More details about HTC One (M8) Duo camera surface

The HTC One (M8) is the first handset to feature a novel, ‘Duo’ camera setup with two rear cameras working in concert to add a layer of new, computational effects to your images. You probably already know about the effects that you can achieve with the new handset - things like post-capture selective focus (the UFocus feature) with its added ‘bokeh’ effect, the foregrounder and sketching features, as well as the parallax effect you can add to pictures. Now, however, AnandTech took an even deeper dive in the minutiae of the cameras on the new HTC flagship, discovering some interesting subtleties and details.

First, we ought to remind you, that the new One (M8) uses the same UltraPixel technology as the original One (M7) from last year. That is to say, it uses a 4-megapixel camera with a much-larger-than-average 2.0µm pixel size. Going back to the original one, HTC had to use two suppliers for its UltraPixel camera - ST Microelectronics with its VD68969 sensor and OmniVision with the OV4688 camera sensor. Interestingly enough, the new HTC One (M8) seems to have switched to using the OmniVision sensor exclusively. Speculations are that there were quality control issues with the ST Microelectronics sensor, and that’s why HTC went full-on with California-based OmniVision, but one never knows what the actual reasons are.

What’s even more fascinating, though, is that Anand found out what the secondary camera (the one on the top) in the ‘Duo’ setup is. It turns out that HTC is using the front facing camera sensor from the HTC One (M7) as a depth camera in the M8. The same 2.1-megapixel OmniVision OV2722 1.4µm, 1/5.8" sensor sits right atop the main ‘UltraPixel’ module.

Digging further, it is revealed that pictures captured with the ‘Duo’ cameras turn out 60% larger than images shot on just the UltraPixel camera alone. Anand theorizes that this is due to the fact that the second camera captures not just depth information, but also a stealth image used for the effects (we are saying stealth since it is not something that can be seen in the gallery app). Moreover, estimations are that 40% of that additional image information comes from the image shot on the secondary camera and the remaining 60% - from depth information, again captured from the secondary camera.

Finally, it’s worth mentioning that the secondary camera in the Duo camera setup does not always work. In very low-lit conditions, as well as in macro photography, the secondary camera just won’t fire - you will still get a picture, but just from the main UltraPixel camera. All in all, this adds even more clarity to the new camera technology used in the HTC One (M8). You can take a look at our Duo camera samples below: how do you like what you see?

You know why? Because Google forces Youtube users to use Google+. And everybody hates it.

This bokeh effect from the All New One is kind of a fail... From the flowers pic, the effect seems to blur even the carriage in the backgroung from Pic#3... I say the phone is having trouble in figuring out the depth in the picture and doesnt know which is where... Not that this cannot be correct.. This effect brought purely from the software side so it is gonna be easy to correct...

U know how HTC is, they release it then they find out that ppl have complaints about their software. A software fix is being downloaded then it really does fix it. That's HTC for ya

Meh, I reckon the Duo camera is just another gimmick
Very disappoint they remove OIS for the Duo camera
I would choose OIS over Duo camera any day

So much for HTC saying we are not into gimmick, when the duo camera is a gimmick. HTC is misguided in thinking that having a phone that can refocus is better than just upgrading the M7's camera to 6 or 8 megapixels.

Why HTC whyyyy????!!!!?????You could have been the king in 2014,i just don't get them,they could have easily made a killer phone but instead they are behind samsung and son right now.I mean samsung can afford to fool around,the have money,but not HTC.If they used a camera similar like LG and put in 3 GB of ram,and an even larger baterry 3.200 mh this would have been a killer phone.Butt i think the obvious truth is that htc can't afford it anymore,if you noticed they are saving money on every step except design. Same camera and memory as last year slightly better battery...

HTC must be thinking of making Triple Camera on HTC M9 on year of 2015.

So does this effectively mean that HTC combines the resolution to achieve something similar to a 6MP camera?

Same thing I was wondering.

So can I get 6MP+ images with the combined cameras?
