Description

FIELD OF THE INVENTION [0001] The present invention relates to a stereoscopic image display method,

The present invention relates to a stereoscopic image display method and an apparatus therefor, and more particularly, to a stereoscopic image display method and apparatus for controlling the depth of a plurality of objects based on a distance from a user to a rear wall recognized in real time .

In today's multi-media service centered on digital terminals, which is based on the high-speed information communication network, it is increasingly used as a super-space three-dimensional information communication service that can see, feel, and enjoy three- It is developing.

Generally, a stereoscopic image representing a three-dimensional image is made by the principle of stereoscopic vision through two eyes. Since the parallax of two eyes, that is, the two eyes of the user are separated by about 65 mm, The left and right eyes see slightly different images. Thus, the difference in the image due to the positional difference between the two eyes is referred to as binocular disparity. The three-dimensional image display apparatus uses the binocular parallax to allow the left eye to see only the left eye image and the right eye to see only the right eye image.

In other words, the right and left eyes see different two-dimensional images, and when these two images are transmitted to the brain through the retina, the brain fuses them to reproduce the depth sense and actual feeling of the original three-dimensional image.

The method of driving the stereoscopic image according to the hardware is largely a non-eyeglass system and a glasses system.

In order to display images of two channels in one screen in a stereoscopic image display apparatus, one channel is alternately changed in a horizontal or vertical direction and one channel is output in a row.

In the stereoscopic image output method, the right eye image is transmitted to the right eye and the left eye image is transmitted only to the left eye, thereby displaying a stereoscopic image.

On the other hand, the method of wearing glasses is a method in which the right eye is blocked by the left eye to block the right eye image through special glasses, and the stereoscopic image is displayed by blocking the left eye image from being seen by the right eye.

However, it is not easy to realize a uniform and stable stereoscopic image regardless of the position of the user in the stereoscopic image display device. In the case of a stereoscopic image display apparatus driven by a non-eyeglass system, a technique of tracking a user's position and shifting a liquid crystal field lens accordingly to view a stereoscopic image regardless of a position has been developed. However, although there is an advantage of widening the area in which the stereoscopic image can be viewed in the non-eyeglass system, there is a limit in displaying only the images at two viewpoints from anywhere.

Also, due to the development of electronic technology, various types of display devices have been used in various fields. Particularly, in recent years, research discussions on next generation display devices such as a transparent display device have been accelerated.

A transparent display device refers to a display device that has a transparent property and the background behind the device is transparent. Conventionally, a display panel is fabricated using an opaque semiconductor compound such as silicon (Si), gallium arsenide (GaAs), or the like. However, various application fields that can not be covered by conventional display panels have been developed. Efforts have been made. One of the developments under this effort is a transparent display device.

The transparent display device is implemented in a form including a transparent oxide semiconductor film, and has a transparent property. When a transparent display device is used, the user can see through the object located behind the display device. Therefore, the spatial and visual constraints of existing display devices can be solved.

Such a transparent display device can be used in various environments for various purposes. For example, when the shop window of a shop is implemented as a transparent display device, the user can display information on clothing or bags worn by the mannequin behind the shop window on the show window to provide information. In addition, when a window is implemented as a transparent display device in a general home, a background image selected by a user may be displayed on a window to provide a sense of presence such that the user is located at a desired location.

As described above, the transparent display device has many advantages compared to the conventional display device due to its transparent property. On the other hand, the transparent display device may not be able to display information on the screen due to its transparent property.

Accordingly, a need has arisen for a technique that can more effectively and variously use the transparent display device.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram schematically illustrating a configuration of a display device for displaying a stereoscopic image according to an exemplary embodiment of the present invention.

1, a display apparatus according to an embodiment of the present invention includes an image receiving unit 110, an instruction receiving unit 120, a recognizing unit 130, a control unit 140, and a display unit 150 Lt; / RTI > The image receiving unit 110 can receive a content image transmitted from the outside. The image receiving unit 110 may receive image data transmitted from a broadcasting station and various contents downloaded through various online sites. At this time, the image received through the image receiving unit 110 may include a 2D image or a 3D image. In addition, the image displayed through the display device may include an image stored in a storage device provided in the display device, an image stored in a recording medium connected to the display device, etc., in addition to the image received through the image receiver 110 .

The command receiving unit 120 may receive a command for providing a UI (User Interface) / UX (User Experience). In this case, the command receiving unit 120 can receive a command for UI / UX provision in response to a user gesture or a function or a menu related to UI / UX provision by touch. The command receiving unit 120 may receive a command received from the outside in real time, and the received command may include a command previously set by the user.

The recognition unit 130 may be further divided into a distance recognition unit 131 and a direction recognition unit 132. The distance recognizer 130 may recognize the first distance to the user and the second distance to the rear wall. That is, when a command for providing UI / UX is received through the command receiving unit 120, the distance recognizing unit 131 recognizes the first distance to the user located in front of the display device, The second distance to the rear wall can be recognized. In this case, the first distance and the second distance may be used as a value for controlling a display depth of the objects. In other words, the display device recognizes the distance to the user and the distance to the user through the distance recognizing unit 131, thereby providing a three-dimensional display screen reflecting the depth that the user feels visually with the surrounding environment . Meanwhile, the direction recognizing unit 132 can recognize the direction in which the user is located in real time. At this time, the direction recognizing unit 132 can recognize the direction in which the user is positioned based on the display device.

