Description

[0001] The present invention relates to a 3D hologram system using 3D glasses,

The present invention relates to a system for implementing a 3D hologram using a spectacles 3D image.

As the interest in stereoscopic image service has been increasing recently, devices for providing stereoscopic images are continuously being developed. There are stereoscopic and auto-stereoscopic methods for realizing such stereoscopic images.

The basic principle of the stereoscopic method is that a plurality of images orthogonal to each other are input to the left eye and the right eye of a human being, and stereoscopic images are generated by combining images input from the left eye and right eye of the human brain. In this case, the fact that the images are arranged to be orthogonal to each other means that the respective images do not interfere with each other. The auto-stereoscopic method is also referred to as a non-eyeglass method.

That is, the method of implementing the stereoscopic image display apparatus can be largely divided into a spectacle method and a non-spectacle method.

FIG. 1 is an exemplary view showing a system of stereoscopic images in a non-eyeglass system.

First, there is a non-point-of-view system in the non-eyeglass system. The above-mentioned multi-view glasses system includes a parallax barrier system and a lenticular lens system.

The Parental Barrier scheme applies a barrier to the display, wherein the barrier consists of vertical lines, and there is a slit between the vertical lines. And the left eye makes the parallax in the right eye by the slit.

The lenticular method arranges the refined small lenses on the display on the display so that the images are refracted by the small lenses to show different images on the left and right eyes.

1 is based on a general parallax barrier system. The stereoscopic image display apparatus 100 includes a display panel 30 and a parallax barrier 20 for simultaneously displaying left and right images.

In this case, the display panel 30 is alternately defined with a left eye pixel L for displaying an image for the left eye and a right eye pixel R for displaying an image for the right eye, The parallax barrier 20 is disposed between the user 30 and the user 40.

The parallax barrier 20 is repeatedly provided with a slit 22 and a barrier 21 for selectively passing light from the left and right eye pixels L and R in a striped pattern oriented in the vertical direction with respect to the user 40 Respectively.

The left eye image displayed on the left eye pixel L of the display panel 30 reaches the left eye of the user 40 via the slit 22 of the parallax barrier 20, The right eye image displayed on the right eye pixel R reaches the right eye of the user 40 via the slit 22 of the parallax barrier 20. At this time, And the user 40 recognizes the three-dimensional image by combining the two images.

In the non-eyeglass 3D display for recognizing the three-dimensional image in accordance with the parallax, when the image is significantly out of the screen (pop-out), the ghost phenomenon occurs in which the user 40 feels dizziness. Due to the ghost phenomenon, the depth of the three-dimensional image is limited.

On the other hand, the currently used hologram is a method of projecting a 2D image onto a semitransparent screen or a two-way mirror using a 2D projector or a 2D display. As the projected image is 2D, 3D stereoscopic effect or 3D volume sensation can not be expressed.

As described above, the object of the present invention is to provide a technique for displaying a stereoscopic image with improved stereoscopic effect without ghosting.

In order to achieve the above object, an embodiment of the present invention proposes a method of providing a stereoscopic image improved in stereoscopic effect by fusing a stereoscopic image and a hologram.

According to an embodiment of the present invention, there is provided a stereoscopic 3D stereoscopic image display apparatus, comprising: a playback apparatus for synchronously reproducing content of a first stereoscopic image and a content of a second stereoscopic image, A second non-eyeglass 3D display for skewing the second stereoscopic image on the screen, and a second non-eyeglass 3D display for refracting the second stereoscopic image by a predetermined angle with respect to the second non- And a lens 230 for generating a 3D hologram image.

The 3D hologram realization system using the spectacles 3D image is arranged in front of the first spectacles 3D display so that the first stereoscopic image is arranged on the rear surface of the hologram, And the spectacles 3D display is arranged on the vertical axis of the first spectacles 3D display.

According to an embodiment of the present invention, a stereoscopic image with improved stereoscopic effect can be provided by integrating a non-spectacles 3D display technology and a hologram technology.

According to another embodiment of the present invention, the depth sense can be controlled by adjusting the interval of the stereoscopic image array.

In addition, according to another embodiment of the present invention, a plurality of stereoscopic images can be seamlessly provided by synchronizing images of a multi-view 3D display.

