1. General

The CV-M9CL is a digital 3 CCD progressive scanned RGB color camera. It provides an upgraded
path from the CV-M90, adding higher resolution and Camera Link output.
It is based on a 1/3” image format, making it optically compatible with CV-M90 and CV-M91.
The compact 3 CCD C-mount prism unit is designed for high color quality, and combined with a
color shading correction, it allows use of a wide range of C-mount lenses.
30 full RGB frames can be read out as 3 x 8 bit via a base Camera Link connection, or 3 X 10 bit
in a medium Camera Link configuration. Functions like partial scanning and vertical binning
allows higher frame rates.

6. Functions and Operations

6.1. Basic functions

A 16-bit processor controls all functions in the CV-M9CL camera. The CCD sensor output is
normalized in preamplifiers. The signals are then digitized to 12 bits. Digital gain control and
look-up tables can do signal processing in 12 bits before it is truncated to a 10 or 8 bit camera
link signal.

6.1.1. Dynamic shading correction

The CV-M9CL camera has a digital shading correction circuit, which can compensate for prism
chromatic shading, for lens vignetting and for CCD shading. It makes the choice of lenses wider.
The camera with a given lens and a given f-number is looking on a homogeneous white scene.
A horizontal profile of the shading in 128 points is made for the 3 colors.
A vertical profile of the shading in 96 points is
made for the 3 colors.
The result is stored as gain difference from the
image centre.
Data from this h and v profile is used to adjust
the R, B and G gain depending of the H and V
position. The resulting image is then
compensated for shading caused by the lens,
prism and CCD.
The lens used is a Fujinon 15mm F2.2.
The iris is set to F5.6.
With the camera control tool it is possible to
customize the correction for a given set-up, and
store the corrections in a file. Refer to chapter 6.5.1.

Fig. 10. Shading correction.

Note: Lens requirements.

To obtain the best possible image, it is recommended to use lenses designed for 1/3” 3 CCD
cameras. The shading depends of the focal length and the iris setting. Avoid wide-angle lenses,
and do not use an iris setting fully open.

6.1.2. Knee function

The internal video signal is 12 bit, and only 8 or 10 bit is output. By help of the look-up table
function it is possible to compress or expand the video signal to change the dynamic range. It
can be done individually for R, G and B with the knee function.
The Knee function is given by 2 sets of parameters. Knee point and slope. These 2 sets of data
determine how the output would be with reference to the input data. This conversion is done by
the hardware (FPGA) doing calculations using the knee data.
The normal transfer function is with a slope 1:1. From a given point and up, the slope can be
changed. This point is the knee point parameter, and its range is from 0 to 1023 referring to the
video output. Factory setting is 890.

The new slope can be set from 1:0 to 1:2.
A slope 1:0 is a clipper function, which
will limit the output signal. A slope 1:2
will function as a 2 times contrast
expanding function.
The slope parameter range is from 0 to

4095.
0 is slope 1:0.
2048 is slope 1:1.

6.3. Input/Output of Timing Signals

For settings, please refer to chapter “7. Configuring the Camera”

6.3.1. Input of external trigger

Input of external trigger signal can be via Camera Link (TI=0). Factory setting. Or as TTL on the
12 pin connector pin 10. (TI=1). Here it should be 4.0 Vp-p ±2.0 V from a 75 Ω source. The
trigger input signal can be 75 Ω terminated. Factory setting is TTL. For 75 Ω termination
SW301.2 should be ON.

6.3.2. Output of EEN (XEEN)

The Exposure Enable signal EEN indicate that the accumulation is ongoing. It can be used for
controlling a strobe flash. The XEEN signal is found on the 12 pin connector pin 9. It is 4.0 Vp-p
from a 75 Ω source. The EEN signal is also found in Camera Link.

CV-M9 CL

6.4. Operation Modes

This camera can operate in 5 primary modes.

