The difference between IMAX and 3D, what does IMAX3D mean?

IMAX is a big-screen movie, and 3D is a type of movie.

IMAX (abbreviation for ImageMaximum) is a movie projection system that can project larger and higher resolution movies than traditional film. The complete system includes film copies shot in IMAX specifications, projectors, sound systems, screens, etc. The standard IMAX screen is 22 meters wide and 16 meters high, but it can be played on larger screens, and larger IMAX screens have continued to appear so far.

Stereoscopic film is a kind of film. On May 24, 1953, stereoscopic film appeared for the first time, and Hollywood launched a kind of film. Viewers wearing special glasses found themselves hiding behind the escape train and the devil, as they did in thrillers such as The Devil in Bwana and House of Wax. This brought us into the era of three-dimensional movies.

In order to enhance the visual shock of the movie. Before IMAX, there were two large-screen projection systems: Cinemascope and VistaVision. These two systems affected the observability due to various reasons, such as complex installation, difficult operation, and unstable picture quality

. Therefore, it has not been promoted. The three Canadian inventors of IMAX (Graeme

Ferguson, Roman Kroitor and Robert

Kerr) had also previously studied a multi-projector large screen projection system similar to Cinemascope. , but their experiments at the 1967 Montreal World's Fair were not ideal and encountered many technical problems, which prompted them to turn to the development of a new single-projector, single-camera large-screen projection system. This ultimately led to the advent of IMAX.

The structure of IMAX is also very different from ordinary movie theaters. Due to the improvement in picture resolution, the audience can be closer to the screen. Generally, all seats are within the height of one screen (traditional theater seats can span 8 to 12 screens). In addition, the seat inclination is also larger (in the case of hemispherical screens) The screening room can be tilted up to 23 degrees) so that the audience faces the center of the screen.

IMAX is far from simple as it appears on the surface. Whether it is through cooperation between the director and the IMAX team and IMAX technology to make his vision a reality, or to improve the film's effects on a large scale, IMAX is involved in every stage of the film's production to show The ultimate movie viewing effect. No other company can do this.

IMAX is the only company that participates in the pre-production of films by Hollywood and domestic directors. Directors will also design and create customized scenes for IMAX.

Before an IMAX movie is released, the picture and sound channels of the movie will be re-recorded to provide unparalleled picture quality and sound effects, maximizing the viewing experience in an IMAX theater. IMAX will work directly with the director to use unique digital re-mastering (DMR) technology to sharpen the image, remove image grains and defects, increase resolution, etc., thereby improving the image quality and creating the best possible image quality in the world. Play on the best projection systems.

These technologies are just part of the process of IMAX achieving higher brightness, color saturation and contrast. In addition, during the processing of IMAX's digital original reproduction technology, the extensibility of the dynamic range of the sound system is fully utilized to remix the sound channels.

IMAX's digital cinema system uses a comprehensive set of IMAX patented technologies to continuously allow audiences to continue to enjoy an immersive feeling when watching movies. This experience called IMAX Experience? (IMAX viewing experience?) comes from the following technical factors:

IMAX's revolutionary projection technology projects crystal-clear images;

IMAX's powerful sound system provides laser-calibrated digital sound; the geometric design of the IMAX theater maximizes the viewing field of view; IMAX uses a unique dual projection system to ensure accurate picture calibration and screen brightness through an image optimizer - And this is just one of many unique IMAX patents.

This projection system can reduce defects by 50%, increase brightness by 60%, and increase contrast by 30% compared to traditional systems. In addition, unlike traditional projection systems, the brightness of the image remains consistent throughout the life of the xenon lamp. Compared with other 3D systems, IMAX's image optimizer also increases the brightness of 3D by more than twice.

Each movie's soundtrack is carefully recorded to fit IMAX's powerful laser-calibrated digital sound system, which has a sound dynamic range ten times that of ordinary theater sound. IMAX's digitally balanced point source technology plus five discrete audio channels allow listeners to locate the specific location of each sound coming from (traditional 5.1 audio channels often use many amplifiers, making it almost impossible to find the source of the sound). Every IMAX theater attempts to present the most accurate and realistic sound effects through maximum sound dynamics. All this makes the sound crisp and precise: even if a pin falls to the ground, you can clearly tell where it landed.

The design of each IMAX theater will bring you the most immersive movie-watching experience and enhance your personal feelings during the movie appreciation process. No matter the size of the screen, IMAX's theater geometric design ensures you have the best IMAX? viewing experience. IMAX's unique high-gain screen makes the picture very bright and the 3D effect is unparalleled. The screen is "top of the sky" from the wall to the wall and from the floor to the ceiling, is slightly arc-shaped, and is closer to the audience, thus maximizing the audience's viewing field of view.

These technologies are combined to create a high-end viewing experience that is vastly different from traditional 2D or 3D cinemas.

The digital technology used by IMAX eliminates the need for film copies. This not only increases the flexibility of movie screenings for theaters, but also increases the flexibility of movie screenings while maintaining a consistent IMAX viewing experience. Fundamentally, it also means that consumers can see more of their favorite IMAX movies - including of course Hollywood super blockbusters.

Recently, IMAX announced that it will launch a new generation of digital technology by the end of 2013. Compared with existing digital technology, the new IMAX digital laser projection equipment will present better brightness and clarity, a wider color gamut and deeper blacks, while consuming less power and lasting longer. The emergence of this technology will also enable the projection screen width to exceed 30 meters.

IMAX’s goal is to give people a reason to leave their home entertainment devices and make going to the theater an event not to be missed. We are always on the road of exploration, hoping to continuously improve the audience's IMAX viewing experience through new ways, whether it is technological advancement, the advancement of film release times, or including equipping top directors with the most cutting-edge IMAX cameras so that they can Express the story you want to tell in a way beyond your imagination.
