Overview
Overview
The DFW-SX910 with its 1/2-type PS IT CCD, and the
DFW-X710 with its 1/3-type PS IT CCD are high-
resolution industrial-use digital video camera modules.
The IEEE1394–1995 digital interface realizes a
transfer speed of 400 Mbps and outputs SXGA (1280
× 960)/YUV (4:2:2)/7.5 fps with the DFW-SX910,
XGA (1024 × 768)/YUV (4:2:2)/15 fps with the DFW-
X710. In addition, the DFW-SX910/X710 also adopts
a primary color filter CCD to realize good color
reproducibility, as well as a square pixel CCD to
eliminate the need for aspect ratio conversion in the
image processor.
Main Features
The DFW-SX910 video camera module
utilizes a 1/2-type PS IT CCD, and the DFW-
X710 utilizes a 1/3-type PS IT CCD
High-speed digital interface IEEE1394
The transmission speed is 400 Mbps. The DFW-
SX910 can output a digital image at 7.5 frames per
second; the DFW-X710 can output a digital image at
15 frames per second.
What is the IEEE1394?
The IEEE1394 is the standard serial bus for sending
and receiving digital data. It is prescribed as “IEEE*
Std. 1394-1995 IEEE Standard for a High Performance
Serial Bus.”
High-resolution
The most outstanding feature of this interface is that it
realizes transfer speeds of up to 400 Mbps and can
handle large image data size. The interface is also
capable of “Isochronous transmission” which transmits
data real-time, for up to 64 channels. Connectors can
be inserted and disconnected while the unit is turned
on, and no terminators and no ID settings such as those
necessary for the SCSI interface are required.
The DFW-SX910 (SXGA) has a high-resolution CCD
of 1.45 million pixels. The DFW-X710 (XGA) has a
high-resolution CCD of 800,000 pixels. Because the
CCDs are square pixel CCDs, you don’t need to
convert the aspect ratio in your image processing.
External trigger function
* The Institute of Electrical and Electronics Engineers, Inc.
The external trigger shutter function allows the image
exposure to be coordinated with external equipment
and moving objects.
For exposure time, the unit is equipped with Trigger
Mode 0, which indicates the length of the exposure
using the shutter parameter, and Trigger Mode 1,
which controls exposure time by the width of the
trigger signal.
It is also able to utilize a software trigger initiated by a
command from a program running on a host computer.

White Balance
IIDC Standard Features
Following features are defined by the IIDC standard,
v1.30. Only the Trigger feature is defined by the IIDC
standard, v1.31.
This feature adjusts the color balance of the camera to
ensure that a white subject appears white in the video
image. Both manual and automatic settings are
available.
There are two automatic white balance modes; Auto
White Balance and One Push White Balance.
In the Auto White Balance mode, the camera senses
any change in lighting and automatically adjusts White
Balance accordingly. In the One Push White Balance
mode, the White Balance is adjusted automatically
once and fixed until you perform the adjustment again.
The camera’s internal circuits integrate the image data
within a defined area, using an algorithm that
approximates the average value to white. Because of
this algorithm, depending on the lighting environment,
a white subject may appear other than white in the
Auto White Balance mode.
We recommend that you shoot a white subject so that
white fills the entire screen in the specified lighting
environment and then perform the One Push White
Balance adjustment. When the calculation is
completed, the White Balance in this lighting
environment is adjusted.
Brightness
This feature makes fine adjustment of the black level
possible.
Auto Exposure
This feature automatically adjusts the gain and shutter
settings, based on the brightness of the subject. To use
this feature, set the camera features and the video
format/mode as follows. This feature may not function
properly in any other settings.

For details on Auto Exposure, see page 8.
For long exposure times
This feature sets exposure time. Both manual and
automatic settings are available.
When the automatic setting is selected, Shutter is
adjusted automatically, based on the brightness of the
subject.
When exposure times longer than the currently set
frame rate cycle are set, the camera enters the long
exposure time mode, and the actual frame rate is
slowed in accordance with the exposure time.
At this time, the reference level (target point) of the
brightness is set in the Auto Exposure register.
With manual setting, the camera uses relative control
values indicated by a 12-bit integer and absolute
control values indicated using a 32-bit floating point
number.
Absolute control values for Shutter
Control of exposure time using absolute values is
possible. The values are indicated using a 32-bit
floating point value. (Unit: sec.)
The control steps are synchronized with the pixel
clock, and as the pixel clock is 15.25 MHz, one step is
approximately 65.6 ns.
Relative control values for Shutter
The range for these values extends from
10 microseconds to 17.5 seconds.
The relationship between the parameter and the
exposure time is given by the following formulas.

