Apparatus for 3D image generator using multiple liquid slit}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional stereoscopic image generating apparatus, and more particularly, to observe a position of a vertical lattice-shaped slit array pattern generated by switching a liquid crystal driving voltage provided to a vertical line of a liquid crystal. The present invention relates to a three-dimensional stereoscopic image generating apparatus using multiple liquid crystal slits that can generate three-dimensional stereoscopic images by providing multiple liquid crystal slits that can be moved depending on the position of the two-dimensional display apparatus and an observer.

Three-dimensional display by binocular parallax, starting with a perspective painting of perspective in ancient Greek mural paintings, about 100 BC, and by BC Della Porta, Italy, about 1600 BC Since the introduction of the first postcard, early researchers have been able to reproduce and enhance three-dimensional effects by Charles Wheatstone, England, David Brewster, Scotland, and Whendell Holmse, USA. It began in earnest, and in 1903 the FE Ives used a parallax barrier to create a stereoscopic stereogram, and in 1918 CW Kanolt A parallax panoramic diagram that secures a defect in which a viewpoint is fixed so that a continuous three-dimensional image can be seen. lax panoramagram) respectively.

The development of three-dimensional image media affects not only the image field but also related industrial effects to the home appliances and telecommunications industry, as well as the aerospace, arts and automation industries, and the technical ripple effect that can be generated is HDTV. It is expected to be much larger than High Definition Television.

In the early days of basic research as described above, stereoscopic movie viewing using polarized glasses is not only popularized today, but various stereoscopic image generation techniques are known, which are represented by glasses and auto glasses, and some of them are laboratory. Beyond stages, it's actually 3D applied images, 3D advertising production, cultural property preservation and exhibition 3D TV and video, computer vision, virtual world experience, simulation training and work, 3D video conferencing, 3D graphics, 3D This is partly applied to the fields of entertainment and 3D movies.

The factors that make humans feel three-dimensional and deep are the physiological factors of vision coming from the characteristics of the eyes, as well as psychological and memory factors from the retina and non-visual factors (hearing, smell, touch, etc.). The three-dimensional display technology is classified into a depth image system, a stereoscopic image system, a three-dimensional image system, and the like based on the display capability of how much three-dimensional image information can be provided to an observer. It is classified into a still picture and a moving picture according to whether there is a motion.

First, the "depth image method" is a method in which a two-dimensional image has a three-dimensional effect in the space in the depth direction than the display surface due to psychological factors and suction effects. The former is commonly used in three-dimensional computer graphics, which displays perspective, superimposition, shading and contrast, and motion by calculation, and the latter is sucked into the space of the image by presenting the viewer with a large viewing angle. It is applied to a so-called IMAX film or the like which induces a three-dimensional effect by a wide-field stimulus by generating an illusion such as thin.

Next, the 'stereoscopic image method' shows spatial information before and after the display surface by displaying the object observed from the direction corresponding to the left and right eyes, that is, two images with parallax, separately from each other without confusing the left and right eyes to feel a three-dimensional feeling. One way. This type of glasses uses special glasses with different characteristics with respect to the wavelength of light and polarization plane, and when images with parallax are presented on the same plane, each image is separated from side to side by putting a highly directional display plane on the plane. There is a display surface method, that is, a glasses-free method, which makes the user feel the three-dimensional effect by entering the right and left of the.

The spectacle glasses include a wavelength-selective sunglasses (color modulation) scheme, a polarizer polarized glasses scheme using a light shielding effect, and a time-division glasses scheme alternately presenting left and right images within an afterimage time of an eye. In addition, there is a method in which a filter having different transmittances is mounted in the left and right sides to obtain a stereoscopic effect on the movement in the left and right directions according to the time difference of the visual system coming from the difference in the transmittances.

In addition, there is a parallax stereogram method, a lenticular method, a corne cube mirror, and a holographic type in the autostereoscopic method, which generates a three-dimensional effect on the display surface rather than the observer side. There is a directional screen method using a holographic method or the like.

