3D Eyeware Complementary color
Also known as color difference, both common red and blue, red and green and other colored lenses 3D glasses.
Color difference can be called color separation stereoscopic imaging technology, is the use of two different angles on the image were printed in two different colors in the same sub-picture. With the naked eye to watch the words will be vague ghost images, only through the corresponding red and blue and other stereoscopic glasses can see the three-dimensional effect is to color the red and blue filter, red image through the red lens blue through the blue Lens, two eyes to see the different images in the brain overlap showing 3D stereo effect.
The left projection of the screen through the red lens (left eye), shooting off the red pixels automatically restored, resulting in a true color of the screen, when it is through the blue lens (right eye) when most of the filter, leaving only very Dark screen, which is very easy to be ignored by the human brain; the other hand, the right projector to shoot the picture through the blue lens (right eye), shooting away the blue pixel automatically restored, resulting in another angle of the real Color screen, when it passes through the red lens (left eye) when most of the filter, leaving only the dark picture, the human eye is automatically passed to the brain after the filter.
Polarization 3D technology is now widely used in commercial cinema and other high-end applications. In the technical way and the shutter is the same, the difference is passive reception is also known as passive 3D technology, auxiliary equipment, the lower the cost, but the higher requirements of the output device, it is very suitable for commercial cinema, etc. Need to use a lot of places for the audience. Not flash is the use of this principle.
Three-dimensional sense of the main reason is that the left and right eyes to see the different screen, left and right eye position so there will be some differences in the screen.
Shooting three-dimensional image is used when the left and right two lenses. The image of the left lens is then filtered through a transverse polarizer to obtain transversely polarized light, and the image of the right lens is filtered through a vertical polarizer to obtain longitudinal polarized light.
The left and right eyes of the stereoscopic glasses are fitted with a transverse polarizer and a vertical polarizer, respectively. The transverse polarized light can only pass through the transverse polarizer and the longitudinal polarized light can only pass through the longitudinal polarizer. So that the left side of the camera to ensure that things can only enter the left eye, the right camera to shoot things can only enter the right eye, so when the three-dimensional
Also known as active shutter 3D glasses, shutter 3D technology for home users can provide high-quality 3D display, the implementation of this technology requires a proactive LCD shutter glasses, alternating left and right eye to see the image so that Your brain will be two images into one to achieve, resulting in a single image of the 3D depth sense.
According to the human eye on the image frequency refresh time to achieve, by improving the screen's rapid refresh rate (at least to reach 120Hz) left eye and right eye of the 60Hz fast refresh the image will make people do not produce jitter , And keep the same number of frames as the 2D video, the two eyes of the viewer see the different screens that are quickly switched and create illusions in the brain to see the stereoscopic image.
