Abstract
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.
