Định Nghĩa và Ý Nghĩa của "image stabilization"

What is "image stabilization"?

Image stabilization (IS) is a technology used in cameras and lenses to reduce blurriness caused by camera movement or shake, especially in low-light conditions or when using a zoom lens. It works by counteracting small, unintended movements of the camera during the capture of an image or video. This can be done by either shifting parts of the lens or camera body to compensate for small movements, or by digitally correcting image distortions. Image stabilization helps produce clearer, sharper images, even when the camera is handheld or the subject is moving.
