1.1 本指南用于建立可视显示单元（VDU）（如阴极射线管（CRT））的操作特性。这些特性定义了计算机提供的数字信息（定义图像）与产生的光谱辐射出射度和CIE三刺激值之间的关系。该关系的数学描述可用于提供用于在VDU上精确显示彩色和彩色图像的附近设备独立模型。这里所指的CIE三刺激值是从CIE 1931 2°标准比色（明视）观测器计算的值。 1.2 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 VDU上显示的颜色是彩色图像再现的一个重要方面。VDU通常用作设计、编辑和批准媒介。图像通过某种捕获设备（如相机或扫描仪）输入计算机，由计算机操作员进行修改，然后发送到打印机或分色发生器，甚至发送到油漆分配器或纺织染色机。最终产品的颜色要与原始产品有明确的关系。用于建立输入、编辑和输出颜色（设备- 独立颜色空间）是CIE三刺激空间。本指南确定了推导模型的程序，该模型将VDU的数字计算机设置与原色发射的色光的CIE三刺激值相关联。

1.1 This guide is intended for use in establishing the operating characteristics of a visual display unit (VDU), such as a cathode ray tube (CRT). Those characteristics define the relationship between the digital information supplied by a computer, which defines an image, and the resulting spectral radiant exitance and CIE tristimulus values. The mathematical description of this relationship can be used to provide a nearby device-independent model for the accurate display of color and colored images on the VDU. The CIE tristimulus values referred to here are those calculated from the CIE 1931 2° standard colorimetric (photopic) observer. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The color displayed on a VDU is an important aspect of the reproduction of colored images. The VDU is often used as the design, edit, and approval medium. Images are placed into the computer by some sort of capture device, such as a camera or scanner, modified by the computer operator, and sent on to a printer or color separation generator, or even to a paint dispenser or textile dyer. The color of the final product is to have some well-defined relationship to the original. The most common medium for establishing the relationship between input, edit, and output color (device-independent color space) is the CIE tristimulus space. This guide identifies the procedures for deriving a model that relates the digital computer settings of a VDU to the CIE tristimulus values of the colored light emitted by the primaries.
