Check Out the Differences Between OIS and EIS in Camera Stabilizers

Check Out the Differences Between OIS and EIS in Camera Stabilizers. Some mid-range camera smartphones may not have many of these features. OIS and EIS are rarely found in mid-range smartphones and most flagship or premium smartphones with a myriad of sophisticated camera features.

Cameras on electronic devices, such as smartphones or digital cameras, are often equipped with this stabilization technology to reduce the effects of hand shake that can cause images or videos to become blurry or unsharp. The two main technologies often found in modern devices are OIS (Optical Image Stabilization) and EIS (Electronic Image Stabilization). Although both have the same goal, which is to produce more stable images or videos, they work in very different ways. Here is an in-depth explanation of the differences between OIS and EIS.

1. OIS (Optical Image Stabilization)

Definition OIS is an optical-based image stabilization system that involves the physical movement of the camera lens elements to compensate for hand movement or vibration. In OIS, the camera sensor detects unwanted movement or vibration and sends a signal to move the lens element or sensor to correct the position.

How it Works
Gyroscope Sensor: OIS works with the help of a gyroscope sensor that detects camera movement. When the camera moves or shakes, the sensor sends information to the lens mechanism.

Lens or Sensor Movement: The camera lens or sensor then moves to compensate for the shake or movement, keeping the image stable.

Result: OIS is very effective at reducing blur caused by hand movement when shooting photos or videos, especially in low light conditions or when using zoom.

OIS Advantages
More Effective in Still Photos: OIS is better in still shooting situations, especially in low light conditions, because it can slow down the shutter speed without sacrificing image sharpness.

Zoom Stabilization: OIS provides great benefits when using optical zoom or when shooting moving objects at a distance.

OIS Disadvantages
Requires Space: OIS systems require more complex and expensive mechanical components, which can make the device larger and heavier.

Limited to Small Movements: OIS is effective in small movements and is not so optimal for stabilizing larger or fast movements.

2. EIS (Electronic Image Stabilization)
Definition EIS is a software-based image stabilization system that utilizes image processing to reduce shaking or shaking. EIS works by cropping a small portion of the image captured by the sensor and then processing it to adjust for movement or vibration.

How it Works
Digital Processing: EIS uses software algorithms to detect camera movement through frame-by-frame processing.

Crop & Compensation: When movement is detected, EIS will crop a small portion of the image area and adjust its position to correct the imbalance caused by shaking.

Results: EIS is more effective in video because it can reduce the effects of shaking without requiring additional hardware.

Advantages of EIS
No Physical Components Required: Because it is software-based, EIS does not require mechanical components like OIS, which makes it cheaper and lighter.

Effective for Video: EIS is more useful in video recording, especially when recording with fast movement or in conditions that require video stabilization.

Disadvantages of EIS
Reduced Image Resolution: Since EIS crops part of the image to compensate for shaking, the resolution and image quality can be reduced, especially at high resolutions.

Less Effective in Still Photos: While EIS works well for videos, the quality of still photos can be less than optimal due to the cropping of parts of the original image.

3. Using a Combination of OIS and EIS
In some modern devices, especially smartphones, OIS and EIS technologies are often used together to achieve optimal stabilization. In this case, OIS is used to compensate for small shakes, while EIS handles larger movements or changes in the camera's viewing angle. The combination of these two technologies allows the device to produce very stable images and videos, even in very dynamic conditions.

Here is a comparison of OIS (Optical Image Stabilization) and EIS (Electronic Image Stabilization) in a more structured form:

1. How it Works
OIS (Optical Image Stabilization)

OIS works physically. When the camera moves or shakes, the lens element or sensor moves to compensate for the movement, keeping the image stable. This movement is detected by the gyroscope sensor and corrected by a mechanical mechanism in the lens or sensor.

 

EIS (Electronic Image Stabilization)

EIS uses software to analyze and correct camera movement. In this way, EIS crops a portion of the captured image and shifts or modifies it digitally to reduce the effects of vibration or shake.

2. Components Used

OIS
Requires mechanical components, such as lenses or sensors that can move. This system is more complex and takes up more space in the device.

EIS
Does not require mechanical components. It only requires software processing, which makes it cheaper and lighter.

3. Effectiveness in Still Photos

OIS
Very effective in still photos, especially in low light conditions or when using slow shutter speeds. OIS maintains image quality because there is no cropping or resolution changes.

EIS
Less effective for still photos. Because it is software-based, EIS can crop parts of the image, which reduces the resolution and image quality.

4. Effectiveness in Video
OIS
Quite effective for video, especially with small movements or zooms. However, with larger or faster camera movements, OIS tends to be less effective.

EIS
More effective for video, especially when there is fast movement or large shaking. EIS can correct for camera movement well, although image quality can be slightly reduced due to image cropping.

5. Image Quality
OIS
Preserves image quality better because there is no cropping of the original image. Therefore, OIS is more ideal for high-resolution photos and high-quality videos.

EIS
Can reduce image quality because it uses a cropping technique that reduces the visible area of ​​the image. This can affect image resolution, especially when recording in high quality.

6. Cost & Complexity
OIS
More expensive and more complicated because it involves physical mechanisms and moving components. It also makes the devices that use it larger and heavier.

EIS
Cheaper and simpler because it is software-based. EIS does not require mechanical components, making it lighter and more cost-effective.

7. Combined Use of OIS and EIS
Some modern devices, such as smartphones, combine both technologies. OIS is used to overcome small shakes in photos and videos, while EIS is used for more dynamic video stabilization, especially in fast movements. The combination of the two provides optimal stabilization in various conditions.

OIS is better for still photos and low-light conditions, and provides higher image quality without sacrificing resolution. EIS is more effective for video and stabilization in large or fast movements, although it can reduce image quality due to cropping. Both have their own advantages and are often used together for the best stabilization results.

Conclusion
OIS is more ideal for still photo use, especially in low light conditions or when using zoom, because it provides more effective optical stabilization without sacrificing image quality. Meanwhile, EIS is more suitable for video recording, especially when the camera movement is larger and in conditions that require digital correction.

However, both OIS and EIS have important roles in improving the quality of the results of shots and video recordings, and choosing between the two depends on the type of use you need. In many cases, using both together can provide very good results. So to get this feature, a high budget is needed to have it, because there is a price for goods that are obtained.
