What is IMAX?

What will come to mind when you hear IMAX? Images? Or the sound system? Recently, words such as "IMAX laser" and "IMAX laser / GT technology" have appeared. I don't know what is. Aren't there a lot of people like this?

Surrounded by such mysteries. With regard to IMAX, this time we will explain the simple history and its characteristics.

It started 50 years ago.

IMAX refers to the animated film specification and projection system developed by the Canadian "Multi-screen Company (later changed to IMAX)" 50 years ago.

This is what a frame can show with a film area of 70 points (usually 35 points) and a wide range of high-precision image records.

Use a dedicated IMAX film camera when shooting. However, due to the use of huge film, the camera becomes larger, the equipment is very expensive, and it is rarely used when shooting in intense scenes (there are also directors). The reality is to shoot several scenes of positive films with IMAX film cameras.

IMAX digital cameras that do not need film are also popular, but their images are not as good as film cameras, with a digital resolution of 2K / 4K, while film is above 8K. IMAX film still has an overwhelming sense of beauty.

However, no matter how many good-looking images you receive, there is no point without the equipment to show it.

The image of the IMAX film has been cut off up and down?

The aspect ratio of IMAX film is 1.4315, and its shape is close to square. Therefore, in the general cinema screen (2.35V1), the upper and lower parts of the image are cut off.

This is also true in the IMAX Digital Theatre, which has an aspect ratio of 1.90 to 1.90. Because it matches the screen size of the IMAX digital camera, the image of the film camera will eventually be cut off. So where is the cinema where you can enjoy IMAX film directly?

The original IMAX cannot be enjoyed in Japan.

In fact, for images shot with IMAX film, there is no "cinema that can show film directly" in Japan. The only facility that can enjoy IMAX images is the Kagoshima Municipal Science Museum (Cosmic Theater), not movies, but images of celestial bodies.

In Japan, although it has been said, there is a "IMAX Theater" in the world that can show IMAX movies. However, there are only 20 of them. After listening to this, what kind of IMAX00 are we enjoying now? It's going to be like this.

A little bit here.

There is no IMAX theater in Japan that can show film, but there are two very large cinemas with full screens in Japan, which can be viewed with the original aspect ratio of IMAX film. That's the 109th Cinemas Expo City in Osaka and the big Cinema Sunshine in Ikebukuro, Tokyo. This service will be introduced later in "IMAX Laser / GT Technology".

Now what we enjoy in Japanese cinemas are "using special projectors to show digital data generated from images captured by IMAX film", "direct projection of IMAX digital data images", It is divided into "films that convert general film and digital images other than IMAX to IMAX format and show them".

It's all IMAX! It's easy to get together, but there's actually a difference.
