(K3) New Samsung sensor with global shutter?
We just received very interesting details about a possible future Samsung sensor!
The concept is easy and very interesting to solve the slow speed transfer with global shutter and high resolution sensors.
“Two CMOS sensor on the same chip. This concept apply to 12.4MPx APS-C CMOS sensor.
The sensor integrates noise reduction circuits and 4 “Digital Channels”, two for each half-sensor.
Each half-sensor has 6.2MPx with a speed transfer of 8.2fps through Global Shutter, whole sensor has 12.4MPx with a total transfer rate of 8.2fps.
Both half-sensor are activate and synchronized by “Synchro-shutter” device to the same exactly time and the information from both half-sensor is drained through 4 digital channels to the image processor.
This allow:
-electronic shutter (global shutter mode)
-non-mechanical shutter
-high frame per second
-less static interference (digital channels and just 2 per half-sensor)

This is a new sensor design and control.
Here is how it work.

It has a rolling shutter with controlled activation, every pixels line is delayed the enough time to activate all lines to the same time, “sT 0″, it is the last pixels line activated in the rolling shutter mode.
Uff.. is that true!!!?? I want one of them cameras…
It is a race of global shutter. Let’s see who will become the first to launch a real product. Panny or Sammy？ XD
[...] Via k-rumors [...]
[...] shutter is one of the most requested features of MicroFourThirds user. K-rumors has got some evidence that Samsung is developing such a sensor. Anyway there is not only Samsung [...]
Sony is also developing sensor with global shutter
Presenting at ISSCC, Sony’s Suzuki sees the following trends in digital CMOS sensors:
•Ultra high speed
•Global shutter
•Wide dynamic range
•Increasing depth of field
