Various methods, apparatuses, and systems in which a digital photography
device includes a global shutter to control exposure time, a sensor
array, and a flash illumination are described. The global shutter is in
the optical path of light going to the sensor. The flash illumination
generates a pulsed illumination. The shutter speed of the global shutter
during a pre-flash illumination substantially matches the shutter speed
during the flash illumination during the taking of a picture using the
flash illumination based on the global shutter receiving a trigger signal
from a controller.
