Xiaomi Mi 4 camera spotlight: one of the first with Sony’s new 13-megapixel IMX214 sensor, demo images show it off

Xiaomi unwrapped the Mi 4 at a huge event earlier today, and while the release date is still a few weeks away (unfortunately, the Mi 4 will not be officially sold in the United States and in Europe just yet), details about the 13-megapixel camera have already surfaced.

The Xiaomi Mi 4 comes with a 13-megapixel main camera with a wide, f/1.8 aperture. The exciting news, however, is about the camera sensor: the Mi 4 is one of the first phones to feature the new Sony IMX214 sensor (a BSI stacked CMOS sensor with a 1/3.06” size), a huge step up in the photography department over the last-gen IMX135 used in flagship devices like nowadays (phones like the Samsung Galaxy S4, LG G3, LG G2, etc).

The new Sony IMX214 sensor brings better sensitivity and less color crosstalk

There is a long list of advantages that the new Sony IMX214 brings over the IMX135: it comes with better sensitivity (important for low-light photography), less color crosstalk (so that pixels of one color, say red, don’t get mixed with pixels of other, say green) and significantly improved real-time video HDR.

The big breakthrough is in the speed of HDR - while earlier, it was ill-advised to shoot an HDR of a moving object (the HDR was too slow, and it’d result in a blurred image), the Sony IMX214 is capable of recording 30 frames per second HDR thanks to a new SME-HDR technology. Not just that, though, thanks to improvements in backlight, the camera module is slimmer than the IMX135.

Specifically, in the Xiaomi Mi 4 camera implementation, we have a 13-megapixel shooter that is fast, capable of locking focus in just 0.3 seconds. Last-generation phones like the Mi 3 (but also devices like the Galaxy S4) took 0.6 to 0.8 seconds to achieve focus, which might not sound like much, but is more than enough to miss an impromptu smile that makes the moment special. The Mi 4 comes with a new closed-loop focus system that enables this speedier auto-focus acquisition. The difference comes in the amount of physical movement required to focus - it’s much quicker on the Mi 4.

The Mi 4 camera has also improved its low-light shooting with flash - it takes a flash-less image along with one with flash, and combines them to get both the additional light on the subject, but also the more natural colors of the flashless shot. The Mi 4 also has a post-capture image refocus mode.

For video, the Mi 4 records at up to 4K at 30 frames per second, plus it supports real-time video HDR.

The front camera on the Mi 4 is an 8-megapixel one with a smaller, Sony IMX219 sensor of 1/4" size. It comes with an equally fast f/1.8 lens, with a wide, 80-degree field of view. Xiaomi employs its usual (a bit gimmicky) age and gender recognition, and ‘beautifies’ your images by softening the skin tones and you can pick how aggressively will the phone do this. Finally, there are some of the usual filters and effects that you can overlay on top of images.

Overall, the Xiaomi Mi 4 is at the fore-front of the camera race - it has the latest Sony IMX214 sensor that we expect to see in many upcoming top-shelf devices, and with a few tweaks here and there, it has the potential to be a great cameraphone.

Sony can never get their own cameras right but can for others. I'm a Sony fan btw. Hate how Sony screws up their own cameras... Please step up your game Sony!

They stopped caring after the Arc S.

Sony: Nah let them make good with our sensors, they'll buy millions of modules from us.

Sony fails in software department. 20mp camera on z2 can't even match the details produced by 13mp camera by other OEM's (Camera Software), the details are to soft for mylikings and those are not limited to z2 other xperia's also suffer from same.

the worst thing is, people still believe that z1 and z2 camera is better other phone,just because of 20Megapixel

when people will starting know that megapixel is just number,not quality?

do u know when u see difference btw pixels ?
when u streaming video over network actual live ...
i compared front camera iphon 5 and my android phon with 5mpx and it looks much nicer on 5 mpx.. but obviously when taking picture there are other more things which changes quality ..
but as i said comparing mpx it needs streaming camera over network
with skype or tango or other apps supporting video calls ..

Awesome. Other OEMs make good use of Sony's sensors which Sony cannot do.

I wish that Xiaomi kind of manufacturers bring down proudy and greedy OEM's (Shameshung, ipple, Sony) and show them what is real value for money?

The sensor size is still small. That is great that the overall picture quality is improving but I need pictures that are actually great on the pixel level and not ones that just look good when not zoomed in. I welcome any improvements though.

I'm disappointed in the camera on the Lumia 1520, if only because I have been completely spoiled by the results from my 1020, 808 PureView, Nokia N8 and Nokia N82. The 1520 just doesn't deliver clarity like those devices.

I hope the next imaging flagship form Microsoft Mobile combines the brute hardware power of the 808 PureView with the slickness and algorithms of Nokia Camera. The 1020 was close but still less of a technical marvel compared to the 808.

I don't have high hopes though as Microsoft will probably go for a slim model, weak xenon like the 1020, leaving out the ND filter and having a smaller sensor than the 808 again.

This phone is perfect only if it had sd805. Because they make 1 flagship per year .

Doesn't the One Plus one use the same sensor from Sony?

the oneplus uses this sensor. and the apple is using the 220, an upgrade to the 214. i don't see what the big deal is.

That's the iPhone 6 rumoured sensor and it is not even released yet so yup. But you are right about the OPO sensor though

I think the OnePlus One and the Oppo Find 7 also have the IMX214 sensor.

thanks a lot, I was wondering the same thing. Oneplus One, Oppo Find 7 and LG G3 use IMX214. The person that wrote this article dis not get his facts right.

G3 uses the same as the G2, IMX135. Refer to article.

you guys do realize that most (if not all) of these pictures are fake right?
how come the 2 first pictures can blur the background that much at that distance?
and the front facing camera also have auto focus?
i dont think so
stupid Xiaomi dont even know how to promote their products the right way
