BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereoscopic image system, and more particularly, to a method for implementing a stereoscopic image for detecting and displaying a time when a light beam irradiated onto an object is reflected on a three-dimensional space and a system for performing the same.

In general, an imaging system may be referred to as a spatial light modulator for projecting optical energy onto a screen. Such an imaging system can be applied to various fields such as optical communication, image processing, and information display apparatus. In addition, the imaging system is classified into a direct-view image display device and a projection-type image display device according to a method of displaying optical energy on a screen.

An example of a direct-view image display device is a CRT (Cathode Ray Tube). The CRT device is called a CRT, which has excellent image quality but increases in weight and volume as the screen is enlarged, leading to an increase in manufacturing cost. There is.

Examples of the projection image display apparatus include a liquid crystal display apparatus (hereinafter referred to as LCD) and a deformable mirror device (hereinafter referred to as DMD).

Such projection image display devices can be further divided into two groups according to their optical characteristics. That is, devices such as LCDs may be classified as Transmissive spatial light modulators, while DMDs may be classified as reflective spatial light modulators.

An LCD device is a display device that uses a liquid crystal that can electrically control the transmittance of light. A projector using the LCD (hereinafter referred to as a liquid crystal projector) has a very simple optical structure, which makes it possible to reduce the thickness of the LCD device. Can be. In addition, it is widely used as a display device for high-definition television (HDTV) and video conferencing because a large screen and high image quality can be obtained.

A liquid crystal panel used in a liquid crystal projector is commonly known as a matrix liquid crystal panel, in which pixels are arranged in a matrix in two directions perpendicular to each other, and are driven individually by a driving voltage to provide optical Change characteristics. The drive voltage can be applied to the individual pixels by a simple matrix system, and non-linear two-terminal devices such as metal-insulating metal (MIM) or three-terminal switching devices such as thin-film trasistor (TFT) It can be applied to each pixel alternately by an active matrix system arranged for each pixel.

1 is a schematic diagram illustrating a configuration of an image system of a liquid crystal display device which is a type of a conventional image system.

Referring to FIG. 1, the conventional LCD imaging system 10 includes a projection lens 24 for projecting colored light L, and a red light R, a green light G, and a blue light B, respectively. First, second and third liquid crystal plates 20a, 20b and 20c. The transmittance of the first, second and third liquid crystal plates 20a, 20b, and 20c is changed according to an applied image signal to transmit or block red, green, and blue lights. The transmitted light is projected by the projection lens 24 into a ray L comprising three color rays.

In addition, the conventional LCD imaging system 10 includes a lamp 12, a condenser lens 14, a first, second, third, and fourth dichroic filter for emitting light rays. 16a, 16b, 16c, 16d, first and second mirrors 18a, 18b, and first, second, and third fields (Field lenses) 22a, 22b, 22c.

A light source commonly used in the LCD imaging system 10 is a metal halide lamp 12. The condenser lens 14 acts as a convex lens, and serves to focus the light emitted from the lamp 12 at its focus.

The first, second, third, and fourth dichroic filters 16a, 16b, 16c, and 16d are optical filters for selectively passing light by wavelength, and the three primary colors of white light emitted from the lamp 12 are That is, it serves to separate into red light, green light and blue light.

Hereinafter, the operating principle of the conventional LCD imaging system 10 will be briefly described.

After white light is emitted from the halogen metal lamp 12, the white light is focused by the condenser lens 14 and irradiated to the first dichroic filter 16a. Among the white light, the green light G and the blue light B pass through the first dichroic filter 16a, while the red light R is reflected by the first dichroic filter 16a. This red light R is reflected by the first mirror 18a and is incident on the field lens 22a. The red light R having passed through the first field lens 22a passes through the first liquid crystal plate 20a as the transmittance of the first liquid crystal plate 20a, which is an R-liquid crystal plate, changes to a third dichroic light. Irradiated with the blade filter 16c. Since the third dichroic filter 16c is an optical filter that transmits the red light R and reflects the green light G, the red light R passes through the third dichroic filter 16c and is the fourth dichroic filter. The blade filter 16d is irradiated.

