Rolling shutter is a more than extreme baloney of the image acquired by the shutter of certain cameras that can make subjects announced to change shape while in motility.

Some cameras, such as those with CMOS sensors do not capture the entire frame of their epitome in a single instant. Instead, they make use of what is known as a rolling shutter, where the image is captured progressively every bit the shutter rolls over the sensor.
