Description

3-D Stereoscopic Imaging Game Display System

The present invention relates to a three-dimensional stereoscopic video game display system, and in particular, a part of the image of the game can be physically separated from the background screen to give a three-dimensional three-dimensional effect to create a more lively game, preferably external light Provided is a system for preventing generation of ghost images.

In general, a game screen may be divided into a background image and a foreground image. In the conventional electronic entertainment game, a game character or a game unit selected by a gamer appears in the projection image as a projection image. The game character or game unit is moved by the gamer operating a joy stick or a function button. Physically, conventional games display game characters (or game units) together on a two-dimensional flat screen, but are visually applied to give gamers more visibility by allowing the game characters in the projection image to appear in the background image. You will feel close.

From a technical point of view, the game that exhibits the most excellent three-dimensional effect in the past is a game based on virtual reality technology. Virtual reality games are mainly enjoyed by wearing a separate device called a head mount using a polarized lens, so the problem of using a separate device and playing a game for a long time can cause tears or dizziness. I have a problem. In addition, in order to watch the game of the gamer from the side or the back there is a problem that the viewer must also wear a head mounter like the gamer. For cost reasons or technical reasons, current virtual reality-based entertainment equipment does not provide multiple head mounters in one. Thus, other gamers cannot enjoy playing a game in three dimensions.

Another method is a hologram technique, but since a laser is used and projection onto a medium such as a glass substrate, there is a limit in expressing a three-dimensional effect.

Accordingly, an object of the present invention is to solve the problems of the prior art and to solve the technical problems that have been requested from the past. Specifically, in order to provide a more realistic and three-dimensional game image, a separate device such as a head mounter by physically separating the game character or game unit corresponding to the projection image from the background image and projecting it in the air in front of the flat screen It is an object of the present invention to provide a device for synchronizing a projection image and a background image, in which not only a gamer but also other viewers can enjoy it at the same time. In addition, another object of the present invention is to provide a system that provides a clearer game image by eliminating generation of ghost images by external light, which is a problem in the conventional video system.

4 is a comparison of a display example of the prior art by perspective and an example display by the three-dimensional projection of the present invention;

5 is a top view of an example of a game projected by a system according to one embodiment of the present invention;

6A through 6D and 7A through 7D are diagrams illustrating a configuration of a system according to an exemplary embodiment in which no ghost image is generated by external light and an extinction step of external light.

In order to achieve this object, the three-dimensional stereoscopic game display system of the present invention,

(1) a projection image source providing a projection image of a game character or game unit in which focus is formed at a position protruding from the system by partial transmission and partial reflection by a beam splitter and reflection by a spherical concave mirror,

(2) a background source providing a background image of the game projected by reflection or transmission by a beam splitter,

(3) spherical concave mirror,

(4) a beam splitter inclined at about 45 degrees located in the optical path between the image sources and the mirror, and

(5) a configuration including a video source control section for providing and controlling the video content displayed at the projection image source and the background image source.

The beam splitter may be a 50% transmission / 50% reflection (50T / 50R) type beam splitter, wherein light emitted from the projected source partially passes through or reflects the beam splitter at an approximately 50:50 ratio. The reflection is reflected on the spherical concave mirror and starts to converge, forming a focal point at a specific position outside the system, thereby forming an image of the projected image source outside the system. Therefore, when viewed from the position of the observer, the game character of the projection image source or the image of the game unit appears to protrude. In some cases, the above ratio may use a beam splitter other than 50T / 50R. Since the position of the image of the game character or the game unit is determined by the focal point or radius of the spherical concave mirror, it may be changed as necessary, and more preferably, may be determined by changing the position of the image source.

One or more game characters and game units of the 3D stereoscopic image provided from the projection image source may be selected. That is, in addition to the character or unit that the gamer controls the movement, the character controlled by the programmed contents may also be expressed in the projection image.

The projection image source and the background image source are not particularly limited as long as they can produce an image under the optical structure. However, since the projected image is projected through a greater number of optical elements than the background image, the luminance of the image is relatively lower. Therefore, it is preferable to set the luminance of the projection image source to be higher than that of the background image source. Examples of projected and background sources include PDPs, projection TVs, general color TVs, and computer monitors.

The image source controller receives game contents and operation configuration thereof from a computer to drive a projection image source and a background image source.

Looking at the more specific content of the image source control unit that can be driven,

(A) A computer that provides game content and its composition to display drivers 1 and 2 and provides a synchronization signal to the synchronizer.

(B) Display Driver 1 connected to the projected image source

(C) Display Driver 2 connected to the source on the background

(D) A synchronizer for synchronizing the transmission of information to the display driver 1 and the driver 2 is included.

In some cases, the game system of the present invention may receive the game content and its operating configuration from a communication network such as the Internet and drive the projection image source and the background image source. At this time, the video source control unit,

(a) A network access module for transmitting / receiving information by connecting to a communication network

(b) Multimedia Play Module for playing the received information

(c) Hard Disc Drive to store the reproduced information

(d) Display Driver 1 connected to the projected image source

(e) Display Driver 2 connected to the source on the background

(f) A synchronizer for synchronizing the transmission of information to the display driver 1 and the driver 2 is included.

