Global and Synchronous Shutter Cameras

The difference between the Global and Synchronous shutter cameras


The difference between the Global and Synchronous shutter cameras => Please see the attached application note from Kodak that describes shuttering types.

Our Global Shutter camera uses the Fill Factory IBIS-5a sensor.Our Synchronous Shutter camera uses the Micron sensors.

Basically, the global shutter is like a photographic camera with a mechanical shutter – It starts exposing all pixels at the same time and stops exposing all pixels at the same time.

The synchronous shutter starts exposing the first row then the second and then rolls downward toward the last row. The pixels stop exposing in the same manner – that is the first row will stop exposing and be read out then the second row will stop exposing and then be read out – likewise downward to the last row. However, the Synchronous shutter camera can be used similar to the Global shutter by getting all pixels to expose at same time (triggering) but keeping them in the dark, then when they are all exposing at the same time – you strobe the illumination ON and then the light is captured by all pixels starting at the same time = then you strobe the illumination OFF so that all pixels Stop exposing at the same time => THEN the scene goes dark and then the first row stops exposing (albeit in the dark) and the camera Rolls through the other rows stopping each rows exposure and reading out the data for each row.
