Xiaomi Teams Up with Light for Multi-Module Smartphone Cameras
Xiaomi and Light, a computational imaging firm, have announced at Mobile World Congress that the two companies will be working together to develop new multi-module cameras for smartphones. The two companies promised that the jointly-developed cameras will feature DSLR-level capabilities, but did not disclose when the first product from the joint project is expected to come to fruition.
Light specializes on computational imaging solutions using multiple camera arrays. The company has gone so far as to develop their own chip that can work with 6, 12, or 18-camera arrays. And while Xiaomi and Light aren't specifying just how big of a camera array they're looking to develop, we're likely looking at something in the lower-bounds of those number, if only due to the limited size of smartphones. For reference's sake, a 6-module camera would be very similar to what Nokia has done for their Nokia 9 PureView.
Cover the entire back of a smartphone with cameras, then gingerly hold it using the corners.

Phased array on a smartphone is a completely idiotic idea. First, you aren't going to phase it in any stable fashion in that form factor because you'll need to combine the beams, and you're not doing that in a thin smart phone. Plus, let's say you do phase them, what are you gaining? You effectively now have the resolution of a lens that is the width of the phone, but only in that one dimension. And you've thrown out all your signal because though you have an effective aperture that is the size of whatever circle you encircle the two lenses, you have the photon collection efficiency that is the ratio of the areas of the lenses to the area of the effective aperture. Kind of get the worst of all cases.

They are either hyping it up or they genuinely think it can be used in smartphones at some point. I wouldn't rule this technology out just yet.

You can tell that that's been written by advertising copywriters. To get DSLR-level capabilities you need an actual DSLR, big glass, big sensors. Claiming you can get DSLR-level performance from a tiny fixed lens and equally tiny sensor on a cellphone is the same as claiming you can get Wharfedale-level performance from a tiny sound bar. You can try really, really hard to fake it, and under just the right conditions with just the right audience marginally pull it off, but the rest of the time you are just faking it.
