The Iso-Deformation of Images and the Criterion for Delimitation of the Usable Areas in Cine-Auditoriums
Rubens Meister · Journal of the SMPTE · 1966
The origin of image deformations on screens, real and apparent deformations, and physical and psychic factors are discussed. Apparent deformations due to immobile and mobile images are considered with their respective deformation indexes. Isodeformation curves of mobile and immobile images and their design are described. Even and cylindrical screens are examined and the delimitation of apparent deformations is investigated. The uses of normal screens, wide screens, CinemaScope, Todd-AO-70mm and Cinerama are outlined.
