Abstract: The traditional way to measure screen uniformity in Cinema is by pointing manually a measuring device at a few locations on the screen. This method is subject to operational errors and not foolproof. As an increased quality control is required by Digital Cinema a better method is needed. It is also worth noting that luminance variations are also affecting color measurements. Large screen projection is always subject to vignetting. A set of practical vignetting models is proposed to help define a typical vignetting effect for cinema projection. From these models one can devise a method and apparatus that may give practical luminance uniformity measurements. A proposal for specifications with tolerances is given.
