Abstract

The present invention is a method of implementing a three-dimensional image, in order to see the conventional three-dimensional image wearing a stereoscopic image dedicated glasses, but the present invention utilizes a stereo method without wearing a stereoscopic image glasses in the left and right two cameras corresponding to human vision It is a method of viewing stereoscopic images on a daily basis by using two monitors for each of the two transmitted signals.
The signals sent to the existing stereoscopic cameras are classified separately and output to the two monitors so that they can be seen with or without glasses. It can also be implemented by screen division method of general TV.

Description

3D display with two way system without glasses}

As a method of implementing a 3D stereoscopic image, a method of realizing a stereoscopic image wearing glasses through a polarization method and a parallax scanning method has been developed and put into practical use.

This method is to wear glasses and there is a glasses-free 3D implementation technology through the parallax scanning method.

The technology for realizing stereoscopic images is that two cameras simultaneously scan or project two screens taken from the eyes of a person with green and red-enhanced screens, and viewers or viewers wear stereoscopic glasses and watch or watch stereoscopic images. do.

Stereo sound is a way to hear stereoscopic realistic sound by sending two microphone input sound through two speakers.

Existing method of stereoscopic image is that when shooting and transmitting or projecting with stereoscopic image-taking camera, all viewers have inconvenience to wear stereoscopic glasses, and if there is no glasses, screen overlaps and unstable flat image It is intended to solve.

In order to solve this problem, the present invention transmits a screen corresponding to left and right vision separately on each screen in parallel with the existing 3D imaging method in which two screens are transmitted on one screen. This method was solved by selecting the 3D image transmission method and watching it with two monitors if there is no glasses.

Broadcasting stations take two general cameras, not 3D stereoscopic cameras, at a distance corresponding to left and right eyesight, and transmit them with two signals as if they are transmitting stereo sound. You can watch.

3D video can be viewed without special glasses or 3D TV, and multi-view and dynamic screen can be selectively viewed using two screens. In particular, multi-mode transmission and 3D can be operated effectively and dynamically in the places where video devices such as electric signboards or karaoke halls are used for a large number of people. In general shooting, if only two cameras are taken at the same time, 3D can be easily implemented in a screen division method.

The present invention implements only one screen in the case of the 3D image device, the viewer has to wear glasses and the inconvenience to see the overlapping blurry screen when there is no glasses when sending out to the 3D screen, the present invention is to solve the sound The stereo method of was applied to the monitor as it is. Two ordinary cameras shoot at the interval of right and left visual acuity and transmit the video signals recorded by each camera, and at home, each monitor uses two monitors, and one monitor uses the left eye of the 3D screen. By selecting and outputting a signal, another monitor selects and outputs a signal from the right eye system so that a stereoscopic image can be viewed without glasses.

The process is described in detail as follows. The conventional 3D stereoscopic image is shown in FIG. 1. With a special stereoscopic image recording camera that requires the green or red polarization of FIG. 1, the image corresponding to the left and right lines of sight is recorded, the screen is scanned on the same screen, and the polarized glasses for filtering colors are used to view the image. As shown in FIG. 1, this method combines images taken by two cameras into a single signal and displays one integrated signal on one screen to filter and see the color of different gazes through glasses to produce a stereoscopic effect.

The present invention allows viewing of a stereoscopic image even when glasses are not present. In order to prevent the glasses from recording signals transmitted by 3D stereoscopic images without glasses, the respective polarized signals are respectively provided through a receiver or a separate signal converter as shown in FIG. When the signal is divided into two screens to be output on two screens, the two screens overlap each other at a certain time and appear as one stereoscopic screen.

3 shows a series of processes for viewing 3D stereoscopic images without glasses on a normal TV.

The camera 301 corresponding to the left eye is photographed using a general camera without polarization. Cameras 302 corresponding to the right eye are also general cameras, and both cameras capture the same image at the same interval as the human eye when capturing the image.

Each photographed image is stored as one signal 303 and transmitted to the broadcasting station 304, which is bundled and transmitted as a stereo signal 305, and each household receives it as a stereo signal 306. The video signal received as a stereo signal in each home is transmitted to two monitors, in which the left camera 307 displays the video taken by the left camera and the right monitor 308 displays the video taken by the right camera.

The viewer sees the monitor without wearing glasses, and the monitor appears to have the same screen displayed on each monitor.

At this time, when the viewer looks at the two screens as if seeing the magic eye, the screen overlaps where the gaze overlaps and a three-dimensional image appears.

Even if the image is not viewed as a stereoscopic image, the screen is not overlapped, so the same image is clearly seen in 2D on two monitors, and when the 3D stereoscopic surface is not seen without blurring, there is no discomfort. If you have two or three monitors and enjoy multiple channels, you will be able to enjoy 3D without any additional burden.

If a broadcasting station takes a picture corresponding to the left and right line of sight and sends the left and right camera signals by dividing the same screen, it will be possible to watch 3D directly from a normal home.
