How 3-D Glasses Work

Although it was thought that the 1950s was the ten years of 3D movies, the first feature film "The power of love" was made in 1922. Since then, the use of 3D technology in movie theaters and television is becoming mainstream. Whether you use them for big screen or home TV, however, you must admit that 3D glasses are very cool.

They show movies and TV shows you are looking like 3D scenes that are going on in front of you. When an object is stretching out of the screen and managing your direction and an eerie character reaching for grabbing you, you will feel a part of the action just by wearing 3D glasses. Thinking that they have such high entertainment value, you will be amazed at how simple 3D glasses are wonderful.

In this article, I will introduce the two most popular 3D glasses currently in use. But first let's look at the so-called binocular vision.

This movie was released on the US DVD and Blu-ray on July 21, 2009 by Universal Studios Home Entertainment. The 3D version comes with 4 pairs of 3D glasses - in particular green - magenta stereo images. Coraline was released on British DVD and Blu-ray on October 12, 2009. The 3D version of the movie has also been released in the 2 - Disc collection. DVD was released in the first week with sales of 1,036,845 and sales of over 19 million dollars. Total sales exceeded 2.6 million units, sales exceeded $ 45 million. In 2011, a two-piece Blu-ray 3D set including a stereoscopic 3D image of a first disc and a stereoscopic 3D image was released.

The 1950s were most often regarded as 10-year 3D movies, but the first stereoscopic film "The Power of Love" was produced in 1922. Since then, the use of 3D glasses technology at movie theaters and televisions has been out of the mainstream epidemic. However, we must admit that 3D glasses are very cool, both for large screens and home TVs. They show movies and TV shows you are looking like 3D scenes that are going on in front of you. When an object is stretching out of the screen and managing your direction and an eerie character reaching for grabbing you, you will feel a part of the action just by wearing 3D glasses. Thinking that they have such high entertainment value, you will be amazed at how simple 3D glasses are wonderful.

Many efforts have been paid in "3D unmanned glasses without glasses" (in particular, the Soviet Union who have used vertical slats for many years), but viewers have taken out of two special eyeglasses You must wear one of them. . In the initial stereo photo system, one lens of the glasses was red and the other was a green lens (after blue). Images on the screen without glasses are displayed as two slightly offset images. One is a red line and the other is green. Each lens of the eyeglasses darkens the opposite color so each eye can see only the images used for it.

The reason for wearing 3D glasses in a movie theater is to see various images like View - Master. Two images are actually displayed on the screen and one image enters one eye with eyeglasses and the other eye enters the other eye. There are two general systems that can do this: Red / Green or Red / Blue system is currently mainly used for TV's 3D effect and is used in many old 3D movies. In this system, two images are displayed on the screen. One is red and the other is blue (or green). Filters for glasses have only one image in each eye, the rest are your brain. If you use colors to separate colors, you can not actually create color movies, so the image quality is not as good as the polarization system.