The control unit 140 may control the depth between the plurality of objects constituting the UI / UX in conjunction with the first distance and the second distance change, and may control to display the plurality of objects. At this time, the controller 140 may enlarge or reduce the size of the plurality of objects in conjunction with the first distance and the second distance change. In a state in which the plurality of objects are displayed, Can be changed. The objects may include a UI / UX screen related to various contents that can be provided in a display device such as a broadcast, a movie, a game, an advertisement, and an SNS as independent images that can be constituted and reproduced independently of the content image.

For example, the information displayed through the display unit 150 may include an image, a text, a content playback screen, an application execution screen, a web browser screen, and various graphic objects. The display unit 150 may be implemented in various forms such as a transparent LCD (Liquid Crystal Display), a transparent OLED (Organic Light-Emitting Diode), and a transparent TFD (Thin Film Diode).

2 is a flowchart schematically illustrating a method of displaying a stereoscopic image in conjunction with a first distance and a second distance change according to an embodiment of the present invention.

2, a display device according to an exemplary embodiment of the present invention recognizes a first distance to a user located in front of the display device and a second distance to a rear wall located behind the display device, The display device may display the three-dimensional effect by adjusting the size of the plurality of objects (or the display depth between the plurality of objects) included in the image based on the recognized first distance and the second distance. First, during display of the content image, a UI / UX provision command can be received (S210, S220). The content video may include video data transmitted from a broadcasting station and contents downloaded through various online sites. The UI / UX providing command may include an instruction previously set in the display device, and may include an instruction to be input in real time.

When the first distance and the second distance are recognized, the display depth between the plurality of objects configuring the UI / UX can be adjusted and displayed in conjunction with the first distance and the second distance change (S230, S240). The first distance and the second distance may be recognized by a distance recognizing unit implemented as a predetermined camera type module provided in the display device. For example, the predetermined module type distance recognizing unit may be provided through a plurality of cameras, and may be provided on the front / rear of the display device. The display device displays three-dimensionally an image so that each of the plurality of objects exhibits a different perspective from each other by displaying different depths on each of a plurality of objects constituting the UI / UX. That is, the display device can freely adjust the depth of the displayed image by adjusting the depth between the plurality of objects. At this time, the display device recognizes the second distance to the rear wall of the display device, which is recognized when the first distance to the user is recognized, and determines the second distance based on the recognized first distance and the second distance, The depth of a plurality of objects can also be adjusted. In addition to the first distance and the second distance, the display device may further set a third distance corresponding to a basic distance value for observing the safe viewing distance. The third distance is changed according to the screen size, and the display distance may be differently applied as the display screen is enlarged or miniaturized.

3 is an exemplary view schematically showing a first distance and a second distance applied to a stereoscopic image according to an exemplary embodiment of the present invention.

3, a display device according to an exemplary embodiment of the present invention recognizes a first distance to a user located in front of the display device and a second distance to a rear wall located behind the display device, The depth of the object can be changed in accordance with the first distance and the second distance change.

More specifically, the display device 310 can recognize the distances for the stereoscopic image display through the recognition module mounted on the display device 310. FIG. The recognition module can be divided into a distance recognizing unit for recognizing a distance change required for adjusting the stereoscopic effect of the stereoscopic image and a direction recognizing unit for recognizing a user position change required for providing an optimized stereoscopic image. The distance recognized by the distance recognizing unit includes a first distance D1 that is a distance to a user located in front of the display device 310 and a rear distance from the rear wall 320 located behind the display device 310, And a second distance D2 which is a distance from the first distance D2 to the second distance D2.

In this case, the safe viewing distance applied in the case of watching TV through the display device 310 may be separately applied as the third distance D3. In setting various functions for the stereoscopic image display, (D3) can be set in advance. Then, when the display device 310 displays the stereoscopic image, the stereoscopic image optimized by applying the predetermined distance to the third distance D3 in addition to the first distance D1 and the second distance D2, Can be provided to the user. That is, the third distance D3 is a safe viewing distance applied for protecting the eyesight of the user, and may be differently applied depending on the size of the display device 310. [ Therefore, the first distance D1 refers to a distance excluding the safe viewing distance (third distance D3) for protecting the user's eyesight from the distance from the display device 310 to the user.

Also, the second distance D2 may be changed by adjusting the position of the display device 310. The display device 310 according to the present invention is capable of moving forward / backward by hanging from a wall or a ceiling and includes a specific device 330 (for example, a display device) capable of adjusting the position of the display device at four corners of the display device 310 , A structure in which the small-sized pulley-type display device is closely attached to or separated from the wall surface). Therefore, the second distance D2 from the display device 330 to the rear wall can be changed based on the position of the display device 310 changed by the specific device 330, so that the second distance D2 ) Can be adjusted to control the stereoscopic effect of the display image.