Depth and stereoscopic images reproduce only the information before and after (depth) of the object, so that the object cannot be viewed from various directions that the observer observes, or the object cannot be focused even if some observation is made. There is a problem with the way it is reproduced.

To solve this problem, the three-dimensional image method is representative of depth multi-view, sampling method, and holographic display method, and the three-dimensional image method limits the viewing direction by reproducing a three-dimensional stereoscopic image in space. And some problems such as being unable to focus.

There are parallax barriers, lenticulars, and integrals. The depth sampling method includes a display surface vibration method, a variable cylindrical mirror method, a rotating cylinder method, a display surface stacking method, and a semi-transmissive mirror synthesis method. This method, which requires a mechanical moving part, is a display method using the afterimage time of the eye, and there is a problem in the scanning speed to display an image having a lot of depth information within the afterimage time.

In addition, display surface lamination and transflective mirror synthesis have a problem in that it is difficult to increase the number of depth images.

On the other hand, the holographic method is known as the most excellent method of three-dimensional image display, which includes laser light reproducing holography and white light reproducing holography, but a large amount of data is required for displaying an object and a large cost is required to increase spatial resolution. There is a problem such as being.

Hereinafter, some of the methods for improving understanding of the present invention among the three-dimensional image display methods according to the related art will be described.

1 is an exemplary diagram illustrating a lenticular lens array method, which is an example of a 3D image display method according to the related art.

In the lenticular lens array method, as illustrated in FIG. 1, a display surface in which image information L to be input to the left eye 120 and image information R to be input to the right eye 121 are alternately arranged along the horizontal direction ( 100 and the optical information about the image information L to be input to the left eye 120 and the image information R to be input to the right eye 121 interposed between the display surface 100 and the left and right eyes 120 and 121. It consists of a semi-cylindrical lenticular lens array 110 that provides differential directivity.

Images are separated into the left eye 120 and the right eye 121 according to the directivity characteristics provided by the lenticular lens array 110 to be connected in three dimensions. That is, the image information L to be input to the left eye 120 is observed only to the left eye 120, and the image information R to be input to the right eye 121 is only observed to the right eye 121, and thus, among the visual physiological factors. By obtaining depth information through a binocular parallax having a large effect of the three-dimensional effect, a three-dimensional effect is sensed.

In order to record as many multicular images as possible, the lens aperture of the camera should be made small. This reduces the film width and degrades the image quality. The size F` of the flipping phenomenon in which the image is discontinuous due to the distance between the cameras is expressed by Equation 1.

Where d 'is the pitch of the camera or projector lens, a' is the spacing between the lens and the lenticular array, and b 'is the spacing between the lenticular array and the film.

On the other hand, it is known that the optimum lens pitch of the lenticular array is 0.1 to 0.5 mm, and the observation information is preferably recorded from at least five directions or more.

2 is an exemplary view showing a method using a slit, which is another example of a three-dimensional image display method according to the prior art.

The method using a slit is commonly referred to as a parallax method, and instead of using a lenticular array of semi-cylindrical lenses arranged as shown in FIG. 2, a parallax barrier having a vertical lattice shape is shown. The image information L to be input to the left eye 220 and the image information R to be input to the right eye 221 in a horizontal direction by using the method 210 (also referred to as a slit). It is similar to the lenticular method in that the display surfaces 200 are alternately arranged.

The method using the slit is a representative method of expressing a three-dimensional effect mainly using the binocular parallax characteristic of human vision together with the lenticular method described above.

At this time, the parallax barrier 210 allows the image to be separated and observed through an aperture of a vertical grid in front of the L and R images corresponding to the left and right eyes 220 and 221.

The position of the aperture, the width of the slit, and the pitch of the barrier vary depending on the image width, and the barrier is disadvantageous because the brightness is lowered.