1. TR=0 Con Normal continuous Mode Pre-selected exposure.

2. TR=1 EPS Edge Pre-select Mode Pre-selected exposure.

3. TR=2 PWC Pulse Width Control Mode Pulse width controlled exposure.

4. TR=3 SG Sensor Gate Control Strobe illum. exp. with delayed read out

5. TR=4 RCT Reset Continuous Trigger Pre-selected exposure.

The triggered accumulation in EPS, PWC and RTC mode can be LVAL synchronous or LVAL a­synchronous.

In LVAL synchronous accumulation, a new exposure can be started while the previous frame is
read out. The new exposure should not be finished before the frame is read out. FVAL shall be
low for >2 LVAL. The maximum frame rate in trigger modes can then be close to the frame rate
in continuous mode.
The minimum trigger interval should be longer than (1 FVAL+2 LVAL).
To avoid <1L time jitter in LVAL synchronous mode, it is recommended to synchronize the trigger
to LVAL.

In LVAL a-synchronous accumulation, a new trigger must not be applied before the previous
frame is read out. (FVAL is low).
The minimum trigger interval should be longer than (exposure time + 1 FVAL+3 LVAL).

Refer to chapter 6.4.1. and 6.4.2. for accumulation details.

Refer to chapter “7. Configuring the Camera” for details in mode settings.

6.4.1. LVAL synchronous accumulation

With LS=0, the accumulation will start synchronously with LVAL. The trigger pulse should be
longer than 2 LVAL intervals, and the accumulation will then start at the first LVAL after the
trigger leading edge. The exposure start delay will be up to 1 line. (42.07 µsec.).
In EPS mode the exposure stops 0.5 L after the selected shutter time, (in number of LVAL).
In PWC mode the exposure stops 0.5 L after the first LVAL after the trigger trailing edge. It
results in up to 1 LVAL jitter.

In trigger modes with LVAL synchronous accumulation, a new exposure can be started while the
previous frame is read out. The new exposure should not finish before the frame is read out.
FVAL shall be low for >2 LVAL. The maximum frame rate in trigger modes can then be close to
the frame rate in continuous mode.

Minimum trigger interval

≥

(1 FVAL + 2 LVAL).

Important notes on using this mode.

In LVAL synchronous PWC mode exposure jitter up to 1 LVAL can be the result, if the trigger
trailing edge is not synchronized to LVAL.

CV-M9 CL

6.4.2. LVAL a-synchronous accumulation

With LS=1, the accumulation will start immediately after the trigger leading edge.
The exposure start delay is 9.7 µsec.
In EPS mode the exposure stops 0.5 L after the selected shutter time, (in number of LVAL).
In PWC mode the exposure stops 0.5 L after the trigger trailing edge.

A new trigger must not be applied before the previous frame is read out. (FVAL is low).

Minimum trigger interval

≥

( exposure time + 1 FVAL + 3 LVAL).

Important notes on using this mode.

In LVAL a-synchronous PWC mode there is no exposure jitter.

6.4.4. Edge Pre-select Trigger Mode

An external trigger pulse initiates the capture, and the exposure time (accumulation time) is the
fixed shutter speed set by SH or PE. The accumulation can be LVAL synchronous or LVAL a­synchronous.
The resulting video signal will start to be read out after the selected shutter time.

6.4.5. Pulse Width Control Trigger Mode

In this mode the accumulation time is equal the trigger pulse width. Here it is possible to have
long time exposure. The maximum recommended time is <2 seconds.
The accumulation can be LVAL synchronous or LVAL a-synchronous.
The resulting video signal will start to be read out after the trigger rising edge.

For timing details, refer to fig. 13. through fig. 20. and fig. 26.

