HTC Gallery update allows for sharing of Duo Cam images


We were not too impressed with results from the HTC One M8's Duo Cam in our review,  but nevertheless, its secondary camera for capturing depth information and itscorresponding features make the HTC one of the more interesting smartphone cameras released so far in 2014.

One of Duo Cam's limitations has been that the editing features, such as UFocus for changing the focus point after capture or Foregrounder for applying effects to the back- or foreground of an image, could only be used on the device itself. This has changed with the latest update to the HTC Gallery App that allows you to share a Duo Cam image with others via the new Duo Effects Gallery web interface. In the interface the image can be manipulated in pretty much the same way as on the phone but the functions are a little restricted. For example, UFocus lacks the blur strength slider of the device version (see the example above).

The HTC One M8's Duo Cam allows you to refocus an image after it has been taken.
The new version of HTC Gallery lets you share an editable image via social networks or email.

Of course you still need a One M8 to capture the image but the Duo Effects gallery is a nice way to share your image results and give others an impression of how this new technology works. If you are the lucky owner of a HTC One M8 you can download the update now from the Google Play Store.

But it works extremely fake and circular, not depending of the distance between foreground and background. When you click on the stairs that are inside the bike, they get in focus, and everything else gets out of focus in a circular way, even the same stairs, left from the stairs inside the bike. And when you focus on the bike, only parts of the bike get in focus and the stairs inside the bike get out of focus, where the same stairs outside of the bike are in focus. I don't know about you guys, but this is very fake out of focus blur. And why does everybody want this feature on their smartphone? DSLR-like out of focus background, when it is impossible to get such bokeh out of such tiny sensor.

I don't even get the whole lytro thing. You shoot a flower, why would you possibly want to refocus after taking the picture on the background and blurring the flower?!

Well done HTC!


I think the software version of these type of images are almost getting as good as what the Lytro light field cameras are producing...doesn't bode well for light field cameras.


Think again :)
I don't necessarily like or need the lytro (however i do appreciate their idea and future possibilities it brings).
But this is just much too messed up. Even in very easy situations the results are terrible wrong, and even in the examples featuring the feature :).
maybe if in some future this idea will really work, we'll be able to simulate super bokeh, etc with just a phone... but there is a long way to go...


I think that is the big thing missing from the Lytro cameras...the backgrounds are just 'smoothly' out of focus. Not everyone likes bokeh or certain types of bokeh but for those of us who do, the light field blur just doesn't cut it. I guess we will see what the future brings.
A light field camera with a four thirds mount might be interesting...if it were possible. Best of both worlds with the use of legacy glass.


This should show that HTC cares about their customers' satisfaction.
When they introduced Zoe feature, they supplemented it with Zoe app and Video highlight.
Now this update to gallery is for the duocam feature.

Credit where it's due. Keep up the good work.

it looks like a beginner's quacky usage of photoshop. interesting potential though


Is the HTC actually allowing selective focus?

It seems like its just capturing depth info at the pixel level and applying fake digital blur based on that how far that pixel is from what is in focus. In this case, its not refocusing at all... its more like digital blurring based on depth information.

well, it knows what's in the background and what's in the foreground of an image and then applies selective blur. With the DoF of a smartphone it doesn't matter too much where it focuses, most of the scene would be in focus anyway.

It doesn't do a fantastic job of it either. Half of the bike is blurry because it thinks it's in the background. I guess it's a good work around for a small sensor, if the could make it work well.


I've got the M8 it sometimes works well, and sometimes it doesnt and looks very fake. I find the best results are to reduce the amount of blurring to whats appropriate for the FL and scene. This examples seems to empoly max blurring and doesnt look like what a real life lense would produce in such a scene. No lense goes from in Focus to Max blur in such a basic 3 dimensional scene. Reducing the blur will assist in hiding the fall off between In focus and OOF that doesnt exist here.

No, it doesn't work any better than the pure software solutions from Nokia Or Sony, for example. Its advantage is that it takes the image in one shot and doesn't need a series like the aforementioned. I tested it quite comprehensively in the linked review.

Instead of trying to measure DOF by using a secondary camera, HTC may have had greater success by using some sort of Laser distance measuring system where there secondary camera sits.
