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 ...
English: An example of the Rolling shutter effect in action at Afton Down, Isle of Wight.This photograph was taken from a car travelling at approximately 50 miles per hour, and the rolling shutter effect has resulted in the fence and gate appearing slanted while more distant objects, such as the two walkers behind the fence and Afton Down in the distance appear normal.
Global shutter can also be used for videos as a replacement for rotary disc shutters. Image sensors without a shaded full-frame double must use serialized data transfer of illuminated pixels called rolling shutter. A rolling shutter scans the image in a line-by-line fashion, so that different lines are exposed at different instants, as in a ...
Effect of a rolling shutter on a spinning disc: Image title: The effect of a rolling shutter on a spinning disc simulated by CMG Lee. The jagged appearance is due to the small number of rows; the higher number of rows in a real camera results in smoother curves. Width: 1600: Height: 1200
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.

Zoom burst, a photograph taken with a zoom lens, whose focal length was varied during the course of the exposure. In a sense, ICM is the same effect as (intentional) single-exposition motion blur: in the former the camera moves during exposure, in the second the target moves, but they have in common that there is relative motion between camera and target, often resulting in streaking in the image.
