Overview
Overview
The XCL-X700/V500 is a monochrome digital video
camera module. This camera module outputs digital
images utilizing LVDS via the digital interface
connector.
What is the Camera Link?
The Camera Link is specifications defined for
industrial cameras, and the term used collectively
forcall products meeting these specifications. In the
Camera Link specification, digital parallel signals are
converted to LVDS serial signals and sent out from the
camera module. These signals are sent to the interface
board for the camera (frame grabber) via the cable, and
decoded to the original digital parallel signals in the
interface board. The XCL-X700/V500 is equipped
with a connector compatible with the Camera Link
specifications, and can be connected to any interface
board compatible with the XCL-X700/V500 using the
specified standard cable.
High image quality
The XCL-X700 (XGA) has a progressive scan CCD of
800,000 pixels. The XCL-V500 (VGA) has a
progressive scan CCD of 330,000 pixels. Both cameras
produce high-resolution images. By adopting square
pixels, images can be processed using the original
aspect ratio without a converting procedure.
Various mode settings
Sending a command from the host device allows the
following mode settings.
• Gain
• Read mode: normal /binning
• High rate scan
• Synchronized input/output
• 75 Ω termination
• Shutter: Normal/Trigger shutter
• Shutter speed
External synchronization
Features
Digital interface connector
Equipped with a Camera Link compatible connector.
The XCL-X700 can output a digital image at 30
frames per second; the XCL-V500 can output a digital
image at 60 frames per second.
XCL-X700/V500
HD (horizontal drive), VD (vertical drive) signals: The
camera module automatically detects the HD and VD
signals input and externally synchronized with those
signals.
Setting the operating speed by inputting
an external clock
You can operate the camera module at the desired
clock frequency (frame rate) by inputting external
clock signals of an arbitrary frequency from normal to
1/2.
4
Internal sync signal output
You can output HD or VD signals from the 12-pin
connector by changing the setting using a command
sent from the host device.
Electronic shutter function
Shutter speed can be selected from a wide range or in
flickerless (FL) mode.
External trigger shutter function
(1/4 to 1/100000 sec.)
You can obtain a freeze picture by inputting an
external trigger. This function is useful to shoot a fastmoving object clearly.
Overview
High rate scan
The camera module can limit the number of effective
video output lines to achieve high frame rates,
enabling high-speed image processing.
Binning
By “binning” two pixels that align vertically, you can
acquire sensitivity as well as a frame rate twice as high
as those in the normal mode, when using the electronic
shutter.
Body fixing
The screw holes to install the camera module are
located under the front panel (the CCD reference
plane). Installing the camera module using these holes
minimizes deviation of the optical axis.
Note
The CCD is driven at high speed during a High-rate
scan or Binning operation. In this situation, if intense
light is input to the camera, the peripheral areas of the
video image may be affected. In such a situation,
adjust the amount of light using the iris.

About the Camera Functions
Functions of the XCL-X700
■ Electronic Shutter Function
Normal Shutter
The electronic shutter is used for continuous video
output to capture fast-moving objects clearly. Shutter
speeds of 1, 1/100, 1/125, 1/250, 1/500, 1/1000, 1/2000,
1/4000, 1/10000, 1/20000 second are supported. Normal
Mode is supported for the Camera Mode.
External Trigger Shutter
The electronic shutter is used synchronized with
externally input trigger signals to capture fast-moving
objects clearly and in a precise position. There are two
types of external trigger shutter: an external trigger
shutter controlled by external input trigger pulse width
and a fixed speed external trigger shutter synchronized
with the timing of an externally input trigger. Trigger
Mode1 and Trigger Mode 2 are both supported for the
Camera Mode.
• Fixed external trigger shutter speeds:
1, 1/100, 1/125, 1/250, 1/500, 1/1000, 1/2000,
1/4000, 1/10000, 1/25000, 1/50000, 1/100000
second are supported.
controlled by external trigger pulse width:
You can obtain an arbitrary shutter speed by setting
the external trigger pulse width to the range of 2 µsec
to 1/4 sec.
- When trigger signals are input through the 12-pin
connector
External trigger pulse width shutter speed = external
trigger pulse width + 6 µsec
- When trigger signals are input through the
DIGITAL IF connector
External trigger pulse width shutter speed = external
trigger pulse width + 5 µsec
■ Overlap Function
One way to increase frame rate while using slow to
mid-speed trigger pulse width shutter in the case of
previous analog cameras 1 is to input the rising edge
of the external trigger signals during the effective
image interval as indicated in case 2. Noise is
generated when the rising edge of the external trigger
signal is input during the effective image interval,
however, and the effective video output deteriorates
and becomes unusable. As a consequence, we must
input the signal after the effective image interval and
we cannot increase frame rate indicated as T2 in the
case of 2.
The frame rate results in:
• External trigger shutter speed is

