IMAX (the abbreviation of Image Maximum, meaning "the largest image", the Chinese pronunciation can be read as "爱MAX") is a movie projection system that can project larger and higher resolution 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.

IMAX technology was first developed in Canada. Now the Canadian IMAX Company exclusively owns this technology, and IMAX theaters around the world provide technology and equipment. The development and promotion of IMAX has always been inseparable from large-scale exhibitions, science and technology museums and other public welfare activities and venues. And so far, IMAX theaters all over the world are almost evenly divided into two categories: science and technology museums and museum-based public welfare science popularization venues. and general theaters for commercial screenings.

The first IMAX movie in history was played at the Fuji Pavilion in Japan in 1970, and the first official IMAX projection equipment was installed at the Ontario Amphitheater in Toronto in 1971. Place's Cinesphere]. At the 1974 World's Fair in Washington State, the United States Pavilion displayed a giant IMAX screen of 27.3 x 19.7 meters. When the audience looked straight ahead, the picture was enough to fill the entire field of view. Among them, ***5 million people watched it. The vast majority of viewers thought it presented a strong sense of movement, and a small number of viewers even experienced a phenomenon similar to seasickness. In 1973, the first IMAX spherical screen appeared at the Ruben H. Fleet Technology Center Space Theater in Balboa Park, San Diego, California, USA. In 1986, at the Canada Pavilion in Vancouver, IMAX used The IMAX Experience technology to demonstrate IMAX's 3D movie effects for the first time.

Although IMAX has excellent image quality and has been around for a long time, due to the high cost of producing and showing IMAX and the difficulty of transportation, the playing time of IMAX movies is relatively short (usually 40 minutes). IMAX has never been popularized, and most of them are documentaries suitable for broadcast by science and technology museums, planetariums and other popular science institutions.

In the late 1990s, there was a trend of IMAX entertainment, and several entertainment-themed movies appeared, such as "T-Rex: Back to the Cretaceous" in 1998. the Cretaceous), 2001's "Haunted Castle" (Haunted Castle) and other IMAX3D movies. In 1999, Disney produced the IMAX version of "Fantasia 2000" - the first normal-length IMAX animation came out.

In 2002, IMAX and Universal jointly launched the IMAX version of "Apollo 13", which was the first work to use IMAX's DMR (Digital Re-mastering) re-production technology to convert traditional movies into the IMAX format. With this technology, many Hollywood visual effects blockbusters have been converted into IMAX format for release. Due to technical reasons, the length of the early films processed by DMR could not exceed 2 hours. However, in 2003, "The Matrix 2" was released. "Loaded into Battle" finally broke through this limitation and became an important milestone in the history of IMAX technology. At the end of 2003, "The Matrix: Revolution" became the first film to be released simultaneously in IMAX and traditional theaters.

Audiences very much welcome these IMAX versions of Hollywood blockbusters converted using DMR technology. The audio-visual effects are far better than traditional 35mm movies. One audience member who watched the IMAX version of "Apollo 13" commented: "The screen is huge and explosive. The sound effects and James Horner’s soul-stirring original music can only be felt in IMAX.” Therefore, in recent years, major Hollywood production companies have been optimistic about IMAX and have converted their blockbuster works into IMAX and even IMAX3D formats. "When you have a movie like Spider-Man II, it's just amazing if you don't convert it to this unparalleled IMAX format for audiences to enjoy," said Black, vice chairman of Sony Pictures. A waste of money." Therefore, films such as "Star Wars Episode II: Attack of the Clones", "Spider-Man II", "Harry Potter and the Prisoner of Azkaban", "The Polar Express: IMAX 3D Experience", " Popular blockbusters such as "Robot Adventures", "Batman Begins" and "Charlie and the Chocolate Factory" have been converted into IMAX format for screening. The famous director James Cameron is a staunch supporter of IMAX, in addition to prophecies. In addition to the fact that IMAX theaters will gradually end traditional theaters in the next "five or six years", he also personally directed an IMAX3D movie about the Titanic, "Titanic3D: Ghosts of the Abyss."

IMAX (15/70)

The spherical lens group has 15 holes per frame of film and is projected horizontally, from right to left (from the viewer's perspective) at 24 frames per second. Lens size: 2.772" inches (70.41mm) by 2.072" inches (52.63mm) Throw size: at least 0.80" inches vertically from the lens and 0.016" inches horizontally IMAX Dome / OMNIMAX Same as IMAX, except:

Special Fish The optical center of the spectacle lens set is 0.37" inches above the horizontal reference line and is projected onto the dome screen in an elliptical shape. The optimal viewing angle is between 20 degrees below the plane and 110 degrees above the plane.

[ Edit this paragraph] About IMAX 3D

IMAX3D is the projection technology of IMAX stereoscopic films. IMAX3D uses two reels of IMAX-specific 15/70 film. One reel corresponds to one eye, and it uses polarization filter glasses or infrared. The synchronized system works with electronic glasses to provide two separate images. Combined with the IMAX giant screen, IMAX3D can produce a realistic full-field three-dimensional effect.

IMAX 3D: Let you see more, hear more, and feel more. More

The IMAX Experience(R), presented in 3D, brings you the most immersive viewing experience in the world, mesmerizing millions of people around the world. The clear, lifelike and gorgeous three-dimensional images, combined with the top-notch surround sound system, make the audience feel like they are in the movie.

The all-round high quality of the IMAX 3D stereo experience makes its image effects stand out among the others in the world - creating a world-class experience. An important factor behind the wonders of IMAX 3D, the most realistic and immersive 3D ever created, is the use of dual film technology, which is far more advanced than traditional "red and blue" simulated 3D technology. Just putting the left and right eye images on one film will greatly reduce the clarity and color. However, IMAX 3D technology has no such regrets. It not only uses the world's largest film format (15/70), but also uses 2 separate rolls. Film captures and projects images simultaneously.

IMAX 3D Camera

The IMAX 3D camera is one of the highest-resolution image capture devices in the world, capable of simultaneously capturing two 65 mm images. The IMAX 3D camera can record the images of the left eye and the right eye on a wide film.

IMAX 3D projector

The IMAX 3D projector will. The two 15/70 format films for the left and right eyes are projected onto the special IMAX 3D screen at the same time. The audience must wear IMAX 3D glasses, which project the images of the left and right eyes onto the left and right eyes respectively. IMAX theaters use P3D glasses. Polarized lenses separate the images for the left and right eyes. The 15/70 film format used by IMAX is 10 times larger than traditional 35mm film.

The 15/70 film format and its unique IMAX projection technology are the two magic weapons for IMAX theaters to obtain super image clarity and color vividness
