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.

Functions  
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.

Shutter  
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.

software can setup the multiple cameras on a single  
1394 bus on one computer for Memory Shot

image(s) are in the camera on-board memory, and tell  
each camera to transmit its stored image(s). These  
cameras have 128 Mbit of frame memory.

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  
1280×960 at YUV4:2:2 is 6 images

exactly to the actual exposure time.  
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.

Control  
The remaining 28 bits can be allocated to the camera  
as addresses, but in reality, the first 4 bits are fixed at  
0, so the largest number of bits that can be allocated to  
the camera as address space is 24 bits.  
The bus and node IDs may be changed if the topology  
is restructured because of bus reset, so only the least  
significant 32 address bits are shown in this Technical

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.

The camera memorizes the channel most recently used  
to read out the setting information using nonvolatile  
memory. Then, the information in that channel will be  
loaded when the power is turned on the next time.  
The video mode settings are loaded only when the

capture mode will be released. To find the number  
of the frames captured, read out F0F40000h. The  
end flag shows that the capture mode has been  
released.  
The Access Control Register is managed by the time-  
out control. A series of commands must be completed

DATA  
Standard settings  
A > B

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.

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.  
R1.4022Cr+Y  
B1.7710Cb+Y  
GY–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

Set the video format  
Set the video mode

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.)
