Overview
the cameras, or exposure starts on all the cameras
simultaneously using a software trigger.
The six models of the XCD-series digital camera
modules (Black and white models and RAW color
models) employing the IEEE1394b-2002 standard are
equipped with quality digital camera features.
Although it is compact, the camera allows high-speed
image transfer and daisy chain connection with two
IEEE1394b connectors. The camera also has versatile
features such as hardware preprocessing in the camera
that reduces the load of image processing in a PC, bus
synchronization, and broadcast delivery of commands.
The XCD-series digital output cameras conforming to
the IIDC 1.31 protocol take full advantages of
IEEE1394 capabilities.
Main Features
High image quality, high-speed image
output
The image device, output frame rate and resolution of
the cameras are as follows:
XCD-V60/V60CR: 1/3-type PS IT CCD, 90 fps, VGA
XCD-SX90/SX90CR: 1/3-type PS IT CCD, 30 fps,
SXGA
XCD-U100/U100CR: 1/1.8-type PS IT CCD, 15 fps,
UXGA
Memory channel
The memory channel allows storage of up to 15 sets of
camera settings such as gain and shutter.
Bulk trigger mode
The Bulk trigger mode allows output of multiple images
with a shot of a trigger signal. Each image is shot with
the camera settings stored in the memory channel. Up to
15 image settings are possible.
Memory Shot
The image exposed from the sensor is stored in the
camera’s built-in memory. The stored image can be read
out using a command from the host PC when required.

Overview
Daisy chain connection
The camera is equipped with two IEEE1394b
connectors that support connection of multiple cameras.
As the power can be supplied from a 12-pin connector
(EIAJ), the camera achieves daisy chain connection
without limitation of power supply capacity so that a
simple image processing system with multiple cameras
can be developed.
Hardware preprocessing
The camera is equipped with hardware LUT (Lookup
Tab le).
The black and white models are also equipped with 3 ×
3 pixel matrix operation.
Bus synchronization
The cameras connected to the same bus automatically
operate in synchronization with the 1394 bus, without
using an external sync signal. The exposure timing on
multiple cameras is synchronized correctly via the
IEEE1394b cable only.
Partial scan
Partial scan clips a required angle of view (area) from
the entire screen to be read out. As a part of the image is
read out, the unit takes advantage of reduced image data
and high-speed transfer. The minimum clipping unit is
32 pixels × 24 lines.
Binning
Binning increases the sensitivity and frame rate based on
mixing the pixel data.
9-pin connector with fixing screws
Low power consumption, vibrationresistant structure, and compact size
IIDC Ver.1.31 protocol compliant
Broadcast delivery of commands
The camera settings for all the cameras connected to the
same bus can be changed at the same time. For example,
the gain or shutter speed is set to the same value on all

Functions
16 s
Gain
Both Manual and Auto Gain settings are available with
this camera.
Functions
The variable range extends from 0 to 24 dB for the black
and white models or from 0 to 18 dB for the color
models. The camera is designed so that the gain can be
subdivided and set by 0.0359 dB.
At the factory default setting, the gain is set to 0 dB.
When Auto Gain is selected, the gain is adjusted
automatically, based on the brightness of the subject. At
this time, the reference level (target point) is set in the
AutoExposure register.
For details on AutoExposure, see “Auto Exposure” on
page 9.

When Auto Shutter is selected, the exposure time is
adjusted automatically, based on the brightness of the
subject. At this time, the reference level (target point) is
set in the AutoExposure register.
For details on AutoExposure, see “Auto Exposure” on
page 9.

