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]
The shutter behavior of the camera influences aliasing, as the overall shape of the exposure over time determines the band-limiting of the system before sampling, an important factor in aliasing. A temporal anti-aliasing filter can be applied to a camera to achieve better band-limiting and reduce the wagon-wheel effect.
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
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.
The stroboscopic effect visibility meter can be applied for different purposes (see IEC TR 63158 [12]): Measurement of the intrinsic stroboscopic-effect performance of lighting equipment when supplied with a stable mains voltage; Testing the effect of light regulation of lighting equipment or the effect of an external dimmer (dimmer compatibility).
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 ...

Compared to its predecessors, the RX100 IV also has a faster electronic shutter and increased read-out speed for video, which will also result in a reduction in rolling shutter effect and allow high speed video to be captured.
