& Comparison with Other Smartphones
As we know, Nokia Lumia 920 is a
smartphone which developed by
Nokia, and running the new
system Windows Phone 8. It's now
available.
Comparison with Lumia 900
Compare with the flagship Lumia 900 from Windows Phone 7 era, the two
devices look quite similar, but the case of Lumia 900 is gloomy while 920 is
shiny and smooth, and 920 has a curved screen, which makes it feel better,
more ergonomic.
Lumia 900's resolution is 800 x 480, 1.4GHz single-core processor, and the
RAM is 512 M. Now improvements have been made. Lumia 920 has
equipped with 1.5GHz dual-core Snapdragon S4 processor, 1GB of RAM,
32GB of storage, a 4.5-inch 1280×720 display (326 PPI!); 8.7 megapixels Carl
Zeiss camera, and support pureview shooting technology, wireless
charging, and glove-friendly touchscreen.
PureMotion HD+ Screen
Nokia Lumia 920 has a revolutionary technology - PureMotion HD+. The
PureMotion HD+ uses advanced PureMotion technology to get high pixel
density, brighter screen, and faster refresh. It also makes revolutionary
innovation in the touch-sensitive.

2. HD+ high pixel density
HD+ is about its resolution: 1280 × 768. The number of pixels of its 4.5-inch
large screen is 60% higher thaniPhone 5 (1136 × 640), 7% higher
than Samsung Galaxy S III (720 × 1280).
And the display is more delicate than many competitors' products, the pixel

Super
Sensitive
Touch
Compare with
Other
capacitive
screen mobile
phones that
need to
operate with the pulp, Lumia 920 screen sensibility is beyond al other smart
phones' screens. Users could wear gloves, long fingernails, or even an
ordinary ballpoint pen to complete the phone touch operation.
PureView imaging technology
Lumia 920 is equipped with an 8.7-megapixelrear camera, and the
PureView technology is the first time being used on the Lumia phones.
PureView technology uses advanced optical image stabilization technology.
In a low light environment, and even the flash lamp is not opened, it is still
able to intake five times more light than ordinary mobile phone's camera,
hence no matter users are indoor, or at night, it is capable to capture clear,
bright pictures and videos.
To enhance effects from dark, Lumia 920 adopted a new method – Backside
illumination. The back-illumination (BSI) and a conventional front-
illumination (FSI) have a texture difference between the photosensitive
effects. Thus, although the size of the pixels is the same, but its pixel
photosensitive effect is better.

3. Lumia 920 also uses a Carl Zeiss lens, f/2.0 aperture to capture more lights
into sensor. These changes mean that you can shoot better photos on a
cloudy day, evening or indoor.
More great progress is the optical image stabilization system (OIS), also
known as optical image stabilization. There has some phone supports
digital image stabilization feature, but this cannot be compared with the
OIS. Lumia 920 will be judged by the built-in gyroscope phone direction of
movement, and to move the entire shooting module to ensure that the
hand jitter does not affect shooting. In addition to be able to help bring
excellent video, OIS can significantly enhance the photographic effect in the
dark light, because the longer the exposure time, the more stable needed.
Here is an image that stands for itself:

4. City Lens
Besides PureMotion and PureView, Lumia 920 is also equipped with Nokia's
urban kaleidoscope – Nokia City Lens, which is adding a new suite of Nokia
Map and location-based services augmented to reality experience: only
need to align the camera to the city streets, then the buildings will be
displayed with restaurants, hotels, and other information. It also allows
switching between map view and augmented reality view, to help people
identify the direction and understand the surrounding environment.