That is, the display device 310 applies a first distance D1 and a second distance D2, which are recognized through a recognition module provided at a predetermined position, to determine a depth that the user visually senses together with the surrounding environment, It is possible to provide a screen by reflecting on the device 310. In other words, the display device 310 may display the first distance D1 based on the user viewing the screen and the second distance D2 to the rear wall located behind the display device 310, By displaying the depth (or distance) between the objects, it is possible to express a stereoscopic effect that appears according to the difference of perspective of the objects.

Meanwhile, the display device 310 may adjust the display angle of the objects according to a change in the position of the user recognized through the orientation recognition unit of the recognition module. That is, although the 3D display screen provided through the general display device can be limited to the Z-axis value, the display device 310 according to the present invention recognizes the change in the position of the user in real time, The user can realize the virtual space feeling through the automatic interaction and the optical illusion effect by reflecting the change of the Z axis value.

As described above, the display device according to the present invention provides a stereoscopic image considering the second distance to the rear wall existing behind the display device in addition to the first distance to the user, thereby further enhancing the stereoscopic effect of the image Thereby providing an optimized image to the user.

4 is a flowchart schematically illustrating a method of displaying a stereoscopic image in conjunction with a change of a position of a user according to an embodiment of the present invention.

4, the display device according to an exemplary embodiment of the present invention recognizes a change in the position of a user and provides a screen by adjusting the display angle of a plurality of objects on the basis of a change in the position of the recognized user , An optimized screen can always be provided regardless of the location of the display device by the user.

First, the display device can display a content image (S410). The content image may include image data transmitted from a broadcasting station and contents downloaded through various sites.

If the change of the user position is recognized, the angle of the plurality of objects constituting the UI / UX may be controlled and displayed in conjunction with the change of the user position [S420, S430]. That is, the display device can recognize the angle of the direction in which the user is positioned and the angle to the rear wall based on the display device using a recognition module provided in a predetermined area, and based on the recognized angles, The angle of the plurality of objects can be changed and displayed. For example, when the user is viewing an image in the right direction of the display device, the display device recognizes that the user is located in the right direction through a specific direction recognition module mounted on a predetermined area of the display device The angle of the user with respect to the position and the angle to the rear wall can be extracted based on the display device. Then, the display angle of the objects can be adjusted and displayed based on the angle of the extracted user position and the angle to the rear wall.

As described above, according to the present invention, since the display screen can always be gazed at the front regardless of the position of the user, the optimized screen can be provided to maximize the degree of immersion.

5A to 5C are views illustrating an exemplary method of displaying a stereoscopic image optimized by a display device according to an embodiment of the present invention.

FIG. 5A is an exemplary view illustrating a method of controlling a three-dimensional effect by adjusting the depth between a plurality of objects according to an exemplary embodiment of the present invention. Referring to FIG.

5A, a display device according to an exemplary embodiment of the present invention adjusts a depth of a display screen in a manner of adjusting depths of a plurality of objects in conjunction with a first distance D1 and a second distance D2 .

The first distance D1 is a distance to a user 520 located in front of the display device 510 and the second distance D2 is a distance from a rear wall 530 located at the rear of the display device 510 , The first distance D1 and the second distance D2 can be recognized through a specific recognition module included in the display device 510. [ The third distance D3 separately applied is a safe viewing distance recommended for protecting the sight of the user 520. The third distance D3 may be previously set by the user and reflected on the screen. The third distance D3 may be differently applied depending on the size of the display device 510. Therefore, the first distance D1 is a distance from the display device 510 to the user 520 excluding the safe viewing distance (third distance D3) for protecting the vision of the user 520 it means.

The display device 510 can provide a display screen showing an optimized three-dimensional effect to the user 520 in consideration of the recognized first distance D1, second distance D2 and third distance D3 have. At this time, the screen displayed through the display device 510 may include a plurality of objects 511, 512, 513, and 514, and the display device 510 displays the recognized first distance D1 The depth l1 between the plurality of objects 511, 512, 513, and 514 can be adjusted based on the first distance D2, the second distance D2, and the third distance D3.

Therefore, the depth l1 between the plurality of objects 511, 512, 513, and 514 is constant, but it is recognized that different depths are applied to the objects 511, 512, 513, Thus, there is an effect that the screen is three-dimensionally recognized.

5A, the display device 510 may display a plurality of objects 511, 512, 513, and 514 adjusted to a depth of l1. However, the display device 510 may display the entire distance between the first distance D1 and the second distance D2. The depth of the plurality of objects 511, 512, 513, and 514 can be adjusted by using all of the distances. The first object 511 is positioned at the forefront of the space that can be viewed by the user (the boundary between D1 and D3), and the second object 511 is located at the rear end The fourth object 514 may be positioned in the second object 530 and the second and third objects 512 and 513 may be positioned between the first object 511 and the fourth object 514 at a predetermined depth. Thus, the display device 510 can display a plurality of objects 511, 512, 513, and 514 in a three-dimensional manner utilizing the space from the foremost part of the user-viewable space to the rear wall 530.
