Image stabilisation is a technology used in cameras, lenses, camcorders, and binoculars to reduce the effects of camera shake and produce sharper images, especially when shooting handheld. It works by compensating for small, involuntary movements, helping to maintain image clarity at slower shutter speeds or when using longer focal lengths.
There are different types of image stabilisation, including optical stabilisation within the lens or camera body and digital stabilisation through software processing. By minimising blur caused by movement, image stabilisation is particularly valuable in low-light conditions, telephoto photography, and video recording, allowing photographers and videographers to achieve more consistent, professional results.
