ISO/IEC 23000-3:20 07规定了数字照片库应用的解决方案。它标准化了图像和相关元数据的打包，支持跨不同设备和平台的互操作交换。支持的元数据包括图像采集参数（如日期、时间和相机设置）以及MPEG-7视觉内容描述。这使得符合标准的设备能够支持新的内容增强功能，如智能浏览、基于内容的搜索或自动分类。ISO/IEC 23000-3:20 07使得根据照片的内容将照片组织成类别成为可能，例如，描绘的人物和地点，或者照片中发生的事件；通过照片集合执行基于内容的高级搜索；将照片和喜爱的显示方式捆绑到单个MPEG-4文件；链接到外部资源，如其他图像（MPEG-4文件之外）或网页。ISO/IEC 23000-3:20 07将一组JPEG压缩图像封装在MPEG-4文件中的区域方法的主要组成部分；描述单个图像和整个集合的MPEG-7元数据的简明子集；将该二进制MPEG-7元数据嵌入到MPEG-4文件.ISO/IEC 23000-3:20 07中的方法是对数字图像集合与元数据的持久和可互操作链接的需要的响应，以便支持对内容的高级访问。它为从消费数码摄影到广告和电子商务的各种应用提供了灵活的解决方案。

ISO/IEC 23000-3:2007 specifies a solution for digital photo library applications. It standardizes the packaging of images and associated metadata, enabling interoperable exchange across diverse devices and platforms. The supported metadata include image-acquisition parameters (such as date, time and camera settings), as well as MPEG-7 visual content descriptions. This allows conforming devices to support new content-enhanced functionality such as intelligent browsing, content-based search or automatic categorization.

ISO/IEC 23000-3:2007 makes it possible to

• organize photos into categories based on their content - for example, the people and places depicted, or events taking place in photos;


• perform advanced content-based searches through collections of photos;


• bundle photos and favourite ways to show them, into a single MPEG-4 file;


• link to external resources such as other images (outside the MPEG-4 file) or web-pages.

The major components of ISO/IEC 23000-3:2007 are

• a method to encapsulate a set of JPEG compressed images in an MPEG-4 file;


• concise subsets of MPEG-7 metadata to describe the individual images and the overall collection;


• a method to embed this binary MPEG-7 metadata in the MPEG-4 file.

ISO/IEC 23000-3:2007 is a response to the need for persistent and interoperable linking of digital image collections with metadata in order to support advanced access to content. It offers a flexible solution for applications ranging from consumer digital photography to advertising and e-commerce.
