Nokia 9 PureView

The modules are factory-calibrated to insure proper alignment, but they are also automatically recalibrated as needed when they are used. By leaving the color filter off of the monochrome modules, they can gather more light and have more resolving power than an equivalent RGB module. In fact, all five camera modules are active for every full-color image, with all three monochrome modules active when capturing in black and white.

That means that for each color image, the Nokia 9 has 60MP of data to work with. By combining up to four tightly-stacked images for demanding scenarios, it can have up to a maximum of MP to work with for a single image. Their secret sauce is not just relying on the camera module array to capture the images, but also on a processing pipeline that creates better quality output. Having five simultaneous captures also creates the possibility of excellent low-light images, even when capturing scenes with motion.

This would be a solid advantage over current Night modes that work well only with very limited subject motion. The version on the left was taken using just one camera by masking the others , while the image on the right was taken with all cameras active. You can see that the image taken using all the cameras has much lower noise.

It looks more like the results of an optical zoom than the image from the single camera image, which looks more like a typical digital zoom.

While shooting in RAW is the traditional gold standard for photographers, in current smartphone models, shooting in RAW typically means foregoing the advanced computational imaging that the manufacturer has painstakingly optimized for that particular phone. There are still plenty of cases in which depth is misestimated. By having five camera modules working at once, the company says that the Nokia 9 is able to record depth at different levels, from near objects at 7 centimeters to those as far away as 40 meters, providing unprecedented accuracy and a large range.

The depth map can also be recorded in an impressive 12MP resolution.

All of that means there is a potential for improved bokeh for portraits, both because it has a real multi-view system with five points of view, and because the separation of the camera modules provides a slightly larger baseline than is common in most phones with two cameras. You can shoot either with the full depth effect enabled, or simply have the phone record a depth map for later processing.

Below are examples of how you can use depth information to change the look of an image after you capture it.

For the middle image, we refocused on the background. For the image on the right, we maximized the depth of field by setting the Blur slider in Google Photos to its minimum value.

Design and display

Refocusing in particular may not get used much, but could definitely come in handy if the camera accidentally focused on something close when you wanted the subject to be something farther away. By using multiple camera modules with the same field of view for each shot, but setting them to varying exposures, the Nokia 9 is able to capture true high- dynamic range HDR images in a single frame , instead of with a burst of frames that most cameras require.

Of course, since the monochrome sensors gather much more light than the color versions, they may have a slightly different exposure anyway. The result of this flexible approach to creating HDR images can be outstanding shadow and highlight detail compared to an image captured when using just a single camera on the Nokia 9.

However, the results are not as impressive as many other current phones that use a quick burst of multiple frames, as you can see in our full review. Below you can see the difference between a single-camera image on the left generated by masking four of the five cameras , and the one taken with all modules active on the right. Having monochrome sensors also means that serious photographers who want to shoot in black and white can capture black and white images natively in-camera. That might be a big win for photographers: for starters, the monochrome sensors capture several times more light than the RGB sensors, giving them a potential advantage in low light.

When viewed at full size, the post-processed image actually shows fewer artifacts than the native monochrome image. Of course, the RGB image also had the advantage of incorporating information from the three monochrome sensors, so they are active in both cases. Aside from the obvious increase in cost, and required space in the phone, there are a number of difficult technical challenges that need to be addressed.

As a starting point, all the modules need to be correctly aligned and calibrated. A rock-solid mechanical design is a great beginning, but the alignment needs to persist in the field and under a variety of environmental conditions. Despite being a cheaper chip, the G actually has some design advantages over the flagship The G is Qualcomm's first chip with an integrated 5G modem, while the offloads 5G and 4G to a separate chip.

The integration of as many components as possible into a single SoC is the technical foundation of the modern smartphone, and usually, this approach uses less space and less power, generates less heat, and is cheaper. Next year, all of Qualcomm's 5G chips will probably be designed like the G, but this year, that chip is leading the way. Don't get me wrong, 5G is not something anyone should really care about at this point, thanks to the nearly non-existent state of the world's 5G networks.

The other kind of 5G, sub-6GHz, has the potential for a wider rollout, but it hasn't been significantly faster than 4G in real life. Further Reading Millimeter-wave 5G will never scale beyond dense urban areas, T-Mobile says 5G is an easy sales pitch, though, so even if consumers won't see much benefit from it, phone manufacturers are charging ahead with 5G.

Qualcomm has made 5G hardware mandatory for every phone with a Snapdragon , even in places with no viable plans to build 5G networks.

Nokia is making some vague claims that this phone has wider 5G compatibility than other devices. As for the other differences between the two chips, the G is a bit slower across the board. Both are eight-core, 7nm SoCs, but the G is split across two Cortex A76 cores and six A55 cores, while the has four newer A77 cores and four A55 cores. Other specs include a 6. There's a microSD slot, a 3. The biggest oddity is a lack of an in-screen fingerprint reader, which has been difficult to integrate into LCD panels in the past.
