3.6 Synchronous shutter
In a synchronous (snapshot) shutter light integration takes place on all pixels in
parallel, although subsequent readout is sequential.
Figure 8 shows the integration and read out sequence for the synchronous shutter. All
pixels are light sensitive at the same period of time. The whole pixel core is reset
simultaneously and after the integration time all pixel values are sampled together on
the storage node inside each pixel. The pixel core is read out line by line after
integration.
Note that the integration and read out cycle can occur in parallel.
The control of the readout of the frame and of the integration time are independent of
each other with the only exception that the end of the integration time from frame I+1
is the beginning of the readout of frame I+1.
