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.

Resetting and
starting exposure
in all the lines at
the same time
Starting time of exposure is same in each line. However, exposure
time length are longer in lower line. Hence distortion and
luminance difference in image is caused under constant light.

As no difference in exposure starting time in lines like rolling
shutter, exposure starting time can be measured easily as
global shutter.
However, as
exposure ending time is different in each line,
image of moving subject under constant light is distortive due
to luminance difference.
