Exposure time length is different in each line
As
no difference in exposure starting time in lines
shutter, exposure starting time can be measured easily as
global shutter.
However, as
exposure ending time is different
image of moving subject under constant light is distortive due
to luminance difference.
As a result, low cost advantage will be offset by additional cost
of strobe. There is a certain advantage of easier measurement
in exposure starting time comparing with rolling shutter.
