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
