Trigger Mode 5
This mode is the “multiple shutter pulse width mode”. The camera starts the integration of the incoming light from
the first external trigger input falling edge and exposes the incoming light until the trigger is inactive. Repeat this
sequence for the N-th (parameter) external trigger input falling edge and then finish integration. A parameter is
required and shall be one or more. (N >= 1)
3.9.10.
Trigger Mode 14
This mode is the “preset multiple shutter mode with a single trigger”.
This mode is Similar to “trigger mode 4” but the difference is that all the parameters are preset by the users using
only a single trigger. “Exposure Number”, “Exposure Duration”, and “Exposure Interval” are the parameters required
for this mode. However, the exposure duration and interval in each multiple shutter is equal and cannot be different.
Exposure duration & interval is defined by a user defined 1394 address (0xF2F10114)
3.9.11.
Trigger Mode 15
Trigger mode 15 is the new function. The user can capture as many images as they want with one external trigger
signal. This mode is called ‘One-trigger Multi-frames’. For this mode 15, the value of the shutter time should be
fixed. The mode 15 is supported by both H/W trigger and S/W trigger.
