This Standard defines image system contrast ratio and its measurement.
This Standard defines image system contrast ratio and its measurement. It applies to permanently installed and temporary display systems and all displayed images regardless of AV technology (e.g., direct view display, rear projection, front projection). This Standard defines four contrast ratios based on content viewing requirements. The AV system includes the display, sources, signal distribution, and the environment. System contrast ratio measurements are taken in the system’s typical use case (e.g., classroom with ambient light and a video distribution system throughout the school). Practical metrics to measure and validate the required contrast ratios are provided.

AVIXA's consensus standards development process is accredited by ANSI, a private, non-profit organization that administers and coordinates the U.S. voluntary standardization and conformity assessment systems. ANSI is the sole U.S. representative of the two major non-treaty international standards organizations, the International Organization for Standardization (ISO), and, via the U.S. National Committee (USNC), the International Electrotechnical Commission (IEC). Accreditation by ANSI signifies that the procedures used by AVIXA in connection with the development of American National Standards meet the Institute's essential requirements for openness, balance, consensus, right to appeal, and due process.
