Computational Photo Chips in Huawei Smartphone

Posted by Sam Churchill on

Huawei’s new Honor 6 Plus features a dual camera on the back and sub-$400 price tag, at least in China.

The Honor 6 Plus is equipped with two rear shooters, dubbed “Symmetrical dual camera technology“. The rear camera can take 13 MP shots, but actually consists of two 8 MP sensors with huge 1.85 micron pixel size, and a dedicated ISP tasked with merging and interpolation. One of the cameras features an f/2.0 autofocus lens, while the other sports f/2.4 and fixed focus.

Huawei claims 0.1s focusing time – the use of two sensors with two lenses allows more light to be gathered and improves focusing speed.

The Honor 6 Plus features a 5.5″ 1080p display, 1.8 GHz octa-core Kirin 925 chipset, 3 GB of RAM, a microSD slot for expansion, and a 3600 mAh battery along with a dedicated image signal processor (ISP).

The HTC One (M8) also has a Duo Camera system, but HTC uses their second, 2-megapixel camera for depth of field information. The sensor analyzes the distance and position of elements within a photo, and generates a depth map, which is embedded within each photo.

Computational photography chips such as the Movidius Myriad 2 aim to bring high-end vision and computational imaging applications to smart phones with features such as melding still and video panoramas, real-time HDR, synthetic zooming, depth perception and other features. Movidius claims that using its technology adds less then $10 to the cost of a mobile device.

H.265 encoding, available on Qualcomm’s 810 smartphone processor can reduce HD bandwidth by 50%. Portland’s Elemental Technologies can do the number crunching in the cloud, which could bring real-time computational video to all manner of devices. SpaceCurve continuously fuses geospatial, sensor, IoT, social media, location, and other streaming and historical data while making the data immediately available for analytics.

OpenVX provides mobile developers with an industry standard API to deliver embedded computer vision and computational imaging chipsets that can keep UAVs on track.

The Honor 6 Plus will be up for preorder as soon as tomorrow from the Huawei mobile shop, with shipping starting a week after. Pricing is pegged at 1999 yuan (~$323) for the 3G version, and 2499 yuan (~403) for the 4G LTE one. No word on availability in the United States, but expect a bunch of smart phones with computational chips that feature synthetic zooming and other features next month at CES in Las Vegas.
