wlaidlaw Posted September 10, 2021 Share #2  Posted September 10, 2021 A video camera maker could always mount three of these sensors behind a beam splitter and filters like a digital version of the 3 strip/color Technicolor system, used in movies from the 1930's onwards. Size of the camera is less important for the professional video market than output quality. I think all the current 8 and 12K sensors (Red, Blackmagic, etc) are rolling shutter. Wilson 1 Quote Link to post Share on other sites More sharing options...

BernardC Posted September 10, 2021 Share #4  Posted September 10, 2021 8 hours ago, Pelu2010 said: Since it is 5 years of this announcement.... That announcement is for a monochrome industrial sensor. The sensor itself was probably made for very specific requirements where a global sensor is required, like measurements of items in motion on a production line (where you don't want sensor-induced distortion). As Wilson mentioned, even cinema cameras don't have global shutters, except for a few special cases. Arri Alexa cameras have rolling shutter, and they've been used in most blockbusters and Oscar winners for the past decade. It's not a big concern, as long as the sensor readout time is reasonably quick. Quote Link to post Share on other sites More sharing options...
wlaidlaw Posted September 10, 2021 Share #5  Posted September 10, 2021 Aircraft propellors are the biggest problem with rolling shutters. However I take the point that repurposing industrial sensors for cameras has not had a very happy history. Think back to the disastrous Contax ND, which used a Philips/Dalsa full frame sensor. The camera was pretty much unusable at anything over its base ISO of 50 because the sensor had never been designed to allow for signal amplification, so no correction look-up tables had been written. Wilson Quote Link to post Share on other sites More sharing options...
beewee Posted September 11, 2021 Share #6  Posted September 11, 2021 Global shutters have been around for a while but there are tradeoffs in that the extra circuitry needed on the sensor takes up space, uses more power, and generates more heat. So the end result is a combination of increase noise, decrease in dynamic range, and reduced sensor sensitivity, at least compared to a similar sensor without global shutter. The benefit of global shutter would be no rolling shutter when using electronic shutter, and the potential to do away completely with the physical shutter. This would make space for IBIS in smaller cameras like the M cameras which do not have IBIS because there’s not enough space for it. 1 Quote Link to post Share on other sites More sharing options...
