Shutter mode comparison 1

RS: Rolling shutter

GS: Global shutter

Same exposure start time

in each line. Hence no distortion

of moving subject image under constant light.

Exposure start time is different in each line. Hence

“distortion” of moving subject image

is caused under

constant light.
