IMAX is the full name of Image Maximum, which means the largest image. It is a film projection system, which can project a higher resolution than traditional negatives. The standard IMAX screen is 22 meters wide × 16. 1 meter high (72 feet× 53 feet), but it can be played on a larger screen.
In order to achieve this effect, the shooting and projection of IMAX movies need to use professional supporting equipment and a large enough cinema, and it is impossible for a small cinema to expand the IMAX movie screen.
2. China Giant Screen Cinema
Chinese giant screen is not only aimed at improving the brightness of the picture, but also includes the reprocessing of the digital film master, the optimization and correction of the picture, the design of the picture, the sound control and the design of the projection environment. Generally speaking, Chinese giant screens will use huge metal screens with a width of more than 20m × 12m.
As for sound effects, China Giant Screen is even better than IMAX, which uses 1 1. 1 stereo surround sound, while IMAX uses 7. 1 stereo surround sound. At the same time, the screen brightness of "China Giant Screen" is relatively high, and the projector used has good saturation and clarity.
Compared with IMAX, Chinese giant screen does not need special supporting equipment, which can be understood as a single projection equipment, rather than a one-stop facility like IMAX.
Technical advantages of China's giant screen
1, patented image optimization technology
CGS China giant screen dual-engine digital projection system adopts ProX? Image optimization technology can process the picture frame by frame in real time, optimize the projection picture according to the environment and characteristics of each CGS cinema, and optimize the precision of film signal processing through the optimizer to realize uncompressed JPEG2000 signal stream processing. The 3D brightness can reach 14fL+.
2. Sound reproduction system
Object-oriented sound reproduction system. CGS China Giant Screen System adopts immersive sound effects based on sound objects and point-to-point sound objects.
3. Design criteria
The technological design goal of CGS China Giant Screen Cinema is to provide the best screening effect: first, the picture is clear, the color is full, and the sound field uniformity of the theater is high; Second, provide a comfortable viewing atmosphere.
The exclusive cinema based on customization has these characteristics: professional cinema design, reducing stray light interference, high contrast and transparent image; The sound effect is shocking and the timbre is accurate; Super wide row spacing and special angle seat design; The lower viewpoint is lower and the slope is higher. Full-court fresh air system, independent environmental protection, green and healthy viewing (applicable to CGS China giant screen first-class system).
4. Master the production process professionally.
CGS China's giant screen master technology accurately converts the picture and sound of the film, realizing the full coverage of 4K, HDR (high dynamic range), HFR (high frame rate) and more high-tech formats, meeting the high-standard projection requirements of high-end giant screens. The master of the digital source has been processed for more than 4K, and at the same time, the image clarity, picture sharpness and color saturation of the projection effect have been improved.
