What is imax?
Today, the business cinema industry is developingrapid pace. The viewer, for example, is no longer surprised by the standard 2d display format, more and more often movie sessions are offered in 3d format with special glasses that provide a feeling of volume and realism during the viewing. However, most importantly, due to what the viewing of the movie turns into a mesmerizing spectacle - this is a series of technologies, based on the Aimax system. In this article we will describe in detail what is imax.
Aymax (Eng. imax) from English translates literally as "maximum image". IMAX is a wide-format cinema system, on the basis of which a number of film display technologies are based and a large network of cinemas around the world is built.
The format of the system was developed in the early 70'sof the same name by the Canadian corporation. The main advantage of Aimax technology is the use of perforated film with a width of 70 mm with longitudinal arrangement of film frames. A large area of the image thus has the greatest capacity of frame information, which allows to build screens in cinemas many times larger than other cinematographic systems.
Unlike other cinemas, in cinemasequipped with the IMAX technology, the screen width exceeds the length of the auditorium. Due to what the size of the displayed picture on the screen exceeds the viewer's field of vision, wherever he is sitting in the hall. Thanks to the Aimax system, when viewing a movie, the boundaries of the image become virtually invisible, which provides the viewer with the maximum immersive effect most felt when watching 3D movies.
There are several varieties of Aimax display technology, for example IMAX DOME, IMAX HD, IMAX 3D, etc. We'll talk more about the latter and find out, imax 3d: what is this format.
In fact, any image in 3d format is achieved by using a dual film camera. To display movies 3d in theaters IMAX apply two technologies:
- The simultaneous operation of two identicalprojectors. With this technology, a polarization method (based on transverse radiation waves) is used to obtain a stereo image. On the lenses of film projectors filters are installed, thanks to which the image for the left and right eyes is localized in mutually perpendicular planes.
- The second technology is designed to use the projection of the image with a doubled frequency - 48 frames per second.
