本国际标准旨在方便用户选择图像扫描仪。这个国际标准 规定制造商应在其扫描仪规格表中包含的最低信息。 本国际标准是为普通终端用户制定的。因此，它并没有描述所有的规格 具有特殊功能的扫描仪，如双面扫描或高速扫描。通过确保 扫描仪产品信息规范，该国际标准使最终用户能够做出有意义的 机器功能和性能特征的比较。函数中最有意义的参数 对性能进行了规定和定义，并提供了性能度量。 本国际标准进一步适用于使用最普遍的扫描仪类型，包括 扫描引擎（光机械物理设备）和基本图像处理的参数 处理过程包括以编码灰度输出的数字数据，或未编码的单位加半色调数据）。事实并非如此 需要高级应用程序处理规范，如OCR、翻译、矢量转换等，因为 扫描仪使用软件和/或硬件来实现一些扫描仪功能和控制，该标准包括 一些条目与软件有关，尽管该标准主要针对扫描仪硬件。制造商，在 他的选项可能包括对可能提供的此类附加功能的描述。这个标准也适用 不考虑图像质量，也不提供或使用相关的测试目标。

This International Standard is intended to facilitate user selection of an image scanner. This International Standard specifies the minimum information that shall be included by manufacturers in their specification sheets for scanners. This International Standard is made for the average end user. For this reason it does not describe all specifications of scanners with special features such as double sided scanning or high speed. By insuring consistency of specification of scanner product information, this International Standard enables the end user to make meaningful comparisons of machine functionality and performance characteristics. The most meaningful parameters of function and performance are specified and defined, and measures of performance are provided. This International Standard further applies to types of scanners which are most prevalent in use, including parameters for a scanning engine (an optomechanical physical device) and basic image processing only (those processes include digital data output with encoded gray scale, or unencoded single bit plus halftone data). It does not require specification of advanced application processing such as OCR, translation, vector conversion, etc. Because scanners use both software and/or hardware to achieve some scanner functions and controls, the standard contains some entries related to software even though the standard is primarily for scanner hardware. The manufacturer, at his option, may include description of such additional functionality which may be provided. This standard also does not consider image quality, nor does it provide or use related test targets.
