Overview
Overview
The XCD-SX910CR/SX910UV/SX910 with its 1/2-
type PS IT CCD, and the XCD-X710CR/X710 with its
1/3-type PS IT CCD are high-resolution industrial-use
digital video camera modules. Utilizing an IEEE 1394-
1995 digital interface, transfer rates as high as 400
Mbps are realized. In addition, the use of digital
signals enables industrial-use image processing
without “image deterioration,” an important plus in the
industrial world. Moreover, the use of a square pixel
CCD eliminates the need for aspect ration conversion
during image processing.
Main Features
The XCD-SX910CR/SX910UV/SX910 video
camera module utilizes a 1/2-type PS IT
CCD, and the XCD-X710CR/X710 utilizes a
1/3-type PS IT CCD
RAW mode output using the RGB Bayer
pattern (XCD-SX910CR/X710CR only)
Finally, a vibration resistance feature permits use of
these units in all types of inspection and imaging
devices.
High-speed digital interface IEEE1394
High-resolution
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.”
The XCD-SX910CR/SX910UV/SX910 adopts an
SXGA-compatible 1.45 M-pixel CCD while the XCD-
X710CR/X710 adopts an XGA-compatible 800 Kpixel
CCD to produce high-picture quality images.
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.
External trigger function
The external trigger shutter function allows the image
exposure to be coordinated with external equipment
and moving objects.
* The Institute of Electrical and Electronics Engineers, Inc.
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.

Overview
Partial scan output image format
It is equipped with a partial scan feature that divides an
entire screen image into 16 × 16 sections, allowing it
to be output as an optionally designated rectangle
within the required limits.
Use of this function enables frame rates faster than
normal speeds, thus enabling efficient image capture.
In addition, partial scan operations can be carried out
even without the input of an external trigger.
C-mount
High vibration-resistance structure
Binning
The unit is equipped with a Binning mode, which
increases the frame rate and increases the sensitivity
based on mixing the pixel data on the CCD imager.
The XCD-SX910UV/SX910 provides a screen size of
640 × 480, and on-screen movement at 30 fps is
available; the XCD-X710 provides a screen size of 512
× 384, and on-screen movement of 50 fps.
Black & white (Monochrome) 16-bit mode
A Black & white (Monochrome) 16-bit mode is
available. The bits used are the least significant
(lowest) 10 bits.

Functions
For long exposure times
Trigger Shutter
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.
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 BNC connector on the rear panel. The input signal
is a 5-volt negative pulse. The falling edge of the
signal is detected as the trigger, and the unit is
equipped with an exposure time consisting of the
shutter parameter set as trigger mode 0, and trigger
mode 1 that controls the exposure timing using the
width of the trigger signal pulse. When trigger mode 0
is used, the minimum width of the trigger is 10
microseconds. When trigger mode 1 is used, there is
no limit to the exposure time.
Absolute Control Value for the
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 30.5 MHz, one step is
approximately 32.8 ns.
The range for these values extends from 10
microseconds to 17.5 seconds.
This unit can also be used with a software trigger that
issues the trigger signal via a software command. Both
trigger mode 0 and trigger mode 1 can be used with
software triggers.
Programming example;
union {
DWORD
float
dwValue;
fValue;
// 1394 is expressed in quadlets,
Trigger shutter
// exposure time is indicated in seconds.
} AbsoluteShutterValue;
AbsoluteShutterValue.fValue = Exposure time;

WriteQuad(AbsoluteShutterOffsetAddress,
AbsoluteShutterValue.dwValue);
10 µsec or more
WriteQuad is a virtual function used to write in the
register.
• Input impedance: 10 kΩ
AbsoluteShutterOffsetAddress is an offset address for
the absolute value control. See page 25 for the formula
for the offset address.
Auto Exposure
AutoExposure is a function that automatically adjusts
the gain and shutter settings, based on the brightness of
the subject. When this function is used, make sure the
video mode is set to one of the following modes. This
function is not effective in any other modes.

Functions
Pan/Tilt
Memory Channels
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. One unit of movement is two pixels.
Refer to the table for the video modes in which Pan/
Tilt commands can be used and the variable ranges for
the mode. The values in parentheses are the initial
settings.
This camera is equipped with two channels non-
volatile 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.

Functions
Partial Scan
The partial scan mode is a function for outputting part
of the full images a region of interest on the whole
image. Based on the unit cell as the unit, continuous
parts can be selected. Only rectangles can be selected.
The screen cannot be cut in convex and L
shapes.
Cutting by partial scan mode
Horizontal (Horizontal Direction)
The unit size of both the XCD-SX910CR/SX910UV/
SX910 and the XCD-X710CR/X710 is 1/256th of the
whole screen, divided into 16 sections, horizontally
and vertically.
The partial scan mode for the XCD-SX910CR/
SX910UV/SX910 and the XCD-X710CR/X710 has
had a partial read out function added, and there is a
frame rate speed-up feature for use when the vertical
width of the cut-out is small. But because of the
structure of the CCD, no matter how small the cut-out
width is horizontally, the frame rate cannot be
increased.
When Partial scan mode is used, set Format7, Mode 0.

