标准范围

该推荐国际标准定义了一组无损（比特保留）和有损压缩方法，用于编码双层、连续色调灰度、调色板颜色或连续色调颜色数字静止图像。本推荐国际标准:-指定用于将压缩图像数据转换为重构图像数据的解码过程；-指定包含用于解释压缩图像数据的信息的码流语法；-指定文件格式；-提供关于用于将源图像数据转换为压缩图像数据的编码过程的指导；-就如何在实践中实施这些流程提供指导。注-由于本规范仅在ISO/IEC JTC1于2000年批准第一版后才作为通用文本首次发布，因此ITU和ISO/IEC版本中的版本号偏移1。这是ITU-T T.800的第三版和ISO/IEC 15444-1的第四版。

This Recommendation International Standard defines a set of lossless (bit-preserving) and lossy compression methods for coding bi-level, continuous-tone grey-scale, palletized colour, or continuous-tone colour digital still images.
This Recommendation International Standard:
- specifies decoding processes for converting compressed image data to reconstructed image data;
- specifies a codestream syntax containing information for interpreting the compressed image data;
- specifies a file format;
- provides guidance on encoding processes for converting source image data to compressed image data;
- provides guidance on how to implement these processes in practice.
NOTE - As this specification was first published as common text only after ISO/IEC JTC1 had approved the first edition in 2000, edition numbers in the ITU and ISO/IEC versions are offset by one. This is the third edition of ITU-T T.800 and the fourth edition of ISO/IEC 15444-1.
