Flying a kite, you may have felt the turbulence and vibrations it faces while in the air. So you would imagine that if your kite can survive struggles in the wind, how is it that you can capture your footage. You might have wondered what makes the footage from a camera drone stable despite the wind? It is something called Electronic Image Stabilisation (EIS). EIS is one of the most critical components of the drone and the feature that helps the drone to capture a stable image. Continue reading further to learn more about Electronic Image Stabilisation (EIS)
What is Electronic Image Stabilisation (EIS)?
Electronic Image Stabilisation (EIS) is an image enhancement technique that effectively adjusts and balances the captured image. The system includes a sensor integrated into the camera, reducing jittering and capturing the best stable photos. For example, if the drone shakes left, the camera will shift the focus to the right to match the shifting. EIS incorporates two techniques to make the image stable. First, it either digitally zooms in to capture a more prominent image, which helps scan the pictures to take out the effects of shake. Or, it incorporates a larger sensor to resize the image to fit the available space.
Effectiveness of EIS in Drones
Drones fly in the air, making them susceptible to considerable shaking due to the wind. Without EIS, the drone's camera will not adjust to shaking. For better understanding, pick up an old mobile phone with a camera, and make a video while walking. You'll see a considerable disturbance in the video due to the absence of a stabiliser.
With the rapid increase of drones in different industries, image quality is now more critical than ever. Every content creator requires a drone to film stable aerial footage without compromising quality. EIS is the answer to their plea since the technique reduces the shakiness and vibration, providing the drone users with their desired quality footage. Best drones for photography like Holy Stone HS720E include EIS. The video footage from these drones is better in quality compared with drones that don't have EIS.
Electronic Image Stabilisation Vs. Gimbal Stabiliser:
Drones have been incorporating image stabilisers even before the introduction of EIS. Since drone shaking was a significant issue that resulted in the poor quality image, solutions like Gimbal Stabiliser were introduced. The gimbal stabiliser is different to Electronic Image Stabilisation. EIS stabilises images digitally while Gimbal Stabiliser implements an optical image stabilisation technique to get a stable picture. EIS keeps improving the appearance through equal shifting, whereas the gimbal stabiliser works only after the drone has shifted.
Gimbal Stabilisers are available in two variations: two-axis and three-axis. Drones not equipped with EIS usually have a two- or three-axis Gimbal Stabiliser. The three-axis gives better stability which helps the content creator get their best shot.
Although most camera drones have some form of EIS, not all of them have the feature. With the introduction of this feature in the best beginner drone, the new users will be able to record high-quality footage without hassle. Look out for EIS or Gimbal Stabiliser in the best drones for sale to get the best out of your drone photography. An example of a drone with EIS is the Holy Stone HS720E.
Electronic Image Stabilisation (EIS) reduces the shakiness you experience when capturing your footage. Although the SG906 MAX 1 does not come with EIS, it comes with a three-axis gimbal stabiliser. EIS and gimbal stabilisers attempt to achieve the same result but are different. The gimbal stabiliser absorbs shock from the drone's movement and helps keep the camera levelled throughout the flight.
