Product Description
Use 3D glasses in the cinema and technology Descriptions:
Screen requirements:
The white screen means the ordinary white screen , the use of high-gain white screen score can be increased 1-2 minutes. In addition to the main metal screen RealD (not rule the use of cinema as the cost of ordinary white screen), and others begin with an ordinary white screen and the internal high-gain white screen-based, the most widely used stand-alone XPAN-D and Dolby 3D More is mainly ordinary white screen.
MasterImage and Dolby 3D is referring to stand-alone system.
Dolby 3D including Dual 3D, Polar double 3D, RealD double 3D, MasterImage double 3D and several such double 3D (Barco made the projector, the so-called double Barco only means projection equipment, but also needs 3D glasses points technology), are circularly polarized, the effect is similar, but glasses are different. The most obvious difference between double machine and the single is that there are two video screening rooms behind the window (the back can see.)
Introduction to 3D technology:
We all know how to focus on 3D projection images of two separate, but the process is generally divided into two separate steps. The first step is to separate the left and right eye images projected on the screen, the second step is to left and right eye images through the glasses were received.
Projection is the best way to separate the two projectors projecting left and right eye images respectively (the so-called dual-3D), this is the most direct and effective ,there is no lose of brightness, contrast, saturation, resolution. Dual 3D, including IMAX 3D ,they all do like this.
Sony 4K projector 3D system is a single two-mirror, respectively, two 2K ??projection screens, in essence, is the same with the dual-3D
Two-machine system use two projector ,it’s so expensive that the use is very little.
Other methods are single alternating 3 octave time difference, that is, continuous switching the projector projecting left and right eye images. This will directly lead to loss of brightness at the same time prone to Ye Ying. Such systems require either the lens or the spectacles at the synchronous device. Once you use synchronous devices, probably because of improper synchronization occurs errors left and right eye image corresponding to double vision.
