Hereinafter, to facilitate understanding of the present invention and for convenience of applicants, data including the 3D object will be referred to as an application or an application including a 3D object.

3D Concepts and Formats

First, the basic principle of 3D and its format will be briefly described as follows.

Generally, a 3D image (or a stereoscopic image) provides a stereoscopic feeling by using the stereoscopic principle of the human eyes. Since the human being feels the perspective through the binocular parallax due to the difference between the two eyes, that is, the distance between the two eyes about 65 mm away, the 3D image provides the image so that the left eye and the right eye are respectively associated with the plane image It is possible to provide three-dimensional feeling and perspective.

Generally, a 3D image (or a stereoscopic image) provides a stereoscopic feeling by using the stereoscopic principle of the human eyes. Since the human being feels the perspective through the binocular parallax due to the difference between the two eyes, that is, the distance between the two eyes about 65 mm away, the 3D image provides the image so that the left eye and the right eye are respectively associated with the plane image It is possible to provide three-dimensional feeling and perspective.

FIG. 1 is a diagram for explaining a perspective view that allows a user to perceive a stereoscopic effect according to a time difference between a left image data and a right image data, in relation to the 3D principle.

Fig. 1 (a) illustrates the position 103 of the image formed by the combination of the two data when the parallax between the right video data 101 and the left video data 102 is narrow. 1 (b) shows the position 113 of the image formed by the combination of the two data when the parallaxes of the right video data 111 and the left video data 112 are relatively wider than those of FIG. 1 (a) . 1 (a) to 1 (b), images are formed at different positions (or distances) from the left and right eyes according to the parallax of the left / right image data. I can feel it.

In Fig. 1 (a), an image 103 is formed by extending lines R1 and R2 for viewing one side and the other side of the right image data 101 to the right eye, and in the same manner for left image data 102 for the left eye An extension line R1 for the right image data and an extension line L1 for the left image data are formed at a point where they intersect at a certain distance d1 from the right eye and the left eye when the extension lines L1 and L2 are drawn. 1 (b), the image 113 includes an extension line R3 for the right image data and an extension line L3 for the left image data at a certain distance d2 from the right eye and left eye, At the intersection point. Here, when d1 (Fig. 1 (a)) and d2 (Fig. 1 (b)) showing distances from the binocular to the positions 103 and 113 are compared, the distance d1 is longer from both eyes than d2. That is, the image in Fig. 1 (a) is formed at a greater distance from the binocular than the image in Fig. 1 (b).

This is caused by the interval of the left / right image data (lateral direction with reference to the drawing). For example, the interval of the right / left image data 101/102 in FIG. 1 (a) is relatively narrow as compared with the interval of the right / left image data 103/104 in FIG. 1 (b). 1 (a) and 1 (b), the image formed by the combination of the left / right image data becomes relatively distant from the human eye and distant as the interval of each image data becomes narrower.

According to the present invention, there are a stereoscopic image method considering two viewpoints and a multiple view image method considering three or more viewpoints. In contrast, the conventional single view image method is referred to as a monoscopic image method.

In the stereoscopic image method, a pair of left and right images obtained by photographing the same object with the left camera and the right camera separated by a predetermined distance are used. The multi-view image uses three or more images acquired from three or more cameras having a certain distance or angle.

The stereoscopic image or the multi-view image may be compression-coded and transmitted in various ways including MPEG (Moving Picture Experts Group). For example, a stereo image or a multi-view image may be compression-coded and transmitted by the H.264 / AVC (Advanced Video Coding) method. At this time, the digital broadcasting receiver can obtain a 3D image by decoding an image received inversely to the H.264 / AVC coding scheme. Also, one of the left image data and the right image data of the stereoscopic image or one of the multi-view images is allocated as a base layer image and the remaining image is assigned as an extended layer or enhanced layer image, The image of the base layer may be encoded in the same manner as the mono-scopic image, and the image of the enhancement layer may be encoded and transmitted only for the relationship information between the base layer and the enhancement layer. Here, JPEG (Joint Photographic Experts Group), MPEG-2, MPEG-4, H.264 / AVC, or the like can be used as an example of the compression encoding method for the base layer image. In addition, H.264 / MVC (Multi-view Video Coding) scheme can be used as a compression coding scheme for an image of an upper layer. The above-described compression encoding method is merely an example, and it is obvious that other compression encoding methods may be used.

In addition, the transmission format of the stereoscopic image is a single video stream format and a multi video stream format. The single video stream format multiplexes video data of two viewpoints into one video stream and transmits the video data to one video stream. Therefore, the bandwidth required for providing a 3D broadcast service bandwidth is not large. The multi-video stream format is a scheme of transmitting a plurality of video data in a plurality of video streams, and has an advantage of displaying high-quality video data by enabling a high-capacity data transmission with an increased bandwidth.

