Here's How Qualcomm Will Improve Your Smartphone'southward Camera

Big changes are coming to your phone's smartphone camera side by side year, with Qualcomm previewing an update to its epitome point processor (Isp) that will better support features similar face recognition and mixed reality.

Qualcomm's Spectra Internet service provider is a role of the Snapdragon system on chip that'south a popular mobile processor platform for many Android phones. While the next major Snapdragon update won't arrive until next year, the changes planned for the Spectra ISP have major implications not simply for the cameras on 2018 Android phones only for virtual- and augmented reality headsets equally well.

That'southward because the next version of the Spectra ISP introduces a new architecture to back up advances in image quality, image recognition and ability efficiency. Specifically, Qualcomm is promising that its new photographic camera module will feature improved biometric sensing for detecting people's faces and back up for depth sensing that can power mixed reality features for smartphones and headsets.

New Camera Modules

To that end, Qualcomm is adding iii modules to its photographic camera setup — one for iris authentication and a pair that add passive and active depth sensing.

The iris authentication module provides e'er-on security that can support phone unlocking features. Qualcomm says the sensor volition be able to work in low light and through most sunglasses. If iris authentication works equally promised, y'all won't exist able to fool it with pictures of optics or fifty-fifty 3D molds of faces.

Iris scanning is becoming an of import feature on mobile devices, and non just as a mode to augment other security features like fingerprint unlocking. Every bit smartphone screens have gotten more than expansive — retrieve Samsung'due south Galaxy S8 or LG's G6 — smartphone makers take had to remove concrete home buttons from the front of their phones that could double as fingerprint readers. Improved iris scanning gives those devices another fashion to securely unlock a phone that saves users from having to fumble to find an awkwardly placed fingerprint sensor on the rear of the device.

All About Depth Sensing

Information technology's the pair of depth-sensing modules that have even greater implications for next twelvemonth's phones and headsets, though. Depth sensing drives a number of unlike features like improved image quality on bokeh effects for photos, more powerful mixed reality apps and meliorate facial scanning.

The passive depth sensor Qualcomm's adding volition use differently placed cameras to capture two different images of the same object. By calculating the disparity between those images — the larger the disparity, the closer the object — the depth sensor can determine how far away that object is.

Qualcomm plans to include the passive depth sensor on what it calls "Snapdragon value tier devices." That means depth-sensing will be available to more modestly priced phones in 2018, only as dual rear cameras found their manner into mid-tier and budget phones this year.

Just passive depth sensing has its limits. It doesn't piece of work so well in low calorie-free which tin result in a noisier prototype map. It too has trouble in rooms where the walls and floors don't accept a pattern.

That'due south where the agile depth-sensing module comes in. That module uses infrared illuminator and camera to collect information almost an object, collecting more than x,000 points of depth to create a high-resolution map that can be manipulated in existent-time. Qualcomm says its module tin can observe changes in depth equally small as 0.1 mm autonomously.

To show how that works in exercise, Phillip Jacobowitz, Qualcomm'southward atomic number 82 on camera product marketing, showed me footage captured by the new Spectra ISP of someone playing the pianoforte. The perspective of the image shifted easily from an overhead view to a sideways look at hands hitting the keys; eventually the camera could even prove the hands separating from the rest of the body. That illustrates how this agile depth sensing applied science could be used to assist with hand tracking, Jacobwitz said, eliminating the need for physical controllers in AR and VR. It's also easy to see how the function that kind of imaging prowess could play in instruction and diagnosis.

Other ISP Improvements

Those modules may highlight some of the changes Qualcomm has planned for its ISP, simply they're not all the enhancements on tap for the next version of Spectra. If you lot shoot a lot of video on your phone, y'all'll appreciate Spectra'due south support for motion compensated temporal filtering (MCTF), which volition permit for sharper images of moving objects, even when the photographic camera itself is moving. Jacobwitz showed some other video, this i of a busy urban center street festooned with lights shot from a drone. The footage captured with MCTF support had less noise, and so it was sharper and more than colorful, with even background details visible in the low light.

Other features planned for the second-generation Spectra Internet service provider include accelerated electronic image stabilization, machine learning-powered confront detection and simultaneous localization and mapping that will aid AR and VR programs.

We'll have to await until next year to larn about all the new features in the Spectra ISP and the side by side-generation Snapdragon processor it will ship with. But from what Qualcomm has shown off so far, expect mobile photography to make a big spring in 2018.
