Abstract

The educational, business and military community has indicated a need for information dealing with the performance of projection equipment. Systems which present pictorial and alphanumeric video information to groups are well known. Many technologies are available, each with characteristic performance for brightness, resolution and color rendition. The end-user is primarily interested in the perceptual quality rather than what technology is used. The fixed and variable resolution standards address this need by providing a specification to describe parameters and performance characteristics that allow one to compare fixed or variable resolution systems in a meaningful way. Results should be available with a minimum number of measurements and expressed in common terms. These standards deal only with test methods and specifying terms for basic characteristics of front and rear projectors. This standard also could be applied to fixed resolution systems such as overhead projectors with LCD based data displays.
