3D movies to see a long time will feel dry eyes, uncomfortable, 3D film will affect vision?

3D movies to see a long time will feel dry eyes, uncomfortable, 3D film will affect vision?

Answer:

1 red and blue: This is the first appearance, the most primary of a 3D stereo imaging technology will be divided into two different colorsThe images are printed in two different colors in the same picture. So the video is on the show aloneThe naked eye can only see the blurred ghosting, and through the corresponding red and blue glasses can see three-dimensionalThe effect of red and blue glasses, for example, the red lens can only be resolved in addition to the red outside the scene (red lenses, background colorFor red so the red in the film is ignored, the blue lens can only distinguish the blue (blue)The blue color of the film is ignored, and the two eyes see different images in the brainOverlap presents a three-dimensional effect of 3D.
2 polarized stereo: it is to observe the scenery of the human eye, the use of two parallel placement of the film camera, respectively, on behalf of the left and right eye, simultaneous shooting of two horizontal parallax of the film screen. When the utility model is projected, two film films are respectively arranged in the left and right film projectors, and the front side of the projection lens is respectively provided with a polarizing mirror with a pair of polarization axes of two degrees which are mutually arranged into a degree of 90 degrees. Two projectors need to be synchronized, and the screen will be placed on the metal screen, the formation of the left image like a double shadow. When people wear special polarized glasses, because the polarization of left and right two polarizing mirror axis perpendicular to each other, and consistent with the polarization projection lens before the axis; the audience in the left eye can only see the image, the right eye can only see like aggregation through the eyes, the left and right image on the retina and stack the visual effect, generated by a three-dimensional brain. Show a picture of a coherent three-dimensional, so that the audience feel the wind blowing, or into the deep recesses of the screen. Can produce a strong sense of "immersive".Polarized stereo benefits and deficiencies: 3D image effect is very good, brightness and color performance are close to the original 2D, recommended. Light was the main drawback is that must be shown in a metal screen high gain, which makes the screen is not compatible with the conventional theater; should be added before eliminating ghost DCDM (ghosts) of DCP in the production process, resulting in not easily compatible with unified dcdm. In the actual viewing, near the edge of the screen image is prone to blur.
3 shutter stereo: time division method is NVIDIA, now the main push of an application, the need to monitor and 3D glasses to achieve the three-dimensional effect of 3D. Time division method used in the construction of stereo glasses is the most complex, the two lenses are electronically controlled, according to the output of the display state switching. The lens transparent, opaque switch makes the human eye can only see the corresponding picture (transparent mode), the principle is the use of liquid crystal glasses can take the initiative to close, through the wireless signal control switch to achieve high speed liquid crystal glasses, the left and the right eye to see different content, to achieve three-dimensional imaging effect.The advantages and disadvantages of time division method: because of the use of Nuvision manufacturing technology, imaging effect is good, but the cost of glasses is very high. The price is around 1000 yuan. Need to use batteries to make glasses too heavy. Therefore, it is necessary to go to the cinema to pay the deposit glasses; in addition to the refresh rate was reduced to half the original, so the brightness of the screen to lose 50%, unless the use of double screen to make up.Principle incompetent, a look is paste
