Component / OEM

OUTLINE
The XC-ST50/ST50CE and XC-ST30/ST30CE incorporate the latest CCD and signal processing technologies into a compact black and white camera module. A new external trigger design allows the electronic shutter speed to be freely specified by the width of an external trigger pulse or by a switch setting on the rear panel of the camera. These cameras are also user-friendly, with all switch settings located on the rear panel. Moreover, the XC-ST50/ST50CE 1/2 type CCD and XC-ST30/ST30CE 1/3 type CCD models have the exact same dimensions, simplifying space requirements and making it easy to interchange them if necessary. These features, along with high picture quality and high shock and vibration tolerance make the XC-ST50/ST50CE and XC-ST30/ST30CE cameras ideal for demanding machine vision applications.

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 XCST50/50CE 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.

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.

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.

Restart Reset (R.R) 1 1

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.

Timing and conditions

Example 1 of Long exposure

EXT HD

Continuous signal: 15.734 kHz (XC-ST50/ST30), 15.625 kHz (XC-ST50CE/30CE) Allowable frequency value 1%

EXT VD

VD interval(T): 262.5H or more (XC-ST50/ST30), 312.5H or more (XC-ST50CE/30CE) and 1 second or less (Recommended) Four or more VD pulses are required. T T T
Exposure time for Odd field Exposure time for Even field

Video output

Odd image Invalid image Even image Valid frame image
Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside.
Example 2 of long exposure
VD interval(T): 262.5H or more (XC-ST50/ST30), 312.5H or more (XC-ST50CE/30CE) and 1 second or less (Recommended) Four or more VD pulses are required. T 1/60 second 1/60 second
Odd image Invalid image Even image

Valid frame image

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.
<Timing chart by restart/reset>
VD: XC-ST50/ST30 (1/60 sec), XC-ST50CE/30CE (1/50 sec) Four or more VD pulses are required.

Strobe light

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).

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. 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 external VD, there may be a delay of 1VD in the output. The period of uncertainty is when the falling edge of VD is between 65 s before or 10 s after the falling edge of the trigger. 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.

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. Be sure to input an external VD signal between 10 s and 100 ms from the falling edge of a trigger pulse (as shown by 1 and 2 in 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. When the external trigger shutter mode changes into the normal operation mode, one WEN signal is output.

The normal operation state is engaged when the high period exceeds 1/3 sec. After that, 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 input inhibition area. During the trigger inhibit period, an input trigger may be missed. An internal VD signal is output by setting the INT/EXT switch on the rear panel to INT. During external trigger shutter operation, an image is output when an internal VD signal falls after a trigger pulse falls (as shown by 1 and 2 in the figure). However, if the time (T in the figure) between the falling edges of a trigger pulse and internal VD signal is under 10 s, an image is output when the internal VD signal or the next internal VD signal falls (as shown by 3 in the figure). (In this case, an image is output when the next internal VD signal falls.) An image and WEN signal are always output together. For more details, refer to the WEN signal. (The falling edge of an internal VD signal is the same in phase as the beginning of an equalizing pulse in a SYNC V area.) When the external trigger shutter mode changes into the normal operation mode, one WEN signal is output.
