SAMSUNG GALAXY ALPHA MEGAPIXEL

Camera: 12-Megapixels... Downscaled?

The main camera uncovered on the samsung Galaxy Alpha is a 12-megapixel CMOS through ISOCELL technology, combine with bei f/2.2 lens v a 35mm-equivalent focal length des around 31mm. Aside from the resolution, the camera is similar to die one found bei the Galaxy grad 4 and Galaxy S5 (both 16-megapixel shooters) together it too features a aboriginal 16:9 aspect ratio.

Oddly, samsung has gone zu quite an effort kommen sie obscure die camera sensor modell found in the Alpha, making that hard kommen sie discern any kind of extra specifications. Both die S5 und Alpha have the same focal size (4.8mm) and same field des view, describe both sensors are ns same size. This means one von two things: either ns pixel size has increased native 1.12µm zu around 1.3µm; or ns sensors space literally the same, with samsung downscaling every 16-megapixel native capture to 12-megapixels an pre-processing.

While I’m notfall completely convinced, I believe the latter is more likely. Ns Alpha virtually always uses die same ISO und shutter rate as die Galaxy S5 wie man capturing a specific scene, and as die photos native both phones look very similar, there ist no indication von better low-light performance from ns Alpha due kommen sie larger pixels. Furthermore, downscaling a photo taken with the Galaxy S5 kommen sie 12 megapixels looks strikingly comparable to die same photo caught with in Alpha, as you kann see below. Klasse that ns Alpha deshalb appears to apply an extra sharpening filter, creating tell-tale post processing artefacts.

This hypothesis zu sein backed up von two other pieces des information. One ist that neither samsung nor Sony (the usual sources zum flagship Galaxy cameras) create 12-megapixel smartphone sensors as much as I tun können ascertain. The other zu sein that when i was digging around in the Alpha’s camera firmware diagnostic tool, it indicated ns sensor was the same S5K2P2 modell as found an the S5. The diagnostic device isn’t always the most reliable source, yet it does offer some insight to die camera hardware.

So at this stage I’m tentatively saying that die Galaxy Alpha package a 16-megapixel 1/2.6” S5K2P2XX CMOS sensor with a pixel size of 1.12 µm, downscaled zu 12-megapixels in the camera firmware. This 25% reduction in image size boosts sharpness when looking punkt full-resolution crops, which can be Samsung’s on purpose with ns odd choice of downscaling (if I am correct).

As zum image quality, die Galaxy Alpha produces bild that are very similar to ns Galaxy S5 (surprise, surprise). Metering isn’t always identical, however you can usually depend on ns Alpha zu produce balanced images with great dynamic range and fantastic color accuracy, especially in strong sunlight. Even though photos space 12 mp rather 보다 16 MP, there’s still room to manipulate them, und overall sharpness is marginally better compared to ns S5.

The f/2.2 lens on die Alpha zu sein optically fairly decent, transferring acceptable bokeh weil das a smartphone. Choose other luxury Galaxy devices, the Alpha comes v a selective emphasis mode that can introduce simulated background blur, though its implementation is ausblüten far indigenous perfect.

While you’ll generally get great photos in good lighting, die lack of in OIS module method that an less than ideal conditions bild won’t be together amazing. Comparing bild from the Alpha und the grad 4, die latter des which comes through OIS, reflects that die Alpha’s images aren’t as bright or as crisp. Sometimes you’ll obtain photos that room slightly blurry due kommen sie shaking hands, although shade quality is ausblüten quite good.

Keeping the bild stabilization attribute activated enables you zu take part acceptable images bei low light. Die Alpha ist certainly notfall as qualified as a competing smartphone with OIS prefer the note 4 or LG G3, but many photos taken punkt night kann be usable. Zum times wherein it’s simply auch dark, the angeführt flash can help zu illuminate the surrounds, although like most smartphone flashes it’s limited in range und brightness.

As the Galaxy Alpha has largely die same software application as ns Galaxy S5, you also get all die same camera features. This includes a very great HDR mode, a handy, mobiltelefon amount of camera settings, number of burst shooting modes, und live effects. An unified with zero shutter lag und extremely schon fast autofocus, and the Galaxy Alpha comes through a really capable shooter.

The prior camera, which is a 2.1-megapixel S5K8B1 1/7.3” CMOS sensor through 1.12µm pixels paired with in f/2.4 lens, zu sein good enough zum the sometimes selfie and some 1080p videos recording. It’s certainly not the best selfie camera i’ve seen, lacking low-light friendly hardware and a wide-angle lens, however it gets the job done most von the time.

The Galaxy Alpha comes through all die same videos recording functions as the Galaxy S5. This method 4K extremist HD video recording hinweisen 30 frames von second, smooth activity 1080p hinweisen 60 FPS, und even slow movement 720p punkt 120 FPS. Bitrates space identical, pushing up to 48 Mbps zum 4K utilizing high-profile H.264, a sample of which tun können be found below.

Quality when recording weist 4K, especially wie man downscaled to fit a 1080p or 720p display, zu sein excellent. Every frame looks similar kommen sie a blieb image, with great color quality und fast metering, while audio recording is also very good. Die reduction zu 12-megapixels for blieb images does notfall appear to oase affected video recording bei any significant way.
