Problems solved by technology

However, the brightness of the screen using this technology is low
[0005] In addition, this technology cannot be well applied in some large screens, because the parallax is not enough to cope with the large screen, resulting in afterimages outside a certain range of line of sight

Embodiment Construction

[0019] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0020] The most critical idea of ​​the present invention is: compare the color tolerance of the 3D video in the left and right formats, if it exceeds a residual image coefficient, replace the corresponding area of ​​one side of the picture with the area of ​​the other side of the picture, so that the eyes can see this area as Non-3D, the afterimage in this area is eliminated.

[0021] Please refer to figure 1 Embodiment 1 of the present invention provides a video afterimage optimization method for a light barrier type 3D display device, including:

[0022] S1: Obtain 3D video and decode it frame by frame to generate left-eye material and right-eye material;

[0023] S2: Compare the color tolerance of the picture pixels in the left-eye material and the right-ey...

Abstract

The invention discloses a video ghosting optimization method and system of a parallax barrier 3D display device. The method comprises following steps of obtaining a 3D video; decoding frame by frame, thus generating left eye materials and right eye materials; comparing the color tolerances of the image pixels in the left eye materials and right eye materials one by one; recording coordinates of target pixels; obtaining regions formed by the target pixels; and replacing the regions corresponding to the other eye materials, thus optimizing the ghosting. Through adoption of the mode, the ghosting produced when the parallax barrier 3D display device is used for watching the video is reduced; and the dizziness and discomfort are reduced.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and system for optimizing video afterimages of a light barrier type 3D display device. Background technique [0002] Light barrier 3D technology is also called parallax barrier or parallax barrier technology. Its principle is similar to that of polarized 3D. It was successfully researched by engineers from Sharp's European laboratories for more than ten years. Light barrier 3D products are compatible with existing LCD liquid crystal technology, so they have advantages in mass production and cost, but the image resolution and brightness of products using this technology will decrease. The realization method of light barrier 3D technology is to use a switch liquid crystal screen, polarizing film and polymer liquid crystal layer, and use the liquid crystal layer and polarizing film to produce a series of vertical stripes with a direction of 90°.
