Display Monitor Measurement Methods under Discussion by EIA (Electronic Industries Association) Committee JT-20, Part 1: Monochrome CRT Monitor Performance, Version 2.0

摘要

The goal of this document is to provide practical, tested procedures for obtaining and reporting consistent and repeatable performance measurements of monochrome CRT displays, especially those used in gray scale imagery analysis. The reported results of these measurements can be used to determine whether a candidate display can meet the needs of Image Analysts and other critical users such as radiologists in the medical imaging community, thus enabling users to easily make an objective comparison when choosing between candidate displays. The goal is not to reinvent, but to identify, incorporate, and revise as appropriate, measurement standards that other standards generating bodies have established. The ultimate goal of establishing such measurement and reporting standards, and promoting their use, is to provide a common language by which display users can communicate their display needs to manufacturers, better enabling them to recognize the critical performance criteria which must be met in order to successfully provide increasingly higher quality, more cost effective monochrome CRT displays to the user. We believe this document presents a practical and sufficiently detailed set of measurement procedures for evaluating the performance of monochrome CRT monitors for imagery applications, and owes much to existing standards documents and to the people and organizations who created them. Existing standards documents provide established methods for evaluating monochrome CRT displays targeted for text or graphics applications. This document is intended to be complementary to existing standards by addressing the performance issues which effect whether the Image Analyst can reliably and efficiently perceive low contrast detail in monochrome images.