This camera is equipped with an Overlap function
which eliminates the effect of noise accompanying the
increase of frame rate while using a slow to mid-speed
shutter. This camera module can be used in the
operation mode that can increase frame rate without
noise generation as indicated in 2 as well as that in 1
that is equal to the operation of previous analog
cameras. Thanks to this function, exposure time can be
prolonged, and shutter speed can be slowed down,
keeping a high frame rate by putting the rising edge of
the external trigger earlier as indicated by A in 2. Be
aware that the maximum interval in which you can
input the rising edge of the external trigger is in the
range of 10 H after the falling edge of the previous
trigger to the rising edge of the next trigger as
indicated by B in 2. Trigger Mode1 and 2 are
supported for the Camera Mode.
Notes
• The description above is the operation while using a
slow to mid-speed shutter controlled by the external
trigger pulse width. When using a fixed speed
external trigger shutter, be sure to input the rising
edge of the next trigger after the internal exposure
time and at the appropriate timing so as not to affect
the effective image interval corresponding to the
current trigger signal. Be aware that if this condition
is not observed, the following may occur.
- To which frames the effective images
corresponding to the external trigger signals will
be output may be inconsistent.
- Double exposure
- Signals in the blanking interval may be output in
the effective image interval.
• If you change settings such as Camera Mode while
using the Overlap function, video output may be
disturbed.
• A deviation of a maximum about 1H is generated for
the exposure time by the Overlap function, so the
supported shutter speeds are limited to those for
which this exposure deviation can be ignored.

Notes
• Be aware that the shift of phase occurs in the range of
– 2 × CLK to 0 (reference: External-CLK) for
Internal-HD signals depending on the timing when
the power is turned on. The amount of the shift is not
always the same and varies within the range
described above every time the power is turned on.
• Be aware that noise is generated when the Internal/
External clock is switched.
XCL-X700/V500
15
Functions of the XCL-X700
The speed of the electronic shutter is determined by
the frequency of the external input clock signals.
Calculate the shutter speed according to the following
formula.
Normal shutter speed:
Exposure time = { 1106 × A + 164 × (A–1) × 187 }
× 2/ECLK
Shutter speed = 1/Exposure time
A: 1 (1/20000 s)
2 (1/10000 s)
6 (1/4000 s)
12 (1/2000 s)
23 (1/1000 s)
46 (1/500 s)
93 (1/250 s)
186 (1/125 s)
232 (1/100 s)
ECLK: External clock frequency: 59 (MAX) to 29.5
(MIN) MHz
Fixed external trigger shutter speeds:
Exposure time = { A + B × 1270 + 144 } × 2/ECLK
Shutter speed = 1/Exposure time
A: 151 B: 0 (1/100000 s)
446 0 (1/50000 s)
1036 0 (1/25000 s)
2806 0 (1/10000 s)
7231 0 (1/4000 s)
14606 0 (1/2000 s)
0 23 (1/1000 s)
0 46 (1/500 s)
0 93 (1/250 s)
0 186 (1/125 s)
0 232 (1/100 s)
■ Binning Function
Mixed signals for vertically adjacent pixels of the
output of the CCD are output in this function and
sensitivity and frame rate are approximately doubled.
When the Normal shutter is OFF in the Normal Mode,
the frame rate is doubled but exposure time is halved,
so that the effect of this function is cancelled out as in
the Reset/Restart mode. Both sensitivity and frame
rate are doubled when the Normal shutter is ON.
All modes are supported for the Camera Mode.
But High-rate scan II in Trigger Mode2 is not
supported.
External trigger pulse width shutter
speed:
• When trigger signals are input through the 12-pin
connector
Exposure time = { external trigger pulse width
+ 1 µs} + 144 × 2/ECLK
•When trigger signals are input through the DIGITAL
IF connector
Exposure time = { external trigger pulse width }
+ 144 × 2/ECLK
Shutter speed = 1/Exposure time
Be aware that the external trigger pulse width should
be set in the range of 3 µsec to 1/4 sec when inputting
external clock signals.
