Re: OT:JPEG patent
Prior art, which makes it easy to do away with. I wouldn't worry about it. Any big company with an interest in JPEGs will bury them.

Perhaps JPEG2000? (http://www.jpeg.org/JPEG2000.htm) Supposed to compress better while preserving more data (well, probably one or the other, but still..). Worst comes to worse, there's always MPEG I-frames. Some camera chips already perform MPEG compression for short movies, so it probably wouldn't be too difficult to modify them to just encode a single frame as an I-frame. Mpeg requires a royalty already, but since it's already been paid for... Also, hasn't JPEG been out for something like 15+ years? Isn't a patent only 17 years? Doesn't that mean they've gotten a patent awarded for something that is either prior art or about to expire in a few years anyway? later, patbob ([EMAIL PROTECTED]) - This message is from the Pentax-Discuss Mail List.

Re: OT:JPEG patent
I think, it's more like creating codec software. And as far as png goes, I can already see it: (Customer) Does this SuperDuper2000 camera outputs JPEG? (SalesP) No, but it uses the fantastic Portable Network Graphic format instead that allows... door slams Heck, I work in a software company, and I bet not more than half a dozen people here have even heard this acronim. Sigh... Mishka. From: Evan Hanson Subject: OT:JPEG patent Date: Thu, 18 Jul 2002 12:21:13 -0700 collecting licensing fees from those who create jpegs. I wonder if this will change any digital camera makers mind about offering a jpeg compression option or has it been out there too long. Maybe it's time we all switch to png. Evan Yahoo!

Re: OT:JPEG patent
Lol. Sometimes I forget how insulated computer cultures can be. My nine year old uses Linux, KDE, Gimp et. al, my wife who is pretty computer savy can't even stand to see the Linux login screen.
