Description

3D solid image implementation apparatus using double scanning method and 3D solid image system comprise of the same}

The present invention relates to an image processing apparatus, and more particularly, to an apparatus for processing a 3D stereoscopic image.

Three-dimensional stereoscopic game is a fantastic three-dimensional stereoscopic image that can be seen in three-dimensional theaters such as Lotte World, Seoul Land, and Daejeon Expo Park. It means the distance between the screen elements and the virtual reality image that protrudes out of the screen are applied to the game. do.

The realization of this three-dimensional stereoscopic image is based on the fact that humans have two eyes, and the principle that humans perceive objects in three dimensions is horizontally spaced apart (approximately 7.5 cm-adults, 5 cm-children). It is possible by two human eyes receiving objects through different retinas from different angles, and then synthesizing the two images by electric signals. Therefore, the background of the game and the characters (characters) were produced by the three-dimensional technique and solidified, so the two images obtained by the visual difference having the difference of two eyes' angle are separated into the left and right eyes. The game can be realized.

Existing peripheral technologies that make this possible are LCD Shutter glasses that can deliver images to the retina simultaneously to the left and right eyes and generate another angle image in real time from the planar image. The main technology is spread in the form of computer software driver, but the limitation of the technology is that it supports only a graphics card equipped with a specific chipset and a limited API (3D game production method such as 3dfx Glide, MS D3D, Quake OpenGL, etc.). Marketability, etc.).

In addition, in 3D stereoscopic images, when the left and right images are not completely separated, a ghost-like image occurs when the opposite image is seen by both eyes. It often occurs when the rate is low. In addition, when the liquid crystal electronic glasses are operated at a low vertical refresh rate, flickering occurs when the opening and closing operation of the liquid crystal is seen as interference of light.

The technical problem to be achieved by the present invention is a three-dimensional stereoscopic image realization apparatus using a dual-scan method that can eliminate the ghosting and screen flickering by realizing the left, right image by the dual scanning method and a three-dimensional device having the same In providing a stereoscopic image system.

Hereinafter, the operation of the present invention will be described with reference to the drawings.

The block diagram shown in FIG. 1 includes a shaping unit 110, a first image processing unit 120, a second image processing unit 130, and a sequential output unit 140.

The shaping unit 110 vertically compresses each of the left and right image signals obtained by a visual difference having a difference corresponding to the angles of two eyes, and shapes one image signal separated into upper and lower ends.

The first image processor 120 modifies the image signal outputted from the shaping unit and expands only the image signal of the upper side downward based on a boundary line separating the upper and lower ends.

The second image processor 130 modifies the image of the lower end unprocessed from the first image processor 120 upward.

The sequential output unit 140 sequentially outputs an upper image signal processed by the first image processor and a lower image signal processed by the second image processor.

Figure 2 shows a three-dimensional stereoscopic image system having a three-dimensional stereoscopic image implementing apparatus using a dual scanning method according to a preferred embodiment of the present invention.

The system shown in FIG. 2 includes a computer body 210, a 3D stereoscopic image forming apparatus 220, a monitor 230, and a liquid crystal electronic glasses 240.

Unlike the analog, the computer main body 210 includes an image processor for generating a single image signal at the upper and lower sides by compressing the left and right images using a principle that minimizes image loss in a compressed state. The upper and lower images generated by the processing unit output one video signal through the VGA card.

FIG. 3A illustrates an embodiment of a 3D image output from a video card of the computer body 210.

The 3D stereoscopic image implementing apparatus 220 receives the image as shown in FIG. 3A output through the VGA card, and formats the upper and lower images. The upper and lower images are clearly separated from the horizontal boundary line (the black horizontal boundary line). The upper image L is vertically stretched downward by the first image processor 120, and the lower image R is the second image. The processor 130 vertically stretches upward.

Then, the extended upper image (L) is scanned on the monitor 230, and then the lower image (R) is sequentially scanned.

At this time, even if the signal output from the VGA card is a horizontal frequency of 60HZ, the monitor 230 doubles to 120HZ to double-scan to facilitate setting of the monitor 230, and the liquid crystal electronic glasses (at 120Hz) (1/120 seconds). 240) open and close.

The liquid crystal electronic glasses 240 receives the upper image (L) signal and the lower image (R) signal sequentially output from the 3D stereoscopic image display device 220 in a manner opposite to that input to the monitor 230. The 3D stereoscopic image displayed at 230 is viewed.

3B illustrates a 3D stereoscopic image implemented by the apparatus for implementing 3D stereoscopic image using the dual scanning method according to the present invention.

Therefore, the present invention recognizes the basic value of the monitor setting after receiving the video signal to detect the boundary and "double scanning" the picture of the upper and lower, and control the liquid crystal electronic glasses to synchronize the timing of the double scan ( The device manufactured by this technology is made of pass-through terminal that loop-throughs the output of VGA card.
