Canon EOS 70D Dual Pixel CMOS AF “revolutionary” system detailed

Canon’s “game changing” autofocus system on the new EOS 70D has been detailed, Dual Pixel CMOS AF, promising the smoothness of a dedicated camcorder with the image quality and lens flexibility of a DSLR. Billed as “revolutionary” by the company, the Dual Pixel system marks Canon’s concession to the increasing number of photographers wanting to frame using the LCD rather than the traditional viewfinder, with a new CMOS that can simultaneously capture images and perform phase-detection AF.

Canon’s system takes the same core approach as existing phase-detection auto focus. In both, the light entering the camera is split, and the difference in the focus point position between the two images is measured and analyzed to calculate the adjustments needed for focus.

Traditionally, a separate phase-detection AF sensor is used to perform those measurements; in Canon’s new system, however, the image sensor itself does the measurements, at the same time as capturing image data. That’s because Canon uses two photodiodes for each pixel: used side-by-side during focusing they work as the phase-difference sensor, while during image capture they’re combined to act as a single pixel in the final frame.

Overall, that means continuous autofocus throughout video recording, with support for tap-to-focus on the EOS 70D’s 3-inch touchscreen. Canon also offers face- and object-tracking, and argues that – while purists might choke at the thought of framing with anything other than the viewfinder – by switching to the Live View LCD even low-light situations are clearly visible.

Canon Dual Pixel CMOS AF overview:

The result is a camera that’s significantly swifter to autofocus than its predecessors, with Canon claiming the EOS 70D can lock 30-percent faster than the Hybrid CMOS AF II system in the EOS Rebel SL1. In fact, for most purposes it’s “nearly instantaneous” Canon says.

The first camera to support the Dual Pixel CMOS AF will be the EOS 70D, which is expected to ship from September. However, we’re fully expecting Canon to roll the system out to other models in due course.

How the Army of the Future Will Share Battlefield Intelligence

How the Army of the Future Will Share Battlefield Intelligence

Military technology doesn’t simply spring forth fully formed from a DARPA engineer’s head like some GI Athena. It requires extensive development cycles and field testing before it’s put on the front lines. At this year’s semi-annual Network Integration Evaluations (NIE) at the White Sands Missile Range, in New Mexico, Army researchers put a trio of technologies through their paces. Technologies that could radically alter how future wars are waged by delivering a more complete battlefield view to troops in the line of fire.

Google Reader has expired, but your data lives until July 15

The sun has finally set on Google Reader. Now please come by and get your stuff.

By now you probably already know that Google Reader has crossed over into the digital netherworld, joining many of its ill-fated Mountain View kin who were doomed never to exit beta.

When these sad departures occur, the ritual of going through the deceased’s basement begins, and in the case of Google Reader it turns out that the place was full of lots of digital detritus belonging to you and me, and hundreds of thousands (if not millions — we never really found out how popular Google Reader was in definite terms) of users.

PSA Download your Google Reader data by July 15th

Right on schedule, Google’s popular Reader site has gone offline. Visitors are now greeted with an apology message of sorts, along with a warning that data will be permanently deleted after 12PM PST on July 15th. In the meantime, you can use Google Takeout to download a copy of your subscription info, including lists you follow, starred items and notes. In fact, now might be an excellent time to snag data from other sites — you never know when Mountain View will opt to “sunset” your other beloved services, too.
