Samsung Galaxy S5 camera under the microscope: in-house Samsung sensors make fast auto-focus magic possible

After years of reliance on Sony camera image sensors in its flagships, this year, Samsung is finally ready to ship the Galaxy S5 with its own, in-house ISOCELL sensor that the company claims could be the next key breakthrough for mobile cameras after the arrival of backside-illuminated (BSI) sensors.

BSI camera sensors improved the sensitivity of the sensor hugely, paving the way for higher-resolution (most notably, 13-megapixel) mobile cameras with smaller, 1.1µm pixels. Now, ISOCELL technology builds up on BSI, as it claims to bring another leap in light sensitivity, while reducing noise, and capturing a higher dynamic range.

Chipworks put the 16-megapixel main and the 2-megapixel secondary camera sensor of the Galaxy S5 under the microscope to show what secrets ISOCELL hides, and the images it captured verify that we indeed have Samsung-made camera sensor in the S5.

The main, 16-megapixel camera sensor carries the model name ‘S5K2P2XX’ and features 1.12µm sized pixels. The front-facing 2MP camera has the ‘S5K8B1YX03’ model name, and it also comes with 1.12µm pixel pitch. Chipworks has already showed us a vertical X-ray image of an ISOCELL sensor showing how Samsung is the first to combine advanced features like front deep trench isolation (F-DTI) and Vertical Transfer Gate (VTG) in a mobile camera sensor.

What’s particularly interesting, though, is that Samsung is also one of the first companies to implement phase detection auto-focus pixels that allow the AF mechanism to lock focus in just 0.3 seconds. Indeed, pairs of phase detection pixels are positioned almost entirely throughout the sensor pixel array. 

This is indeed an impressive technological breakthrough - Samsung is the first company to implement phase detection on a 1.1µm pixel array, and moreover - on a BSI sensor. Phase detection pixels are also half-masked, which suggests that Samsung is using a back aperture grid, another first for the company. You can see the images of the brand new Galaxy S5 sensors up-close in personal in the gallery below. Let us know what you think about the Galaxy S5 camera, and stay tuned for our forthcoming full-on Samsung Galaxy S5 review!

Yeah, it sounds good. But overall camera performance still left behind the G2.

The S4 camera is better than the G2. The S5's camera is miles ahead thanks to the 801 and ISOCELL tech sorry.

i heard that some of the s5 samples were actually worse then the s4 in certain conditions, that being said the samples were a pre production unit, will be looking forward to seeing proper comparisons on a final retail model

" heard that some of the s5 samples were actually worse then the s4 in certain conditions" Lie!!!! It was said " some were not better then the s4 in certain conditions"

I would have to agree to this. I had a chance to play with S5 demos at Samsung roadshow. While it did capture impressed amount of detail in low light, there was just too much noise. I'm pretty sure they can tweak the software side of things by retail launch or future updates.

and you used the G2 so much that you got to this conclusion,right!? as a former owner of both the S4 and the G2 i can tell you that the G2 is better in everything....waaaay better... use them first and then spread misleading info if you still can... and in the android realm,the Z1 is for now the camera phone to get...using it right now and it's nothing less than spectacular... use them first...

yes very true,,, any unbiased person could result Z1camera as the best in android...and Z2 has even improved camera over Z1...The Sony G lens 1/2.3" 20.7 mp sensor quality is unmatchable...

i think you are misleading the info... saying G2 camera is 'way better' than the S4 already proved it. Maybe show us some camera samples and explain to me how the G2 camera is 'way better'? And yes i tried both phones, even the Z1 and in my opinion the Z1 is the worst, because alot of shots turns out blurry when compared to the G2 and S4.

I have tried note 3 and z1 together, note 3 is a better performer over all... z1 is not consistant in photo results

Posts: 67; Member since: Mar 05, 2013

just google it...ok.. and trying is not the same with owning and using them day by day...and to say that the Z1 is the worst demonstrates me how much knowledge you have in these things...the Z1 has the biggest sensor put on any android phone ever and it's a Gsensor you know,like in Cybershots with a BionZ image processor and Exmor RS. ...and so on...have you heard of depth of field,bokeh,focus!?!?to say that the S4 is better than this is just a bad joke. i bet that the S4 that you praise so much is even better than Lumia 1020 or 808PW...am i right?! and about the G2,just check reviewers on Youtube if you don't believe my words...or with the users of that phone... fanboys...gotta love'em! so long,'cause i dont have time for these useless discussions...

In the blind testing the G2 camera came on top:http://www.phonearena.com/news/Nokia-Lumia-1520-tops-our-blind-camera-comparison-while-Nexus-5-ends-up-last-HTC-One-M8-finishes-sixth_id54561 About the S5, I would tend to thing it´s going to be better, but I´ll wait for the reviews

Lol. Even SD 805, 850, 855, 890 or whatever will never help TouchWiz from massive lags. Speed on autofocus doesn't mean the S5's camera is better than its competitors.

As much as i like G2.. no. The camera is not better.

Best ever display for a smartphone, best battery life ever, best groundbreaking camera technology... Wow, Samsung is getting serious and all of this without any overstated advertisement about it... Cool and classy !...

LG G3 sounds good ! But lets wait for the Samsung K Zoom and production photos from S5. I want something better than my Note 3 , and in pair with my Nokia 808 to upgrade.

I'd take this over the dual 4 Ultrapixel cam and run-of-the-mill 20.7MP shooter.

Its still no match to the monstrous duo ultrapixel 4mp camera.

Yeah man. That set up is amazing. It even manages to make any phone that uses it as tall as a phablet. Pretty impressive stuff. Monstrous is a good way to put it. Lol

I dont think its a sarcasm... it is quite right... but the look of m8 is so beautiful that it doesnt matter

ALUMINUM!!!!!!!!!! We don't want best camera, best displey ever, best Wi-Fi , best SoC, best battery life, best dust proof.... We Want ALUMINUM

*sarcasm on* Personally, I just want huge bezels...because bezels are so, hmm, thick and comfortable.

How does the S5 have the best wifi? It and the HTC One M8 both have the same wifi 802.11 a,b,g,n,ac 2.4 and 5 ghz. They both also use a Snapdragon 801 processor.