Prior to the description, '3D', '3D', and 'stereoscopic' mixed in the present invention are used in the same sense.

First, a method for acquiring the spectacles 3D content used in the present invention will be described below with reference to FIGS. 2 and 3. FIG.

2 is a diagram illustrating an example of a stereoscopic image production system according to an embodiment of the present invention.

2, according to one embodiment of the present disclosure, images captured using a plurality of cameras 151 through 159 (hereinafter, referred to as 150) supported by rails 160 The content production apparatus 100 can produce a stereoscopic image. Specifically, it is as follows.

The plurality of cameras 150 are cameras capable of photographing general photographic images, that is, 2D images. The camera 150 may be a digital single-lens reflex camera (DSLR), a digital single-lens translucent (DSLT), or a mirrorless camera. In addition, the camera 150 may be a lens mount type camera or a lens exchange type camera. That is, for example, a wide-angle lens, a standard lens, a telephoto lens, and the like may be exchangeably mounted on each camera 150. The standard lens may mean, for example, a lens having a focal length of 35 mm to 85 mm. The wide angle lens may mean a lens having a focal length of less than 35 mm. The telephoto lens may mean a lens having a focal length of 70 mm or more.

Hereinafter, a lens interchangeable camera will be described, but the present invention is not limited thereto.

It is preferable that the plurality of cameras 150 are capable of capturing a moving image, but it is acceptable if an image can be captured at a speed of several frames per second even if a moving image can not be captured.

The plurality of cameras 150 are supported by the rails 160 so that each of the cameras 150 can be finely moved in the x, y and z axis directions . That is, the rail 160 allows each camera 150 to be linearly moved in the x-axis direction, rotated or linearly moved along the y-axis, and rotated or linearly moved along the z-axis . To this end, the rail 160 may be provided with a motor or an actuator for adjusting each camera 150 in the x, y, and z axis directions.

In FIG. 5, the plurality of cameras 150 are shown as nine cameras, but they may be implemented by at least two cameras.

Meanwhile, the content production apparatus 100 is connected to the rail 160 so that each camera 150 can be finely moved in the x, y, and z axis directions. In addition, the content production apparatus 100 may be connected to each of the cameras 150. At this time, the connection of each camera 150 may be wired or wireless.

The content production apparatus 100 may store an image photographed from each connected camera 150 in an internal memory or an external memory, manufacture the stereoscopic image based on the image, and store the stereoscopic image in the internal memory or the external memory . The memory may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM, a ROM (EEPROM, etc.). ≪ / RTI >

The content production apparatus 100 may control the rail 160 and each camera 150. [ For example, the content production apparatus 100 may control the rails 160 to adjust the cameras 150 to be close to or spaced from each other in the x-axis direction. The x-axis direction distance between the plurality of cameras 150 can be expressed as a distance between lens axes as shown in FIG. At this time, the inter-axis distance between the plurality of cameras 150 can be adjusted according to the average binocular disparity distance of the human and the focal length L of the lens. For example, when three cameras 151, 152, and 153 are used, the inter-axis distance between the first camera 151 and the third camera 153 is determined by the average binocular disparity distance of the human and the focal length L of the lens And the second camera 152 is disposed at the center of the first camera 151 and the third camera 153 and serves as a reference focus as described above or can be used for previewing have.

FIG. 3 is a flowchart illustrating a method for controlling the image production system shown in FIG. 1, and FIG. 4 is a flowchart illustrating a modification of FIG. 5 is an exemplary diagram for explaining the concept of a stereoscopic image.

The schemes shown in Figs. 3 and 4 are described below assuming that the camera 150 is a lens interchangeable camera, but it is not limited thereto.

First, as described above, for example, a wide-angle lens, a standard lens, a telephoto lens, and the like may be interchangeably mounted on each camera 150. Therefore, the content production apparatus 100 acquires information on the focal length L of the lens mounted on each camera 150 (S111).

Subsequently, the content production apparatus 100 acquires distance information to the convergence point intended by the content producer (S113). Convergence point refers to the point where the 3D sensation is zero. Specifically, a convergence point is a point at which the focus of each camera coincides with each other. These convergence points can be adjusted in distance. Therefore, when the main subject, which is an object to be photographed, is set to the convergence point, the main subject is photographed in 2D without stereoscopic effect, that is, without stereoscopic view.

