7.1.2 Global shutter
The shutter is describing the functionality of exposing the light sensitive
pixels of the sensor to light for a limited time. With Global shutterall pixels
are exposed to light at the same time. All pixel will be exposed to light at
the same starting point, and all pixel light exposure will stop at the same
time. Fast moving objects will be captured without showing movement
distortion, except motion blur if the moving object is so fast that the same
point of the object covers different pixels at start and end of the exposure
time in the image.
A global shutter image is a snapshot of the whole scene. Below are
illustrations of some images taken with different shutter types. The camera
does not move, the bottles are sitting on an assemly line driving by.

Using flash with global shutter is simpel: just make sure your flash is on
while shutter is open, thus exposure is running.
