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.

  Traditional cameras—even those on the thinnest of cell phones—cannot be truly flat due to their optics: lenses that require a certain shape and size in order to function. At Caltech, engineers have developed a new camera design that replaces the lenses with an ultra-thin optical phased array (OPA). The OPA does computationally what lenses do using large pieces of glass: it manipulates incoming light to capture an image.

  [...] "We've created a single thin layer of integrated silicon photonics that emulates the lens and sensor of a digital camera, reducing the thickness and cost of digital cameras. It can mimic a regular lens, but can switch from a fish-eye to a telephoto lens instantaneously—with just a simple adjustment in the way the array receives light," Hajimiri says.

  [...] Last year, Hajimiri's team rolled out a one-dimensional version of the camera that was capable of detecting images in a line, such that it acted like a lensless barcode reader but with no mechanically moving parts. This year's advance was to build the first two-dimensional array capable of creating a full image. This first 2D lensless camera has an array composed of just 64 light receivers in an 8 by 8 grid. The resulting image has low resolution. But this system represents a proof of concept for a fundamental rethinking of camera technology, Hajimiri and his colleagues say.

  "The applications are endless," says graduate student Behrooz Abiri (MS '12), coauthor of the OSA paper. "Even in today's smartphones, the camera is the component that limits how thin your phone can get. Once scaled up, this technology can make lenses and thick cameras obsolete. It may even have implications for astronomy by enabling ultra-light, ultra-thin enormous flat telescopes on the ground or in space."

  "The ability to control all the optical properties of a camera electronically using a paper-thin layer of low-cost silicon photonics without any mechanical movement, lenses, or mirrors, opens a new world of imagers that could look like wallpaper, blinds, or even wearable fabric," says Hajimiri. Next, the team will work on scaling up the camera by designing chips that enable much larger receivers with higher resolution and sensitivity.

  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.
