Huawei Unveils Smartphone with Triple 40MP Rear Camera

BusinessWire: Huawei P20 Pro flagship smartphone features triple rear camera and DxOMark Photo score of 114 points:

"The HUAWEI P20 Pro features a Leica triple camera with the highest total pixel count on a smartphone – the camera configuration is comprised of a 40MP RGB sensor, a 20MP monochrome sensor and an 8MP sensor with telephoto lens. It also features an exclusive Leica color temperature sensor for better color reproduction. With f/1.8, f/1.6 and f/2.4 wide aperture to capture crisp, clear details, the HUAWEI P20 Pro also includes a brand new Leica 3x telephoto (VARIO-SUMMILUX-H 1:1.6-2.4/27-80ASPH) lens for long-range photography of up to 5x Hybrid Zoom. The HUAWEI P20 Pro’s highly sensitive image sensor captures low light photos with up to ISO 102400.

The HUAWEI P20 builds on its predecessor’s foundation with a Leica dual camera featuring a 12MP sensor with a pixel size as high as 1.55 μm, and a 20MP monochrome sensor, enhancing the HUAWEI P20’s ability to capture photos in low-light settings.

The HUAWEI P20 Series devices support six-axis stabilization and 960fps super slow motion. With Ultra Snapshot mode, the devices can capture an image in as little as 0.3 seconds by just double clicking the down volume button, even from an off screen.

Key camera data:

  • Triple camera setup
  • Main camera: 40Mp, 1/1.73″ RGB sensor with Quad Bayer structure, f/1.8-aperture lens with 27mm equivalent focal length
  • Secondary camera: 20Mp, 1/2.78″ monochrome sensor, f/1.6-aperture lens with 27mm equivalent focal length
  • Tele-camera: 8Mp, 1/4.4″ RGB sensor, f/2.4-aperture lens with 80mm equivalent focal length, and optical image stabilization
  • Aperture mode default eq. focal length: 55mm
  • PDAF on main sensor
  • 4K video (not default mode)
  • 960 fps slow-motion video at 720p


  1. Is 1.0um pixel in 1/1.73" and 41MP?
    If right, four 1.0um pixels work like 4.0um.
    Why Huawei don't use native 4.0um pixel?

    1. This is a common approach these days. When used at full native resolution, there's significant luma resolution benefits over one larger pixel. But then for low light, with binning it's very close to the performance of the larger pixel.

    2. Oversampling is always a preferable means of obtaining data provided noise is not significantly increased. So you'll get better aliasing performance and it overcomes the inherent blurring of bayer.

  2. More than 100 pts achieved for the first time, congratulations!

  3. Any information on who manufacturers the sensor?

    1. I would like to know that as well but so far no info at all even from Huawei.
