Description

Stereoscopic Multivision System {THE MULTI-VISION SYSTEM FOR STEREOSCOPIC IMAGE}

The present invention relates to a stereoscopic image display, and more particularly, to a stereoscopic image multivision system.

As display devices have developed, various forms of stereoscopic displays have been developed. In general, stereoscopic images are formed by synthesizing the left and right images recognized by the observer in the head by allowing different images to be recognized by the observer's left and right eyes.

Therefore, in order to produce a stereoscopic image, a device capable of displaying different images in the left and right eyes is required, and the apparatus includes stereoscopic glasses. The stereoscopic eyeglasses use a linear polarization method that separates left and right eye images so that left and right eyes are separately recognized.

However, the above method has a disadvantage in that the user must recognize the stereoscopic image by wearing glasses.

Therefore, recently, a device for recognizing stereoscopic images without wearing glasses has been developed. The device implements a three-dimensional system mainly by combining a device for separating the directional image to a flat panel display device such as LCD or PDP. Such a three-dimensional system is a lenticular method using a lenticular lens sheet, a parallax barrier method using a slit array sheet, and a micro according to a device for separating images for each direction. An integrated photography method using a lens array sheet and a holography method using an interference phenomenon can be classified into various autostereoscopy methods.

A general multivision system is a system for enlarging or reducing a single image and outputting it to a screen. The multivision system is connected to a plurality of image output means to form a multivision system, and simultaneously or selectively to a plurality of image output means. Is a system for outputting. Such a multi-vision system is installed in front of an exhibition hall or a predetermined event hall, and is used for the purpose of advertising by outputting an image required for the exhibition or event.

Korean Patent Laid-Open Publication No. 2004-62724 (name: multivision system, application number 2003-224) is proposed as a conventional technology for a multivision system.

In the prior art, an image signal supply unit 100 for supplying an image signal and at least one image display device are serially connected to each other to form a matrix, and receive an image signal from the image signal supply unit 100. It consists of a multi-vision unit 200 for capturing only the predetermined area and display on the video display device.

Each of the image display devices 201a to 201c, 202a to 202c, and 203a to 203c constituting the multi vision unit 200 allows an image signal input through the image signal input unit 211 to be input to the corresponding image display device. At the same time, the splitter 212 for controlling the output to the outside through the signal output unit 221, the microcomputer 213 for outputting a control signal according to the user's setting, and the splitter (according to the control signal of the microcomputer 213) The image signal output from 212 processes only the video signal of a predetermined area to be displayed, and captures only the scaler 213a built into the microcomputer 213 and only an image of a certain area of the scaler 213a. A memory (EEPROM) 215 for storing position information so that it can be scaled, a frame buffer memory 214 for storing image signals processed by the scaler 213a on a frame basis, and the scaler 213a The LCD module driving unit 216 for outputting a driving signal to the LCD module 217 is configured to be displayed on the LCD module 217 to be output from the video signal.

Each of the display devices 201b, 201c, 202a to 202c, and 203a to 203c performs the same operation as the image display device 201a, so that the image display devices 201a to 201c, 202a to 202c and 203a to 203c are all the same. Video signal is received.

Hereinafter, the operations of the video display devices 201a are different because only the capture area of the input video signal is different and the video signal processing is the same. I will explain only.

First, when an image signal is input through the divider 212, only the image signal corresponding to the preset position information in the memory 215 may be displayed according to the control signal of the microcomputer 213. 213a) captures and processes the signal into a displayable signal and outputs the same.

In this case, since the scaler 213a includes a zoom function, the size of the image is increased by enlarging or reducing the image signals displayed through the plurality of image display devices 201a to 201c, 202a to 202c, and 203a to 203c. May be arbitrarily adjusted.

Accordingly, the LCD module driver 216 outputs the driving signal to the LCD module 217 so that the image of the corresponding area is displayed on the LCD module 217 that receives the image signal output from the scaler 213a.

However, the conventional technology has a problem in that a stereoscopic image is not displayed when a stereoscopic image is input since a general LCD panel is applied.

It is assumed that the composition of the LCD will be described.

1 is a block diagram of a first embodiment of the present invention, as shown therein, the multi-vision unit 130 including eight stereoscopic image display apparatuses 131 to 138, and left and right images of a stereoscopic image, respectively. The multi-vision unit 130 divides the image supply unit 110 for supplying and the left and right images to correspond to a preset display form, adjusts the image to a predetermined size, and synthesizes the synthesized partial stereoscopic image. The stereoscopic image processing unit 120 is provided to the stereoscopic image display device.

As illustrated in FIG. 2, the stereoscopic image processor 120 includes a setting value storage unit 140 for storing coordinate setting values corresponding to a display form, and left and right images Li with reference to the coordinate setting values.

And it comprises a video output unit 129 for outputting the (131-138).

The image supply unit 110 is configured of an image reproducing apparatus such as a computer, a DVD player, or the like.

Referring to the operation and effect of the embodiment of the present invention configured as described in detail as follows.

The image supply unit 110 inputs each of the left and right images Li (Ri) of the stereoscopic image to the stereoscopic image processing unit 120.

At this time, the stereoscopic image processing unit 120 refers to the coordinate setting values corresponding to the respective stereoscopic image display devices 131 to 138 stored by the image divider 121 and 122 in the setting value storage unit 140. The right image Li (Ri) is divided into left and right partial images LPi1 to LPi8 (RPi1 to RPi8). For example, when the left and right images as shown in FIG. 9 (a) are input, the left and right partial images are divided as shown in FIG. 9 (b).