Binning Mode
The mode used when the sensitivity is increased and
the frame rate is multiplied based on mixing the CCD
pixel data, is called the Binning mode.
There are two types of binning: 1 × 2 binning when the
output image is compressed in the vertical direction
only, and 2 × 2 binning when the image is compressed
in the horizontal direction also.
When binning mode is used, set either Format7 Mode

Synchronization
For Format 7, the offset address 600h frame rate
settings are disabled, but with this camera, the frame
rates for Modes 1 to 4 are determined by the packet
size.
Timing used to start exposure is synchronized with the
1394 bus time cycle register.
If cameras are connected in a bus connection, they are
automatically synchronized in a 1394 bus operation.
As 400 Mbps frequency area restriction can affect the
synchronization, you must set the video mode in which
the cameras can transmit video signal at the same time.
1394 synchronization does not work in long exposure
mode. In a long exposure, the exposure time is set
longer than the image transmission cycle.

Video Mode Settings
OneShot and MultiShot
Select the video mode you want to use from the tables,
and make the required settings. As examples, the
register settings for Format2, Mode2, and a frame rate
of 15 fps for the XCD-SX910CR/SX910UV/SX910,
and Format1, Mode5, and a frame rate of 30 fps, for
the XCD-X710CR/X710, are shown.
This camera supports both OneShot and MultiShot
commands. With a OneShot command, after outputting
a just one single-frame image, the camera enters an
“idling” state. With a MultiShot command, the camera
enters the “idling” state after outputting exactly the
specified number of images.
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.

When other modes are set, activating the AE function
is possible, however, normal operation of the function

c. With a long exposure
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.
In Trigger mode—AE works properly when the video
format is set to the normal setting and the trigger cycle
is set to the same as that of the video format.
4. On the sensitivity in Binning mode
2. When using Trigger mode
In the Binning mode, the vertical signal is factored in,
so the sensitivity is doubled. The frame rate is also
doubled (the frame cycle is halved), but if the shutter is
set to off, the exposure time is halved, and so this
effect is canceled out. On the other hand, when the
shutter is on, the effect of this inclusion appears, and
the sensitivity increases. So when setting the exposure
time in the Binning mode, take this into consideration.
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.

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

8. 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.
6. Issues to be considered with partial activation,
and binning
With partial activation and binning, 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.

The camera performs BlockWrite operations against

9. About the Binning mode on the XCD-SX910CR/
X710CR
On a camera using a color CCD, the color information
is lost during the process of mixing pixels. Because of
this, a color CCD camera cannot output a correct
image in the Binning mode. Use the Binning mode
only when you intend to perform something needing a
high frame rate, such as focus adjustment.

are prohibited because Format 7 CSR requires a
process for setting the register. However, BlockRead is

Appendix
On light sources
Characteristics of the
XCD-SX910UV
This camera is sensitive to ultraviolet light in the 400
nm or less. At the same time, it is sensitive to visible
and infrared light above 400 nm in wavelength. So,
when shooting a subject illuminated only by ultraviolet
light, the visible light or infrared light shining on the
subject or entering the camera, can have an influence
on the image output. In order to obtain an accurate
image, some sort of screening equipment will be
needed to deal with both the visible and the infrared
light.
Relative Sensitivity
The relative sensitivity of the camera is determined by
the permeability of the optical filter, and the
spectroscopic sensitivity characteristics of the CCD
mounted in the camera. Thus the relative sensitivity of
a camera can be found by looking at the product of the
permeability properties of the optical filter and the
spectroscopic sensitivity characteristics of the CCD.
If you use ultraviolet light as a light source, use light
waves in the appropriate range for the camera
sensitivity. Depending on the amount of light,
wavelengths shorter than 350 nm can have an effect on
the human body. Be especially careful to read the
Operating Instructions to obtain a full understanding of
how to properly use your light source.
This time, the optical filter used in the XCD-
SX910UV will allow 200 to 1000 nm wavelength
waves to pass, but for the most part, however, it
doesn’t depend on the wavelength, but instead utilizes
a certain permeability ratio. So the relative sensitivity
of the camera is more or less the same as the
spectroscopic sensitivity of the CCD.
In addition, there are safety considerations when using
ultraviolet light, involving light reflected off the
camera and light shining around at random. Be sure to
take all necessary safety precautions when you use
ultraviolet light as a light source.
When shooting a scene illuminated only by ultraviolet
light, visible light or infrared light shining on the
subject, or entering the camera can have an influence
on the image output. In order to obtain an accurate
image, some sort of screening equipment will be
needed to deal with the visible or the infrared light.
When you switch back and forth using ultraviolet light
and visible light with the same camera, due to
aberrations in the lens, there may be some differences
in the focus when you use ultraviolet light and when
you use visible light.
On the XCD-SX910UV, the flange-back is 17.526 mm
with ultraviolet light having a wavelength of 300 nm,
as the default.
When screening or covering is not possible, to shoot an
image using only ultraviolet light in an environment
where ultraviolet and visible lights are mixed, it is
necessary to change the relative sensitivity response of
the camera. In such a case, in order to suppress the
sensitivity to visible light, a special filter can be used.
This kind of special filter is called an “ultraviolet light
permeable filter.” If you set this filter between the
camera and the subject, the sensitivity to ultraviolet
light relative to visible light increases, and you can
create a camera system more responsive to ultraviolet
light.
There are many types of special filters available on the
market. You can use filters to suit the environment and
the shooting conditions, and using just this camera,
configure a camera system that has exactly the relative
sensitivity characteristics you need.