When the convergence point is shot at a point farther away from the subject and then photographed, the stereoscopic view can be expressed as if the subject is located in front of the background located at the convergence point.

Referring again to FIG. 3, the camera 150 may be replaced with a wide-angle lens, a standard lens, a telephoto lens, or the like, as described above. Therefore, the content production apparatus 100 acquires information on the focal length L of the lens mounted on each camera 150 (S111).

Subsequently, the content production apparatus 100 acquires distance information to the convergence point intended by the content producer (S113). Convergence point refers to the point where the 3D sensation is zero. Specifically, a convergence point is a point at which the focus of each camera coincides with each other. These convergence points can be adjusted in distance. Therefore, when the main subject, which is an object to be photographed, is set to the convergence point, the main subject is photographed in 2D without stereoscopic effect, that is, without stereoscopic view.

When the convergence point is shot at a point farther away from the subject and then photographed, the stereoscopic view can be expressed as if the subject is located in front of the background located at the convergence point.

Referring back to FIG. 3, the content production apparatus 100 acquires the width information of the stage at the convergence point (S115). The horizontal width of the stage at the convergence point means the transverse width X of the convergence point at the stage when the distance Y of the convergence point is adjusted to the center of the stage as shown in FIG. At this time, objects located on the foreground than the convergence point are expressed with a sense of depth protruding from the stereoscopic image, and objects located on the rear side of the convergence point can be expressed with a depth sense of retreating from the stereoscopic image.

When the above-described information is obtained, the content production apparatus 100 can calculate the depth of view that can be expressed (S117). That is, as shown in FIG. 5, the content production apparatus 100 can calculate the expressible depth sense (d).

An example of each of the above-described processes will be described below.

In the above-described S113 process, the inter-lens-axis distance x can be calculated as follows.

[Equation 1]

Distance between lens axes (x) = distance to convergence point (Y) / (distance to subject / average distance of human binocular parallax)

Here, the distance to the subject can be 4,000 mm which is optimal for viewing. And the human binocular disparity mean distance may be, for example, 64.5 mm.

Therefore, if Equation (1) is rewritten, for example, the distance between lens axes (x) = Y / (4000 mm / 64.5 mm) can be expressed.

On the other hand, in step S115, the width information of the stage at the convergence point can be obtained by the following equation.

&Quot; (2) "

At the convergence point, the width of the stage (X) = (cameraimic sensor size / L) * Y

Here, L is the focal length of the lens, and Y is the distance to the convergence point. The size of the camera image sensor may be 36 mm on the basis of a film camera.

Then, in step S117, the expressible depth sense (d) can be obtained by the following equation.

&Quot; (3) "

(Maximum focal length of the lens - maximum focal length of the lens - shortest focal length of the lens)) * (maximum focal length of the lens - actual lens ) + (The shortest focal distance of the lens)) * (Y / optimal viewing distance)

Here, the longest focal distance of the lens may be, for example, 55 mm, and the shortest focal distance of the lens may be 18 mm.

If the stereoscopic image display method is a lenticular lens method, the maximum stereoscopic effect displayed on the screen is a maximum viewing distance of 4,000 mm to a maximum of 1,600 mm (actual 1,626 mm), a minimum 800 mm 775 mm).

That is, when the focal length of the lens is 18 mm, a depth of up to 1,600 mm can be expressed, and when the focal length of the lens is 55 mm, a depth of 800 mm can be expressed.

The above table can be summarized as follows.

Distance to convergence point (Y) 4,000 7,000 10,000 Lens Focal Length (L) 55 At the convergence point, the lateral width (X)          2,618          4,582          6,545 Depth feeling (d)             800          1,400          2,000 Distance between axes (x)            64.5          112.9          161.3 18 At the convergence point, the lateral width (X)          8,000         14,000         20,000 Depth feeling (d)          1,600          2,800          4,000 Distance between axes (x)            64.5          112.9          161.3 28 At the convergence point, the lateral width (X)          5,143          9,000         12,857 Depth feeling (d)          1,384          2,422          3,459 Distance between axes (x)            64.5          112.9          161.3

As described above, the content production apparatus 100 can calculate an expressible depth sense based on the acquired information.

