标准摘要
[中文适用范围]： GB／丁20439的本部分规定了用于评价电子影像管理系统用平台式或滚筒式黑白反射扫描器性能 质量在其使用期间一致性的测试标板的特性。该测试标板用于： a) 对系统的性能进行常规检查； b) 确定系统的性能限度。 本部分适用于评价黑白或彩色办公文件(无论其有否半色调或彩色)用黑白扫描器的输出质量。 本部分不适用于彩色扫描器或扫描透明或半透明文件用的扫描器。 注：评价使用连续色调和彩色的黑白扫描器输出质量所用的附加标板，参见GB／T 20439．2。 [外文原描述]： This part of ISO 12653 specifies a test target for use in assessing the consistency of quality of performance over time of flat-bed and rotary black-and-white reflection scanners used in electronic image management systems. The test target is designed: a) to allow routine checks of the system's performance; b) to establish the performance limits of the system. This part of ISO 12653 is applicable to assessing the output quality of black-and-white scanners used for blackand- white or colour office documents, with or without half-tone or colour. It is not applicable to colour scanners or scanners used for the scanning of transparent or translucent documents. NOTE Additional targets for assessing the output quality of black-and-white scanners using continuous tone and colour are referred to in ISO 12653-2.
