Ad tips off contract price in Australia at AUD 840

HTC is just weeks away from officially unveiling its next generation “One” smartphone, but that isn’t stopping a wealth of information on the device from making its way to the internet.
The last leak about the new HTC One came this week when some images of the device turned up on Chinese social network Weibo. The image shows the new One from all sides and showed the size of the smartphone compared to the HTC One Max phablet.
Today another leak has surfaced -- via an ad from Telestra, an Australian wireless carrier -- offering details on the dual cameras of the new HTC One. According to the ad, the dual cameras will of course allow for 3D photography.
However, the coolest thing about the dual cameras for most people will be the fact that they allow you to take photos and change the focus point after shooting the image. The dual cams will also allow users to create bokeh effects.
Other details of the phone tipped by the leaked ad include a 5-inch full HD resolution screen and BoomSound speakers up the front. The smartphone is tipped to sell for AUD 840 with no contract. That would equate to about $760 in the U.S., but with the notoriously high markups on technology products in Australia, the off-contract price in the U.S. is likely to be cheaper.

You can't sharpen a blurred(bokeh) image

The only way to do this is to take a regular picture with no bokeh effects and add bokeh in post processing.

I'm guessing with 2 cameras, they can take one with bokeh and another without. If you decide to change the focus, then they just take the part you want sharpened from the image without bokeh.

You can't sharpen a blurred(bokeh) image

Actually you can. It's called deconvolution, and was one of the original applications for which Fourier transforms were developed. Of course it's only been in the last 10-15 years that computers have gotten fast enough that you can do this in a practical sense. All you need is the point spread function (what does the lens blur a point of light into?) and you can reverse it.

In theory you don't even need a lens. If you can capture the intensity of the uniform white light hitting your wall through a window (easy part) and the direction of each photon (hard part), you can deconvolve it into an image of what's visible through your window. That's more or less what light field cameras do (they use multi-layered sensors to extract the direction info). The deconvolution is actually the same as the convolution - one Fourier transform takes you from the window image to the uniform white you see on your wall. A second Fourier transform brings that white wall back to the window image.

I'm guessing with 2 cameras, they can take one with bokeh and another without. If you decide to change the focus, then they just take the part you want sharpened from the image without bokeh.

The tiny sensors used in modern phone and point & shoot cameras means they have a huge depth of field. Practically everything is in focus. If you take two simultaneous pictures side-by-side, you get a stereoscopic effect which lets you extract distance info - just like your eyes and brain can when you watch a 3D movie.

You then use this 3D info to selectively blur the parts that are not in the plane you want to be in focus. The further something is from the plane, the more you blur it. As this technology develops, it's going to replace the bulky f/2.8 and f/2.0 lenses used to blur the background in portrait photography.

The technology looks good but there's 2 problems

1. requires a lot of processing for a phone
2. results are good but not great. Even with their best examples, you can see it cannot replace a good shot simply because OOF shots will lose a lot of details that cannot be realigned back.

Maybe they've improved it for HTC but I wouldn't bet on it.

This technology will also not replace the bulky high aperture lenses. In fact, the lens are so big simply because they are in big camera bodies with distance from the sensor. For example, you can see how much smaller the Full Frame Sony A7/R F/1.8 55mm vs the same lens on the Nikon. The closer distance reduces lens size.

It makes no sense from an economic standpoint anyways because then you would need 2 lenses, 2 sensors on the body and twice the processing power hoping you can get enough detail to recover an image. Just take a good shot in the first place.

The HTC will most like employ something much simpler than what you're suggesting. But I could be wrong. However I highly doubt HTC would put 2 cameras and pay licensing fees to drive down their margin further.

Since when we're they designing phone cameras with the intent of replacing a serious camera?
