Electronic image stabilization (EIS) is an improved technology in mobile imaging. Not many OEMs are using it over optical image stabilization (OIS) but there are those like Google who has already tried to include the feature in the previous Nexus 5X but it must be enabled. The Nexus 6P already has it by default. Other Android devices have it too like the LG V20 and LG V10. Action cameras like the Xiaomi Yi 4K action camera and GoPro HERO5 also boast of EIS.
The new Google Pixel and Pixel XL have this feature but people are asking why the company chose the electronic image stabilization(EIS) over optical image stabilization (OIS). Is it any better? Several questions were raised at the Pixel User Community Google forum and two responses from one person can be considered the ‘best answers’.
A certain IsaacOnCamera explained that you really cannot compare the two because they have different goals. EIS is more for video while OIS is for photos. The latter also enhances low light photography, compensating for the hand shake. Its goal is to allow longer exposures in low light. Its size makes it a challenge to include in a Pixel while EIS is smaller, therefore, the best choice for the Google-branded smartphone.
The OIS module allows a smartphone to perform even in low-light conditions and it actually works well with HDR+ and other software algorithms of the Pixel according to IsaacOnCamera. He further added that EIS on 4K is now supported on the Pixel. The Nexus 6P has the same EIS feature but it doesn’t support 4K yet so this is an improvement.
