These Huawei cameras seem to produce 12 megapixel final shots, so the colour isn’t upscaled to 20 megapixels. I’m guessing the monochrome is used as a processing template to sharpen and increase clarity within the 12 megapixel shot, and to provide raw material to allow improved processing on such effects as reduced depth of field. That provides increased – the word of the moment! – “bokeh” effect. “Bokeh” is the shape assumed by out of focus highlights.
Again I’m guessing, but the focus functionality using the monochrome sensor is also likely improved.
Huawei has provided a bunch of photos from professional photographers to demonstrate what a fine job these devices can do. I’d note that there might be some element of professional expertise involved in the creation of those shots, in addition to the technical excellence of the phone cameras.
Back to the phones
But of course, they aren’t really cameras with phone functionality. They are really Android phones with excellent cameras. They are powered by octacore Kirin 960 processors (up to 4 by 2.4GHz and 4 by 1.8GHz), run Android 7.0 Nougat with Huawei’s EMUI 5.1 skin and have 8 megapixel f/1.9 selfie cameras. And they have a fast charge capability.
The P10 has a 5.1 inch 1080 by 1920 display with Corning Gorilla Glass 5, 4MB of operating RAM, 64GB of built in storage, expandable memory via microSD (to 256GB) and will sell for $899.
The Huawei P10 Plus has all of that apart from several upgraded elements: the screen is 5.5 inches and 1440 by 2560 pixels, it has 6MB of RAM, 128GB of storage built in and will sell for $1099.
Both will be available on 25 May 2017. The P10 comes in black, gold or “Dazzling Blue”, depending on the vendor. The P10 Plus is in “Graphite Black” only.
