pia are contrasted and active on the screen (the right space of the light exit portion of the housing 22).

In addition, when the three-dimensional stereoscopic image generating apparatus 200 is used as a single game machine, one stereoscopic projector provides stereoscopic images by a control computer, and the other stereoscopic projector allows the viewer to directly control the two main characters. You can enjoy a fighting scene or an activity scene of the game, and if it is used as a two-player game machine, the two viewers control the stereoscopic projectors respectively to adjust or control the fighting scene or the activity scene of each main character by the operation of the two viewers. You can also enjoy the game with realism. If a multiplayer game machine is used, the number of stereoscopic projectors may be increased by using the above method as shown in FIG. 5.

As described above, the three-dimensional stereoscopic image generating apparatus of the present invention, which independently projects two stereoscopic images through two stereoscopic projectors, not only provides better stereoscopic effect by contrasting two independent stereoscopic images, but also provides two different stereoscopic images. By showing the theme or activity of the two protagonists at the same time, the viewer can highlight the enhanced three-dimensional effect applicable to more fields such as projectors and game consoles, and provide unique and advantageous advantages. In addition, according to the principles of the present invention, by increasing the number of stereoscopic projectors, images of various subjects or contents can be viewed in an improved stereoscopic sense. This is because one stereoscopic projector can represent one subject or content independently of each other.
