6. Functions and Operations

The different camera modes and functions can be set by switches and jumpers. Some functions like RGB setup and white clip can only be changed via RS-232C. Function names within “ “ are names used in camera control tool.

6.1. Input/Output of Signals

6.1.1. Input/output of HD/VD

In the default setting the camera will accept external HD/VD signals on pin 6 and 7 of the 12 pin Hirose connector. If external HD/VD is applied, the camera will synchronize to it. If no external sync signals are applied, the camera will operate with its internal x-tal controlled sync. The time requirements to the relation between VD and HD are shown in fig. 10. The input is TTL level as factory setting. It can be 75 Ohm terminated by an internal switch. Internal HD/VD signals can be output on pin 6 and 7 by internal jumper settings. The output is TTL level from a 75-Ohm source. In trigger modes a VD pulse will only be output after an external trigger pulse. Refer to “7. Configuring the Camera.”

To use this mode: Set function on PK8407: JP305 s, JP306 o for ext. VD input. Factory default. JP308 s, JP309 o for ext. HD input. Factory default. SW301-1(HD), SW301-2(VD) to OFF for TTL level. Factory default. SW301-1(HD), SW301-2(VD) to ON for 75 Ω termination JP305 o, JP306 s for int. VD output JP308 o, JP309 s for int. HD output Input/output: Ext. VD in or int. VD out on pin 7 on 12-pin connector. Ext. HD in or int. HD out on pin 6 on 12-pin connector.

If only a composite VS signal is available, it is possible to enable an internal sync separator to separate HD and VD from the composite signal.

To use this mode: Set jumper on PK8407: JP312 s, JP313 o, JP315 o, JP318 s, JP319 o for HD/VD input. Default. JP312 o, JP313 s, JP315 s, JP318 o JP319 s for comp. VS input. Input Ext. VS (1Vpp ±30%) on pin 7 on 12 pin connector.

Important notes on using this mode.

• External sync system should follow the camera scanning system

• Requirements to HD/VD phase is shown in fig. 10

6.2.3. Pulse Width Control Mode

The exposure will start at the first HD after the trigger leading edge, and it stops between the first and second HD after the trigger trailing edge. An EEN pulse indicate the accumulation time, and a WEN pulse indicates that the resulting video is read out. Refer to “7. Configuring the Camera.”

To use this mode: Set function: Trigger mode to “Pulse width control”. SW 1-4 to ON On PK8407: JP301 open, JP302 open, JP311 open. Accumulation to “Field”. SW 301-4 on PK8407 to OFF Scanning to “Non-interlaced”. SW 1-5 to ON Shutter Speed to “1/10,000”. SW 1-1 through 1-3 to ON Other functions Input: Ext. trigger to pin 5 on 6-pin connector. Ext HD to pin 6 on 12 pin connector. (If used).

Important notes on using this mode.

• The duration of the trigger can be >1H to <900H. (>64 µsec. to <60msec.)

• To avoid 1H jitter it is recommended to synchronize the trigger to HD. (See fig. 11.)

• A new trigger can not be applied before WEN is high

CV-M91

6.2.4. Start Stop Mode

The exposure time is controlled by the interval between the ext. trigger and the ext. VD signal. The exposure starts at the first HD pulse after the falling edge of the ext. trigger, and stops 14.5 H after the falling edge of the VD pulse. It means that the trigger pulse must be applied after the external VD pulse, for exposures less than 14.5 H. The range can be between 1/77 to 1/10,000. The Start/Stop mode is a continuous mode where the VD signal must be given continuously. It is not possible to input external VD randomly. The difference between interlaced frame and field accumulation can be explained as follow. Both modes have 2 fields output in an interlaced frame. With frame accumulation, the contents in the ODD and EVEN sync fields will come from sensing field 1 and 2 on the CCD sensor. With field accumulation both ODD and EVEN sync fields will contain the signal from sensing field 1 and 2 added together. Non-interlaced field accumulation needs only 1 trigger pulse for each field. Refer to “7. Configuring the Camera.” To use this mode: Set function: Trigger mode to “Start Stop”. SW 1-4 to OFF On PK8407: JP301 short, JP302 open, JP311 short. Accumulation to “Field” or “Frame”. SW 301-4 to OFF or ON Scanning to “Non-interlaced” or “Interlaced”. SW 1-5 to ON or OFF Shutter Speed to “1/10,000 ”. SW 1-1 through 1-3 to ON Other functions Input: Ext. trigger to pin 5 on 6-pin connector. Ext. VD to pin 7 on 12-pin connector (Ext. HD to pin 6 on 12-pin connector). Option

