Huawei shares P20 triple-cam teaser videos

We are getting close to the launch of Huawei’s upcoming flagship P20 smartphone on the 27th of March, and thanks to a number of leaks we’re already fairly certain that the new device will come with triple cam setup, offering a total resolution of 40MP and a 5x optical/digital hybrid zoom.

Now Huawai itself has started teasing the new model with a couple of videos on its YouTube channel.

The first one, called “See Brighter” (above), teases the smartphone’s low-light capabilities. It features a “pro” photographers with a DSLR and huge assortment of lighting gear next to a P20 user who is happily snapping away in the same lighting conditions without any additional equipment.

The second video (below) is titled “See Closer”, hinting at the P20’s zoom capabilities. It follows the same scheme as the first clip, showing a DSLR-photographer shooting with a selection of heavy prime and zoom lenses, next to a smartphone user with triple-cam-equipped Huawei P20.

If the teasers are anything to go by, the P20 could combine a “regular” RGB image sensor with a high-resolution monochrome chip for improved low-light performance and digital zooming, and another RGB sensor with a longer lens for optical zooming. And if Huawei’s engineers can manage to merge image data captured by all three sensors in an efficient way, the P20 could be the mobile camera to beat in 2018.

Sony is working on high-sensitivity dual-camera setup

If you were hoping for the new Sony Xperia XZ2 models to feature a dual-camera setup, you were disappointed. Sony is by far the largest maker of image sensors but the Japanese manufacturer’s own smartphone models still have to make do without the dual-cam technology that has almost become a standard on high-end devices.

That said, there is a good chance the wait for a Sony-branded dual-camera smartphone might be worth it. Sony executives told us the company was working on a dual-camera solution that would allow for low light shooting with ultra-high sensitivities – ISO 51200 in stills mode and ISO 12800 for video.

A test scene with extremely low illumination inside a black box is used to demonstrate the performance of the the dual-cam prototype (top) compared to a current model (bottom).

No further technical detail was provided at this point but given the camera module will be powered by a new “Fusion” Image Signal Processor, it’s fair to assume the high sensitivities will be achieved by some kind of computational imaging process, merging image data captured simultaneously on the two sensors of the dual-camera.

This is not a totally new concept – for example Huawei is merging image data from an RGB and a monochrome sensor on some of its dual-camera models – but given Sony’s bold high ISO claims there is a good chance its engineers have found another secret ingredient to boost performance to new levels.

Sony claims the new system is pushing smartphone low light performance into ILC territory.
