Integrated stereo image display device {An unified stereo image display device}

The present invention relates to an integrated stereoscopic image device using stereoscopic glasses and program technology using a general monitor and a PC.

[Document 1] Republic of Korea Invention Utility Model 20-0187207 Computer Stereoscopic Image Conversion Device and Wireless Stereo Shutter Glasses

A technology for viewing stereoscopic images using a general computer, a general monitor, and stereoscopic glasses has been released.

[Document 1] has a disadvantage in that it is not applied to the polarization method because it is applied only to the Line-Blanking method.

In the case of the polarization method, the left and right images are frequently changed, causing many problems.

In the stereoscopic viewing through a general monitor, the brightness of the stereoscopic image is attenuated by more than 50% due to the influence of the control circuit connected with the attenuation of the brightness of the polarized glasses by the liquid crystal.

In addition, in the stereoscopic viewing apparatus, a management technology on the screen is required so that a customer can conveniently view a stereoscopic image for a stereoscopic still image and a stereoscopic video.

In order to solve the above problems, a stereoscopic control circuit that can be applied to polarized glasses in addition to the Line-Blanking (liquid crystal shutter glass) system, and stereoscopic still image view, stereoscopic video view, left and right reverse view on one screen with the stereoscopic viewing device All-in-one stereoscopic viewing device with features that make up video control and adjustment of stereoscopic images

According to the present invention, not only the liquid crystal shutter glass but also polarized glasses are applied and brightness is compensated, and the stereoscopic viewing device has the effect of processing stereoscopic still image and moving image and reverse image and stereoscopic image on one screen.

The present invention is provided with a PC, a display device, a stereoscopic glasses, a stereoscopic image adjustment controller and a viewing device equipped with a stereoscopic image management module which is a program for managing stereoscopic images. A signal controller for synchronizing the video signal with the liquid crystal glasses and monitor

The composition of RGB signal amplifier as a means for compensating for signal loss and brightness loss of stereoscopic images

The present invention relates to an integrated stereoscopic image device for viewing and adjusting stereoscopic images of the stereoscopic viewing device.

When explaining the present invention in more detail as follows.

1) 3D image switching circuit of liquid crystal shutter glass or active polarized glasses and monitor: It consists mainly of hardware control device on the graphic card output port, so that RGB signal, H Sync (horizontal sync frequency) and V Sync (vertical sync frequency) are used on PC graphics card. After amplifying this signal, the central processor analyzes the left and right eye signals according to the sync signal by matching the stereoscopic image signal from the differential amplifier to the sync signal for sure logic. It serves to send.

In this case, the line-blanking method detects odd and even lines and sends a sync signal to the liquid crystal shutter glass glasses. In the polarization method, it detects vertical separation, left and right separation, and page frame signals. It is possible to realize polarization type and line-blanking method through monitor by sending sync signal to right and left eyes.

2) Stereoscopic attenuation image compensating function: Attenuation occurs by installing additional circuit in general PC output port, and attenuation of more than 50% of brightness caused by liquid crystal effect occurs due to the characteristic of stereoscopic image. In other words, the RGB signal from the PC output port is output at the rated voltage of 0.7V and falls below 0.5V due to the influence of the controller circuit. The RGB signal is amplified to 1V level to compensate for this and compensate for stereoscopic images and polarized glasses. This allows the brightness and contrast to be restored to their original state without the problem of raising the voltage on the monitor.

3) stereoscopic still image, stereoscopic video and stereoscopic image control on one screen of the stereoscopic viewing device: in the case of stereoscopic image, the left and right images are arranged through a stereoscopic image viewing program and line blanking of glasses according to With polarized glasses, customers see stereoscopic images through the synthesis of left and right images. To view these stereoscopic images, 2D stereoscopic image viewing programs and 3D stereoscopic image viewing programs are made in accordance with line blanking or polarized light respectively. As a result, the customer installed and applied the program individually according to the above situation.

So, in order to eliminate this inconvenience, if you put the players who can operate all of the above programs on one screen and press 2D stereoscopic view, you can use line blanking (field separation) or polarization (left and right separation, vertical separation, page frame) method. 3D still image viewing function through the configuration to export two images through the program on the viewer program to view each still image

If you press the 3D stereoscopic video view, you can apply the existing video player such as Gom TV and export the two images according to the sync of the stereoscopic glasses sink signal.

In contrast to the case of the passive polarized glasses and stereoscopic images, the left and right stereo images are reversed when the image is input, and the left and right images are changed through the reverse switch. Reverse video control function is configured to reverse the order.

3D image depth and protrusion adjustment function are configured by adjusting resolution setting, 3D image format setting and distance of left and right images connected to each graphic card.
