Developed by Canada ’ s IMAX Corporation, IMAX was originally a film projection system utilizing a giant screen that allowed the projection of larger, higher-resolution images than traditional film. To distinguish its 3D system from this earlier widescreen 2D format, the company calls it IMAX 3D.
另外像近年火紅的「IMAX」，原是由加拿大 IMAX 集團所研發的一種巨型銀幕電影系統，可放映比傳統底片更大且更高解析度的影片；但 IMAX 本身僅為 2D 的寬螢幕電影，並不必然具有 3D 效果，必須特別標示「IMAX 3D」才表示該影片提供立體影像。