On the other hand, the green light G and the blue light B transmitted by the first dichroic filter 16a are reflected by the green light G and the blue light B is transmitted by the second dichroic filter 16a. . After passing through the second field lens 22b, the green light G passes through the second liquid crystal plate 20b as the transmittance of the second liquid crystal plate 20b, which is a G-liquid crystal plate, changes. The green light G passing through the second liquid crystal plate 20b is reflected by the third dichroic filter 16c that transmits the red light R and reflects the green light G, thereby being fourth dichroic filter 16d. Is investigated.

After passing through the third field lens 22c, the blue light B having passed through the fourth dichroic filter 16b passes through the third field lens 22c, and as the transmittance of the third liquid crystal plate 20c, which is a B-liquid crystal plate, changes, Passes through the liquid crystal plate 20c. The blue light B passing through the third liquid crystal plate 20c is reflected by the mirror 18b and irradiated to the fourth dichroic filter 16d.

In this way, the fourth dichroic filter 16d combines three rays, i.e. red, green and blue rays, and the projection lens 24 is a synthesized ray L screen (not shown). Project on the image.

Such conventional LCD and imaging systems implement images on a screen by projecting light or light rays onto a flat screen. Therefore, there is a problem in that it is difficult to implement an image three-dimensionally because of many constraints in space and time.

The present invention has been made to solve the above-mentioned problems occurring in the above-described image system such as CRT and LCD. The first object of the present invention is to irradiate a light beam onto an object to be projected and to reflect the irradiated light beam onto the object.

Here, as shown in FIG. 3, the image signal input unit 120 detects the time and amount of light that the light beams generated by the wavelength generator 122 and the light beams generated by the wavelength generator 122 are reflected by the object. A plurality of object recognition unit 130 is integrated with the detection unit 124 is configured. In other words, the image signal input unit 120 is configured such that the object recognition unit 130 is arranged in a plurality of rows and a plurality of columns on each of the supports 121A and 121B installed to face each other at a predetermined interval.

The object recognition unit 130 of the image signal input unit 120 may be configured such that the wavelength generator 122 and the detector 124 are arranged in one pair from side to side, or one pair is arranged up and down as needed.

Therefore, when a specific object is input between the support members 121A and 121B spaced by a predetermined interval, the wavelength generator 122 irradiates an object with light having a predetermined wavelength, and the detector 124 detects the wavelength generator 122.

4A and 4B are matrix diagrams for explaining data conversion of an image signal generated by a data converter in the stereoscopic image system shown in FIG. 2, and FIG. 5 is a stereoscopic image system shown in FIG. A perspective view for explaining an embodiment of a display device.

In addition, the data converter 140 generates position data corresponding to a reflection time of a light beam of an object input by the object recognition unit 130 of the image signal input unit 120. That is, as shown in (b) of FIG. 4, the position data as shown in (b) of FIG. 4 so as to correspond to the time data of the light reflected from the object by the object recognition unit 130 of the image signal inputter 120 as shown in FIG. Make For example, t ₁₂ in FIG. 4 (a) shows time data reflected by light rays on an object input from the object recognition unit 130 mounted on the first support 121A of the image signal input unit 120. The data converter 140 converts the time data of t ₁₂ into (x ₁₂ , y ₁₂ ), which is predetermined position data, and transmits the same to the display device 160.

In addition, as shown in FIG. 5, the display device 160 connected to the output terminal of the data conversion unit 140 includes a first side of the lower end of the hexahedral body 161 filled with a fluorescent material emitting light only at a predetermined energy level or higher. The light output unit 162A is mounted, and on the other side, the second light output unit 162B is mounted. In addition, the first light output unit 162A and the second light output unit 162B may include a laser (LASER, light amplification by stimulated emission of radiation) light generator (LASER) for converting input power into powerful coherent light or infrared light. And to receive the laser beam at 170.

