Description

A Handheld Terminal Realizing 3D Video Effect

technical field

The utility model relates to a hand-held terminal, in particular to a hand-held terminal for realizing 3D video effect.

Background technique

The principle of 3D video effect is based on the parallax of human eyes. A person's two eyes are about 5 cm apart, and the angles of the two eyes will not be the same when looking at anything except the front. Although the gap is very small, it is transmitted to the brain through the retina, and the brain uses this tiny gap to generate the depth of distance and thus create a three-dimensional effect. According to the above principle, if the same image is used to create two images using the difference in the angle of view of the two eyes, and then let the two eyes have one on each side, and each eye only sees the image on its own side, the brain can produce depth of field through the retina. three-dimensional sense.

With the popularization of 3D video, there have been handheld terminals that play 3D video.
