Global Shutter Coming on Canon 1-series DSLRs(CW2)# PhotoGear - 摄影器材

"A rumor (thanks) suggesting that the next big thing coming from Canon will
be global shutter on all future 1-series DSLRs. The aim is to push the frame
rate of these DSLR to new levels. The EOS-1D X is rumored to get replaced
during 2015. Could be the first Canon DSLR to sport a global shutter.
Most CMOS sensors (as you find on a DSLR) have a rolling shutter, which
reads pixel values from top left to bottom right (typically). The problem
with a rolling shutter is the distortion hat becomes visible with fast
moving, rotating objects. CCD sensors store each pixel value until all
pixels values are read out at once (hence the global shutter).
I do not think Canon will start to use CCD sensors, so the question is how
Canon is going to implement a global shutter on a CMOS sensor. A possible
solution could be to have a memory for each pixel where to store the charge
(value) until all pixel values are read at once. This would keep the
advantages of the CMOS sensor and allow to feature a global shutter. Could
such a technology give higher frame rates?
Please not that this rumor is rated CW2. What do you think about this rumor?"
