②3D is the abbreviation of tlllree—dimensional, which is a three-dimensional image. In essence, the principle of this technology is not complicated. People observe the subtle differences of objects through their left and right eyes, so as to perceive the existing state of objects in three-dimensional space. On the screen, as long as the picture seen by the left eye and the right eye is not an image, the whole picture will be stereoscopic.
③3D technology has developed rapidly in commercial applications. More and more 3D cinemas will be invested and built, and the number of 3D movies is also increasing greatly. With the rapid development of 3D technology, the mutual penetration of movies, music, animation and online games makes 3D technology show unprecedented strength in the field of electronic consumption, and the trend of using 3D technology in consumer electronic products has become very obvious.
④3D technology is not only accepted by film industry, but also favored in TV field. Now all TV manufacturers take the opportunity to push 3D TV, hoping to lead the development trend of flat-panel TV in the future. Television media are also scrambling to introduce this advanced visual technology into the broadcast of sports competitions. In the English Premier League, which started on the evening of1October 3rd 10 and 1 7, Arsenal played against Manchester United at home, which has become the first sports competition in British sports history broadcast by 3D technology.
In addition, 3D digital cameras and 3D digital photo frames were commercialized at the end of last year. You can access a 3D digital camera in the following ways
Double lenses overlay the same scene to produce a stereoscopic image, or use 3D function to compare different color modes. 3D digital photo frame uses polarization principle to refract different images to both eyes at the same time, and can even be used as 3D glasses to stereoscopic ordinary photos. In June+10 this year, Panasonic exhibited the world's first high-definition 3D camera, and its dual-lens design can be said to be very unique. Panasonic integrates the lens, camera front end and dual memory cards into a whole, thus making the user's body lighter and more flexible when taking photos with his hand. At the same time, the machine can automatically correct images and record 3D images directly without using any additional equipment.
However, it will take some time for the real 3D era to come. Although you can go to the cinema to experience 3D at present.
Movies, but resources are quite limited. 3D TV faces the same problem. Without 3D program content, 3D TV can only
This is a decoration. The formulation of technical standards is also a realistic problem that needs to be faced and solved. In addition, health and safety are also 3D.
A difficult problem to be solved urgently in display technology. The results show that the audience will move back and forth quickly because of their eyes when watching stereoscopic images.
Move, it is easy to cause eye fatigue. Therefore, for the visual enjoyment brought by realistic 3D images, we
Still need to wait patiently.