이하로 설정하도록 권고되고 있다. 예컨대, 개구와 눈과의 거리가 1m이면, 피치는 약 0.3mm가 되고, 슬리트의 폭은 피치의 약 0.1배인 3μm정도가 적당하다. 그러나, 이 방법은 제작이 까다롭고 회절 현상에 의해 발생하는 각종 문제로 인해 현재는 거의 사용하지 않는다.In order to eliminate the unobtrusive drawbacks, the pitch of the barrier should be approximated from the limit of the retinal resolution.

It is recommended to set the following. For example, if the distance between the aperture and the eye is 1 m, the pitch is about 0.3 mm, and the width of the slits is about 3 m, which is about 0.1 times the pitch. However, this method is difficult to manufacture and is currently rarely used due to various problems caused by diffraction.

Meanwhile, another example of the three-dimensional image display method according to the related art is a depth direction sampling method.

The principle of the depth sampling method is that if a number of two-dimensional cut images are obtained at each position of an object, the information in the depth direction is divided and displayed by moving the imaging system. You can raise a prize. In this method, since a complete image with depth information is reproduced in space, moving the eye position up, down, left and right, the image viewed from that position can be observed. There are a display surface vibration rotation method and a display surface laminated semi-transmissive mirror synthesis method.

3 is an exemplary view showing a method using a variable focus mirror which is another example of a display surface vibration rotating method according to the prior art.

The method using a varifocal mirror—or a method using vibration optics—has been proposed since 1961 by T. Muirhead, which is shown in FIG. 3. As shown, a thin film mirror is attached to the surface of the vibrating speaker 260 to provide observation of the cutting plane of the object formed on the monitor 270 such as a cathode ray tube (CRT) through the mirror. It uses the phantom imaging effect to make it look like. Accordingly, the observer 250 feels three-dimensional by observing the virtual image 280 of the monitor.

However, in the case of autostereoscopic 3D image display methods, which generate a three-dimensional effect on the display surface rather than on the observer's side, the depth image and the stereoscopic image are reproduced by the observer as they reproduce only the information before and after (depth) of the object. There is a problem in the way of reproducing the spatial image due to factors such as the inability to observe an object from various directions or even to make some observations.

In other words, the three-dimensional image display method according to the prior art is a stereoscopic effect generated by being separated into the left and right eyes, respectively, is possible only in a certain position, and if the deviation from the predetermined position, the left and right images are reversed or inappropriate image separation for the left and right directions There is a problem that the distorted three-dimensional image is observed.

In particular, in the method using the slit parallax barrier, left and right image information incident on the left and right eyes are separated only at a predetermined position, and when left out of the position, the left and right images are inverted or not separated, thereby distorting the image. In addition, as the horizontal resolution is degraded, the degree of deterioration of image quality is severe, and when observing a general two-dimensional image, there is a problem in that the two-dimensional image is distorted.

Accordingly, the present invention has been made to solve such a problem, and to solve the problem, it is possible to solve the multiple liquid crystal slits generated by switching the liquid crystal driving voltage applied to the vertical lines of the liquid crystal in order to use the binocular parallax of human vision. By constructing a three-dimensional stereoscopic image with improved horizontal resolution and time-base resolution, it is possible to create a three-dimensional stereoscopic image while maintaining the horizontal resolution while easing the positional fixation of the observer to observe the three-dimensional stereoscopic image, and without general deterioration of image quality. It is an object of the present invention to provide a three-dimensional stereoscopic image generating apparatus using multiple liquid crystal slits capable of displaying two-dimensional images.

As shown in FIG. 4, a preferred embodiment of a three-dimensional stereoscopic image generating apparatus using multiple liquid crystal slits according to the present invention,

In the three-dimensional stereoscopic image generating apparatus for reproducing a three-dimensional effect on an optical image using the binocular parallax characteristic of human vision,

A display device 300 for displaying a two-dimensional image signal;

Liquid crystal slits installed spatially between the display device 300 and the observer 400 to provide binocular parallax observation for observing three-dimensional stereoscopic images through a slits array pattern having a vertical lattice shape. Array generator 330;

The slit array pattern of the slit array pattern generated in synchronization with the rearranged image generator 320 and controlling the liquid crystal driving voltage provided to the vertical line of the liquid crystal slit array generator 330. It is configured to include a liquid crystal drive control unit 340 that is driven and controlled to provide binocular disparity while the shape varies depending on the position of the observer 400.

