If any, the terms "first," "second," etc. are used for distinguishing between technical features only, and should not be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
At present, multimedia files such as videos watched by users are generally in a 2D format, for example, the videos watched by users through video software are generally videos in the 2D format, or the videos watched by users watch teaching videos on a classroom are generally videos in the 2D format, or the advertisements displayed on a street are generally videos in the 2D format.
The applicant found that when the 2D video in the related art is to be converted into a display mode, complex processing is often required to be performed on the whole video file to convert the whole video file into a 3D video, for example, a part of a 3D movie, but not all the video may be converted into the 3D video, and some videos need to keep the viewing characteristics of the 2D video, for example, some variety videos, some teaching videos, and the like, and if the videos are directly converted into the 3D video, the display effect is affected, so that the related art has the problems of single display mode, poor user experience, and the like.
In addition, the applicant has found that viewing two-dimensional objects such as books, newspapers, cell phones, televisions, etc. with eyes in a relatively fixed line of sight is the first major cause of myopia formation, and that viewing two-dimensional objects such as cell phones, computers, books, etc. with eyes in a relatively fixed line of sight is the first major cause of myopia formation, and that long-term close-range planar fixation can lead to inability to adjust the lens for a long period of time, and slow weakening of the contraction and stretching functions of the ciliary muscle of the eye, and the accommodative ability of the lens.
When the lens of our eye is unable to properly adjust the vision distance, a blurred vision, what we say myopia, is presented. The 3D display can enable ciliary muscles of eyes to adjust lenses at any time, so that the eyes can be trained, plane fixation is reduced, and the influence of three-dimensional objects on the eyes is increased. Through 3D display, when the eyes of a user watch three-dimensional things, the user can move in all directions up and down and left and right, and compared with a plane effect, the eye health can be better protected, and the myopia prevention and control effect is achieved. In the related art, most videos are 2D videos, and users watch 2D videos for a long time, so that eyes are injured due to plane fixation, myopia is easy, and a certain myopia hidden trouble is caused.
