Images and video that suffer from rolling shutter distortion can be improved by algorithms that do rolling shutter rectification, or rolling shutter compensation. How to do this is an active area of research. [5] This effect can be used to gain secret keys from certain smart card readers. [6] [7]
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.
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.
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 "Silent Shutter" mode is available, which does not cause the mechanical shutter to operate and thus avoids making any shutter sound. [6] However, this uses an electronic shutter mode which works by reading the sensor one line at a time, and this means that fast movement during the read will cause a rolling shutter effect, leading to an image ...
