How AI drives Huawei Nova 5T

The new Huawei Nova 5T smartphone uses various AI techniques to capture photos that are claimed to produce better photos than SLR cameras, in some conditions.

The Huawei Nova 5T incorporates a quad-camera array on the rear, comprising a 48MP HD lens, 16MP wide-angle lens, 2MP macro lens, 2MP bokeh lens and 32 MP selfie Superstar lens, with AI technology and advanced beautification algorithms. This means that, among other, it balances exposure under all lighting conditions and in scenarios ranging from vast landscapes to close-ups.

Early adaptations of beautification algorithm technology resulted in every image being treated with the same adjustments, often resulting in the image appearing obviously fake, or applying an extremely pale skin tone to the subject. The current AI beautification algorithms on the Huawei Nova 5T, however, contour a specific face shape based on individual features. By operating with the Kirin 980 chipset’s dual NPUs, the AI system is able to tailor the beautification influence on the image, avoiding a caked-on appearance and accentuating the user’s characteristics.

Another drawback of many smartphone cameras is that the contrast between the brightest and darkest areas can prove difficult for even a professional SLR camera to capture effectively. However, with the 5T, multi-frame synthesis is deployed for backlit scenes that snaps a number of images in one shot.  The system then merges the best parts of each shot to form one final photo, in which the dynamic range is effectively widened, and image contrast, sharpness, and quality are substantially enhanced. This ensures images with ultra-clarity definition and enhanced sharpness and detail, down to the finest of hair strands.

The embedded technology combines AI-fuelled image semantic segmentation and partition optimisation technology via the lenses. The handset’s AI-powered cameras also lay the groundwork for optimal video shooting effectiveness, with settings such as AI Image Stabilisation (AIS), Auto Exposure Lock (AEL), and Auto Focus Lock (AFL) technologies working together. It comes equipped with an automatic video editing feature that is suitable for novices and brings simplicity to the video editing process. The camera has the ability to recognise recurring subjects in videos, thus saving the user the hassle of sorting through clips, by creating edited subject-based videos.

AI also assists in applying auto-beautification for the subjects in video clips. Developing this technology required substantial trial and error, including testing on approximately 60,000 models before the beautification effects were fine-tuned. Over the course of this process, Huawei developers took into account factors such as brightness contrast, inactive blur, saturation, as well as advanced photography composition principles.

The Huawei Nova 5T’s Kirin 980 chipset is equipped with dual NPU computing, resulting in the ability to cipher advanced algorithms. This AI-powered colour results in the camera capturing and keeping the colour of a subject in a video, while applying a greyscale background to the image, and thus giving it the appearance of leaping off the screen.

This smartphone comes pre-installed with all Google apps and Google Play Store.

The Huawei Nova 5T comes in two colour schemes – Crush Blue and Midsummer Purple. The smartphone is available on contract from the following service providers:

  • Vodacom – R599 Smart XS+ Plan
  • MTN – R599 MFMXS Plan
  • Telkom – R599 FREEME 1GB Plan
  • CELL C – R619 Pinnacle 2G Plan

Nokia 7.2 gets triple camera system

The latest handset from Nokia packs a 48MP triple camera system with Zeiss optics, as well as a PureDisplay screen.

Published

on

HMD Global, maker of Nokia phones, has announced the Nokia 7.2, the first Nokia smartphone to combine a triple camera and PureDisplay. It features a 48MP triple camera with Quad Pixel technology and Zeiss Optics. It also introduces a range of Zeiss bokeh styles, exclusive to Nokia smartphones, that recreate the way legendary Zeiss lenses produce high visual impact and signature blur. 
Alongside more AI-powered features such as night mode, users can get more creative with their photography. Building on the strengths of its predecessor, Nokia 7.2 combines PureDisplay technology and always-on HDR.

Shaun Durandt, GM of HMD Global Southern Africa, says: “With the Nokia 7.2 we aim to push the limits on what consumers can get from one of our popular Nokia 7 series smartphones. The Nokia 7.2 offers consumers advanced tools to express their creativity. Everything from the Zeiss Optics, exclusive Zeiss bokeh modes and powerful AI imaging, to its breath-taking PureDisplay technology, makes the Nokia 7.2 a device that truly stands out. In combination with the beautifully patterned satin glass back, Nokia 7.2 packs design innovation and stunning imaging performance, with a two-day battery life, into a smartphone for aspiring creators across the world at a truly incredible price.”

Nokia 7.2 is the first in the Nokia smartphone portfolio to feature a triple camera set up with Zeiss Optics. This is a combination of a highly sensitive 48MP sensor with a Quad Pixel technology main camera with ZEISS Optics, an ultrawide camera and a depth camera. The Quad Pixel technology combines four pixels into one for enhanced images in most conditions. 

The new bokeh styles include a portrait mode, which uses powerful image processing to recreate the way Zeiss lenses produce high visual impact. These blur effects are called Zeiss Modern, Zeiss Swirl and Zeiss Smooth modes. Add beautification to improve skin tones for instantly shareable portraits. AI-powered night mode allows users to capture the moment in low light, combining image fusion and explosion stacking to deliver good low light performance.

It comes with an ultrawide camera, which has a 118-degree field of view that means users can fit a lot more in one shot. The selfie camera also features Zeiss optics with a 20MP.  

With a dedicated Pixelworks visual processor, Nokia 7.2 upscales video content to HDR quality in real-time, with up to a billion shades of colour, higher contrast and expanded dynamic range. This means users can enjoy more contrast and deeper colours when watching TV shows, compared to other displays.

Crafted from polymer composite that is twice as strong as polycarbonate and half the weight of aluminium, the device is light, yet super strong and rigid. 

Nokia 7.2’s light-diffusing satin glass back honours the Finnish glass making heritage and results in a premium finish. Using a multilayer coating system with vacuum metallisation, the result delivers bright colours, a smooth finish and offers durability. 
Powered by the Qualcomm Snapdragon 660 Mobile Platform, the device offers balanced performance, making sure the phone is ready when users need it the most. The Nokia 7.2 also comes with the signature two-day battery life promise.

As part of the Android One partnership, Nokia 7.2 is Android Q ready and will receive guaranteed monthly security updates for three years and OS updates for two years, so it is claimed to get better performance over time.  
Pricing and availability

The Nokia 7.2 comes in Charcoal and is available at Vodacom stores on 20 November from R6,299.