When the game content and its operation configuration are provided by being connected to a communication network such as the Internet instead of a computer, it is possible to execute a multi-party simultaneous access game.

The game system of the present invention may have a structure in which an audio system and an audio control unit for controlling the same are further added to enable a more lively game production by combining sound with an image.

In order to remove the ghost image created by projecting a light source or image ("external light") outside the game system into the system, preferably in the configuration of the system,

(6) circularly polarized means for circularly polarizing the light beam, located in an optical path between the beam splitter and the spherical concave mirror;

(7) Linear polarization means for linearly polarizing light, located in the optical path between the beam splitter and the end of the optical path to which the projected image can be further included. By the addition of the above configuration, the external light incident on the game system of the present invention is almost blocked before exiting the system, thereby almost eliminating the formation of ghost images caused from the external light source.

Preferably, the circularly polarized means is a quarter wave plate. Thus, one of the main constructions of the present invention for extinction of ghosts is to place a quarter wave plate between the beam splitter and the mirror, thereby keeping the circular polarization of the external light between the quarter wave plate and the mirror. To prevent the elliptic component from being introduced.

More preferably, the configuration includes a quarter wave plate behind the beam splitter inclined at about 45 degrees, in which case the external light incident on the system and linearly polarized by the linearly polarized means on the projection sphere is light of a different orientation. For example, the beam splitter more effectively reflects up and out of the system as compared to unpolarized, circularly polarized or elliptically polarized light. This reduces the brightness of external light in the image forming system and further contributes to the reduction of ghost image formation.

In the prior art, since the linear polarizer and the quarter wave plate are positioned between the ends of the optical path and the beam splitter, the unpolarized light is changed to, for example, horizontal polarization in the linear polarizer and circularly polarized in the quarter wave plate. It passes through the beam splitter. The beam splitter is inclined at an angle other than a right angle, for example, about 45 degrees. When the circularly polarized light passes through the substrate, the elliptical polarization component is introduced to become the elliptical polarized light, so it is reflected by the mirror and passes through the beam splitter again. Because of the distortion, the ghost image is formed without being completely filtered through the linear polarizer.

On the other hand, in the present invention, the external light introduced into the game system is horizontally polarized, for example, by linearly polarized means, maintains horizontally polarized light even through the beam splitter, and is circularly polarized while passing through the circularly polarized means. When the right polarized light is reflected by the mirror, the left polarized light is changed to the left polarized light, and the polarized light is vertically polarized through the circular polarization means, and the vertical polarized light is maintained even through the beam splitter and completely blocked by the linear polarized light means. Therefore, external light applied to the system does not produce a ghost image.

Figure 1 compares an example of a conventional two-dimensional game display system in which a three-dimensional image is given by perspective and one embodiment of a three-dimensional stereoscopic image game display system according to the present invention in which a game character is three-dimensionally projected. Is shown. In the conventional system, the image of the game character is produced on the same two-dimensional plane together with the background image, but in the system of the present invention, the game character is physically separated from the background image and is produced three-dimensionally. In FIG. 1, for convenience of description, a background image in which a game character is separated is displayed in a blank state, but preferably, the background image that is currently produced may be continuous.

2 illustrates a schematic cross-sectional structure of a 3D stereoscopic game system according to an embodiment of the present invention, and a process of generating a projection image and a background image therefrom. Here, a 50T / 50R type beam splitter is used. The operation process is as follows.

Information about the content of the game background image and its operation configuration is transmitted from the computer 300 to the display driver 1 401, and information about the content of the game character and the like is transmitted to the display driver 2 402, respectively. When the synchronization unit 500 is operated, the information of the display driver 1 401 and the driver 2 402 is synchronized, and the image information of the display driver 1 401 is reproduced in the source 600 on the background, and the display driver 2 The image information of 402 is reproduced in the projection image source 700. The game background image from the source 600 on the background passes through the beam splitter 800 and can be recognized at the front of the system with 50% transmission. On the other hand, the image ① from the projection image source 700 passes through the beam splitter 800 with a transmittance of 50% (②), and is maintained at 42.5% when reflected by the spherical concave mirror 900 (③). It is reflected by the beam splitter 800 and becomes 21.25% while passing through the window 1000 having the anti-reflective coating (⑤) and having a luminous intensity of 10.62% compared to the initial luminance of the projection source 700. The projected image is formed to protrude in front of the system. The sound of the game is made from audio embedded in or external to the system by a signal transmitted from the audio control unit 501.

3 illustrates an embodiment of a game system of the present invention operated by receiving information about game content and its operation configuration through the Internet.

When game content and its operational configuration are transmitted from the Internet, the network connection module 100 receives it. The method of transmitting the information may be in a form that can be executed as it is in the system or in a compressed form, but preferably, the information is transmitted in a compressed form. The received information is decompressed and restored by the multimedia play module 200 and converted and reproduced at the same time as multimedia. Such information is stored in the hard disk 310, and the information displayed in the source on the background is passed to the display driver 1 401, and the information to be displayed in the projected image source is sent to the display driver 2 402, respectively. The subsequent process is the same as in FIG. Although not shown in FIG. 3, operation signals generated by gamers while playing games are transmitted to the Internet through the network connection module 100.

