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 ...
Extremely fast shutter operation is possible as there are no moving parts or any serialized data transfers. 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 ...
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 ().

A roller shutter and window combined as a single unit. Roller shutter with tilting louvres A roller shutter with laths that tilt, similar to an external venetian blind. Manual With gear drive from the shutter roller traced through the building facade to a universal joint on the room side that is operated by a cranked winding handle. Manual tape
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.
The iPhone 11 includes a dual-lens 12 MP rear camera array. It has one ƒ/2.4 ultra-wide-angle lens with a 120° field of view and 2× optical zoom out, and one ƒ/1.8 wide-angle lens. The iPhone 11 supports 4K video at up to 60 fps and 1080p slow motion at up to 240 fps. [2]
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
On a sunny day at ISO 100 ("100 speed film"), the aperture is set to f /16 and the shutter speed (i.e. exposure time) to 1 / 100 or 1 / 125 [2] seconds (on some cameras 1 / 125 second is the closest available setting to 1 / 100 second). On a sunny day at ISO 200 and aperture at f /16, set shutter speed to 1 / ...