Each of the left and right partial images LPi1 to LPi8 (RPi1 to RPi8) is stored in the frame buffers 125 and 126 for a predetermined time and is supplied to the scalers 123 and 124 for each of the left and right partial images. .

That is, when the left and right partial images LPi1 and RPi1 are taken as an example, the left partial image LPi1 is enlarged or reduced to be processed according to the resolution of the stereoscopic image display device 131 on the scaler 123 and the right. The partial image RPi1 is scaled to fit the resolution of the stereoscopic image display device 131 by the scaler 124 and then output to the image synthesizer 127. Subsequently, the left and right partial images LPi2 and RPi2 are processed by the scalers 123 and 124 and then output to the image synthesizer 127. The process is repeatedly performed for the left and right partial images LPi3 to LPi8 and RPi3 to RPi8.

In this case, the image synthesizer 127 synthesizes the left and right partial images input from the scalers 123 and 124 and sequentially stores the partial stereoscopic images Pi1 to Pi8 in the frame buffer 128. Here, generating the stereoscopic image by scaling the left and right partial images and then synthesizing the left and right partial images is to prevent an image distortion or degradation from occurring when the stereoscopic image itself is scaled.

Accordingly, the image output unit 129 provides each of the stereoscopic images Pi1 to Pi8 stored in the frame buffer 128 to each of the stereoscopic image display devices 131 to 138 provided in the multivision unit 130. do.

Accordingly, a stereoscopic image is displayed on each of the stereoscopic image display devices 131 to 138 provided in the multi-vision unit 130, and the stereoscopic images are combined to display one stereoscopic image.

However, as described in the first embodiment of FIG. 1, when the left and right images of the stereoscopic images are not supplied, but the stereoscopic images are synthesized by combining the left and right images, the configuration of the first embodiment is normally stereoscopic. Since the image may not be displayed, the second embodiment is provided to improve the image.

The configuration of the system of the second embodiment of the present invention is the same as that of FIG. 1 of the first embodiment. However, when a stereoscopic image is supplied from the image supply unit 110, the stereoscopic image processor divides the stereoscopic image into left and right images (Li) (Ri) and divides the stereoscopic image to correspond to a preset display form for each of the left and right images. Each of the divided left and right images LPi1 to LPi8 (RPi1 to RPi8) is adjusted to a predetermined size and synthesized, and the synthesized partial stereoscopic images Pi1 to Pi8 are provided in the multivision unit 130.

Frame buffers 155 and 156, which store RPi8 and provide them to the scalers 153 and 154, respectively, and the left and right partial images of the adjusted size are synthesized to obtain a partial stereoscopic image (Pi1 to Pi8). Image synthesizer 157 for generating a video signal) and a frame buffer 158 for storing the partial stereoscopic images Pi1 to Pi8 for a predetermined time. And it comprises a video output unit 159 for outputting the stereoscopic image part (Pi1 ~ Pi8), each of the stereoscopic image display device (131-138) each forming a multivision 130.

The second embodiment of the present invention configured as described above is configured except that the image supply unit 110 supplies a stereoscopic image obtained by synthesizing the left and right images, and separates the stereoscopic image into left and right images. The operation of the element is the same as in the first embodiment. Therefore, only the different parts from the first embodiment will be described in detail.

That is, when a stereoscopic image is input, it is divided into left and right images as shown in FIG. 9 (a) and divided into left and right partial images as shown in FIG. 9 (b).

Accordingly, the scalers 153 and 154 repeat the operation of adjusting the size of each of the left and right partial images by referring to the display setting values stored in the setting value storage 140.

In this case, when the image synthesizer 157 synthesizes the left and right partial images input from the scalers 153 and 154 and sequentially stores the partial stereoscopic images Pi1 to Pi8 in the frame buffer 158, the image output unit 159 Each of the partial stereoscopic images Pi1 to Pi8 stored in the frame buffer 158 is provided to each of the stereoscopic image display devices 131 to 138 provided in the multivision unit 130.

Accordingly, a stereoscopic image is displayed on each of the stereoscopic image display devices 131 to 138 provided in the multi-vision unit 130, and the stereoscopic images are combined to display one stereoscopic image.

However, as can be seen from the configuration of FIG. 3 described above, the stereoscopic image processing unit according to the second embodiment combines the image separator 150 with the configuration of the stereoscopic image processing unit 120 shown in the first exemplary embodiment of FIG. .

Accordingly, when the image separator 150 is selectively operated according to whether the stereoscopic image is input or the left and right images of the stereoscopic image, the first and second embodiments may be configured as one embodiment. Can be.

In this case, the stereoscopic image processing units 231 to 238 respectively provided in the stereoscopic image display apparatuses 221 to 228 differ only in the left and right partial images LPi and RPi selected from the left and right images Li and Ri. Since the entire operation is the same, only the operation of the stereoscopic image processing unit 231 included in the stereoscopic image display apparatus 221 will be described.

That is, when the left and right images Li (Ri) are input, the stereoscopic image processing unit 231 refers to the display coordinate setting values stored in the setting value storage unit 240 by the image selector 241 and 242. The corresponding left and right partial images LPi and RPi are selected from the right image Li and Ri, and the left and right partial images LPi and RPi are delayed by a predetermined time in the frame buffers 245 and 246. And are supplied to the scalers 243 and 244 for each of the left and right partial images.
