Optical stabilisation plus camera module-say goodbye to shaky blur
Difference between optical and electronic stabilisation:
The principle is different:
Optical stabilisation compensates for jitter through mechanical movement of the lens or image sensor. After the gyroscope in the lens detects the small movement, the signal will be transmitted to the microprocessor to calculate the compensation displacement, and then the compensation lens group or motion sensor will compensate according to the direction of the jitter and the amount of displacement.
Electronic stabilisation relies mainly on the analysis and processing of captured image data to achieve stabilisation. Sensors such as gyroscopes on the camera body are used to detect shake information, and then complex algorithms are used to correct the shake by adjusting the frame position of the image, cropping edges, or interpolating pixels.
Hardware dependency is different:
Optical stabilisation requires special optical components and mechanical structures, such as movable lens groups, suspension lenses, sensors that can move, and corresponding drive motors, which increase the complexity and cost of the device.
Electronic stabilisation does not require additional mechanical components and relies mainly on software algorithms and electronic components such as sensors, processors and related circuits, which are relatively low-cost and easy to implement on small devices.
The effect of anti-shake is different:
Optical stabilisation has no damage to the image quality, and the effect is remarkable, especially in low-light and telephoto scenes, it can effectively reduce the blurring caused by shaking, and generally increase the shutter speed by 2-3 stops, so that the success rate of hand-held shooting and the image quality can be greatly improved.
Electronic stabilisation has a relatively weak anti-shake effect, especially when dealing with large-scale shaking, which may result in distortion, blurring or stretching of the image, and may damage the image quality to a certain extent, and the field of view of the image may be reduced due to cropping.
Different application scenarios:
Optical stabilisation is often used in scenarios with high image quality requirements, such as professional photography, high-end video cameras, main camera and telephoto lenses of smartphones, etc. It is suitable for photo shooting and video shooting in low-light environments, and can significantly improve image quality.
Electronic stabilisation is mainly used in small, low-cost devices and scenes that do not require particularly harsh image quality, such as some low-end cameras, sports cameras, drones, smartphone video shooting, etc., which can reduce video frame-to-frame jitter to a certain extent and make the image smoother and more stable.
Advantages of optical stabilisation over electronic stabilisation:
High image quality: It can provide clearer and more stable images under various shooting conditions, especially in low-light and telephoto shooting, effectively avoiding blurring caused by hand-shaking and better capturing details and colours.
Physical stabilisation is more direct: it solves the problem of shaking from the physical level, adjusting the optical path directly without relying on software algorithms in the later stages, so the stabilisation effect is more natural and realistic, and there will be no image distortion caused by the algorithms.
Strong multi-axis stabilisation: Some advanced optical stabilisation technologies are able to achieve multi-axis stabilisation, covering a wider range of shaking scenarios and providing more comprehensive and precise stabilisation effects, which is suitable for complex shooting environments and sports scenes.
Improve telephoto shooting: When shooting with a telephoto lens, small shakes are magnified, making it difficult to focus on the subject and blurring the image. Optical stabilisation better counteracts the effects of hand tremor in telephoto shooting scenes, allowing the shooter to capture distant objects with greater ease.
Combine with other technologies to achieve better results: Optical stabilisation can be combined with other advanced shooting technologies, such as large bottom sensors, high-megapixel lenses, and multi-camera systems, to further enhance the shooting effect in collaboration with each other.