Important notes on using this mode.

6.2.5. Long time integration

The exposure time is the interval between 2 ext. VD pulses sent to the VD input. (Pin No. 7 of the 12-pin connector). The exposure starts after input of the first ext. VD pulse, and ends after the next input of the next ext. VD pulse, which again starts a new exposure. The long time exposure is a continuous process where each external VD will synchronize the camera, stop the exposure, start a new exposure and read out the previous accumulated signal. The exposure time can be selected in intervals of complete vertical timing periods. (Interlaced frame: EIA 525H and CCIR 625H. Non-interlaced field EIA 262H and CCIR 312H). Refer to “7. Configuring the Camera.”

To use this mode: Set function: Trigger mode to “Long Time integrationl”. SW 1-4 to OFF On PK8407: JP301 open, JP302 short, JP311 short. Accumulation to “Field” or “Frame”. SW 301-4 to OFF or ON Scanning to “Non-interlaced” or “Interlaced”. SW 1-5 to ON or OFF Shutter Speed to “OFF ”. SW 1-1 through 1-3 to OFF Other functions Input: Ext. VD to pin 7 on 12-pin connector (Ext. HD to pin 7 on 12-pin connector). Option

Important notes on using this mode.

• The exposure range is from 1 field to ∞. However it is recommended not to use exposure over 2 seconds due visible dark current signals.

• The ext. VD signal should follow the camera sync system and interlace setting.

• Requirements to HD/VD phase is shown in fig. 10.

7.5. Camera Control Tool for CV-M91

From www.jai.com Camera Control Tool for Windows 98/NT/2000 can be downloaded. The control tool contains a camera control program and tools for making your own program. For the integrator and experienced user, the Camera Control Tool is much more than a program with a window interface. It also provides an easy and efficient ActiveX interface built for MS Windows 98, ME, NT and 2000. The OCX interface has the ability to connect to the camera using the serial interface of the PC by reading and writing properties for the camera. This integration requires simple programming skills within Visual Basic, Visual C++ or similar languages in a Microsoft Windows environment. Below the different windows are shown.

10. Appendix

10.1. Precautions

Personnel not trained in dealing with similar electronic devices should not service this camera. The camera contains components sensitive to electrostatic discharge. The handling of these devices should follow the requirements of electrostatic sensitive components. Do not attempt to disassemble this camera. Do not expose this camera to rain or moisture. Do not face this camera towards the sun, extreme bright light or light reflecting objects. When this camera is not in use, put the supplied lens cap on the lens mount. Handle this camera with the maximum care. Operate this camera only from the type of power source indicated on the camera. Power off the camera during any modification such as changes of jumper and switch setting.

10.2. Typical CCD Characteristics

The following effects may be observed on the video monitor screen. They do not indicate any fault of the CCD camera, but do associate with typical CCD characteristics.

V. Smear

Due to an excessive bright object such as electric lighting, sun or strong reflection, vertical smear may be visible on the video monitor screen. This phenomenon is related to the characteristics of the Interline Transfer System employed in the CCD.

V. Aliasing

When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged image on the monitor may appear.

Blemishes

Some pixel defects can occur, but this does not have en effect on the practical operation.

Patterned Noise

When the CCD camera captures a dark object at high temperature or is used for long time integration, fixed pattern noise (shown as white dots) may appear on the video monitor screen.
