IMAX was invented by three Canadians: Graeme Ferguson, Roman Kroitor and Robert Kerr. 1967 World Expo held in Montreal, there were many technical problems in their multi-projector large-screen projection system, which prompted them to design a new system with single projector and single camera.

The image size of the traditional 70mm film is 48.5mm× 22. 1mm (Todd-AO), and the image size of the IMAX film is 69.6 mm× 48.5 mm.
