1. General
The CV-M91 3 CCD RGB color camera is a new updated version of CV-M90. The prism is improved,
and new CCD sensors are used. The new CCD sensor has 5 dB higher sensitivity, 15 dB lower
smear and 4 dB higher dynamic range. Now there are Y/C output and input for composite sync.
Pulse width control shutter is now fully implemented.
CV-M91 is a 3 CCD RGB color camera designed for machine vision and image processing
applications where excellent resolution, high quality color reproduction are required.
The compact 3 CCD C-mount optical prism unit is designed for high color quality, and it allows
use of a wide range of C-mount lenses.
CV-M91P is the CCIR PAL version, and CV-M91N is the EIA NTSC version.

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.

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.

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.

7.5. Camera Control Tool for CV-M91
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.
