OUTLINE
The XC-ST50/50CE and XC-ST30/30CE are compact, lightweight, black-and-white camera modules of a new
concept, which are produced as input devices for image processing by using the latest technology. These models
inherit the basic functions of the XC-75 (installing a 1/2-inch CCD) and the XC-73 (installing a 1/3-inch CCD),
which are used in various types of devices and systems and win popularity in the machine vision field. The XC-
ST50/50CE and XC-ST30/30CE provides an external trigger shutter that can catch a high-speed moving subject
using an external signal. This enables a still image to be read in arbitrary timing. These two models are compatible
with each other, thereby functioning in the same cabinet and by the same operation. The user can select a model
according to the conditions of subjects and optical conditions. In addition, the XC-ST50/50CE and XC-ST30/30CE
enable functions to be set on the rear panel for improved operability and have an internal configuration which
implements significant shock and vibration resistance, allowing easy incorporation into machine vision equipment.
MAIN FEATURES
1/2", 1/3" IT CCD
External trigger shutter function
(XC-ST50/ST30: 1/4 to 1/10,000 seconds,
XC-ST50CE/ST30CE: 1/4 to 1/8,000 seconds)
Inputting the trigger pulse gives one still image. This feature allows the capture of high-speed moving object.
Restart Reset (R.R) function
Inputting HD and VD signals (2 VD or more) continuously from the outside can catch one image at arbitrary time
and control the exposure time of CCD.
This function is used for long exposures and strobe with frame image output.
Synchronization system: Internal/external HD/VD, and VS
(VS is used only during external synchronization.)
Inputting an HD/VD signal from the outside automatically establishes external synchronization.
This function is effective for controlling multiple cameras efficiently from the external system.
Setting each mode on rear panel:
The setting of each mode can be changed by selecting DIP and rotary switch.
Almost all switches are located on the rear panel. This feature permits easy setting after equipment is installed.
Compact and lightweight
C-mount
Excellent shock and vibration resistance
Compatibility
These models are the same in the size and functions as the XC-ST70. They can be operated in the same way as
the XC-ST70 (installing 2/3-inch CCD). Therefore, they provide high compatibility.

ELECTRONIC SHUTTER
External trigger shutter
By inputting an external trigger, a high-speed moving subject can be caught at an exact position.
Set DIP switches 6, 7, and 8 on the rear panel to mode 1 or 2.(Refer to the table below.)
When the trigger pulse width is 1/3 sec or more, the output signal is switched to a normal video signal.
There are two modes for timing in which a video signal is obtained.
•Mode 1 (Non-reset mode)
In this mode, a video signal synchronized with a VD signal is output after a trigger pulse is input.
• A video signal is synchronized with the external VD signal when an external HD/VD signal is input.
• A video signal is synchronized with an internal VD signal when no external HD/VD signal is input.
•Mode 2 (Reset mode)
In this mode, a video signal is output from a trigger pulse after a certain period of time.
*For more details of each timing chart, refer to pages 16 to 23.
Setting of external trigger shutter speed
There are two ways to set the shutter speed.
•Using DIP switch on the rear panel
•Using trigger pulse width
Set all of DIP switches 1 to 4 on the rear panel to 0.
•An arbitrary shutter speed can be obtained by setting the trigger pulse width to the range of 2 µsec to 250
msec. Exposure time = Trigger pulse width + 97 µsec (XC-ST50/ST30)
120 µsec (XC-ST50CE/ST30CE)

RESTART RESET (R.R)
The information on one screen can be extracted at any time by inputting a restart/reset signal (HD/VD) from the
outside. To enter this mode, set DIP switches 6, 7, and 8 on the rear panel of a camera as shown in the table below.
The setting is especially effective for the following operation.
Long exposure
A high-sensitivity image is obtained by extending the exposure time of the CCD when satisfactory sensitivity
cannot be obtained under ordinary operating conditions or when observing the trail of a moving object.
The exposure time is determined by the VD interval (T) period between external VD pulses as follows.

Exposure time for Odd field
Exposure time for Even field
Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside.
Avoid lighting the scene during the light-emitting inhibit zone defined below. (The field is transfered to the
storage area of the CCD, so it can be read out.)
: For best performance, it is recommended not to flash between VD and VD + 10H (XC-ST50/ST30)/
16H (XC-ST50CE/ST30CE).
Note
FRAME IMAGE OUTPUT WITH STROBE LIGHT
A full frame image with vertical resolution of 485 lines (XC-ST50/ST30) or 575 lines (XC-ST50CE/ST30CE) can be
obtained with a strobe light by firing the strobe when the exposure time of the two fields overlap.

HD/VD input
•Continuous HD/VD input
*1: This is a signal input from the outside. Be sure to input both HD and VD signals in this case.
*2: Exposure time Te Te = Trigger width + 97 µs (XC-ST50/30)
Te =Trigger width + 120 µs (XC-ST50CE/30CE)
(The trigger width should be between 2 µs and 1/4 s)
*3: The normal operation state is engaged when the trigger high period exceeds 1/3sec.The external trigger
shutter operation is engaged when the trigger pulse goes “low”.In this case, the area between the falling
edge of a trigger pulse and the subsequent 50 ms period is an external trigger input inhibition area.During
the trigger inhibit period, an input trigger may be missed.
*4: In all cases the WEN signal indicates when a valid image is available. Normally, an image is output after
the external falling edge.If the falling edge of the trigger is very close to the falling edge of the externalVD,
there may be a delay of 1VD in the output. The period of uncertainty is when the falling edge of VD is
between 65 µs before or 10 µs after the falling edge of the trigger.
*5: When the external trigger shutter mode changes into the normal operation mode, one WEN signal is
output.
Note
: An image is superimposed when the next exposure ends before the previous image is output.

HD/VD input
•Continuous HD input and singleVD input
*1: This is a signal input from the outside. Be sure to input both HD and VD signals in this case. Make the
phase of the VD signal coincide with the falling edge of the HD signal during input operation.
*2: Exposure time Te Te = Trigger width + 97 µs (XC-ST50/ST30)
Te =Trigger width + 120 µs (XC-ST50CE/ST30CE)
(The trigger width should be between 2 µs and 1/4 s)
*3: Thenormal operation state is engaged when the trigger high periodexceeds1/3sec.After that theexternal
trigger shutter operation is engaged when the trigger pulse goes “low”. In this case, the area between the
falling edge of a trigger pulse and the subsequent 50 ms period is an external trigger input inhibition area.
During the trigger inhibit period, an input trigger may be missed.
*4: Be sure to input an external VD signal between 10 µs and 100 ms from the falling edge of a trigger pulse
(as shown by 1and 2in the figure). For the input (except described above), the operation cannot be
ensured. If the external VD signal is not input under the prescribed conditions, the normal operation is
engaged several V after a change in input operation under the prescribed conditions.
*5: When the external trigger shutter mode changes into the normal operation mode, one WEN signal is
output.
Note
: An image is superimposed when the next exposure ends before the previous image is output.
