How to build a full range of 3D HD home theater system
High quality 3D image playback must have the following factors:1, after wearing 3D glasses, the brightness and color of the image has not changed significantly, the image play smooth, natural, clear picture, and wearing 3D glasses should feel comfortable.Play 2, 3D image is taken to the left and right two signals were broadcast, and by wearing glasses, the eyes can see about two image signal respectively, but to ensure the signal to the left to see the left eye, right eye to see the right signal, otherwise, the two images into the same signal at the same time the eyes will appear, crosstalk, ghosting phenomenon, image rendering 3D texture.3, the disparity between two images must keep stable, both the 3D image or image viewing, if the image is too long about two parallax eyes to watch or not, the average is not consistent, so that the viewer will appear dizziness and nausea. In addition, different body quality is not the same, even if set correctly, some people will also feel uncomfortable when watching 3D images, so 3D film is not suitable for everyone to watch.
Early in the last century, the development of 3D technology has made some achievements, but because of play equipment, transmission and storage devices are not developed enough, not widely used until recent years 3D image making and playing it has made great progress, especially the performance of a display device has become more and more powerful, image can support more and more high refresh rate, provides a strong support for 3D image playback. At present, the 3D image playback technology is very large, we particularly aim at a number of important transmission technology introduced, I hope readers can understand the current 3D image transmission and play principle. Generally speaking, the transmission of 3D images can be divided into two parts, "signal access and processing" and "signal broadcasting"
Nowadays, 3D technology is popular, and the trend of 3D has swept the whole video market, and a great 3D revolution is going on. And the domestic 3D products are also more and more, how to realize the 3D image playback has become the most concern of many video enthusiasts, the high quality 3D movie theater how to copy home? How do you choose the right 3D player? We can begin with 3D display technology, gradually understand the secret of 3D play, ready to select high-quality 3D broadcast equipment. Why can we see stereoscopic pictures? The formation of stereo images, we cannot do without the visual system of the human eye, the eye to see the image is three-dimensional, the reason is because people have two eyes, and two eyes with poor vision, object can be observed through different angles, while two eyes of observed images are transmitted to the brain when the brain will form a three-dimensional image, so we can feel the object is three-dimensional, and can distinguish between human and object distance and azimuth.To record and replay the 3D picture, there have been several mature technology support, we can through the terrestrial digital high-definition signal transmission and receiving 3D signals (now appear in Japan and South Korea), second online direct access to 3D experience sources (such as Dolby and nVidia provide a 3D movie download) third, through the Blu ray playback 3D Blu ray 3D film to watch, the fourth is through the installation of 3D on a personal computer display card collocation 3D display for stereo image playback, the last is a DIY 3D film, there have been many video camera manufacturers launched with double image shooting ability.
