iFixit teardown reveals OIS on all three cameras in the Huawei P20 Pro

The team at iFixit has performed its usual teardown on the new Huawei P20 Pro triple-cam equipped smartphone to assess the device’s repairability. The score for the latter is 4/10—which means it’s probably advisable to leave repairs to trained service personnel—but far more interesting to us photographers is the detailed look iFixit got at the Huawei triple-camera setup.

You can see the full teardown here, but the main and most pleasant surprise is that Huawei actually built in more stabilization than their specs revealed.

In the official Huawei specifications, only the tele-lens with 80mm equivalent focal length is listed as optically stabilized, while the RGB main camera and the the monochrome secondary unit rely on the Kirin chipset’s neural processing unit for ensuring sharp images. However, according to the iFixit engineers, all three cameras come equipped with OIS hardware, which makes us wonder if there are plans to activate this hardware via a firmware update at some point in the future.

The image above shows the triple-camera in all its glory. The primary RGB camera is placed at the center of the setup and uses a large 40MP 1/1.7 inch sensor with an F1.8 aperture and a maximum ISO setting of 102,400, on the left you can see the 20 MP monochrome camera with F/1.6 aperture, and the 8MP/F2.4 telephoto is on the right. Next to the triple-camera the engineers have placed the 24MP front unit.

CorePhotonics white paper explains the pros and cons of the triple-camera

A couple of weeks ago, we saw the first announcement of a mobile device with triple-camera in the shape of the Huawei P20 Pro. Gil Abraham, Director Product Management at Corephotonics—an Israeli company that specializes in the development of smartphone camera solutions—has taken the opportunity to author a white paper titled “Triple cameras: Are three better than two?”

The document looks at the evolution of dual-camera systems from the HTC One M8 to current models, such as the iPhone X, and then jumps straight into the challenges and rewards of camera systems that feature a third camera.

Abraham says the main challenges for the design and development of triple-camera solutions are cost, space and calibration, as well as firmware, algorithms and power. Three cameras inevitably need more space than two in the already very close quarters inside a thin smartphone and, depending on configuration, a third sensor and lens can add between $10 and $30 to the device’s bill of materials.

Very careful calibration of the entire setup is also needed in order to avoid any artifacts during image fusion—firmware and algorithms have to be tuned to control three physical cameras that should work as one. Power consumption can also be greatly affected if not all hard and software components work together efficiently.

In the final part of the white paper three triple-camera configurations are presented in detail, and their pros and cons explained. There is a zoom camera for low-light conditions and a fish-eye zoom that offers focal lengths from fish-eye to tele. It’s the third variant, however, that we really hope to see on a production device very soon.

Huawei P20 Pro hands-on: 3x zoom lens leaves the competition behind

The P20 Pro is Huawei’s latest flagship smartphone and, at least in the camera department, arguably the most innovative mobile device we have seen in quite some time. The camera module was developed in cooperation with Leica and is the first to combine three sensor/lens modules:

  • A large 1/1.7-inch RGB sensor with Quad-Bayer structure in the main camera is designed to capture as much light as possible and keep noise levels low.
  • A secondary high-resolution monochrome sensor provides depth estimation for the simulated bokeh effect, helps with digital zooming at low magnifications and improves detail and noise levels.
  • A dedicated tele-camera with an equivalent focal range of 80mm springs into action at 3x or higher zoom factors.
The Huawei P20 Pro camera combines three cameras: The main module is at the center, the monochrome camera at the bottom (left in this image) and the tele at the top (right).

So the spec sheet looks impressive but is the Huawei P20 Pro the best camera smartphone money can currently buy? We had the opportunity to shoot with a Huawei P20 Pro for a few days. Here are our first impressions.

Please note that the camera software on our test unit is not final, so some improvements can be expected for the production version.

Key specifications:

  • Triple-camera, 10MP output size
  • Main camera: 1/1.7-inch 40MP Quad-Bayer sensor, F1.8 aperture and 27mm equivalent focal length
  • Secondary camera: 20MP 1/2.78-inch monochrome sensor, F1.6-aperture and 27mm equivalent focal length
  • Tele-camera: 8MP, 1/4.4-inch RGB sensor, F2.4-aperture, 80mm equivalent focal length and optical image stabilization
  • Kirin 970 chipset
  • 6.1-inch Full View display
  • 6GB RAM
  • 128GB internal storage
  • 4,000 mAh battery
