Hover Camera Test: How’s the EIS work

When we talk about drone camera gimbals, there are a number of different classifications possible. Here, we will look into some of these different types.

Drones usually are available in 2-axis and 3-axis brushless gimbals for the camera. Each of these types has its own set of pros and cons. The one you opt for between the two, depends on the purpose of utilization.

But with the drone getting smaller and smaller, how to make 3-axis gimbal as small as the aircraft becomes the most important issue. So they come out a solution to use 1-axis gimbal combined with EIS, the Electronic Image Stabilization, this technique shifts the electronic image from frame to frame of video, enough to counteract the motion. It uses pixels outside the border of the visible frame to provide a buffer for the motion. This technique reduces distracting vibrations from videos by smoothing the transition from one frame to another. This technique does not affect the noise level of the image, except in the extreme borders when the image is extrapolated. It cannot do anything about existing motion blur, which may result in an image seemingly losing focus as motion is compensated.

The pitch axis can remove some shakes from aircraft, but EIS covers the most job. What the EIS do is so limited. So we can see, when in strong wind, the video quality of Hover Camera is shaky. Before you can see the detailed Hover Camera Test from Tested in Youtube:
