Description

Stereoscopic image realization system and method thereof

The present invention relates to a stereoscopic image realization system and a method thereof, and more particularly, there is a player for a stereoscopic monitor, but in conjunction with the DDC / CI (Display Data Channel Command Interface E-DDC) capable of determining a stereoscopic monitor. The present invention relates to a stereoscopic image realization system and a method for improving the convenience of a user by improving the convenience and workability of a 3D image by automatically determining a 2D / 3D video output using a protocol.

Generally, there are many ways to implement stereoscopic images, but most of them combine two images for binocular disparity in one storage medium such as one Video Player, DVD (Digital Video Disc / Digital Versatile Disc), Player, and Betacam. In other words, the image quality of the image is reduced to 1/2 of the left and the right of the image, so that it is practically impossible to use in a large-scale display such as a digital theater, and it is manufactured and used in the form of a film.

Betacam is a type of broadcasting equipment, which includes "Digital Betacam Video (NTSC)" and "Analogue BetacamVideo (NTSC)". By using two DVD players, it maintains the high quality of the next-generation video storage media, DVD, The image quality on the right makes it possible to achieve virtually double the image effect on the left and right.

However, even in the case of DVD players produced on the same line, it is difficult to use to display stereoscopic images using binocular disparity that must be displayed at the same time due to the inconsistency of the video views. to be.

In particular, the monitor for displaying the stereoscopic image determines the output method according to the source / environment / user mode. This mode is performed manually and cannot be linked with the video player.

Therefore, in the conventional technology, as the monitor mode is changed, there is a problem that the mode of the stereoscopic video player must also be manually changed.

Accordingly, the present invention has been made in view of the above-described circumstances of the prior art, and an object of the present invention is to provide all the information without the manual conversion of the two functions of the stereoscopic mode (3D) and the existing mode of use (2D). By collecting and analyzing information / type / manufacturing / stereo mode through the DDC / CI protocol, the stereoscopic video player displays the left / right images in synchronization, or implements the left or right images when the stereo mode is not used. The present invention provides a stereoscopic image realization system and a method for improving the workability and increasing the commerciality.

This object is achieved by the present invention, and in accordance with an aspect of the present invention, a stereoscopic image implementing system includes a storage unit for storing image information downloaded or locally stored on a network, and the left / right input from the storage unit. A decoder for analyzing right image information, a left and right image information analyzed by the decoder, and a synchronizing unit for classifying and synchronizing into normal mode and stereoscopic mode according to the output monitor type, and according to the synchronization unit And a rendering unit for dividing the left / right image information into left and right video and outputting the left and right audio.

In this case, it is preferable that the synchronization unit uses a DDC / CI (Display Data Channel / Common Interface) protocol.

According to another aspect of the present invention, a stereoscopic image implementing method includes the steps of retrieving downloaded or locally stored image information, interpreting the retrieved image information, and comparing and analyzing the analyzed image information and outputting the image information. Synchronizing left / right image information when the monitor type is a stereoscopic mode, and reproducing a frame of the synchronized image information.

In this case, when the analyzed image information is compared and analyzed and the output monitor type is a normal mode, the method may further include reproducing left or right image information. The synchronization unit may preferably use a DDC / CI protocol.

According to the configuration and method of the present invention, all the information of the stereoscopic monitor (3D) and the existing mode of use (2D) of the two functions without manual conversion of the information through the DDC / CI protocol information / type Collecting and analyzing / manufacture / stereo mode, the 3D player can show left / right images in sync or implement left or right images when not in stereo mode to enhance user convenience and workability. That effect occurs.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

1 is a schematic configuration diagram of a stereoscopic image implementing system according to an exemplary embodiment of the present invention, and FIG. 2 is a flowchart illustrating a stereoscopic image implementing method according to FIG. 1.

As shown in the figure, the stereoscopic image implementing system according to the present invention, shown by reference numeral 10, includes a storage unit 12 for storing image information downloaded or stored locally on a network, and in the storage unit 12. The decoder unit 14 which analyzes the input left and right image information and the left and right image information analyzed by the decoder 14 are compared and analyzed and classified into a general mode and a stereoscopic mode according to the output monitor type. It includes a synchronization unit 16 to make.

In addition, the system 10 divides the left and right image information into left and right videos according to the synchronization unit 16, and outputs the divided units 18 and 20 to output the left and right audio. (22) is provided.

In other words, the 3D image is received as a local file or a network stream and the left and right images are interpreted to be rendered by the decoder. When the monitor type information is the 3D mode, the left and right images are analyzed through the comparative analysis. Check each frame of the right image.

In this case, the information of the left / right image should be provided exactly in accordance with basic information (Size / Rate / Frame). In video rendering, a role of a window providing a synchronized source and a user option for providing audio are provided. The audio of the left image or the audio of the right image is allocated separately or weighted to one side.

The synchronization unit 16 is controlled by a Display Data Channel / Common Interface (DDC / CI) control unit 24. The control unit 24 uses a DDC / CI protocol. Protocol defined for data exchange.

The reason for using the above protocol in the present invention is that in the past using the old monitor, monitor information such as 1024x768, brightness, saturation, density should be modified in the monitor, but in the case of a monitor supporting the DDC / CI protocol, This is because you can control the resolution, brightness, etc. of the monitor with the mouse.

Referring to Figure 2 the method according to the above configuration of the present invention will be described.

First of all, the image information is downloaded from the network or stored locally in the storage unit 12, and the retrieved image information is interpreted (S10 and S12).

Thereafter, the analyzed image information is compared and analyzed, and when the output monitor type is a stereoscopic mode, left / right image information is synchronized (S14, S16, S18, S20), and the reproduced frame is reproduced. The stereoscopic image is implemented until the end (S22, S24).

At this time, the synchronization uses the DDC / CI protocol, and if the analyzed image information is compared and analyzed, the left or right image information is reproduced (S26, S28, S22).

In other words, it starts like a general video multimedia player, and in order to automatically open left and right stereoscopic images with user's authority in opening a source video, a set of file name rules is required.

The decoder unit 14 of the left and right image information performs a first operation of obtaining frame information using a general integrated codec. Firstly, information of a stereoscopic monitor is obtained from a monitor type.

In the stereo mode of the information of the stereoscopic monitor, the left / right images are checked to synchronize the frames (order / rate).

After that, it is displayed through the frame playback on the screen of one window, and it supports the full screen mode like the general video player to achieve the purpose of the video player. In the monitor type selection, it is also possible to confirm through an event (user's monitor button operation).

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
