标准摘要
[中文适用范围]： 本文件定义了在中等压缩率下能够表示连续色调灰度图像或彩色数字图像且无视觉损失的语法和 accompanying decompression process。典型压缩比为2:1至6:1，但具体取决于图像性质。该文件指定解码过程以将压缩图像数据转换为重建图像数据，并定义包含解释压缩图像数据信息的码流语法，同时提供指导以将源图像数据转换为压缩图像数据的编码过程。 [外文原描述]： This document defines the syntax and an accompanying decompression process that is capable to represent continuous-tone grey-scale, or continuous-tone colour digital images without visual loss at moderate compression rates. Typical compression rates are between 2:1 and 6:1 but can also be higher depending on the nature of the image. In particular, the syntax and the decoding process specified in this document allow lightweight encoder and decoder implementations that limit the end-to-end latency to a fraction of the frame size. However, the definition of transmission channel buffer models necessary to ensure such latency is beyond the scope of this document. This document: — specifies decoding processes for converting compressed image data to reconstructed image data; — specifies a codestream syntax containing information for interpreting the compressed image data; — provides guidance on encoding processes for converting source image data to compressed image data.
