Comparison of global and rolling shutter

Summary edit

Description
English: Global shutters capture the whole image at once. This takes time, so you might miss frames. Rolling shutters capture one line at the time. This can be fast, but if you are not fast enough the object will move between the acquisition of one line and the next. The video used is from here.
