"We store the extra range as metadata in the header," Matteini said, referring to section of a JPEG file that ordinarly stores metadata such as captions and camera information. A JPEG viewer that can't decode Dolby's extra info just skips over it. Personally, I like all the HDR work that's going on, overall, though the surreal images people sometimes deliberately create with HDR aren't to my taste. And I prefer images that show a broad dynamic range in one view rather than some kind of an interface to explore light and dark tones. I was glad that the tone-mapping settings Dolby used in the very limited examples on display showed a relatively normal view of the scene, not one of those over-the-top images with halos and crispy grunge textures.
Qualcomm showed off JPEG-HDR on an Android tablet prototype at the show, Its demo showed my bugaboo, the cathedral photo, Tapping on the stained-glass windows exposed them properly while everythinge else went nearly black, and tapping on a dim part of the interior showed it off while the windows washed out to complete whiteness, Part of the challenge in taking an HDR photograph is capturing images in rapid sequence to minimize problems of subjects such as people or leaves moving from one frame to the next, "We have a great framework for image capture which enables that sort of capture," said Phillippe Decotigne, a Qualcomm product manager, Qualcomm's processors can handle 13 images cemetery nights iphone case per second..
Dolby isn't the first to tackle HDR imaging challenges. Perhaps the most prominent alternative is JPEG XR, an "extended range" file format originally developed by Microsoft but now an industry standard. It can accommodate much a broader dynamic range than JPEG. But JPEG XR uses a different compression algorithm altogether (one that's better, Microsoft argues), which means you can't simply see a JPEG XR file unless you have software that knows how to decode it. Dolby licenses it technology to others, and JPEG-HDR is another example of that business in action. However, the terms aren't set yet, Matteini said.
"Maybe the decoder is free," so that it's easy for others to view the files, but Dolby would cemetery nights iphone case license the encoding technology so that makers of cameras or image-editing software would have to pay, High dynamic range photography is a popular way to bypass cameras' weaknesses in capturing bright and dark scenes, and Dolby hopes its technology will help, BARCELONA, Spain--High dynamic range (HDR) photography has largely been the province of photo enthusiasts willing to put up with its hassles, but Dolby Laboratories hopes to bring it to the masses with a semi-proprietary technology called JPEG-HDR..
When Apple announced the iPhone 4S in October, the company also said that it would offer an 8GB iPhone 4 for $99 with a two-year agreement. The iPhone 4, which previously came in 16GB and 32GB flavors, was on sale for $199 prior to that announcement. With new pressure from cheap alternatives, it only makes sense for Apple to offer a more affordable iPad to those who want it. If the company follows its iPhone model, it'll offer the iPad 3 at full price and some sort of iPad 2 at a discounted rate. The question, then, is will it be the 8GB model Digitimes claims will launch or something else?.
