Trigger width detection

The figure shows trigger signal negative polarity (Low-level width detection).

Trigger signal

Exposure

Sensor output

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.

Trigger signal

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

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.