The operation of the preferred embodiment of the three-dimensional stereoscopic image generating apparatus using the liquid crystal lens according to the present invention configured as described above will be described with reference to the accompanying drawings.

5 is an exemplary diagram illustrating an example of obtaining a two-dimensional view image.

First, the multi-view image acquisition apparatus 310 of the present invention is based on the binocular parallax characteristic of the three viewpoints of the left, right, and center as shown in FIG. When imaging is performed in a, b, and c), two-dimensional view images of a, b, and c images are respectively displayed as shown in FIGS. 5B, 5C, and 5D. Acquire each. As the same subject is photographed by three different cameras at different angles, the shapes and positions of the photographed subjects differ according to viewpoints (ie, photographing angles). Here, FIG. 5 illustrates a slightly exaggerated deflection of the object viewed from each viewpoint for convenience of description.

In the preferred embodiment of the present invention, the number of two-dimensional viewpoint images is suggested to be three, but it is sufficient that the number of two-dimensional viewpoint images is two or more. On the other hand, when using too many two-dimensional view images, the apparatus for processing them is complicated and does not contribute to the improvement of the three-dimensional feeling that can be felt by human beings. In consideration of the performance and performance, it is desirable to select a suitable level.

Thereafter, the rearranged image generation unit 320 receives the same number of two-dimensional viewpoint images as the plurality of viewpoints from the multi-view image acquisition apparatus 310, and the two-dimensional viewpoint from the multi-view image acquisition apparatus 310. The method of receiving an image may be performed through a wired or wireless communication network, such as broadcasting, or may be performed by a device in which the rearranged image generating unit 320 and the multi-view image obtaining apparatus 310 are integrated.

The rearranged image generating unit 320 maintains pixel position information of each two-dimensional viewpoint image based on binocular parallax characteristics, and the image information to be input to the left eye and the image information to be input to the right eye are horizontally aligned in units of predetermined pixel intervals. And rearranging rearranged viewpoint images to be alternately arranged along the time direction axis, and providing the rearranged viewpoint images to the display apparatus 300.

In more detail, the rearranged image generating unit 320 captures the same subject at a plurality of viewpoints in order to show different stereoscopic images according to the viewing direction of the observer 400 of FIGS. 5B and 5. (c), the image of FIG. 5 (d) is separated at finely equal separation intervals in the vertical direction. However, the separation interval is set in predetermined pixel interval units along the horizontal axis of the image. In other words, image a is divided into image pieces a1, a2, a3, a4 ..., a, and image b is image pieces b1, b2, b3, b4 ..., bn The image c is separated into image pieces c1, c2, c3, c4 ..., cn.

Subsequently, the image pieces are sequentially mixed in the order of the respective viewpoints, and as shown in FIG. 6, the rearranged viewpoint images, which are new images in which the images of each viewpoint are mixed, are reconstructed. That is, the image information to be input to the left eye while maintaining the pixel position information of each two-dimensional viewpoint image -a picture fragment-and the image information to be input from the center of both eyes as the reference viewpoint -b image fragment to the right eye and the right eye The rearrangement time point image which is a new image is reconstructed by rearranging so that the image information -c image fragment of the image to be inputted to-is alternately arranged along the horizontal axis direction in predetermined pixel interval units.

6, which is an example of a reconstructed rearrangement time point image, shows that any single line is a1, b2.c3 a4, b5.c6, ..... a (n-2), as shown on the left. The image pieces are arranged in the order such as, b (n-2), cn.

