Datasheet
In Figure 15, we schematically indicate the relative shift of the integration times of
different lines during the rolling shutter operation. Each line is read and reset in a
sequential way. The integration time is the same for all lines, but is shifted in time. The
integration time can be varied through the I
_
register (in number of lines).
NT
TIME
This indicates us that all pixels are light sensitive at another period of time, which can
cause some blurring if a fast moving object is captured.
When the sensor is set to rolling shutter mode, the input S
and S
should
S_START
S_STOP
best be held low.
3.9.2 Snapshot (synchronous) shutter
A synchronous (global, snapshot) shutter solves that inconvenience. Light integration
takes place on all pixels in parallel, although subsequent readout is sequential.

Figure 16: Synchronous shutter operation
Figure 16 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 is carry out in serial, which causes that no
integration is possible during read out.
During synchronous shutter the input pins S
and S
are used to start and