Functions
AbsoluteShutterOffsetAddress is an offset address for
the absolute value control. See page 26 for the formula
for the offset address.
The change in shutter time will be used when the next
exposure starts. The current exposure will complete
with the previous shutter setting. This is true for all
exposure; short or long. If you intend to reflect the
new setting immediately, stop the output and start it
again.
Trigger Shutter
This feature allows you to control the exposure timing
via a external signal input (Hardware Trigger) or via a
command sent from application software (Software
Trigger). There are two trigger modes:
– Trigger Mode 0 where the exposure time is
controlled by the shutter parameter
– Trigger Mode 1 where the exposure time is
controlled by the trigger pulse width.
In both modes, the leading edge of the hardware
trigger starts the exposure. In Trigger Mode 0, the
maximum exposure is limited by the shutter parameter.
In Trigger Mode 1, there is no limit to the exposure
time.
Gain
This feature adjusts the brightness of the picture. Both
manual and automatic settings are available. The
variable range extends from 0 to 18 dB.
When automatic setting is selected, Gain is adjusted
automatically, based on the brightness of the subject.
At this time, the reference level (target point) of the
brightness is set in the Auto Exposure register.
For details on Auto Exposure, see page 8.
Software Trigger is defined by IIDC Standard, v1.31.

It is possible to trigger the cameras at full frame rate
using hardware trigger. (This was not possible with
the earlier DFW-SX900/X700 because the trigger in
would not be accepted until after the previous images
was output from the camera.) It is very important that
the exposure not end before the previous image is out
of the cameras. If the camera is trigger too fast or
there is noise on the trigger line that will cause the
exposure to end before previous image is output, you
will get double exposure of the image.

Functions
Using the CameraInitialize command, the setting
Pan/Tilt
information stored in the channels is cleared and the
camera features and the video mode are reset to their
initial values. To preserve the information in the
channels, be sure not to send the CameraInitialize
command while driver software or application
software is starting up.
Pan/Tilt is a feature to move a region of interest (ROI)
image (smaller than the full image) vertically and
horizontally about the full image of the camera. When
the ROI image is defined (use the video mode setup),
the ROI is centered in the full image.
The value saved for Pan/Tilt is initialized when the
video mode is changed. To preserve the value, be sure
not to change the video mode while driver software or
application software is starting up, or before sending
the video start command.
Optical Filter
Normally, Optical Filter is the feature which switches
electronic optical filters, such as an ND filter or a color
conversion filter. However, on this camera, the feature
chooses the preset values of White Balance. If 0 is set,
White Balance for 3200 K is utilized. If 1 is set, White
Balance for 5600 K is utilized.
This feature is effective when the color temperature of
the shooting environment is 3200 K or 5600 K.
Memory Channels
The camera is equipped with two channels of
nonvolatile memory to hold camera settings. The
settings of all camera features and the video mode can
be stored. The camera memorizes the channel most
recently used to read out the setting information, and
retains it, even if the power is turned off. Therefore,
the camera loads the information from that channel
when the power is turned on.
The video mode settings are loaded only when the
power is turned on.
To start up the camera with the desired setting,
perform the following procedure.
1 Make changes to the camera features or the video
mode settings.
2 Store the current setting in Memory Channel 1 or
Memory Channel 2.
3 Load the information that was stored in step 2.
When you start up the camera the next time, the
settings that you have just made will be loaded
automatically.

Functions
Partial Scan
The Partial Scan feature for outputting a small part of
the full image called a Region of Interest (ROI). The
ROI can be defined as any single contiguous rectangle
that can be drawn on an even 16×16 grid of the whole
image. The Unit Cell is the smallest region of interest
that can be defined as is one of the rectangles on the
even 16×16 grid.
DFW-SX910 unit cell = 80×60 pixels
DFW-X710 unit cell = 64×48 pixels
Cutting by Partial Scan mode
Horizontal (Horizontal Direction)
The frame rate of the camera can be increased by
reducing the number of vertical lines output. In Partial
Scan mode, the frame rate is determined by the
exposure/shutter time plus the time to transmit the
image. In free run mode, the exposure starts after the
last image is transmitted. In triggered mode, the
exposure can be overlapped with the image output but
care must be taken to ensure that the exposure end
does not occur before the ouput of the previous image.
To use the Partial Scan feature, set Format7, Mode0.
In Partial Scan mode, you can select from among
Mono8, YUV4:1:1, and YUV4:2:2 as the color coding.

Memory Shot
Memory Shot allows the camera to collect one or more
images into on-board image memory without tying up
available 1394 bus bandwidth. Normally, a 1394 IIDC
camera transmits a new image immediately after the
acquisition so the 1394 bus bandwidth is pre-allocated
to the camera to ensure deterministic performance.
1394 bus bandwidth is allocated based on resolution
and frame rate assigned. Multiple camera

synchronization system. The 1394 bus is a shared
resource with finite bandwidth. The number of
cameras that can be simultaneously is limited by the
ISO bandwidth available (~32 MBytes/sec) and ISO
channels (4-8 depending on your computer 1394
interface). Bandwidth is allocated based on the
resolution and frame rate selected for the camera. To
reduce the bandwidth for a camera, reduce the output
image size and/or the frame rate.
For instance, if a camera is to transmit 1280×960 in
YUV4:2:2 at 7.5 fps, approximately 18.4 MBytes/sec;
more than half the available bandwidth. Reducing the
frame rate to 3.75 fps reduces the bandwidth to
approximately 9.2 MBytes/sec allowing 3 cameras to
transmit simultaneously.
CPU operation timing can cause jitter in the 1394 bus
synchronization of approximately 4 microseconds.
External hardware (trigger) synchronization can be
used to ensure further accuracy. To synchronize
cameras on different 1394 busses, use a common
hardware trigger to all the cameras.

