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!

The Galaxy S4 trumps the G2 anyday in day light and brighter conditions.. It has been proven that the GS4's camera still lives up to today's smartphone standards and in no means inferior. Talking about dimmer conditions, the G2 may provide a brighter image overall but the S4 isnt behind, it takes comparable pictures to the G2.

G2 camera have terribly slow focus, and it is blurry in low light. It is great in perfect conditions. Nexus 5 can take better photos with HDR+ (in the low light)... So G2 is more marketing then real useful camera... I have try it. And when I say that nexus 5 HDR+ is much better then any g2 mode, I mean this link: :) plus.google.com/u/0/b/113972598262899933011/explor​e/nexus5photography

Really incredible, I can't believe they manage to put "Phase detection autofocus" system in mobile camera!!!! O_o - this is really breakthrough!! I don't like samsung devices because of crappy Touchwiz, but this is something special! Still, I wouldn't love to own a S5, but I would like to try this camera for few days. :) To bad they didn't put OIS in camera :/

So basically the GS5 has the best of everything for a smartphone: Best camera, battery life, display and performance. It IS the best smartphone, maybe until the Note 4 comes out.

It's not even better than S4 or Note 3. Imagine G2. The samples that I saw showed very noise pictures and some pictures with excessive bright. In the theory, even HTC has a beautiful one but only in the paper. When we see the pictures we see the results.

There are not much HTC fanboys here . Those are mostly iboys pretending to be HTC "lovers", to fight against Samsung, and to promote the aluminum "suprimacy" .

That exactly how i fell Ashoaib :p. 4/4s had a really nice buildquality :) 5/5s feels cheaper.

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

*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.

S5 use the better version of S801(not only overclocked). Check it out. Check also what Wi-Fi tech use S5.

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

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.

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"