1150
Shutter
This camera allows both Manual and Auto Shutter
settings.
The variable range extends from 10 microseconds to
16.0 seconds; relative values are indicated by a 12-bit
integer, and absolute values are indicated using a 32-bit
floating point value.
The relationship between the parameter and the
exposure time is given by the following formulas,
where:
P = Parameter (003h to 47Eh)
E = Exposure time (s)
If P= 3
E = 0.00001
If 4 <= P <= 1000
1
If 1000 <= P <= 1150
For long exposure times
When the exposure time is longer than the frame period,
the camera enters the long exposure time mode, and the
actual frame rate is reduced in accordance with the
exposure time.
Absolute Value Control for the Shutter
This camera allows control of exposure time using
absolute values. The values are indicated using a 32-bit
floating point value. (Unit: sec.)
The variable range of absolute values extends from 10
microseconds to 16.0 seconds.
Programming example
union
{
DWORD dwValue; // 1394 is expressed in quadlets,
float fValue; // exposure time is indicated in seconds.
} AbsoluteShutterValue;
Setting examples
3 (003h) : 10 µs (1/100000)
32 (020h) : 1 ms (1/1000)
100 (064h) : 10 ms (1/100)
1000 (3E8h) : 1 s
1010 (3F2h) : 2 s
1150 (47Eh) : 16 s
8
AbsoluteShutterValue.fValue = Exposure time;
WriteQuad(AbsoluteShutterOffsetAddress,
AbsoluteShutterValue.dwValue);
WriteQuad is a virtual function used to write in the 1394
register.
AbsoluteShutterOffsetAddress is an offset address for
the absolute value control.
See “ConfigurationROM” on page 17 for the formula
for the offset address.
Auto Exposure
Lookup Table
AutoExposure is a function that automatically adjusts
the gain and shutter settings, based on the brightness of
the subject. When the gain or shutter is set to Auto, the
brightness is adjusted automatically to the value
specified with AutoExposure.
Gamma
This camera uses the gamma function to select the
lookup table.
0: Linear
1: Reverse
2: Equivalent of Gamma = 0.70
3: User setting
To set an arbitrary gamma curve, prestore the setting
values in the lookup table (EEPROM) of the camera.
The lookup table of this camera consists of 1,024 tables
with10-bit input and 10-bit output.
The lookup table allows setting of an arbitrary gamma
curve or binary segmentation.
Functions
3 × 3 Image Filter
For black and white models only, simple image
processing using the 3 x 3 image filter is possible on
hardware.
0: Filter OFF
1: Sharpness enabled
2: Horizontal edge detection (Type 1)
3: Vertical edge detection (Type 1)
4: Horizontal edge detection (Type 2)
5: Vertical edge detection (Type 2)
6: Edge emphasis (Type 1)
7: Edge emphasis (Type 2)
8: User setting
Note
Sharpness is disabled when the 3 × 3 image filter is set
to 0, or 2 to 8.

Trigger
Trigger
Trigger shutter is useful for capturing images in
response to a trigger that starts the exposure to match a
preset timing. It can also be used to capture an image
using multiple cameras with the same timing.
When a trigger shutter is used, the required trigger is
input via the 12-pin connector on the rear panel. The
Functions
input signal is a 5 to 24 V negative pulse.
As the input connector is pulled inside of the camera, the
camera can receive a trigger only by short-circuiting the
input pin and ISO (GND) pin.
Note
To connect to ground, use a device having a minimum
pulse width of 10 microseconds and an input current of
0.5 mA or more.

