Problems solved by technology

[0005] 1. Limited to only support NVIDIA graphics cards and 3D VISION drivers;
[0006] 2. Limited to only support Nvidia's own shutter glasses, the price threshold is high;
[0007] 3. The 3D vision driver has stopped updating, and NVIDIA will no longer have 3d vision in the future
[0008] At the same time, when using a 120Hz display, different backlight control methods are required to cover the transient state in the middle, so as to prevent the left eye from seeing the image of the right eye or the right eye from seeing the image of the left eye. The order of sending signals in 3D is LRLR, so the switching frequency of 3D glasses is 60Hz, which is also the switching frequency supported by most glasses now, and the above-mentioned stereoscopic imaging method, if paired with a display with a refresh rate higher than 120Hz, It cannot be adapted to 60Hz 3D glasses

Embodiment 1

[0061] Please refer to figure 1 with Figure 4 , Embodiment 1 of the present invention is:

[0062] Stereoscopic imaging methods include active glasses and passive glasses in the current technology. Since the present invention involves active glasses, the stereoscopic imaging technology of active glasses will be briefly described below. See the background art for its principle. Because this technology alternately displays the images of the left eye and the right eye on the screen, in order to reduce the flickering feeling, this kind of display requires a higher refresh rate, such as the existing 120HZ display, so that the left and right eyes can get 60Hz respectively , due to the residual effect of the LCD, the actual image on the monitor is updated to image 3 As shown, so different backlight control methods are adopted at a refresh rate of 120Hz, specifically, local control of the backlight and an increase of 30%-40% of Vtotal (vertical synchronization period). At the sam...

Embodiment 2

[0077] Please refer to Figure 5 , the second embodiment of the present invention is:

[0078] The 3D control terminal 1 includes a memory 3, a processor 2, and a computer program stored in the memory 3 and operable on the processor 2. When the processor 2 executes the computer program, the steps of the first embodiment above are realized.

[0079] In this embodiment, the 3D control terminal 1 refers to a display with a built-in 3D control board, and the display includes a backlight part. In other equivalent embodiments, the 3D control terminal 1 may be a 3D control panel. In this case, turning off the backlight and turning on the backlight in the above steps correspond to sending a control signal for turning off the backlight and a control signal for turning on the backlight.

[0080] To sum up, the stereoscopic imaging method and 3D control terminal provided by the present invention, in the case of using a high refresh rate of 240Hz, switch screens in the order of LLRR sign...

Abstract

The invention discloses a stereo imaging method and a 3D control terminal. The method comprises the steps of carrying out the image switching according to a 240Hz refresh rate and an LLRR signal sequence, L representing a left eye image, and R representing a right eye image, turning off the backlight at the first L and the first R, and turning on the backlight at the second L and the second R, and synchronously outputting a lens switching signal that only the left eye is turned on when the two L are located and only the right eye is turned on when the two R are located to the 3D glasses so as to realize stereo imaging. Under the condition that the display requirement of high refresh rate is met, the method is suitable for the 60Hz 3D glasses, and ghost shadows cannot be seen.

Description

technical field [0001] The invention relates to the technical field of stereoscopic imaging, in particular to a stereoscopic imaging method and a 3D control terminal. Background technique [0002] NVIDIA's 3D Vision technology uses special glasses to cover the left and right eyes of the person respectively, so that the two eyes can see two images with different angles. screen, such as figure 2 As shown, that is, when the screen displays the image for the left eye, the right lens turns black. After switching once, the left lens becomes black when the screen displays the image for the right eye. In this way, a quick switch ensures that there is a slight difference between the left and right eyes. Image. The simple understanding is that NVIDIA allows GeForce graphics card to calculate two different images for each frame when calculating the game (the movie effect is realized through dual cameras), display them on the monitor, and then let the left and right eyes see them resp...
