Super Resolution with Nokia Lumia 1520. How pure can a Pureview be?

As Nokia made RAW format available in Lumia 1520, we took a chance to test Almalence Super Resolution technology with it.

As Lumia 1520 always outputs 5 Megapixel image, the comparison has been made between:

  • Standard image at maximal zoom (pixel-to-pixel crop from the sensor with no resampling) bicubically upsized 2x, and
  • 5 Megapixel crop from 19 Megapixel RAW, zoomed 4x with Almalence Super Resolution Zoom

Results in brief

  • Noticeable increase of effective resolution
  • Simultaneous noise reduction
  • Processing time for 5Mpix output at 4x on MSM8974 at 2.3GHz (Lumia 1520 chip set): 0.38 sec

Conclusion

Nokia’s approach to improving the quality of zoomed images is using higher-resolution sensors. The results of Super Resolution testing clearly show that Almalence’s Super Resolution Zoom is not just an alternative, but a great addition to that approach, providing not only higher resolution and allowing higher zoom levels, but also drastically reducing the noise.
