Image Stabilization

Image stabilization (IS) is a family of techniques used to reduce blurring associated with the motion of a camera during exposure. Specifically, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of a camera or other imaging device. It is used in image-stabilized binoculars, still and video cameras, and astronomical telescopes. With still cameras, camera shake is particularly problematic at slow shutter speeds or with long focal length (telephoto) lenses. With video cameras, camera shake causes visible frame-to-frame jitter in the recorded video. In astronomy, the problem of lens-shake is added to by variations in the atmosphere over time, which cause the apparent positions of objects to change.

Famous quotes containing the word image:

    If the study of his images
    Is the study of man, this image of Saturday,
    This Italian symbol, this Southern landscape, is like
    A waking, as in images we awake,
    Within the very object that we seek,
    Participants of its being.
    Wallace Stevens (1879–1955)
