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
