Why don't cameras support JPEG 2000 format?

Question

The original JPEG format was updated in 2000 to provide a variety of features including less artifacts, better compression and lossless compression. Why haven't cameras updated to use this new format?

Answer

JPEG 2000 has not garnered wide acceptance due to a few factors.

• Lacking backwards compatibility to JPEG
• Lack of wide browser support
• Questionable legal status
• (Only) 20% higher performance, while considering how inexpensive storage is
• Additional processing power/time needed to create
• JPEG already considered quite good
• Amount of rework to the code in cameras and desktop software is high