Meanwhile, as shown in FIG. 4, the content production apparatus 100 may perform a process different from the procedure shown in FIG. 3 to calculate the focal length of the lens so that the lens to be mounted on each camera can be selected . The sequence of FIG. 4 will not be described in detail, as will be readily understood by those skilled in the art based on the foregoing description.

In addition, in the embodiment of the present invention, a method of acquiring non-spectacles 3D contents by directly shooting with a plurality of cameras has been described, but the present invention is not limited thereto. In another variant, computer graphics can be utilized to acquire a non-eyeglass 3D content such as that shot at the camera's back-point.

FIG. 6 is a flowchart illustrating a method for producing a stereoscopic 3D stereoscopic image through the image production system shown in FIG.

Referring to FIG. 6, the content production apparatus 100 acquires images from the plurality of cameras 150 (S211).

When the image is acquired, the content production apparatus 100 corrects the color of each camera image (S213). That is, the cameras 151, 152, and 153 may coincide with each other because the white balance, the color temperature, the contrast, the name card, the color tone, etc. may be inconsistent with each other.

Next, the content production apparatus 100 corrects the position offset of the image frame of each camera (S214). For example, if the camera 150 is misaligned in the y-axis direction and the z-axis direction on the rail 160 and there is a difference therebetween, there may be an offset between the photographed images. Therefore, the content production apparatus 100 corrects the offset between the images photographed by each camera.

As described above, when the color correction and the offset correction are completed, the content production apparatus 100 synthesizes the images obtained from the respective cameras to generate a stereoscopic image.

Next, a 3D hologram implementation system using stereoscopic image contents generated as described above will be described below with reference to Figs. 7 to 13.

FIG. 7 is an exemplary view illustrating a system for implementing a 3D hologram using a spectacles 3D image according to an embodiment of the present invention, and FIG. 8 is an exemplary view for explaining an arrangement of a stereoscopic image display system according to an embodiment of the present invention to be.

7, according to an embodiment of the present invention, a stereoscopic image array reproducing apparatus 300 (hereinafter, referred to as a reproducing apparatus) using two displays 210 and 220 and a lens 230 Can array stereoscopic images. Specifically, it is as follows.

The reproduction apparatus 300, which has acquired the contents of the two non-eyeglasses 3D stereoscopic images, mixes and synchronizes the first non-stereoscopic 3D stereoscopic image contents and the second non-stereoscopic 3D stereoscopic image contents, And the second non-eyeglasses 3D display 220.

The first spectacles 3D display 210 displays an image of the contents of the first spectacles 3D stereoscopic image reproduced by the reproducing apparatus 300 in a floating manner on the screen, Eye 3D stereoscopic image reproduced by the reproducing apparatus 300 is floated on the screen for display.

An image displayed on the screen of the first spectacles 3D display 210 is referred to as a first stereoscopic image I1 and a second stereoscopic image I2 displayed by the second spectacles 3D display 220 is referred to as a first stereoscopic image I1, Quot;

The lens 230 is used to create a hologram in a floating manner for the second stereoscopic image I2, which is represented by the second non-glasses 3D display 220. The lens 230 is provided to be inclined at an angle of 45 angles with the second non-glasses 3D display 220. This lens can be a TWO WAY MIRROR.

Eye 3D display 210 in order to arrange the hologram I2 'produced by the lens 230 in front of the first stereoscopic image I1, Eyeglass 3D display 220 is placed on the vertical axis of the second non-eyeglass 3D display 220. For example, the second non-glasses 3D display 220 is disposed on the ceiling or floor of a position spaced a predetermined distance in the front direction of the first non-glasses 3D display.

According to this configuration, the hologram 12 'of the second stereoscopic image 12 displayed by the second non-spectacle 3D display 220 is displayed on the first stereoscopic image I1).

At this time, the distance d between the first non-spectacle 3D display 210 and the second non-spectacle 3D display 220 is determined by the maximum pop-out distance of the first stereoscopic image, Depth in distance and an optimal distance between the first stereoscopic image and the second stereoscopic image.

The maximum distance between the first and third stereoscopic images and the maximum depth of the second stereoscopic image and the maximum distance between the first stereoscopic image and the second stereoscopic image are respectively set to a first non- And the distance d between the first and second non-glasses 3D displays 210 and 220 is 0.5 times the width w of the first non-glasses 3D display. It doubles.