2 is a diagram illustrating a stereoscopic image multiplexing format of a single video stream format.

The single video stream format includes a side-by-side of (a), a top / bottom of (b), an interlaced of (c), a frame of a frame sequential, a checker board in (e), anaglyph in (f), and the like.

The side by side format of (a) is a method in which the left image and the right image are down-sampled by 1/2 in the horizontal direction, and one sampled image is displayed on the left side and the other sampled image is displayed on the right side Thereby constructing one stereoscopic image. In the top / bottom format of (b), a left image and a right image are respectively down-sampled by 1/2 in the vertical direction, and one sampled image is placed on the upper side and the other sampled image is placed on the lower side, Construct a scopic image. The interlaced format of (c) is a format in which the left image and the right image are respectively down-sampled by 1/2 in the horizontal direction so as to cross each line, So that two images are composed as one image. The frame sequential format of (d) constitutes one video stream by temporally crossing the left video and the right video. In the checkerboard format of (e), two images are formed as one image by downsampling the left and right images so as to intersect in the vertical and horizontal directions, respectively. The anaglyph format of (f) constitutes an image so as to produce stereoscopic effects using complementary color contrast.

3 is a diagram illustrating a stereoscopic image multiplexing format of a multi-video stream format.

the full left / right format of (a) is a case of sequentially transmitting the left video and the right video, and the full left / half right format of (b) And the right image is transmitted by 1/2 sub-sampling in the vertical or horizontal direction. The 2D video / depth format of (c) is a case of transmitting one image of a left image and a right image together with depth information for generating another image.

It is necessary for the receiving system to transmit information on the multiplexing format described above in order to efficiently demultiplex video data transmitted in these various ways to process the video data.

In the foregoing, we have briefly discussed the 3D concept and format. Hereinafter, in order to facilitate the understanding of the present invention and for the convenience of explanation, the present invention will be described herein with reference to a case where a 3D object included in general 3D contents is displayed in a TV platform using a specific API (Application Programming Interface) eye view and a right eye view, which are divided into a left scene and a right scene to render the 3D effect maximized. Hereinafter, stereoscopic is described as an example, but the present invention is not limited thereto, and it will be apparent that the present invention can also be applied to multi-view images.

Stereoscopic image processing device

Hereinafter, a stereoscopic image processing apparatus for processing an application including one or more 3D objects will be described in detail. Here, the application including the 3D object may be received by the stereoscopic image processing apparatus in various ways. The various methods include, for example, a method in which an application is included in a data broadcasting signal through a data broadcasting channel, a method in which data is transmitted from an external storage device such as a USB (Universal Serial Bus) or an external HDD, Or may be transmitted through various servers connected through a network.

Accordingly, in the present specification, for the sake of convenience of explanation, the control unit 402, which is a part in which a 3D object is processed, an image according to a 3D image output method in accordance with an output frequency of the display module 404 The rest of the components except for the output formatting unit 403 and the display module 404 perform a common function, but their configurations may be different according to each method, and will be referred to as a basic processing unit 401. FIG.

4 is a block diagram illustrating a digital broadcasting receiver according to the present invention.

The digital broadcasting receiver includes a basic processing unit 401, a control unit 402, an output formatter unit 403, and a display module 404.

The control unit 402 includes a middleware layer (M / W), and an application including a 3D object is located on the middleware layer. Hereinafter, the control unit 402 may be used in combination with the middleware (M / W).

The configuration of the basic processing unit may have an appropriate configuration depending on the path or manner in which the application including the 3D object described above is transmitted.

For example, when an application including a 3D object is transmitted in the form of a data broadcasting signal, the basic processing unit 401 may include a tuner unit, a demodulator, a demultiplexer, a signaling information processor, an application controller, , A UI control unit, a storage unit, and a mixer unit. Here, the tuner unit receives a data broadcasting signal for tuning a specific channel and transmitting an application including the 3D object. The demodulator performs demodulation by a demodulation system corresponding to the modulation scheme of the received data broadcasting signal. The demultiplexer demultiplexes the demodulated data broadcast signal into an application including the 3D object and other information. The signaling information is received and processed in SI (System Information) information. The application control unit includes a channel manager and a channel map for controlling the generation of the channel map based on the SI information. The control unit controls all operations of the system. The UI control unit controls operations on the processing of the UI to be provided with execution of the application including the 3D object. The storage unit stores various information to be input. The mixer unit processes the input signal or data as needed to suitably mix.

