Nokia Lumia 920 beats Samsung Galaxy S4 in video stabilisation test

nokia-lumia-920-samsung-galaxy-s4We know the Nokia Lumia 920 is the most versatile and compelling smartphone out there but it’s not every day you get the chance to compare it to the new Samsung Galaxy S4. This hands-on video of them both recording video on the go shows why the Nokia Lumia 920 running Windows Phone 8 clearly has the edge.

We’ve seen the Nokia Lumia 920 set up to compete against similar smartphones before, testing the video quality and the Optical Image Stabilisation (OIS) of the two smartphones. WP7Forum.ru has posted a video of the Nokia Lumia 920 going up against the Samsung Galaxy S4 in the Optical Image Stabilisation stakes.

OIS works by detecting camera movement using a highly accurate sensor to detect the degree and direction of movement. But that’s pretty much where the similarity between Nokia’s OIS system and broadly comparable OIS systems ends.

The video is in Russian but it’s easy to understand what is going on. Both smartphones are strapped to the top of a toy car and then both record the journey as they’re pulled along the floor. The footage at the end of the video shows how effective the Nokia Lumia 920 is delivering infinitely better footage than the Samsung Galaxy S4.

If you’re wondering why the Nokia Lumia 920 offers such an immediately noticeable better quality image than on the Samsung Galaxy S4 it’s all to do with how the OIS unit itself is built. We’ll refer you to the Nokia White Paper for the science:

‘In most OIS systems, a lens element moves in the opposite direction to the measured device movement to compensate for unintended movement, effectively cancelling out camera shake. Nokia’s OIS system moves the entire optical assembly in perfect synchronisation with the camera movement, or to be more precise, unintended camera shake. The benefit is that the amount of camera movement that can be compensated for is much greater. Many OIS systems may only be able to handle movement frequencies up to a certain level. Based on Nokia lab tests, Nokia’s OIS system can cater for around 50 per cent more movements per second than conventional OIS systems up to around 500 movements every second.

Besides the high frequency compensation, the system also needs to be able to respond extremely quickly to unintended movement to avoid so called “phase shift” or compensation lag. To help achieve this very fast reaction time, Nokia uses a closed loop system where the position of the lens assembly is monitored in real time, even whilst it’s moving to its calculated position allowing it to be continuously updated regardless of how random the camera movement is. This process of checking operates at a rate of up to 5x more frequently than typical OIS systems, approximately 300 times faster than that of the average human reaction time to an expected event.’
