信息技术 办公设备 规定图像扫描器的最少信息

[中文适用范围]： 本国际标准旨在方便用户选择图像扫描仪。 本国际标准规定了制造商应在其扫描仪规格表中包含的最少信息。 该国际标准是为普通最终用户制定的。 因此，它并未描述具有双面扫描或高速等特殊功能的扫描仪的所有规格。 通过确保扫描仪产品信息规范的一致性，该国际标准使最终用户能够对机器功能和性能特征进行有意义的比较。 指定和定义了最有意义的功能和性能参数，并提供了性能测量。 本国际标准还适用于最普遍使用的扫描仪类型，包括扫描引擎（光机械物理设备）的参数和仅基本图像处理（这些过程包括带有编码灰度的数字数据输出，或未编码的单比特加半色调数据）。 它不需要高级应用程序处理的规范，例如 OCR、翻译、矢量转换等。 由于扫描仪同时使用软件和/或硬件来实现某些扫描仪功能和控制，因此该标准包含一些与软件相关的条目，尽管该标准是主要用于扫描仪硬件。 制造商可以选择包括对可能提供的附加功能的描述。 该标准也没有考虑图像质量，也没有提供或使用相关的测试目标。 [外文原描述]： 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.
