XC-ST70/70CE

OUTLINE

The XC-ST70/70CE is a compact, lightweight black-and-white camera module using the latest technology and a 2/3­inch new-generation CCD. Each mode can be set by selecting the switches on the rear panel. The XC-ST70/70CE
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. The XC-ST70/70CE meets the high-le v el needs of image inspection based
on a high-definition image utilizing a 2/3-inch CCD that is popular in the image processing field.
In addition, the XC-ST70/70CE incorporates significant shock and vibration resistance allowing it to be easily
incorporated into machine vision equipment.

MAIN FEATURES

2/3" IT CCD

External trigger shutter function

(XC-ST70: 1/4 to 1/10,000 seconds, XC-ST70CE: 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 stored 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.
All control switches on outside of camera.

Setting each mode on rear panel:
The setting of each mode can be changed by selecting DIP

Almost all switches are located on the rear panel. This feature permits easy setting after equipment is installed.

7 Internal/external sync selector

switch

The camera operates with internal syn­chronization when there is no external
sync input signal in the EXT position.
In this case, an HD/VD signal is not out­put from the 12-pin multi-connector.

8 Trigger polarity selector switch

This switch can select the polarity (nega­tive or positive) of a trigger pulse.

9 75 Ω termination selector switch
0 Selection DIP switch

Switches 1 to 4:

Selects the shutter speed.

Switch 5: Selects the frame or field

integration.

Switches 6 to 8:

Selects the normal shutter,
external trigger shutter, and
restart/reset.

A GAIN switch

A: Outputs a fixed-level video signal ac-

cording to the brightness of a sub-

ject. (Variable range: 0 to 18 dB)
F: Fixed gain 0 dB
M: Variable gain (Manual)
M (during factory setting):

Adjusted so that all XC-ST70/70CEs

are the same in sensitivity (set by

Sony’s standard value) according to

the deviation in sensitivity of CCD.

Valid when multiple XC-ST70/70CEs

are used for an identical subject.

B Volume control switch

This switch can be changed in the range
of 0 to 18 dB when the GAIN switch is set
to “M”.
During factory setting, this switch is ad­justed to the fixed sensitivity for a stan­dard subject.

PHASE CONDITIONS OF EXTERNAL
SYNCHRONIZATION

External synchronization for each mode

• For normal video/normal shutter

Continuous HD/VD signal (should conform to EIA and CCIR frequencies in the timing shown in the figure below.)

• For Restart Reset (RR)/external trigger shutter

Continuous HD signal. The phase between VD (reset) and HD signals is as specified in the figure belo w in any
timing.

Phase conditions

The phase relation between external input HD and VD signals should be set as shown below with respect to the
specified center phase.

Note

: The synchronized VD signals are delayed for 1H at HD/VD external synchronization mode, while

there is no VD signal delay at VS external synchronization mode.

ELECTRONIC SHUTTER

Two types of electronic shutter are provided “normal shutter and external trigger shutter”.
The electronic shutter speed and type can be set using the DIP switch on the rear panel.

DIP switch on the rear panel

Normal shutter

This mode provides continuous video output with the electronic shutter selected by switches to clearly capture a
high-speed moving object.

Setting of normal shutter speed

XC-ST70/70CE

ELECTRONIC SHUTTER

External trigger shutter

These modes are used to capture one image (one field) per trigger pulse.
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, an internal video signal is output from a trigger pulse after a certain period of time.
Video sync is always fixed with odd field for XC-ST70 and even field for XC-ST70CE.

*

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

• 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-ST70)

120 µsec (XC-ST70CE)
