Scope:

This Recommendation | International Standard is applicable to continuous-tone - grayscale or colour - digital still image data. It is applicable to a wide range of applications which require use of compressed images.

This Recommendation | International Standard:

  • defines extensions [including variable quantization, selective refinement, tiling, and a Still Picture Interchange File Format (SPIFF)] to processes for converting source image data to compressed image data
  • defines extensions to processes for converting compresssed image data to reconstructed image data
  • defines coded representations for compressed image data
  • gives guidance and examples on how to implement these extensions in practice
  • describes compliance tests for these extensions.

Project need:

To review the Standard within the required 5 year period.
