JPEG XR, formerly known as Microsoft HD Photo, is now an international standard, as reported in a JPEG press release.

Thanks to Bill Crow's blog for calling this to my attention.

The Joint Photographic Experts Group (JPEG) has issued a press release on developments from the 47th WG1 meeting in San Francisco. Here are a few highlights:

• JPEG XR (formerly Microsoft HD Photo) has advanced toward becoming an international standard.
• There is lots of new stuff and more solid versions of existing stuff in JPEG2000, including specifications for security, access by mobile and wireless devices, inclusion of OCR results in image files, and 3-D data.
• Work is starting on a color version of JBIG2, even though the "B" in JBIG stands for "bitonal."

All of this taken together gives a certain feeling of feature bloat.

JPEG2000 has found a niche in digital cinema, strengthened by Digital Cinema Initiative's approval of the JPEG2000 based DCI specification 1.1 for distribution of digital movies to theatres. Transformers and Harry Potter and the Order of the Phoenix are among the movies that have already been released in JPEG2000.

Microsoft has submitted its HD Photo image format to the Joint Photographic Experts Group (JPEG) for adoption as a standard, with the proposed name of JPEG XR. The name has potential for confusion, as the format isn't a variant of what's popularly known as the JPEG image format. (But then, neither is JPEG2000.) The format was originally known as Windows Media Photo, so Microsoft has been moving at least the labeling of the format from an OS-specific one to a general standard. Microsoft is hoping the final standard, if approved by JPEG, will be out by mid to late 2008. The company says it "will offer a royalty-free grant for its patents that are required to implement the standard."
