HTC One (M8) Duo Camera explained: always-on “refocus”
The depth of field information collected by the secondary lens (at the top) is stored with every photo, and allows to “refocus” the picture after the shot has been taken, by adding artistic out-of-focus blur effect (known as bokeh).
In contrast, HTC's Duo Camera captures the depth information together with every photo, without causing any delays. You can apply the post-processing effect to all pictures you have taken, no matter if they were captured moments, or weeks ago. By knowing the depth of the scene, the One can automatically select which parts of the picture to blur, in order to emulate this DSLR-like bokeh out-of-focus artistic blur. Other options are to add color or augmented reality effects. Check out the slideshow below to see HTC's demos.
The method for collecting the additional depth (distance) information may also help for faster auto-focus – HTC says it is “faster than ever, capable of focusing in 0.3 of a second.“ This matches the result that Samsung touted for the S5 as “world's fastest.” In the case of the S5 however, these results are achieved thanks to a phase-detection auto-focus system (first in a phone).
The new HTC One doesn't feature optical image stabilization, since the technology is not possible with dual-lens camera systems. HTC claims that its digital Smart Stabilization works just as well, but we will have to test it before we pass any verdict.

The sensor is the same four megapixel backside, NO NO NO, the output photo Is just Too small .
Massive shame & mistake, it should have been 6 megapixel ultrapixel), apart from this I love the phone :(
No OIS is also a No No, prefer OIS to changing the focus after the photo is taken.

Extremely unsharp pics, even the HTC one wasn't this bad. I hope for HTC's sake these pics are 100% to show effect and 0% care of quality when taken.

They're all so out of focus (not just the ones that are supposed to be). The subjects are stretched on the sides and they're just crappy photos! And these are the factory photos!

1st thing HTC one 2013 pics are not that bad, its good. and if this is dual cam then the final output pic will be better so 4mp with dual camera is ok, OIS is not possible with dual camera.
i m ready for upgrade, bring it in INDIA

Most of these are gimmicks. Still the camera, why HTC?

That's pretty unusual thinking.
People were complaining, about our camera quality. Solution?
Lets put two cameras in next model. That will help...

Nokia Refocus!" Alternatively, you might be
shouting about Samsung's Selective Focus , that comes
with the Galaxy S5 , or Sony's Background Focus that's
in the Xperia Z2, or LG's Magic Focus in the G Pro 2," Nokia refocus sounds cooler

You nailed it, Nokia Refocus does even a better job without using dual cameras.
