信息技术.办公设备.硬拷贝用图像质量属性的测量.单色文本和图形图像

[中文适用范围]： 本文件规定了设备无关的图像质量属性、测量方法和分析程序，用于描述硬拷贝设备输出图像的质量。本文件适用于打印机和复印机生成的人类可读单色文档。 这些属性、方法和程序依赖于印刷文本和图形图像的可测量特性。不需要特殊目标或参考图像，但只有当图像元素满足一些最低要求（例如大小或数量）时，它们才有助于进行充分的测量。本文件不适用于硬拷贝以外的媒体上的图像（例如视觉显示器上的图像）或仅用于机器可读的图像（例如条形码）。 [外文原描述]： ISO/IEC 24790:2017 specifies device-independent image quality attributes, measurement methods and analytical procedures to describe the quality of output images from hardcopy devices. This document is applicable to human-readable monochrome documents produced from printers and copiers. The attributes, methods and procedures rely on measurable properties of printed text and graphic images. Special targets or reference images are not required, but image elements are useful for adequate measurements only if they meet some minimal requirements, e.g. on size or number present. This document is not applicable to images on media other than hardcopy (e.g. images on a visual display) or to images that are intended to be machine readable only (e.g. bar codes).