Appendix
camera change (for example, how wide you open the
lens, how long the exposure time is, how high the gain,
etc.), it is not absolutely necessary to change the CCD
as long as the desired standard of image quality
continues to be produced.
Deterioration in CCD sensitivity
The sensitivity of the CCD in this camera can
deteriorate over time.
Because ultraviolet light contains higher energy
compared to visible light, the elements making up the
CCD can suffer damage; so depending on the amount
of ultraviolet light energy accumulated, a lowering of
the sensitivity may occur. The amount of radiated
energy is equal to the amount of light radiated and the
length of time it is radiated, thus the total accumulated
radiated energy is the sum total of all the radiated
energy accumulated over time.
As an easy guideline to calculate the duration of time
which causes a 15% reduction in the sensitivity with a
196 nm ultraviolet light source (Characteristic
Example 2), we will introduce a simpler version of the
formula used above to calculate the total amount of
accumulated radiated energy.
Time which causes a 15% reduction of the
sensitivity (in years) =
The total accumulated radiated energy [J/cm2] =
Σ (Amount of radiated light [W] × length of
time it is radiated [in seconds])
0.48/ amount of radiated light [µW]
This formula is based on the amount of radiated light
under one light source, with the camera being used
continuously for 24 hours a day. For example, with
0.5 µW of radiated light, which is the standard output
from one light source, the number of years it would
take the CCD to suffer the 15% deterioration in
sensitivity necessary to require replacement is 0.96
years. So if the camera is used 8 hours a day, then the
time to replacement of the CCD is three times that, or
2.88 years.
As an example of this particular characteristic, see the
following.
Characteristic Example 1:
With ultraviolet light having a wavelength of
266 nm, and total accumulated radiated energy of
100 J/cm2, the sensitivity of the CCD will be
reduced by about 1%.
As an easy guideline to calculate the duration of time
which causes a 1% reduction in the sensitivity with a
226 nm ultraviolet light source (Characteristic
Example 1), we will introduce a simpler version of the
formula used above to calculate the total amount of
accumulated radiated energy.
This is how the sensitivity of the CCD deteriorates
from the effects of the radiation of ultraviolet light.
When the wavelength of the radiated ultraviolet light
changes, it can be assumed that the total amount of
accumulated radiated energy which causes the
deterioration in the sensitivity will vary greatly.
Please be aware that it is possible for the sensitivity to
deteriorate in a short time, too, especially when a large
amount of ultraviolet light is used. (When an
ultraviolet laser is shined directly into the camera and a
portion of the usable picture element area of the CCD
receives a significant amount of ultraviolet light, that
portion of the CCD alone can suffer from deterioration
in sensitivity.)
Even when there isn’t a significant amount of light
entering the camera, but the exposure to the light
continues for a long time, the sensitivity can be
affected. So close the shutter when not actually
shooting, and protect the CCD from ultraviolet light as
much as possible.
Time which causes a 1% reduction in the
sensitivity (in years) =
3.17/ amount of radiated light [µW]
This formula is based on the amount of radiated light
under one light source, with the camera being used
continuously for 24 hours a day. For example, with
1.5 µW of radiated light, which is the high-power
output from one light source, the number of years it
would take a 1% deterioration in sensitivity to occur
is 2.11 years. So if the camera is used 8 hours a day,
then the period is three times that, or 6.33 years.
Characteristic Example 2:
With ultraviolet light having a wavelength of
196 nm, and total accumulated radiated energy of
15 J/cm2, the sensitivity of the CCD will be
reduced by about 15%.
Because the CCD is replaceable, when you want to
replace it due to deterioration in sensitivity, contact the
store where you purchased the camera. However, you
cannot replace just the CCD, you will have to replace
the front panel block as a unit, at additional expense.
As an example of the decision standard, you can think
of a 15% reduction in sensitivity as a guideline to use
to decide when to replace the CCD. However, even
though the conditions under which you use your