To use this mode:

CV-M9 CL

6.4.6. Reset Continuous Trigger mode

The RCT mode is in principle the same as normal continuous mode. The difference is that an
external trigger pulse will immediately stop the video read out and reset and restart the vertical
timing. After a fast dump read out (198 L = 8.33ms), a new triggered exposure is started and
read out as normal. The fast dump read out is performed with a speed 4 times faster as normal.
If no further trigger pulses are applied, the camera will continue in normal mode. This fast dump
read out has the same effect as “smearless read out”. Smear over highlighted areas are reduced
for the triggered frame.
The reset continuous trigger mode makes it possible to use a lens with video controlled iris
together with a triggered exposure.

For timing details, refer to fig. 13. through fig. 20. and fig. 27.

To use this mode:
Set function: Trigger mode to “Reset continuous trigger”. TR=4
Scanning SC=0 through 3
Vertical binning BI=0, BI=1
Shutter mode normal, programmable or auto SM=0 through 2
Shutter speed SH=0 through 11
Programmable exp. PE=0 through 791
Accumulation LVAL synch. or a-synch. LS=0, LS=1
Other functions and settings
Input: Ext. trigger. Camera Link or 12 HiRose TI=0, TI=1

Important notes on using this mode

Trigger pulse >2 LVAL to <1 FVAL

To avoid ≤ 1 LVAL jitter in synch. accum, synchronize the trigger to LVAL.
Minimum trigger interval ≥ (exposure time + 1 FVAL + 2 LVAL + 198 LVAL).

6.4.7. Sensor Gate Control

This function is for applications with strobe flash illuminations or long time accumulations up to
several frames. The external Sensor Gate control signal will disable the internal SG pulse so the
accumulation will continue during the next frame. As long as the sensor gate control signal is
low, the accumulation will continue. The resulting video is read out after the first FVAL (or SG),
following the trailing edge of the Sensor Gate Control signal. Fig. 28.
To disable the internal SG pulse, the sensor gate control signal should be low 2 µs before.
Fig. 29. shows the sensor gate signal setup time and hold time. It is inside the first line after
FVAL goes low.

For timing details, refer to fig. 13. through fig. 20. and fig. 28. - 29.

6.5. Other Functions.

Scanning. SC=0 through 3.

The CCD scanning format can be selected between full or partial scanning. With partial scanning
only the vertical central part of the CCD sensor is read out with a higher frame rate. The partial
scan is done by a fast dump read out of the lines in the vertical ccd register down to the top of
the partial image. The partial part of the image is read out with normal speed. The lines below
the partial image is read out and dumped with a high speed. With partial scan the shutter speed
is limited to be shorter than the frame read out time. There is no limitation in PWC mode.

Bit allocation. BA=0, BA=1.

The video output in Camera Link can be
selected to be 10 or 8 bits (BA=0, BA=1). For
8 bits only the 8 most significant bits are
output.
The relations between CCD signal output,
normal analog video signal and the digital
video signal are shown.

Binning. BI=0 through BI=1.

Binning mode is a function where the signal charge from 2 or more adjacent pixels are added
together and read out as one pixel. A resulting full frame with lower spatial resolution can be
read out with a higher rate, and higher sensitivity. The CV-M9CL has vertical binning 2:1.
Vertical binning is done by adding the pixel charge from adjacent lines together in the horizontal
ccd register. It is done by multiple shift pulses to the vertical ccd register.
Lowest shutter speed is reduced to be shorter than the frame read out time. There are no
limitations in PWC mode.

Smearless readout. SL=1.

This function will reduce the unwanted smear signal from a highlighted scene when a short
exposure time is used. It works in all trigger modes, but a dummy readout is performed before
the active accumulation is started. It will remove the smear above the highlighted parts in the
image, but there is still smear left below highlighted areas.
The trigger leading edge will start the dummy readout. It takes 198 LVAL (8.33ms) before the
exposure starts. The exposure stops and the resulting video signal is read out. This mode will
operate with full and partial scanning and with all binning modes.

Color bar. CBAR=0, CBAR=1.

The command CBAR=1 insert a standard color test bar on the output image, so it can be used for
calibration. For color bar specifications refer to chapter 6.1.3.

