BACKGROUND
The Nokia 808 PureView camera phone, launched in
2012, included world-leading advances in image quali-
ty in terms of resolution, sharpness and clarity. Innova-
tive oversampling technology provided a level of image
detail previously unseen in mobile, or even small scale,
digital imaging systems. In addition, pixel oversampling
combined many pixels to create a single super-pixel.
This allowed us to keep virtually all the detail but to lter
visual noise away from the image. Images looked more
natural and were purer, giving a more accurate repre-
sentation of the original subject than had ever been
achieved before.
Nokia 808 PureView was pioneering and provided
benchmark image quality. We received extremely pos-
itive feedback but users kept challenging us for even
better low light imaging capabilities, especially without
ash. This feedback inuenced the development of our
second generation PureView phone – the Nokia Lumia
920 PureView.
The Nokia Lumia 920 was the rst global smartphone
to implement optical image stabilization (OIS) to set a
benchmark in low light image quality. We implemented
a back-side-illuminated (BSI) sensor with f2.0 aperture,
optical image stabilisation and the most sensitive pixels
seen in a camera. All this was built on top of the Win-
dows Phone 8 platform for seamless social media shar-
ing, and equipped with Nokia’s own state-of-the-art
imaging algorithms. This allowed the Nokia Lumia 920
– and the more recently announced Lumia 925 and 928
– to revolutionise low light imaging.
In 2013 we had two kinds of camera phone in our Pure-
View range, providing imaging capabilities previously
unseen in mobile, each one leading dierent areas of
digital imaging. One provided benchmark performance
in capturing details, and another set records in low light
imaging. The natural next step was to take those two
award-winning PureView innovations as the starting
point to create the ultimate next generation imaging
smartphone. Let us introduce the Nokia Lumia 1020.
BEST OF BOTH WORLDS:
SHARPNESS AND LOW LIGHT
The second generation 41 megapixel sensor uses the
latest generation 1.1 micron back-side-illuminated (BSI)
pixels, providing excellent noise performance as well
as benchmark resolution. The sensor format is 1/1.5”
and it is up to ve times larger than typical smartphone
sensors. The redesigned sensor provides all the imag-
ing innovations introduced with Nokia 808 PureView
– meaning high resolution zooming and pixel oversam-
pling – plus new innovations in a revised, more modern
camera module.
The Nokia Lumia 1020 introduces the second gener-
ation of our optical image stabilization (OIS) system
rst found in the Lumia 920 PureView, to provide a new
benchmark in image stabilisation systems. We include
the most sophisticated xenon ash and video-light LED
implemented on any Nokia phone to help users freeze
the moment.
One of the critical design decisions in a camera is bal-
ancing the subjective image sharpness and noise per-
formance. Image sharpness and low light performance
(noise or grain) are two sides of the same coin in camera