First, the first stereoscopic image content and the second stereoscopic image content are acquired as in the embodiment of the present invention (S311). As shown in FIG. 10, nine images are required for a nine-view image as in the embodiment of the present invention. The first stereoscopic image content and the second stereoscopic image content generated for the 9-view image are 9 tile contents. In addition, as shown in FIG. 11, as in the other embodiments of the present invention, each image has a resolution of 1280 x 720 and a total resolution of 7680 x 2160.

The first stereoscopic image content and the second stereoscopic image content thus obtained are made into one file (S312).

A tile image is generated by grouping images of nine tiles into one file, which is a first stereoscopic image content that is nine tiles and a second stereoscopic image content that is nine tiles. At this time, each of the tiles of the first and second stereoscopic images may be referred to as a tile 9 by pairing them.

Each image has a resolution of 1280 × 720, a total resolution of 3840 × 4320, or 7680 × 2160.

The first stereoscopic image and the second stereoscopic image are mixed to generate a raster file (S313).

The first raster file for the first stereoscopic image and the second raster file for the second stereoscopic image are generated.

A raster file refers to a set of consecutive pixels in which an image is composed of pixels in the form of a two-dimensional array, the shapes of these points are combined, and one image information is represented by pixels at regular intervals. In the case of the raster method, the position information of all the pixels is represented in correspondence with the storage location, and then the information stored in the storage location is sequentially read to determine the pixel appearance of the output device at the designated value.

The generated first raster file for the first stereoscopic image and the second raster file for the second stereoscopic image are synchronized and reproduced (S314). In accordance with the reproduction instruction of the reproducing apparatus, the first and third no-spectacle 3D displays output the first and second stereoscopic images, and the output hologram of the second stereoscopic image is arrayed with the first stereoscopic image

For example, for synchronization, the first stereoscopic image content and the second stereoscopic image content may include time information for arbitrary units. It is possible to synchronize the time information.

Further, at the time of reproduction of the reproduction apparatus, the depth sense can be controlled by adjusting the distance between the first stereoscopic image and the second stereoscopic image by the hologram.

 In order to play high-quality (UHD) images of 9 or more images, a large amount of information (9 to 36 times) than the currently used FHD (Full-HD) 2D image must be processed in real time. To this end, the playback apparatus must be able to efficiently compress / reproduce high-capacity contents.

In addition, the playback apparatus may perform an error correction procedure based on the first stereoscopic image and the second stereoscopic image that are synchronized. The error correction procedure includes checking an error and correcting the error of the detected image data (or any tile or one pixel) based on another image in which no error is detected when an error is detected .

For example, it is detected whether the DC coefficient (Direct Current) included in the block-based DCT (Discrete Cosine Transform) coefficient of the image falls within a certain range as compared with the DC coefficient of the surrounding block, , It can be determined that an error is contained in the macroblock.

12 is an exemplary diagram illustrating a method of displaying and setting up a first stereoscopic image and a second stereoscopic image according to an embodiment of the present invention.

As shown in Figs. 12 (a) and 12 (b), display settings can be performed through a display screen of a PC or the like connected to the playback apparatus. The two displays are set to the extended mode in order to reproduce images in the first stereoscopic image and the second stereoscopic image on the first non-spectacles 3D display and the second non-spectacles 3D display, respectively.

In an embodiment of the present invention, a 9-way display is adopted to acquire a stable image when a content is reproduced for a stereoscopic image array. However, since the luminance decreases in proportion to the number of viewpoints and the resolution also decreases with the number of viewpoints, when adopting a 9-way display, adopting a high resolution LCD panel of 4K (3840x2160) Can be prevented.

FIG. 13 is a view illustrating an example in which a stereoscopic image array display system according to an embodiment of the present invention is installed.

13, a first non-spectacle 3D display 210 provided with a front direction of the stage, a second non-spectacle 3D display 220 placed on the bottom of a vertical axis in the front direction of the first non-spectacle 3D display 210, Respectively.

Therefore, the viewer can feel a deeper three-dimensional feeling by fusing the hologram by the image reproduced in the second non-glasses 3D display 220 with the background from the first non-glasses 3D display 210. [

The foregoing description is merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the spirit of the present invention.

Accordingly, the embodiments disclosed in the specification of the present invention are not intended to limit the present invention.
