6.3.3 No-Shutter mode with external trigger
In this mode, the accumulation and readout is activated by an external trigger pulse. The
exposure period depends on the trigger interval and if the trigger interval becomes longer, the
sensitivity is increased.
To use this mode:
Set function
Trigger mode, No-Shutter
TR=0
Trigger origin, external
TG=1
Trigger input
TI=0 or 1
Important note:
In this mode, the shutter cannot be used.
Only gain based one-push white balance functions (WB) are available with this mode.
The jitter generated in the trigger input causes a variation of exposure time.
