I'm going to buy an 3D glasses in the right and left format, a 3D video, and how to get to the cinema 10How about an ordinary screen showing a 3D movie in the left and right?I'm going to buy an 3D glasses in the right and left format. I got a 3D video. How is it different from the movie theater? This is two pictures. The vertical line in the middle makes two copies of the video. How does the movie theater seem to overlap? Then I'll buy a 3D glasses in the right and left format, but can I see the effect? Around the format of 3D glasses, you can see those formats of 3D video?
I think it's better not to buy it. I bought a pair, and I had to debug it. It was a hassle. I either watched 2D at home or went to the cinema to see 3D
People's vision is able to distinguish between the far and near, is the gap between the two eyes. The eyes of the people apart about 5 cm, two eyes in addition to the front of the front, to see anything, the two angles are not the same. Although the gap is very small, but the retinal to the brain, the brain with the small gap, produce distance depth, so as to produce stereoscopic effect. Although an eye can see objects, but the distance between objects is not easy to distinguish.
According to this principle, if the same scene, create two images with two eyes from the perspective of the gap, and then let the two eyes, one on each side, each side to see their images through the retina can cause the brain to produce three-dimensional depth of field. A variety of three-dimensional presentation technology, but also the use of this principle, we call it the principle of polarization".In the optical 3D technology, we can subdivide the three main types: color type, passive polarization, active shutter type, which is commonly referred to as the color method, optical method and time division method.Color difference 3D technology, English Anaglyphic 3D, with the use of passive red - Blue (or red - green, red - green) color 3D glasses. This technology has the longest history, imaging principle is simple, the cost is very low, only a few dollars for the cost of glasses, but the effect is the worst picture 3D. The color difference 3D is used to separate the spectral information from the rotating filter wheel, and the screen is filtered by the filter with different colors, so that a picture can produce two images, and each person can see different images. This method is easy to make the edge of the screen color.Due to poor effect, color 3D technology is not widely used.