Each of the first and second light output units 162A and 162B receives a plurality of reflection mirrors M1 through which a laser beam input from the laser light generating unit 170 passes through a plurality of beam splitters Bs1 to Bs2. To M4). Below the plurality of reflection mirrors M1 to M4, a plurality of drive motors 164A to 164D for adjusting the angle of the reflection mirror are mounted.

The plurality of drive motors 164A to 164D rotate forward and reverse by the drive motor controller 142 under the control of the data converter 140 to adjust the reflection angles of the mirrors M1 to M4. As a result, the first light output unit 162A and the second light output unit 162B are driven to preferably cross each other by adjusting the reflection angle of the laser beam according to the data received from the data converter 140.

Hereinafter, the operation principle of the stereoscopic imaging system will be described in more detail.

When an object to be projected is input between the first and second supports 121A and 121B of the image signal input unit 120, the wavelength generator of the plurality of object recognition units 130 mounted on the respective supports 121A and 121B. In 122, the object is irradiated with light or rays.

The light rays generated by the wavelength generator 122 are reflected by the object and detected by the detector 124. At this time, the interval between the first and second supports 121A and 121B of the image signal input unit 120, that is, the respective wavelength generators in the first and second supports 121A and 121B of the video signal input unit 120. When the light generated at 122 is reciprocated, the detected time and amount of light change according to the degree of absorption of the shape of the object.

Accordingly, the data conversion unit 140 sequentially scans the object recognition unit 130 mounted on the first support 121A and the second support 121B of the image signal input unit 120 to determine the shape of the object. Depending on the degree of absorption, the detected data and the amount of light are input. The data converter 140 converts the reflection time data of the light beam input from the object recognition unit 130 into a preset position data value. That is, as shown in FIG. 4 (a), the time data t _{11 to} t _nn reflected by the light beams to the object input from the object recognition unit 130 of the image signal input unit 120 may be converted by the data conversion unit 140. The data is converted into predetermined position data (x _{11 to} y _nn ) and transmitted to the display device 160.

Here, the first support 121A and the second support 121B are scanned in opposite directions to reduce mutual interference of light or light rays.

In other words, the data conversion unit 140 may drive the motors 164A to 164D of the display device 160 according to the position data corresponding to the time data indicating the detection time gap input from the image signal input unit 120. It converts it to drive driver control value.

The data converter 140 transmits the position data generated based on the time data of the object input to the image signal input unit 120 and the reflected light amount information of the object to the display device 160.

Adjust the angle of reflection. That is, as shown in FIG. 4 (a), time data detected according to an object by the plurality of detectors 124 mounted on the first support 121A of the image signal input unit 120 is as shown in FIG. 4 (b). Likewise, the data is converted into position data through the data converter 140. Accordingly, the first light output unit 142A is formed such that the laser output from the laser light output unit 170 intersects at a point corresponding to the position data (x _{11 to} y _nn ) output from the data conversion unit 140. The reflection angles of the first reflection mirror M1 and the second reflection mirror M2 are adjusted.

The reflection angles of the first reflection mirror M1 and the second reflection mirror M2 are adjusted by the first driving motor 164A and the second driving motor 164B which receive the control signal of the data converter 140. .

Similarly, the second light output unit 142B may reflect the third reflection mirror M3 and the fourth reflection mirror according to the position data input to the display device 160 through the second support 121B of the image signal input unit 120. The reflection angle of M4 is adjusted.

As a result, the energy level of the fluorescent material is increased at the point where the laser beams output from the first light output unit 142A and the second light output unit 142B are combined in the main body 161 of the display device 160. According to the method, when each detection point of the input position data is continuously emitted in this manner, a three-dimensional image of an object input to the image signal input unit 120 is generated. The inside of the display device 160 is filled with a fluorescent material that emits light only at an energy level above which the two lasers are combined, so that the single laser light does not emit the fluorescent material, and only emits light when the two laser beams cross.

In this manner, a three-dimensional image may be implemented on an input object in three dimensions.

As described above, the present invention has the effect of irradiating light rays emitted from a light source to an input object, and implementing a three-dimensional image in three dimensions by using a laser or the like according to the time and the amount of light reflected on the object.
