The Huawei P20 Pro most definitely has the craziest smartphone digicam enjoy in years, with a triple digicam setup that spits out spectacular effects. The digicam makes use of an 8MP f/2.four lens (3x telephoto zoom), a 20MP f/1.6 monochrome lens, and a large 40MP f/1.eight lens in tandem to produce some technically wonderful pictures.
It’s transparent Huawei used to be closely influenced through 2013’s Nokia Lumia 1020, lengthy held as the excessive water mark for smartphone pictures, and no longer simply because they each tout greater than 40MP cameras both. The P20 Pro tries to resolve a few of the identical elementary cell pictures demanding situations as the Lumia 1020, whilst additionally making an attempt to resolve a subject matter Nokia created for itself. While we already when put next the cameras of the Lumia 1020 and P20 Pro, let’s take a more in-depth glance in what those two telephones have in commonplace.
What did Nokia be offering again then?
Back in 2013, the Finnish corporate had to make do with 2GB of RAM and a dual-core Snapdragon S4 Plus processor. The chipset handiest supported 20MP digicam sensors through default, so Qualcomm and Nokia had to do further paintings to make certain compatibility with the telephone’s large 41MP sensor. Some of this paintings additionally noticed Nokia harness Qualcomm’s personal symbol sign processor (ISP) as an alternative of constructing a brand new little bit of silicon from scratch.
The black magic didn’t forestall there, as the corporate grafted a fancy optical symbol stabilization answer the usage of ball bearings onto the Lumia 1020. Nokia even incorporated a leaflet in the telephone’s packaging, assuring customers the rattle used to be not anything to be curious about.
Microsoft reined in the megapixels with follow-up units. Later Lumia flagships all featured extra conventional 20MP shooters and computational pictures smarts as an alternative.
The identical other people labored on the P20 Pro
It’s a great time for a follow-up to the 1020. Phones have higher sheer silicon horsepower, complicated processing tool, and significantly better digicam sensors. Sure, it didn’t come from Microsoft or HMD Global, nevertheless it’s no longer as abnormal as you might imagine that Huawei launched one of these reminiscent telephone.
The Chinese colossus opened an R&D facility in Finland in 2016 trustworthy to pictures, amongst different spaces. As PhoneArena to start with identified, a number of other people operating for Huawei have their roots both at Nokia or in particular operating on the Lumia 1020. Perhaps the maximum necessary Nokia individual at Huawei is former Nokia and Microsoft imaging head Eero Salmelin, who serves as the director of imaging and video era at the Chinese emblem.

That affect is noticeable. Both the Lumia 1020 and the P20 Pro take a look at to resolve equivalent smartphone digicam issues — even though in several techniques.
A high-res digicam as a method to an finish
Both the P20 Pro and the Lumia 1020 don’t use the high-resolution digicam as a brute-force “look how huge mine is” play. Instead, the 40MP and 41MP cameras ship higher low-res and night-time snaps.
The 1020 popularized the observe of oversampling through the usage of that big 41MP sensor to distil knowledge down to 5MP pictures. The observe necessarily noticed Nokia take the knowledge from seven pixels and mix it into one, leading to decrease decision photographs that typically appeared higher than the standard 5MP snaps. You weren’t going to add 38MP photographs to Facebook anyway, have been you?
It’s one way we’ve additionally observed on Sony’s Xperia Z-series flagships in recent times. Those telephones use oversampling on their 20MP cameras to recuperate 8MP snaps (in concept) by way of Superior Auto mode.
Huawei served up an overly equivalent manner with the P20 Pro. It let customers shoot at both complete decision or at a pixel-binned 10MP. Huawei’s manner in reality makes Nokia’s glance easy through comparability.
“There is pixel binning at a very deep level, resulting in a standard Bayer layout with two green pixels, one blue pixel and one red pixel, all joining to make one single larger pixel. This is accomplished through co-engineering between Huawei and Leica,” the corporate instructed Android Authority‘s Kris Carlon previous this month.
At the most elementary stage, pixel binning comes to the knowledge from quite a lot of pixels being blended, which is basically equivalent to Nokia’s answer.
It’s a pity Huawei didn’t take after the Nokia 808 right here through permitting you to make a choice quite a lot of pixel-binned resolutions, reminiscent of 5MP. Perhaps it’s the structure in their present answer (the usage of 3 cameras), however a 5MP shot may just theoretically accumulate knowledge from 8 pixels as an alternative of 4. Regardless, our reviewers didn’t appear to be complaining.
