Rolling shutter describes the process of image capture in which a still picture (in a still camera) or each frame of a video (in a video camera) is captured not by taking a snapshot of the entire scene at a single instant in time but rather by scanning across the scene rapidly, vertically, horizontally or rotationally. Thus, not all parts of ...
Today, most digital cameras use combination of mechanical shutter and electronic shutter or mechanical shutter solely. Mechanical shutter can accommodate up to 1/16000 seconds (for example the Minolta Dynax/Maxxum/α-9 film camera had a maximum of 1/12000, a record in its era, and the later digital Nikon D1 series were capable of 1/16000 ...

Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().

An electronic shutter can compensate for the exposure change caused by a speed ramp without changing the aperture and affecting depth of field. Other types of shutter adjustments, such as an out-of-phase shutter and a fluttering shutter, are also possible. Normally the film is held steady in the gate whenever it is exposed to light.
This enables it to take still images and videos without any rolling shutter. [3] It also allows it to sync to flashes at any shutter speed, up to its minimum shutter speed of 1/80000 second. This is in contrast to mechanical or electronic rolling shutters that have a longer minimum flash sync speed than the camera's minimum shutter speed.