Further, in the case of receiving an application including a 3D object through a network via an internet protocol, a configuration (for example, an IP physical interface) for receiving and processing an IP packet in the above-described configuration is further added in the above- Configuration can be substituted.

In addition, when the data is received through an external storage device or the like, an external input receiving unit and the like may be further included in the above-described configuration.

The digital broadcast receiver may be, for example, a digital television receiver. Therefore, the digital broadcast receiver may be further added with some configurations other than the configurations shown, except for some of the configurations shown, or vice versa. Further, each of the above-described configurations may be merged if necessary to function as a single configuration. In addition, the application control unit 405 may include a channel-related channel manager 406 and a channel map 407, and may further include an audio / video decoder 411/412, a scaler 413, and a video processor 414 have. In addition, the digital broadcast receiver includes APIs necessary for controlling the 3D effect for the application including the 3D object according to the present invention.

The digital broadcast receiver of FIG. 4 may also process 2D content and typical 3D content. For example, when the 2D content is input, it is possible to perform unambiguously processing by controlling some configuration, for example, the output formatting unit 419, which is specialized for 3D content processing, by-pass.

Hereinafter, the functions and functions of the control unit 402 will be described in more detail with reference to the present invention.

When an application including a 3D object input from the basic processing unit 401 is received, the primary processing unit 401 performs a primary processing on the received application, and requests the control unit 402 for subsequent processing.

The control unit 402 invokes the parent application using the specific API according to the request.

Here, the control unit 402, that is, the middleware (M / W) analyzes an application called through a Java Virtual Machine (JVM) 411 included therein.

The control unit 402 performs basic setting and rendering of the 3D objects included in the application using a specific API according to the analysis result. Here, the API used for the basic setting and rendering may be, for example, a Mobile 3D Graphics (M3G) Camera API.

That is, the control unit 402 sets the view port for each 3D object according to the result of the application analysis, and renders it so as to have a 3D effect. In the present invention, stereoscopic is illustrated for convenience of explanation, but it is not limited thereto, and it is obvious that the present invention can be applied to other 3D display methods illustrated in Figs.

The 3D platform of the digital broadcast receiver according to the present invention can support both mono and stereoscopic modes. Accordingly, when the user selects the camera based on the analysis result, the control unit 402 adjusts the angle, distance, etc. of the camera based on the user's configuration information based on the analysis result at runtime So that the left and right images can be generated and rendered in software.

In addition, the 3D platform of the digital broadcasting receiver according to the present invention may include a window size, a camera angle, a distance, and the like so that a user can select a desired resolution and three-dimensional sensation based on the analysis result, It may provide configuration information that can be modified at runtime.

In addition, the 3D platform of the digital broadcast receiver according to the present invention can support both a passive mode and an active mode for displaying a 3D image. In the following description, the passive method will be described as an example for convenience of explanation, but the present invention is not limited thereto. In passive mode, there are single video stream formats such as side-by-side, top / bottom, interlaced and frame sequential formats and dual video stream formats And the 3D effect can be further enhanced by selecting an appropriate method in consideration of the resolution and the like of the video signal processing apparatus.

The control unit 402 extracts 3D objects by analyzing the application to give a 3D effect. The control unit 402 generates a scene graph based on the user's configuration information and the like with respect to the extracted 3D objects. Here, the scene graph manages and controls a viewport, a light, a mesh, a texture, and the like of an object modeled according to an input selected by a user.

The control unit 402 reads the set view port using the generated scene graph and performs rendering according to the mode selected by the user using the high level API related to rendering. The above mode may include a mono mode and a 3D mode as described above. In the case of the 3D mode, the 3D mode can be defined in more detail according to various 3D formats. However, as described above, the stereoscopic mode will be described below for the sake of convenience of description.

5 is a conceptual diagram for explaining how a mono eye and a stereo view port are divided according to the present invention.

For example, when the user selects mono, the control unit 402 sets the viewport as a mono eye in Fig. In this case, the control unit 402 finishes the operation in the selected mono mode by rendering the view port only on the view angle of the existing content and rendering it on one screen.

In contrast, when the user selects the stereo mode, the control unit 402 sets the view port in each of the left eye and the right eye in FIG. 5, that is, sets two view ports to transmit images through the respective view ports to the left eye buffer left buffer and righti buffer. That is, in the case of the stereo mode, the control unit 402 generates one image through the left eye view port and treats it as the left image data, generates one image through the right eye view port, Treat it like this.

6 is a flowchart illustrating an operation flow of a 3D platform when an application including a 3D object is called according to the present invention.

In the middleware (M / W) in the 3D platform, when a control request for an application including a 3D object is received from the basic processing unit 401, the application is called by using a specific API. The application is executed according to the call (S601).

