3.4 DIS (Digital image stabilization)
Digital image stabilization (DIS) 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.
