Summary

This ITU-T Recommendation | ISO/IEC International Standard defines a set of lossless (bit-preserving) and nearly lossless (where the error for each reconstructed sample is bounded by a pre-defined value) compression methods for coding continuous-tone, gray-scale, or colour digital still images.

This ITU-T Recommendation | ISO/IEC International Standard:

specifies a process for converting source image data to compressed image data;

specifies processes for converting compressed image data to reconstructed image data;

specifies coded representations for compressed image data;

provides guidance on how to implement these processes in practice.
