Luminance, contrast ratio, and gray scale

Abstract

This chapter describes the most prominent display metrology parameters and procedures, including luminance, contrast ratio, and gray scale. Each topic will be explained with typical examples; an overview is also provided in chapter "{contains as normal subgroup}Overview of the Photometric Characterization of Visual Displays." The display measurement equipment required to carry out these measurements is presented in chapter "{contains as normal subgroup}Measurement Devices," with test patterns provided in chapter "{contains as normal subgroup}Standards and Test Patterns." All these measurements can be performed under varying conditions such as changing viewing angle (chapter "{contains as normal subgroup}Viewing Angle”) or ambient light levels (chapter "{contains as normal subgroup}Ambient Light”).
