Overview
This unit is a digital video camera module that adopts a
USB 3.0 interface for image output and camera control.
The XCU-CG160 is a monochrome models, and the
XCU-CG160C is a color model.
In this document, “Digital Video Camera Module” is
referred to as the “unit”, “XCU-CG160” as
“Monochrome camera”, and “XCU-CG160C” as “Color
camera”.
Features
USB 3.0 interface
Image output and camera control are performed over a
USB 3.0 interface.
USB3 Vision adoption
The USB3 Vision standard is adopted to enable simple
camera control.
High image quality
This unit produces stable output images, by adopting the
latest CMOS image sensors with a global shutter
function. By adopting a square pixel image sensor,
images can be processed using the original aspect ratio
without a conversion procedure.
Various settings
Various settings can be configured by sending a
command from a host device.
White balance control (color camera only)
You can adjust the R and B levels relative to the G level
to adjust the white balance. This unit is also equipped
with a one-push white balance function for automatic
camera white balance adjustment.
Area gain function
You can set the gain between 0 to 32 times for up to 16
arbitrary positions. If the set area is duplicated, the lownumbered area takes priority.
Equipped with temperature sensor
The camera’s internal temperature can be read from a
temperature sensor mounted on the module board. If the
update interval of the temperature sensor value is set to
other than 0, temperature information can be sent to a
PC application as event data.
Pixel defect correction function
This unit is equipped with a defective pixel correction
function that reduces the effect of sensor defects. It can
be switched on/off.
Shading correction function
This unit is equipped with a function that corrects the
shading caused by a light source or lens. It can be
switched on/off.
Binning function (XCU-CG160 only)
Adding two pixels in the vertical and horizontal
directions achieves higher sensitivity and frame rate.
External trigger shutter function
By synchronizing with an external trigger signal, any
shutter timing can be used.
Partial scan
The camera module can limit the number of video
output lines to achieve high frame rates, enabling highspeed image processing.
Chassis mount
Screw holes for mounting the camera module are
located under the front panel.
Mounting the camera module at this location minimizes
the deviation of the optical axis.
LUT (Look Up Table)
A LUT can be turned on/off.
When turned on, you can select from five preset values,
such as inversion, binarization, configurable five-point
approximations, etc.

Phenomena Specific to Image Sensors
Note
The following phenomena that may occur in images are
specific to image sensors. They do not indicate a
malfunction.
White flecks
Although the image sensors are produced with highprecision technologies, fine white flecks may be
generated on the screen in rare cases, caused by cosmic
rays, etc.
This is related to the principle of image sensors and is
not a malfunction.
The white flecks especially tend to be seen in the
following cases:
• When operating at a high environmental temperature
• When you have raised the gain (sensitivity)
• When using the slow shutter
Aliasing
When fine patterns, stripes, or lines are shot, they may
appear jagged or flicker.
a Video camera module (this unit)
This is a small-size, high-resolution, camera that uses a
CMOS image sensor with a global shutter function.
b Camera cable
This is attached to the DC power input connector of the
unit and is used for the power supply and exchange of
trigger signals. For details about purchasing a cable,
consult a dealer.
c C-mount lens
Use a suitable lens to fit the camera pixel count.
d DC-700/700CE Camera Adaptor
This is connected to the unit to enable power supply
from an ordinary AC power source.
e VCT-333I Tripod Adaptor
This attaches to the bottom of the unit to mount the unit
on a tripod.
f USB 3.0 interface image input board
Install the board in the expansion slot of the host device
(computer or other device).
The camera can also be connected to a USB 3.0 port on
a computer, but the use of the input board is
recommended.
This document describes the case where the input board
is used.

g USB 3.0 cable
Connect to the USB connector on the rear panel of the
unit to send image signals and to receive control signals.
Use a Standard USB A to USB Micro B, USB 3.0 cable
that is compatible with the USB3 Vision standard.
For details about purchasing a cable, consult a dealer.

a Lens mount (C-mount)
Attach any C-mount lens or other optical equipment.
Note
Use a C-mount lens where the protrusion (a) extending
from the lens mount face (b) is 10 mm (13/32 inch) or
less.
When attaching a lens to the camera, note that the
resolution of the image that is output from the camera
may vary depending on the performance of the lens.
The performance of the same lens may also vary
depending on the aperture value.
If the resolution is insufficient, adjust the aperture value.

d Camera mount reference screw holes (bottom)
These precision screw holes are for securing the camera
module. Securing the unit with these holes minimizes
any optical axis alignment offset.
For details about the size of and position of guide holes
and reference holes, see “Dimensions” (page 44).
f USB connector (Micro B type)
Connect a USB 3.0 cable to control the camera module
from a host device and to send image signals from the
camera module. Power can be supplied from a USB 3.0
interface video input board or from a USB hub over the
USB 3.0 cable.
CAUTION
• For safety, do not connect the connector for peripheral
device wiring that might have excessive voltage to this
port. Follow the instructions for this port.
• Use a Standard USB A to USB Micro B, USB 3.0
cable that is compatible with the USB3 Vision
standard.

Mounting on a tripod
To use a tripod, attach the VCT-333I Tripod Adaptor
(not supplied) to the camera module.
Use a tripod screw that protrudes (4) beyond the
mounting surface, as follows, and tighten it using a
screwdriver. Be sure that the protrusion (4) does not
exceed 5.5 mm (0.2 in.) in length.
4: 4.5 mm to 5.5 mm
Note
When attaching the tripod adaptor (not supplied), use
the screws provided with the tripod adaptor.
When mounting the camera
When the value read from temperature sensor is above
75 °C (167 °F), heat dissipation is required.
Use in environments where the difference with the
ambient temperature is 32 °C (90 °F) or less.
To facilitate heat dissipation from the unit and maintain
performance, mount the camera to a metallic plate.

Notes
• When mounting the camera on the metallic plate,
secure the camera by using the reference screw holes
on the camera (page 5) and screws.
• Do not mount the camera on a plate made of a
material, such as wood or resin, that prevents heat
dissipation.

Trigger Signal Input
Trigger signals can be input via pins 2, 3, and 4 of the DC power supply input connector, or by software command.
Switchover of the trigger signal can be changed using TriggerSource. For details, see “Trigger Control” (page 17).
Trigger signal polarity
Positive polarity refers to a trigger signal activated by a Low to High rising edge, or High-level interval. Negative

Partial Scan
Binning (XCU-CG160
Only an area selected from the effective pixel area can
be scanned. The area size is selected by Height and
Width, and the read start point is selected by OffsetX
and OffsetY. Reducing Height increases the frame rate,
but changing Width does not change the frame rate.
Partial scan can be set with or without a trigger.
OffsetX and OffsetY relate to Width and Height as
follows:
OffsetX + Width ≤ Width (maximum value)
OffsetY + Height ≤ Height (maximum value)
Note
Since the shutter setting has priority, use a shutter speed
high enough to enable partial scan at a higher frame rate.

Camera Mode
“FAST” mode prioritizes the frame rate, and is set by
default.
The frame rate upper limit of “FAST” mode is higher
than for “NORMAL” mode, but the available functions
are limited.
When correcting defects/shading in “FAST” mode,
detect and save the defects/shading in “NORMAL”
mode and then return to “FAST” mode.
Reboot the unit to apply the change in camera mode.
