CXD3609R
[TRIG control]
The CXD3609R has a trigger shutter function for loading images at an optional timing. This control is different
from the conventional electronic shutter in that it is a shutter mode that it allows optional setting of the
exposure start time.
When the trigger signal is applied to the TRIG pin with control data D17 TRIGSL set to ON (trigger standby
mode), the TRIG data is loaded and reflected at the next HR falling edge.
In addition, the exposure time (shutter speed) for this control is set by TRIG data D13 to D23 TRSH and
D24 to D35 TRSG.
In standby mode, SUB rises every 1H, and the charge accumulated in the sensor is constantly discarded. In
addition, the V clocks (V1 to V4) also constantly operate, so the undesired charge inside the vertical CCD is
eliminated.
Therefore, the SG pulse stops until the external trigger is input, which means that the video cannot be
monitored until the external trigger is input and signal readout is performed. After the external trigger is input,
the preset number of shutter pulses and SG are generated. Note that when the serial data specifies number of
SUB pulses > SG generation position, operation is the same as when number of SUB pulses = SG generation
position.
When the SG position is not input 2H or more before the VR falling edge, VR is not accepted internally and
trigger drive continues.
When exposure is completed under any conditions other than the above, the exposure charge is transferred
and output using the falling edge of VR as the reference. In this case, V1 to V4, CLPDM, CLPOB, PBLK and
other pulses outside the readout block are output in the same manner as progressive scan mode. When
transfer finishes, the trigger standby mode repeats.
Note that during trigger standby mode and trigger drive, serial data other than the following are not accepted,
regardless of VR. In addition, TRIG is not accepted during trigger drive.