Shutter mode. SM=0, SM=1 and SM=2. SH=0 through SH=11 and PE=2 through PE=791.

With SM=0 this function selects the shutter from the 12 fixed steps (SH). With SM=1 from
programmable in 789 steps (PE). SM=2 is for individual programmable exposure of red, green and
blue. PER, PEG and PEB =2 through =791. It allows a wide range of manual color balance
adjusting.

RCT FVAL type. RF=0, RF=1.

This command selects the FVAL type in RCT mode. Refer to chapter 6.4.6. Reset Continuous
Trigger mode.

Trigger input select. TI=0, TI=1.

This function selects the trigger input to be through Camera Link (TI=0), or as TTL through the
12 pin Hirose connector (TI=1).

Trigger polarity. TP=0, TP=1.

The active trigger polarity is normal low (TP=0). It can be invert it to active high (TP=1).

Note: With TP=1 and TI=1, the first trigger pulse after power up will be ignored.

White balance. WB=0 through, WB=4.

By adjusting the R, G and B gain depending of the scene illumination color temperature it is
possible to have correct color balance in the video output. A white scene will be shown as a
white image. This white balance can be done in different ways.
WB=0 is for manual/one push white balance. In manual, the white balance can be changed by
the gain settings. The one push white balance function is also active here. WB=1 is continuous
white balance. WB=2, WB=3 and WB=4 are fixed values 3200K, 4600K and 5600K. Factory
adjusted to 3200K.

One push white balance. AW=0

If the command WB=0 is received, an automatic white balance is performed once. The result of
this function can be requested by the command AWRS?

Knee function. KN=0, KN=1.

If KN=1 is received the knee function is enabled.
With the knee functions is possible to change the relation between CCD signal and the resulting
output video signal. With the function disabled, the transfer slope is 1:1.
The level where the slope should be changed is set with the knee point settings. Its range is from
0 to 1023 related to the video output. Factory setting is 890. (100%).
From the knee point and up, the slope can be changed from the normal 1:1. The slope
parameter range is from 0 to 4095, where 0 is slope 1:0, 2048 is slope 1:1, and 4095 is slope 1:2.
The slope range is from 0 to 2, where 0 is completely limitation (or clipping) and 2 is contrast
expanding. Factory setting is 800. The slope is then 800/2048 or 0.39

6.5.1. Customized shading correction.

From factory, the CV-M9CL camera is delivered with a shading correction adjusted to work with
homogeny lightening coming from a DC regulated halogen lamp at 3200K and a certain Fujinon
lens. This shading data stored in the factory area is also used for the 3 user areas. For other
fixed illumination and for another fixed lens in a specific setup, it makes sense to make a
temporary customized shading calibration.

When such calibration is done, it will be used in the camera until next power up. Here the old
factory shading data will be called and used.

With the Camera Control Tool it is possible to store the customized shading corrections in a file.
This file can then be loaded into the camera after next power up.

To make a customized shading calibration it is most important to avoid flickering of the
lightening like AC powered light and also reflections should be avoided – such effects will
interfere with the calibration. Apart from that the light temperature and the light density over
the area of interest should be exactly as for the real setup.

The camera setting has to be as follows:

• Master gain 0dB

• Individual gain 0dB

• Shutter off

• Trigger modes off - use Normal mode

• Binning and Partial scan off

• Use 10 bit output mode

• Shading corrector off

Continue with the following:

• Set up the illumination, as it should be in the real application.

• Place a perfectly flat white object (piece of paper) at the actual scene. No reflections

must be visible.

• Adjust the lens iris and focus to the level, which should be used in the real application.

• Make sure that the signal level at scene centre equals around 800LSB.

• When the above is okay then perform an Auto White Balance [command: WB=1].

• Be sure that no part of the image is saturated.

• Now the camera is ready to perform an Auto Shading Correction: [Command: ATSH=0].

• If the shading correction is successful, the camera will respond COMPLETE.

