IMAX will directly cooperate with the director to sharpen the picture, remove the particles and defects, and improve the resolution through the unique digital original reproduction technology (DMR), so as to improve the picture quality and create the best picture quality to play in the best projection system in the world.
these technologies are only part of the reason for IMAX to achieve higher brightness, color saturation and contrast. In addition, in the process of IMAX's digital original reproduction technology, we make full use of the extensibility of the dynamic range of the sound system to remix the sound channels.