One Shot and Multi
Shot
This camera supports both One Shot and Multi Shot
commands. With a One Shot command, after
outputting just one single-frame image, the camera
enters an “idling” state. With a Multi Shot command,
the camera enters the “idling” state after outputting
exactly the specified number of images.
As examples, the register settings for Format2, Mode0,
and a frame rate of 7.5 fps for the DFW-SX910, and
Format1, Mode3, and a frame rate of 15 fps for the
DFW-X710, are shown.
In addition, an isochronous transfer speed of 400 Mbps
and isochronous channel 0 are used in these examples.
Normally, set the isochronous transfer speed to 400
Mbps.
One Shot
When multiple cameras are used simultaneously, set
different isochronous channels for each one.

and Shutter automatically. However, the function
works properly in the following standard settings only.

DATA
Standard settings

B < C
DFW-SX910 Video Format: 2
Video Mode: 0
In this case, the camera tends to skip 1 frame
image, resulting in a decrease in the frame rate.
Keep this in mind when using an application that
switches exposure time frequently.
Frame Rate: 7.5 fps
Trigger: OFF
b. With a long exposure
DFW-X710
Video Format: 1
Video Mode: 3
Frame Rate: 15 fps
Trigger: OFF
In long exposure mode, the exposure time is set
longer than the image transmission cycle. In this
case, frame rate decreases according to the
exposure time.
When other modes are set, activating the AE function
is possible, however, normal operation of the function
is not guaranteed.
2. When using Trigger Mode
When this camera is set to accept a trigger at the
fastest possible timing, it can accept overlap of the
next trigger signal in the midst of video transmission.
For this reason, a trigger inhibition period is not
available. Thus, if a trigger signal is input before the
CCD can change to the state where it can accept
exposures, multiple exposures can occur, and it cannot
capture the correct image. Make sure that the
following conditions are met when the trigger is
activated.
In Trigger Mode—AE works properly when the video
format is set to the standard setting and the trigger
cycle is set to the same as that of the video format.
4. Auto shutter control and absolute value shutter
control
The auto shutter control function cannot be used in the
Absolute value control mode. When Shutter is set to
Auto, the Absolute value control mode is
automatically canceled.

DFW-SX910/X710
Appendix
5. Issues to be considered with partial activation
With partial activation, high-speed operation of the
CCD occurs.
If strong light comes into the image at the same time,
there may be some influence at the edges of the image.
In such a case then, adjust the lens so that only the
appropriate amount of light is allowed.
8. Converting Y/Cr/Cb to R/G/B
The camera outputs digital Y/Cr/Cb data. To convert
the digital Y/Cr/Cb data to R/G/B data, use following
formula.
R≈1.4022Cr+Y
B≈1.7710Cb+Y
G≈Y–0.7144Cr–0.3457Cb
6. About the address range available for
BlockWrite operations
The camera performs BlockWrite operations against
consecutive registers. However, the range of the
addresses stored in these registers are limited.
9. Timing of the change in feature setting
The change in feature setting will take effect when the
next exposure starts. When you change the shutter
setting during a long exposure, you need to note that
the change in shutter setting does not cancel the
current exposure. The current exposure will complete
with the previous shutter setting.
If you intend to start the exposure with a new shutter
setting immediately, either stop the output, then
change the setting and start the output again, or change
the setting, then stop the output and start it again.

10. Timing of the video transmission command and
that of the output
In Continuous Shot and Multi Shot modes, the bus
synchronization system works automatically.
Therefore, the timing of the acceptance of a command
does not synchronize with that of the output.
On the other hand, in One Shot mode or long exposure
mode, the bus synchronization system does not work.
Therefore, the camera starts the exposure immediately
after the video transmission command is accepted, and
the video will be output when the exposure is
complete.
User memory
If BlockWrite operations are performed outside the
ranges listed above, an address error will occur.
Meanwhile, the camera can perform BlockRead
operations for any sequence of consecutive registers
even though the registers are not available for
BlockWrite operations.
In Format7 CSR, for example, BlockWrite operations
are prohibited because Format7 CSR requires a
process for setting the register. However, BlockRead is
possible in Format7 CSR.
7. Note on the isochronous control register
The BlockWrite operations are available in the range
F0F00600h to F0F00614h. However, setting the video
mode in this range is not recommended because it may
influence the variable range available for the features.
Following the process listed below is recommended
for setting the isochronous control register.
Set the isochronous channel/isochronous speed

Timing Between External Trigger Signal and
Video Signal Output
When the Trigger Mode is set to 0, the timing will be as follows.
After the exposure time is set by the Shutter command (CSR F0F0081Ch), VD pulses will be generated inside the
camera.
Images will be isochronously output after the A period from the falling edge of the VD.
(The following figure shows an example where the frame rate is 7.5 fps for the DFW-SX910, and 15 fps for the
DFW-X710.)