FIG. 4 shows a comparison between the prior art expressing an image of a stereoscopic image by perspective in a two-dimensional plane and a system of the present invention expressing a stereoscopic image by a three-dimensional projection image.

5 shows an example of a cross-sectional structure of a game system according to one embodiment of the present invention and an external shape whereby a game is actually executed.

6 and 7 illustrate embodiments of the game system of the present invention that eliminate the generation of ghost images by external light introduced into the system.

In the three-dimensional stereoscopic game display system of FIG. 6A, the light beam 103 from the image source 100 is in a 50:50 ratio displayed for a 50% transmission / 50% reflection (50T / 50R) type beam splitter 800. It partially passes or is reflected through the tilted beam splitter 800. In some cases, this ratio may be other than 50T / 50R. Beam splitter 800 includes a transparent substrate 806, a beam splitter coating 808 or any partially reflective coating, and optionally an antireflective coating 810. The reflected non-polarized light beam 112 passes through a quarter wave plate 114 which has no influence on the light beam 112 because it is non-polarized and then is reflected by the concave mirror 900. The quarter wave plate 114 comprises a quarter wave layer 118 and preferably a transparent substrate layer 160 on the surface of each layer 118. Each layer 160 is preferably coated with an antireflective layer 162. Spherical concave mirror 900 includes a substrate 924, a mirror coating 926 and a protective overcoat 928. After impinging on the mirror 900, the light beam 103 begins to converge toward the focal point determined by the radius of curvature of the mirror 900. The light beam 103 then passes through each plate 114, passes through a beam splitter 800 with a transmittance of 50%, and then passes through a linearly polarized window 130 that polarizes the light beam 103 at about the initial luminous intensity. Pass at 10.6%. Light appears as horizontal polarization. The linear polarization window 130 includes a transparent substrate 132, a linear polarizer 134, and an antireflection film 136. The anti-reflection film is not reflected because the light beam 171 from the external light source 170 is scattered in the anti-reflection film 136. In some cases, the anti-reflection film 136 may be coded on the surface of the transparent substrate 132. The light beam 103 then converges to form an image 701. The exact position of the image 101 depends on the focal point or radius of the mirror 900.

6B shows the transmission as the light beam 103 passes through the system 900.

6C and 6D, the change in the external light incident into the system is described. The transmission of the external light 140 in the system enters the system through the linear polarization window 130, for example, the ratio at which horizontal polarization is obtained. Represents the polarized external light beam 141. Thereafter, the light beam 141 passes through the beam splitter 800 while maintaining its horizontal polarization, and then passes through the quarter wave plate 114 to become a right circle (“RC”). Thereafter, the light beam 141 is reflected from the concave mirror 900 to become a left circle ("LC"), and after passing through the quarter wave plate 114 is vertically polarized light ("VP"). The light beam 141 again passes through the beam splitter 800 and is almost blocked by the linear polarizer 130 to prevent external light from exiting the system, thereby virtually eliminating the cause of ghost formation.

Referring to the three-dimensional stereoscopic game display system of FIGS. 7A to 7D, the system has a quarter wave layer 118 positioned on the beam splitter coating 808 so that the beam splitter 800 and the quarter wave plate structure are provided. It is arranged similarly to the system of FIG. 6A, except for the main difference that forms the combination of 141. As shown, layer 118 is located on surface 843 of beam splitter coating 808 facing mirror 900.

FIG. 7B shows the transmittance of the imaging light passing through the system, achieving the same or nearly the same transmittance as in FIG. 6B despite some changes in the optical path.

7C and 7D show changes in external light incident into the system, similar to the system of FIG. 6A except for some variations along the optical path due to different relative positions of the optical elements, and before exiting the window 130 Since external light is almost blocked, it is effective to almost eliminate the cause of ghost image formation.

The system of FIG. 6A and the system of FIG. 7A may optionally project a second image 246 (indicated by a illusion) and form a visible second image 248 at or near image 701. A second beam splitter 242 (indicated by illusion), preferably tilted at about 45 degrees relative to the castle, black and white or color second light beam 244, preferably a 50T / 50R beam splitter. This additional beam splitter 242 causes the second image 248 to be projected on a different surface than the image 700.

The system of FIG. 6A and the system of FIG. 7A include, for example, one or more additional background sources 600 that project one or more game background images. This background image appears as a virtual image located in the system. An advantage of the background image is that data or a second side of the image can be provided behind the first phase.

Those skilled in the art to which the present invention pertains may make various modifications and applications within the scope of the present invention based on the above contents.

In the 3D stereoscopic game display system of the present invention, since a game character or a game unit is physically separated from a background image and projected to the front of the gamer, the 3D stereoscopic game display system uses a perspective device in a 2D plane or a separate device such as a head mounter. Compared to the game display system of the game, you can enjoy a more three-dimensional and lively game. In addition, by removing the ghost image by the external light projected on the system it is possible to create a more clear three-dimensional image.