When the called application is executed, the middleware (M / W) analyzes the application through the Java Virtual Machine (JVM). In the context of the present invention, the analysis means extracting a series of data or collecting information for controlling one or more 3D objects included in the application.

The middleware (M / W) extracts 3D objects from the application based on the analysis result and initializes them (S602).

The middleware (M / W) sets an initial view port and a camera angle for the 3D object (s) extracted based on the analysis result (S603).

In step S603, when the view port and the camera are set, the middleware M / W calls the high level API for rendering to add the 3D effect according to the present invention (S604).

The middleware (M / W) identifies a mode for controlling the 3D object extracted through the called high-level API (S605). As described above, the mode includes a mono mode and a 3D mode, and the 3D mode may include a stereoscopic mode and a multi-view mode. For the sake of convenience, the stereoscopic mode will be described as an example in the 3D mode.

If the mode identified by the middleware (M / W) is in the mono mode, it is directly rendered using the view port set in step S603. Alternatively, if the identified mode is the stereoscopic mode, the left view port and the right view port are set based on the set view port with reference to the configuration information of the user, and rendering is performed twice using each set view port .

In more detail, the Java Virtual Machine (JVM) calls a high-level API for rendering to identify the mode selected by the user (S605).

If the mode identified in step S605 is a mono mode, a mono eye view port and a camera angle are set on the basis of the view port and the camera set in step S603 (step S610), and the scene graph (S611).

On the other hand, if the mode identified in step S605 is the stereoscopic mode, the camera angle is set based on the user's configuration information, the left view port is set (S606), and the left A scene graph is generated for the image data (S607).

In the same manner, the camera angle is set based on the user configuration information, the right eye viewport is set (S608), and a scene graph is generated for the right image data generated through the right eye view port according to the set camera angle (S609).

In the above, the scene graph models a 3D object in order to maximize a 3D effect according to an input selected by a user, and controls a view port, a light, a mesh, a texture, do.

Each generated scene graph is finally rendered to have a 2D or 3D effect according to the mode (S612).

After the rendering is completed, control for the application is terminated (S613). The execution of the application is terminated (S614).

When the camera for the 3D object, the left view port, and the right view port are set, the controller 402 controls the generated camera to generate left and right image data for the 3D object through the respective viewports. Here, the control unit 402 may generate the left / right image data through the camera and the left / right view port as it is based on the analysis result for the 3D object. If the user sets the configuration information, Thereby generating left / right image data.

At this time, at least one of the camera angle information about the 3D object, the distance information between the camera and the subject, the size information about the subject or the 3D object, and the resolution information is included in the configuration information or analysis data, for example .

Accordingly, in generating the left image data and the right image data, the controller 402 sets the camera angle information, the distance information, the size information, and the resolution information in the left eye view port and the right eye view port, .

In Fig. 7 (b), the left image data and the right image data generated through the camera and each view port based on the configuration information are shown.

Referring to FIG. 7 (c), the left image data and the right image data generated for one 3D object are rendered in a format for giving a 3D effect.

In Fig. 8 (a), the frames generated in Fig. 7 (c) are mixed in conformity with the 3D format.

In FIG. 8 (b), when the mixed images are formatted according to the frequency of the display module, for example, and then viewed using a device such as a shutter glasses, images for the left eye and images for the right eye are output Lt; / RTI >

In addition, in the present invention, the user does not set such configuration information in advance, but controls the 3D object and receives input of such information. The image processing apparatus directly reports the changed image according to the input of the user, May be provided.

In FIG. 10, there are a variety of methods for expressing the 3D effect. For example, in FIG. 10 (a), three formats are provided for the user to select a desired 3D output format. The first is automatic, the second is stereoscopic, and the last is multi-view image, but the present invention is not limited thereto. For example, when automatic is selected, the image processing apparatus switches directly to the side-by-side format in a format previously set in the image processing apparatus, for example, the stereoscopic method.

Alternatively, if the user selects the stereoscopic image or the multi-view image format in FIG. 10 (a), information on the detailed format in the selected format may be provided as shown in FIG. 10 (b). FIG. 10B shows an example of a UI provided so that a specific detail format can be selected from among the stereo-scopic formats.

As described above, according to the present invention, it is not only possible to easily process the contents or application including the 3D object in a software manner without providing a separate apparatus such as a conventional console or a PC, According to the present invention, the 3D effect can be appropriately adjusted according to the user's taste or the like if the 3D image is viewed manually by a preset format or value. Such a content provides a user's convenience to the image processing apparatus and compatibility with the conventional image processing apparatus.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative.

The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
