Stereo imaging method and 3D control terminal

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...

AI Technical Summary

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
