Functions
Trigger mode
This mode can be set on the SHUTTER screen in the
GUI application for camera settings.
In this mode video signals begin to accumulate by
synchronizing with external trigger input. The video
signals are output after the exposure is finished.
The high-speed movement of objects can be captured
with vivid clarity in this mode.
Set the shutter speed in accordance with the recording
conditions.
Select the shutter speed from the following:
[2, 1, 1/15, 1/30, 1/60, 1/100, 1/120, 1/250, 1/500, 1/
1000, 1/2000, 1/4000, 1/10000, 1/25000, 1/50000,
Trigger Width] (sec)
When selecting Trigger Width
The mode is set to trigger pulse width detection mode.
The following is the formula for the shutter speed T[s]:
XCI-SX1: T[s] = Trigger width + 6µs
XCI-V3: T[s] = Trigger width + 5µs
You can also set the following on the SHUTTER
screen in the GUI application for camera settings:
• Trigger polarity
This is set to select a trigger input polarity for the
camera.
• Trigger delay function
This function is to delay trigger input to this unit, so
the exposure start time can be delayed until the set
time.
You can fine adjust the capture timing without
changing the camera position even after the camera is
installed.
Trigger delay setting range:
[0 to 4 (sec)] (In units of 1ms)
• Software trigger function
A trigger is generated within this unit to capture a
still image at any timing.
Binning mode
This mode can be set on the HIGH RATE SCAN
screen in the GUI application for camera settings.
This mode is used to increase the frame rate and/or
sensitivity by adding pixels in both vertical and
horizontal directions.
Select one of the following modes depending on the
binning method.
• 1
× 2 (V-binning) mode
In this mode the frame rate almost doubles and the
data volume becomes half by adding two vertical
lines.
When the shutter speed is set, the sensitivity almost
doubles.
For the XCI-SX1, the output data size becomes
1280 (H)
× 512 (V).
For the XCI-V3, the output data size becomes
640 (H)
× 240 (V).
• 2
× 1 (H-binning) mode
In this mode the sensitivity almost doubles and the
data volume becomes half by adding two horizontal
pixels.
As the horizontal synchronization signal frequency is
the same as when in normal mode, the frame rate
doesn’t change.
For the XCI-SX1, the output data size becomes
640 (H)
× 1024 (V).
For the XCI-V3, the output data size becomes 320(H)
× 480 (V).
• 2
× 2 (HV-binning) mode
In this mode the frame rate and sensitivity almost
double and the data volume becomes 1/4 by adding
two vertical lines and two horizontal pixels.
Moreover, when the shutter speed is set, the
sensitivity almost doubles again.
For the XCI-SX1, the output data size becomes
640 (H)
× 512 (V).
For the XCI-V3, the output data size becomes
320 (H)
× 240 (V).