As a reconstruction example of the rearranged viewpoint images that can be arranged in this manner, a reconstruction example of the new rearrangement viewpoint images equal to the number of viewpoints at the time of photographing and the same number depending on the start time can be made. Referring to FIG. 7, the first rearrangement time point image is a1, b2.c3 a4, b5.c6, ..... a (n-2), b (as shown in FIGS. 6 and 7 (a). n-2), cn, and the second rearrangement time point image is b1, c2.a3 b4, c5.a6, ..... b (n-2), c (n−, as in (b) of 7). 2), an, and the third rearrangement time point image is c1, a2.b3 c4, a5.b6, ..... c (n-2), a (n-2, as shown in FIG. ), bn. In this case, n is the total number of image pieces and is determined by dividing the size of the image by a predetermined pixel interval.

As such, the display apparatus 300 provides the display device 300 with a first rearrangement time point image, a second rearrangement time point image, and a third rearrangement time point image that are rearranged to be alternately disposed along the horizontal direction axis and the time direction axis in predetermined pixel intervals. By sequentially displaying the image, the slits array pattern of the liquid crystal slit array generator 330 disposed between the display apparatus 300 and the observer 400 is adjusted to show images of different views according to angles.

In this case, the liquid crystal driving controller 340 synchronizes with the rearranged image generating unit 320 and controls the liquid crystal driving voltage provided to the vertical line of the liquid crystal slit array generating unit 330. If the shape of the slit array pattern is varied according to the position of the observer 400 and is driven and controlled to provide binocular disparity, the liquid crystal slit array generator 330 accordingly slit the vertical lattice shape. Slit array pattern provides binocular disparity for observation of 3D stereoscopic images.

Hereinafter, the above operation will be described in more detail.

로 저하된다.The first rearrangement viewpoint image, the second rearrangement viewpoint image, and the third rearrangement viewpoint image illustrated in FIG. 8 are images in which information of three viewpoints (left, right, and center) exist at the same time. In the viewpoint image, as described above, after subsampling the image of each viewpoint, the horizontal resolution is increased by sequentially arranging the images.

Is lowered.

When the liquid crystal slit corresponding to the center viewpoint image (here b image) is opened among the multiple liquid crystal slits of the liquid crystal slit array generator 330 provided in front of the display apparatus 300 in which the rearranged images are displayed, As shown in Fig. 8, at the center view, the subsampled center view image (here, b image) is shown, the left eye is subsampled, and the left eye view image (here, a image) is shown, and the right eye is subsampling. The right eye viewpoint image (here, c image) is seen.

In this case, a different image is displayed according to the viewing point, and the start point image of the image displayed on the display device 300 is changed to create rearrangement point images of the number of points of view, and are sequentially output to the display device 300. Overcome the problem of degradation of resolution.

The first rearrangement point image in which the image fragment of the a image starts first is called A picture, and the second rearrangement point image in which the image fragment of b image starts first is called B image, and the image fragment of the c image starts first When the third rearrangement viewpoint image is referred to as a C image, the A, B, and C images are sequentially output to the display device 300, and at the same time, the liquid crystal slit in front of the center viewpoint image (here, b image) of each image is opened. Then, as shown in FIG. 9, image information of all viewpoints is transmitted to the observer 400 without missing information to maintain the original horizontal resolution.

9 is an exemplary diagram illustrating an example of reproducing a continuous image composed of a number of viewpoints composed of western-sampled pixel pieces and an equal number of rearranged viewpoint images as a three-dimensional stereoscopic image.

On the other hand, when viewing a general two-dimensional image, all the liquid crystal slits of the liquid crystal are opened so that the two-dimensional image is not adversely affected in view of resolution.

10 is an exemplary view illustrating an example in which the liquid crystal slit pattern is changed according to the position of the observer moving from side to side.

When the position of the observer 400 moves to the left and right, the image information viewed by the observer 400 changes, and if it is severe, the image is distorted to the left and right and the image is distorted.

In order to avoid such a phenomenon, as shown in FIG. 10A, the pattern of the liquid crystal slit is shifted so that accurate information is transmitted to the observer 400.

That is, as shown in FIG. 10B, the distance between the liquid crystal slits is adjusted to optimize the distance of the observer.
