Nokia 9 PureView camera system

The Nokia 9 powered by the Qualcomm Snapdragon 845 Mobile Platform is a major achievement in computational photography. Thanks to a collaboration with HMD, Light, and Qualcomm Technologies, the Nokia 9 is the world’s first smartphone to feature a five-camera array. Every time you take a photo, the cameras collectively capture and process up to 240 megapixels of data, which is then used to create one stunning 12-megapixel photo and a corresponding 12-megapxiel depth map. This is the largest amount of photography data ever captured and processed by a Snapdragon 845 device. By combining the best parts of the data to form one image, the Nokia 9 is designed to ensure your photos feature stunning sharpness, bright colors, dynamic range(12.4 stops), and depth for realistic-looking Bokeh.



The five-camera modules that make this possible are nearly the same. They contain the same Sony IMX486 image sensors, which have 1.2μm size pixels, and lenses, which have 28mm focal length with bright f/1.8 apertures. The only difference among the cameras is that two of the image sensors can collect color via the color filter, while the other three cameras use the same sensors without color filters.

These are typically called “monochrome” image sensors and are capable of capturing 3X more light. So each camera captures the same image, but at varying exposures(bracketing) so you can shoot both very bright and dark imagery.

Depending on the lighting conditions, the cameras are triggered up to four times in quick succession.

The device then selects one of the colour shots to act as the primary image, and adds detail taken from the other stills.

Overall, the Nokia 9 captures 10X more light compared to a smartphone camera with a single image sensor.




Capturing, sorting, and combining all this data to create one stunning photo takes a lot of processing power. The heterogeneous architecture of the Snapdragon 845 makes it possible to distribute the workload across the platform to the cores that can most quickly and efficiently accomplish the tasks. Some tasks are better suited for the ISP, while others are better suited for DSP, GPU, or CPU. Handling the tasks in this way makes the camera experience feel fast while also conserving battery, so you can capture more photos per charge and maintain efficient battery life.

For example, the Qualcomm Hexagon DSP(from Light's R&D) has smaller pipelines than the Qualcomm Kryo CPU, but it has a lot more of them, making it excellent for processing pixel data in parallel. For this reason, Light’s noise reduction algorithms were moved from the CPU to DSP and as a result, according to Light, it was able to offer more shots per charge as well as process 3X faster and at 10X lower power.

Simultaneously, while noise reduction is being performed, the Qualcomm Adreno GPU is inspecting the 240 megapixels of data to render a 12-megapixel depth map. Most smartphones create a depth map that is a megapixel or less containing three to seven focal planes, but the Adreno GPU creates a massive 12-megapixel depth map filled with up to 1,200 focal planes. This level of depth enables photos with extremely realistic looking Bokeh and massive control over the blur-intensity of the Bokeh in the background and foreground. It also provides an astounding number of regions to shift focus to, so you can shoot now and focus later. The depth maps are created as “GDepth” files – Google’s official file format for depth maps, which can be used and stored in Google Photos.

With its five cameras and the heterogeneous architecture of the Snapdragon 845 that allows them to work together virtually seamlessly, the Nokia 9 makes taking stunning photos easier than ever. And with the tools in hand to take the ultimate shot, you can connect and communicate with the world around you in brand new ways.

The software update with build number V4.27C brings a new live bokeh mode to the Nokia 9. This enables users to adjust the focus point and blur strength on the preview image before capture, as well as in post-processing on the device. The update also increases the speed of image processing which means images can now be captured in faster succession.


Pros:
all HDR, all the time
1200 layers of depth (focal planes)
RAW DNG file output
native black and white photography
more data and smart processing in the phone
Adobe LightRoom integration
excellent 5.99 inch 2k QHD+ (2880 x 1440) pOLED display, 430 nits
ZEISS optics

Cons:
no optical zoom
no OIS (optical image stabilization)
slow
