ISO/IEC 10918-4:1999/AMD1:2013
Amendment 1 - Information technology -- Digital compression and coding of continuous-tone still images: Registration of JPEG profiles, SPIFF profiles, SPIFF tags, SPIFF colour spaces, APPn markers, SPIFF compression types and Registration Authorities (REGAUT)
发布时间：2013-05-07 实施时间：


ISO/IEC 10918-4:1999/AMD1:2013标准是一项数字压缩和编码连续色调静态图像的标准。该标准规定了JPEG配置文件、SPIFF配置文件、SPIFF标签、SPIFF颜色空间、APPn标记、SPIFF压缩类型和注册机构的注册要求。

JPEG配置文件是一种用于描述JPEG图像格式的文件。SPIFF配置文件是一种用于描述SPIFF图像格式的文件。SPIFF标签是一种用于描述SPIFF图像格式的标签。SPIFF颜色空间是一种用于描述SPIFF图像格式的颜色空间。APPn标记是一种用于描述JPEG图像格式的标记。SPIFF压缩类型是一种用于描述SPIFF图像格式的压缩类型。注册机构是一种用于管理JPEG配置文件、SPIFF配置文件、SPIFF标签、SPIFF颜色空间、APPn标记和SPIFF压缩类型的注册机构。

ISO/IEC 10918-4:1999/AMD1:2013标准的主要目的是为了确保JPEG配置文件、SPIFF配置文件、SPIFF标签、SPIFF颜色空间、APPn标记、SPIFF压缩类型和注册机构的统一性和互操作性。该标准的实施可以提高数字图像的压缩和编码效率，降低存储和传输成本，提高数字图像的质量和可靠性。
