Figure 9. Pipelined Shutter Operated in Slave Mode
Triggered Global Shutter
In this mode, manual intervention is required to control
both the integration time and the start of readout. After the
integration time, indicated by a user controlled pin, the
image core is read out. After this sequence, the sensor goes
to an idle mode until a new user action is detected.
The three main differences from the pipelined shutter
master mode are:
? Upon user action, a single image is read.
? Normally, integration and readout are done
sequentially. However, the user can control the sensor
in such a way that two consecutive batches are
overlapping, that is, having concurrent integration and
readout.
? Integration and readout is user-controlled through an
external pin.
The triggered global mode can also be controlled in a
master or in a slave mode.
Master Mode
As shown in Figure 10, in the master mode a rising edge
on the synchronization pin is used to trigger the start of
integration and readout. The integration time is defined by
a register setting. The sensor autonomously integrates
during this predefined time, after which the FOT starts and
the image array is read out sequentially. A falling edge on the
synchronization pin does not have any impact on the readout
or integration and subsequent frames are started again for
each rising edge.
Slave Mode
Integration time control is identical to the pipelined
shutter slave mode, in which both integration time and
readout requests are controlled by an external trigger. An
external synchronization pin controls the start of integration.
The moment it is deasserted, the FOT starts. At this time, the
analog value on the pixel diode is transferred to the pixel
memory element and the image readout can start. A request
for a new frame is started when the synchronization pin is
asserted again.
No effect on falling edge
