Burst trigger

Exposure can be repeated with a single trigger signal. Two modes are available: a mode that repeats a single exposure
time and a mode that alternately repeats two exposure times. You can specify the number of exposures and the interval
between repeatedly setting the trigger signal on.

Exposure
ExposureTime
The continuous exposure ends when either one of the following conditions occurs.
• Trigger signal Off is detected
• The number of times of exposure reaches the number specified in BurstFrameCount
Upon trigger edge detection
Upon trigger width detection
Upon trigger width detection
Exposes only the number of times set in BurstFrameCount.
Performs burst exposure while the input trigger is on. However, burst exposure is
terminated when it reaches BurstFrameCount.
Enabled when ExposureMode is in edge detection mode. Disabled in width detection
mode.
0: Repeats continuously
1 or more: Exposure for designated number of times
Forced termination of repeated exposure
Value to determine the second exposure time of trigger width detection. The first
exposure time (trigger width) multiplied by this value is the second exposure time.

Setting
Exposes for the period set in ExposureTime.
Exposes for the range of trigger width.
Exposes for periods set in ExposureTime and
ExposureTime2 alternatively.
Exposes for periods in trigger width and trigger width
× Exposure2Ratio alternately.
