Rolling Shutter

A rolling shutter is a type of image capture in cameras that records the frame line by line on an image sensor instead of capturing the entire frame all at once. The rolling shutter sensor scans from the top of the image to the bottom, so the top of the frame is recorded slightly earlier than the bottom.Rolling shutter is a type of image distortion that occurs when the motion of a subject is moving too fast for the camera's sensor to capture properly. The effect can also occur if the subject is static but the camera is in rapid motion.