As this camera is equipped with 15 memory channels, a
repeat pattern of up to 15 image shootings can be set for
High level: 5 to 24 V DC
trigger mode 14 or 15.
The number of the repeat patterns to be set in one cycle
can be determined by the parameter of the trigger mode.
Low level: 0 to 0.44 V DC
0 V DC
Memory channel 0 is not used for the Bulk trigger mode
and the Sequential trigger mode.
Trigger mode 0
Trigger mode 0 starts exposure by detecting the falling
edge of a trigger signal. The exposure time is determined
by the shutter parameter.
Trigger
Exposure
Trigger mode 1
Trigger mode 1 controls the exposure time using the
width of the trigger signal pulse. When trigger mode 1 is
used, there is actually no limit to the exposure time.
Trigger
Exposure
The following features are loaded from the memory to
be set for shooting:
– Brightness
– Sharpness
– Saturation
– White balance
– Hue
– Gamma
– Shutter
– Gain
– Pan/Tilt
– Optical Filter
Note that the Auto mode of White Balance, Shutter and
Gain cannot be set.
Also note that Pan/Tilt is set only when the current video
mode is the same as the video mode selected when the
setting has been stored in the memory channel.
This camera can also be used with a software trigger that
issues the trigger signal via software command. Trigger
modes 0, 1, 14 and 15 can be used with software
triggers.
Trigger mode 14 (Bulk trigger mode)
Trigger mode 14 allows shooting of multiple images
with different camera settings using only one trigger
signal. The camera settings should be prestored in
memory channels.
10
Pan/Tilt
Hue (Color models only)
Pan/Tilt is a function used to move a camera up and
down or left and right. However this camera supports a
video mode much smaller than the CCD’s effective
pixels by cutting out images from the whole screen. You
can specify the portion to be cut out using Pan/Tilt
commands.
The variable range differs according to the selected
video mode.
When a video mode is changed, the pan/tilt values are
set to the default setting.
Brightness
This feature controls the black level of a video image.
Sharpness (Black and white models only)
This feature controls the image quality.
A smaller value makes the image softer, and a larger
value makes it sharper.
The Sharpness feature cannot be used together with the
3 × 3 filter.
When the white balance cannot be obtained with the R
and B level adjustment, you can change the G level by
hue adjustment. Normally use the default hue setting.
Trigger Delay
Issue of a trigger signal can be delayed from the external
trigger inside the camera.
This delay adjustment is useful to get an appropriate
shooting timing when the position of the subject is not
good at a regular trigger timing.
GPIO
A general-purpose I/O port with a 2-bit output and 2-bit
input is assigned in the 12-pin connector.
This port is used for reading information of external
switches and sensors from the camera and controlling
external devices.
The output terminal is of the open-collector type and
should be pulled outside of the camera (5 to 24 V).
Note on input
Connect to ISO (GND) using an input device with a
minimum signal width of 0.5 msec and an input current
of 0.5 mA or more.
Functions
Saturation (Color models only)
This feature controls the color density.
White Balance (Color models only)
This feature controls the white balance by setting the R
and B levels relative to the G level.
The camera also supports the Auto white balance by
which the camera automatically adjusts the white
balance.
Note on output
Use the following conditions:
Recommended pull-up resistor: 4.7 kΩ
Recommended pull-up voltage: 5 V
Minimum signal width: 0.5 msec
The camera is equipped with a protective resistor of 220
Ω. If the above conditions prove difficult in use, check
the output voltage and determine the external pull-up
resistor.
11
Strobe Control
Test Charts
A strobe control signal is assigned in the 12-pin
connector. This allows direct command of lightemission from the strobe connected to the camera and
controls the light-emission timing and the signal width.
The output terminal is of the open-collector type and
should be pulled at the strobe side. A strobe that emits

connected to the camera directly.
A color bar chart (for color models only) and a gray
scale chart can be output.

The color models of this camera series output raw data.
For these models, the correct color reproduction is not
obtained if the Bayer pattern in the application software
does not match that in the camera. The output pattern
can be set at the camera if the application is not equipped
with the pattern setting.
Trigger Inhibition
Note
Use the following conditions:
Recommended pull-up resistor: 4.7 kΩ
Recommended pull-up voltage: 5 V
The camera is equipped with a protective resistor of 220
Ω. If the above conditions prove difficult in use, check
the output voltage and determine the external pull-up
resistor. The camera is capable of outputting a signal of
about 10 microsecond width, although the rise time
depends on the pull-up resistor.
Setting AE/AWB Control Frame and Parameters
At the factory default setting, this camera accepts trigger
input quickly and no triggers are inhibited.
If the camera is used under noisy conditions with this
setting, noise may enter before a trigger input is
accepted, causing image disturbance.
If the trigger inhibition is enabled in such a condition,
the camera does not accept a new trigger until the image
output is completed and achieves stable operation.
With the trigger inhibition enabled, however, exposure
cannot be performed during image output.
Consequently, an acceptable trigger cycle becomes
longer according to the exposure time.
For example, when exposure is set to 1/30 s in 30 fps
mode, the trigger cycle becomes almost double, that is,
equivalent to 15 fps.
The detection frame for Auto Exposure and Auto White
Balance can be set.
Determine the detection frame in percentage units
taking the width and height of the output image as 100
%.
The control speeds for Auto Exposure and Auto White
Balance can also be set. Raise or lower the response
speed for each application respectively.
For Auto Exposure, the restart conditions can also be
set, that is the conditions once Auto Exposure
adjustment has concluded and after the gain and shutter
changes have been restored to a stable state, and a new
change in video image becomes visible.
In the Auto Exposure or Auto White Balance parameter
setting mode, the set frame is highlighted on the video
image.

User Free Memory
This camera is equipped with a 256-byte memory space
so the user can write and read data freely.
The written data is retained after the power is turned off.
For example, the user can name the camera and note the
installation conditions using this memory space.
The memory content is retained even if the camera
initialization is performed.
