IMAX Digital
A digital version of IMAX started rolling out in 2008. The new system is a projection standard only; there are no digital IMAX cameras.
Digital IMAX systems can show either normal or 3D content in DCI or IMAX digital format (which in itself is a superset of DCI). Being a digital system alleviates the need for the use of bulky film reels and facilitate inexpensive distribution of IMAX features, the more compact nature of digital equipment means the system can fit inside a normal multiplex cinema complex rather than the specialised buildings IMAX normally requires.
Despite those advantages, one big disadvantage is the resolution of the picture is much lower than normal IMAX. The screens used by digital IMAX installations are also much smaller (28x58 feet) than those found in traditional IMAX cinemas. Despite these facts, the digital installations are marketed simply as IMAX, drawing no distinction to the traditional 15/70 IMAX – much to the dismay of 15/70 IMAX cinema owners.[5]
Deals have already been signed with Hollywood studios for IMAX 3D features, such as "Shrek Goes Fourth 3D".[6]
IMAX digital currently uses two 2K-resolution Christie projectors with Texas Instruments Digital Light Processing technology alongside parts of IMAX's proprietary system. The two 2K images are projected over each other, producing an image that is potentially of a slightly higher resolution than common 2K digital cinema. Originally, IMAX had been considering using two Sony 4K projectors.[7]
IMAX recently signed a deal with AMC to start utilizing this new technology beginning July 2008[8] in the US. In December 2008 two digital screens were opened inside Odeon Cinemas in the UK[9] and three inside Hoyts Cinemas in Australia with a fourth to follow later in 2009[10].
就是说如果维基所述属实，所谓的数字版IMAX只有这种大兴屏幕加两台2K放映机叠加的模式，根本就不是我们习惯的巨幕电影