In all 3 instances (Sony, Huawei, Nokia), the firms are satisfied for you to shoot at the decrease decision. Think of it like a buffet of mediocre meals (the complete decision shot) as opposed to a smaller, tastier dish (the decrease decision snap).
The Lumia 1020 and the Huawei P20 use equivalent oversampling or pixel-binning era, permitting them to necessarily distil knowledge from a great high-resolution digicam right into a smaller picture. The 40MP determine would possibly flip heads, however you surely need to take a look at the decrease decision photographs.
Building higher smartphone zoom
Zoom has all the time been considered one of the hardest demanding situations for smartphones. There merely isn’t enough space in the telephone for the elements required to do it in point of fact smartly.
Nokia’s answer in 2013 used to be to use extra oversampling, permitting you to zoom in up to 3x for 5MP photographs. The oversampling used to be maximum excessive when zoomed out, and steadily reduced as you zoomed in.
A noteworthy answer popped up in 2016 with secondary telephoto cameras (providing 2x zoom), as observed on the greater iPhones. The era briefly unfold to different telephones, reminiscent of the Galaxy Note eight, Xiaomi Mi 6 and the OnePlus 5T.
The Huawei P20 Pro delivers zoomed-in snaps which might be generally higher than typical virtual zoom.
One of the largest problems with telephoto cameras is that they typically be offering horrible low-light efficiency. Huawei made up our minds to use an 8MP f/2.four telephoto snapper on the P20 Pro and fuse knowledge from a number of cameras to ship up to 5x hybrid zoom.
Much like Nokia’s lossless zoom, hybrid zoom is no longer relatively at an optical stage of high quality, nevertheless it beats conventional virtual zoom and holds its personal towards telephoto cameras. However, the P20 Pro sadly doesn’t appear to reinforce hybrid zoom for video, which the Lumia 1020 did, with 1080p photos topping out at 4x zoom and 720p hitting 6x zoom.
Creating higher stabilization than ever sooner than
Huawei makes use of a mix of conventional optical symbol stabilization and its “AI stabilization” era. The corporate claims that AI-driven stabilization is higher than OIS, which sounds a bit iffy whilst you first pay attention it.
Nevertheless, the company argued its level through claiming you have to do hand held lengthy publicity photographs, which historically require a tripod. Our initial trying out of this selection confirmed it indisputably works smartly. Then once more, it sort of feels like the corporate is stacking pictures quite than doing a standard lengthy publicity. Otherwise, the vehicles in the above shot would’ve been unfold out alongside the street, for one.
Nokia’s ball bearing manner used to be a mechanical surprise. The corporate claimed at the time its answer presented up 5 occasions longer publicity occasions than rival cell cameras. But OIS (or even virtual stabilization) has come some distance in 5 years. All the primary avid gamers ship efficient answers now.
Solving the 1020’s largest drawback
The Lumia 1020 noticed Nokia push cell era previous its snapping point. The corporate had a creaking chipset, 2GB of RAM and handiest Qualcomm’s ISP to paintings with. This ended in shot-to-shot occasions of round 4 seconds, as the telephone stored 5MP oversampled photographs and 38MP snaps in a single move.
Five years later, cell silicon has come some distance. The Hisilicon Kirin 970 isn’t relatively as nimble as the Snapdragon 845 and Exynos 9810, owing to its somewhat older cores (it used to be launched a couple of months sooner than Samsung and Qualcomm’s perfect), nevertheless it’s nonetheless masses speedy and packs devoted AI silicon.
Combine the new processor with 6GB of RAM and a devoted symbol sign processor, and considered one of the 1020’s largest problems (deficient shot-to-shot occasions) is a factor of the previous. Unfortunately we don’t have the possibility to save 10MP pixel-binned snaps and 40MP photographs in a single move.
Compared to the 1020’s internals, that have been getting older even again in 2013, the P20’s Kirin 970 can deal with exponentially extra symbol processing. Paired with extra RAM and Huawei’s NPU, the efficiency of the P20 simply presentations how a lot era has complicated in the closing 5 years.
Does it constitute the apex of cell pictures?
The P20 Pro’s digicam specifications on paper on my own make it worthy of popularity, however as our protection presentations, precise picture high quality will also be unbelievable as smartly.
Is it in reality higher than the Lumia 1020, even though? Our shootout solutions that query.
