OUTLINE
The XC-ST50/50CE and XC-ST30/30CE are compact, lightweight, black and white cameras 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 type CCD) and the XC-73 (installing a 1/3 type 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 capture the image of a high-speed moving object
using an external signal. This enables a still image to be read in arbitrary timing. These two models are compatible
with each other, providing comparable fit and function. 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 external rear panel for improved operability and have an internal configuration which allows for significant
shock and vibration resistance, enabling easy incorporation into machine vision equipment.
MAIN FEATURES
1/2 type, 1/3 type 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 produces one still image a field. This feature allows the image of a high speed moving
object to be captured.
Restart Reset (R.R) function
By inputting the HD andVD signals (2VD or more) from an external source, control of the CCD exposure time can
be performed according to the length between VD pulses.
This function is used for long exposures and strobe with frame image output.
Synchronization system: Internal/external HD/VD, andVS
(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 DIP switches.
Almost all switches are located on the rear panel. This feature allows control settings to be easily made after
equipment is installed.

Compatibility
These models are the same size and provide the same 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.

External trigger shutter
By inputting an external trigger, the image of a high-speed moving object can be captured in 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 camera switches to normal (continuous) video operation.
There are two modes for timing in which a video signal is obtained.
•Mode 1 (Non-reset mode)
In this mode, an output video signal is synchronized with the VD signal after the triggered exposure is
complete.
•An output video signal synchronized with the externalVD signal when an external HD/VD signal is input.
•An output video signal 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 soon after exposure is complete.
*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 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
external equipment. To enter this mode, set DIP switches 6, 7, and 8 on the rear panel of the camera as shown in
the table below.
Long exposure
Restart Reset is especially effective for Long Exposure.
A clear 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 period (T) 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 external equipment.
Avoid lighting the scene during the light-emitting inhibit zone (see Note 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 use a 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 external equipment. Be sure to input both HD andVD 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: Normal operation 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 to 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 external equipment. Be sure to input both HD and VD signals in this case. The
phase of the VD signal must 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: An externalVD signal must be input between 10 µs and 100 ms from the falling edge of a trigger pulse (as
shownby1and 2in the figure). Forthe input (exceptdescribedabove),theoperationcannot be ensured.
*5: When the external trigger shutter mode changes to normal operation mode, one WEN signal is output.
Note
: An image is superimposed when the next exposure ends before the previous image is output.
