IMAX is the only company involved in the pre-production of films directed by Hollywood and domestic directors, and the directors will also design and create customized scenes for IMAX.
Before an IMAX movie is released, the picture and audio track of the movie will be re-recorded, thus providing unparalleled picture quality and sound effects and maximizing the viewing experience of IMAX theaters. IMAX will directly cooperate with the director to sharpen the picture, remove particles and defects and improve the resolution through the unique digital original reproduction technology (DMR), so as to improve the picture quality, create the best picture quality as much as possible, and play it in the best projection system in the world. These technologies are only part of the reason why IMAX achieves higher brightness, color saturation and contrast. In addition, in the process of digital original sound reproduction technology of IMAX, we make full use of the expansibility of the dynamic range of the sound system to mix the sound channels.
IMAX's digital cinema system uses a comprehensive set of IMAX patented technology to continuously let the audience enjoy the immersion when watching movies. This is called IMAX experience? (IMAX viewing experience? ) Experience comes from the following technical factors:
IMAX revolutionary projection technology, presenting a crystal clear picture; IMAX's powerful sound system provides laser-calibrated digital sound; The geometric design of IMAX cinema broadens the viewing field to the greatest extent; IMAX uses a unique dual projection system to ensure the accurate calibration of the picture and the brightness of the picture on the screen through the image optimizer-this is just one of IMAX's many unique patents. Compared with the traditional system, the projection system can reduce 50% defects, improve 60% brightness and 30% contrast. In addition, unlike the traditional projection system, the screen brightness of the projection system can be consistent throughout the life of the xenon lamp. Compared with other 3D systems, IMAX's image optimizer has also increased the brightness of 3D by more than two times.
The sound track of each movie will be carefully recorded to adapt to IMAX's powerful laser-calibrated digital sound system, and its sound dynamic range is ten times that of ordinary cinema sound. IMAX's digital balance sound source technology plus five scattered audio channels can help listeners find the specific location where each sound comes from (the traditional 5. 1 audio channel often uses many speakers, so it is almost impossible to find the source of the sound). Every IMAX cinema tries to show the most accurate and authentic sound effects through the loudest sound. All these make the sound clear and accurate: even if a needle falls to the ground, you can clearly tell where it falls.
The design of every IMAX cinema will bring you the most immersive viewing experience and strengthen your personal feelings in the process of movie appreciation. No matter how big the screen size is, the geometric design of IMAX cinema can ensure that you have the best IMAX? Movie viewing experience. IMAX's unique high-gain screen makes the picture very bright and the 3D effect is unparalleled. From wall to wall, from floor to ceiling, the screen is "upright", slightly curved and closer to the audience, thus maximizing the audience's vision.
These technologies combine to create a high-end viewing experience that is completely different from traditional 2D or 3D cinemas.
The digital technology adopted by IMAX reduces the demand for movie copies, which not only improves the flexibility of showing movies in cinemas, but also fundamentally means that consumers can see more IMAX movies they like-including Hollywood blockbusters, of course.
Recently, IMAX announced that it will launch a new generation of digital technology at the end of 20 13. Compared with the existing digital technology, the new IMAX digital laser projection equipment will present better brightness and clarity, wider color gamut and deeper black, while consuming less power and having a longer life. The emergence of this technology will also make the projection screen more than 30 meters wide.
The goal of IMAX is to give people a reason to leave their entertainment facilities at home, and to make going to the cinema a must-see activity. And on the road of exploration, I hope to continuously improve the audience's IMAX viewing experience through new ways, whether it is technological progress, the advance of film release time, or equipping top directors with cutting-edge IMAX cameras, so that they can express their stories in an unimaginable way. Due to the difficulty and high cost of film production, there are strict regulations on the protection of IMAX.
The film storage environment must be stored in a space with constant temperature and humidity 24 hours a year. In Asia, there are quite a few requirements for eliminating excessive moisture and dust in the air.
On the other hand, the whole process of film transportation adopts an all-aluminum sealed box, and the inside of the box provides considerable shock absorption and support, so that the film is strictly protected during transportation.
IMAX projectionists need to wear pure cotton gloves all the time to avoid fingerprints, grease or sweat on their hands from touching the film, otherwise, under the magnification of 145000 times, a little flaw will be obvious. IMAX projection room is mainly composed of projection operation room and glasses cleaning room.
Besides an IMAX projection system, there is also a 35mm projector in the projection operation room, so in the future, IMAX cinemas can also be used for general 35mm commercial films.
Projection room temperature: 20-24 degrees (year-round temperature control).
Projection room humidity: 45-55 degrees constant humidity (annual humidity control).
In addition to constant temperature and humidity, dust control is also an absolute requirement in the environmental requirements of the projection room. In particular, an air filter is installed in the air circulation system of the projection room, so that the air filtration rate can reach over 95%.
The main equipment of the projection operation room includes a main console, a four-light-box (2.4 kW each) dual-lens projector (including four rectifiers), an audio cabinet (including seven power amplifiers, a playback server, a mixer, a synchronizer, a communicator and an uninterruptible power supply), two three-layer optical disc players (each with its own independent power supply), a film rewinding table and an uninterruptible power supply.
The mirror washing room is equipped with a set of automatic 3D glasses washing equipment.
The above workspace adopts excellent sound insulation and wall vibration materials, which are enough to absorb the noise generated by equipment operation. In addition, it is worth mentioning that the projection window glass adopts double-sided optical glass, and the middle is vacuumized, which completely blocks the transmission of the running noise of the projection unit to the cinema.
Due to the strict requirements of the projection room space on the air conditioning environment, another air conditioning system provided by the emergency standby system is set outside the main air conditioning system. To maintain the requirement of air conditioning operation 24 hours a year.
