In the world of photography and surveillance, image stabilization is an important feature that helps to capture clear and stable images. There are two main types of image stabilization technologies used in cameras today – lens-based and sensor-based OIS (Optical Image Stabilization).
Lens-based OIS technology is commonly found in DSLR and mirrorless cameras. This technology works by using a floating lens element that moves in response to camera shake, thereby compensating for any movement and keeping the image stable. Lens-based OIS is highly effective in reducing blur caused by camera shake, especially when shooting in low light conditions or with a long zoom lens.
On the other hand, sensor-based OIS technology is commonly found in compact cameras and some smartphones. This technology works by using a gyroscope sensor to detect camera shake and then shifting the sensor in the opposite direction to compensate for the movement. Sensor-based OIS is highly effective in reducing blur caused by camera shake, especially when shooting handheld or in motion.
When it comes to CCTV cameras and surveillance systems, both lens-based and sensor-based OIS technologies are used. However, lens-based OIS is more commonly used in CCTV cameras as it is more effective in reducing blur caused by camera shake and provides better image stabilization for long-range surveillance.
In conclusion, both lens-based and sensor-based OIS technologies have their own strengths and weaknesses. Lens-based OIS is more effective in reducing blur caused by camera shake, especially in low light conditions or with a long zoom lens, while sensor-based OIS is more effective in reducing blur caused by handheld or motion shooting. The choice of OIS technology depends on the camera type and its intended use, whether it is for photography, surveillance or other applications.