• Turn the shading on and off some times to verify the effect of the shading correction.

[Command: SDM=1 and SDM=0].

• The new customized shading corrections data will be used for all user areas until factory

area is called, or until next power up, where the factory shading corrections are called.

• With the camera control tool (version 1.2 or later), the customized shading data can be

stored in a file. For later use, this file can then be loaded into the camera.

This command will load previous stored settings to the camera. 3 user settings can be stored in
the camera EEPROM. 1 factory setting is also stored in the camera. The settings stored in the
last used user area is used as default settings at power up.

Save Settings. SA.

This command will store the actual camera settings to 1 of 3 user areas in the camera EEPROM.
Factory settings can not be changed.

EEPROM Area. EA.

If received, the camera will return the last used user area number.

8. Camera Control Tool for CV-M9CL

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.

8.1. Control Tool Windows

Fig. 35. Camera control tool windows.

- 32 -

CV-M9 CL

8.2. Camera Control Tool Interface

The Camera Control Tool Software is based on a main Tool Bar and a number of
associated Tool Windows. Each button in the Tool Bar pops up a separate Tool
Window when pressed. The layout of the program can be adjusted by arranging
the windows the way it is preferred. The program will store this information
and recreate this layout, when the program is restarted.
All Camera Control Tools have a Communication Window and an About Window. The other
window(s) contains camera control commands.

The About window

The about window contains a picture of the camera and
information about the version of the program, Internet
connection to JAI A/S and access to the help documents.
The List box that contains the help documents will list all
files, which have the extension .pdf and that are found in the
program (default) folder

C:\Program Files\JAI A-S\’Control Tool Name’

It is possible to download updated operation manuals from
the jai website:

http://www.jai.com/camera/manuals.asp/sprog=uk

An updated manual can be saved in the folder address
mentioned above and it will automatically be included in the
list of help files.
For newer camera models the About Window also shows
Model Name, camera ID and User ID. It is possible to edit and
save free text in User ID.
At the bottom of the windows (all windows but the
Communication Window is a coloured bar. The bar is green
when the Camera Control Tool is connected to a camera and
the camera is turned on.
The bar is red when the Camera Control Tool is not
connected to a camera or when the camera is turned off.

The Communication Window

The Communication Window is used to connect the Camera
Control Tool with the JAI camera. Depending of camera there
are 2 possible ways to communicate with a JAI camera.
RS-232:
Select the communication port, where the serial cable is
connected from the list box in the ‘Communication Port’
field, or click the ‘Auto’ button to search for a camera on
communication port 1 to 16. The camera control program
automatically sends a camera request on every
communication port. The user is prompted to use a
communication port if a camera answers the request.
RS-232 and Camera Link:
The Communication Window looks a bit different when it is
possible to communicate with the camera using Camera Link
and RS-232 com port. The Communication area contains 2 list boxes now.

- 33 -

CV-M9 CL

RS-232 communication:

1. Select ’COM-ports’ from the ’CL Manufacturer/COM-ports’ list Box.

2. Select the communication port, where the serial cable is connected to
the camera from the ’Serial Port’ list box or click the ‘Auto’ button to
search for a camera on communication port 1 to 16.

The Serial Port list box and the Auto search button are only active when COM-ports is selected.

Camera Link communication:
The ’CL Manufacturer/COM-ports’ list box also contains DLL
file names (or frame grabber names) for all Camera Link
frame grabbers that are installed in the pc. This is done by
using a DLL file called "clserial.dll" to upload all frame
grabber DLLs that are found in the pc.
Just select the option for the frame grabber that is installed in the pc.

Auto search
Click the auto button to search for a camera on communication port 1 to 16. The camera control
program automatically sends camera request on every communication port. The user is
prompted to use a communication port if a camera answers the request.
This button is only used for RS-232 communication.

Off/On-line mode
The Camera Control Tool Application can run Offline (without a camera attached)
and all functions are fully functional in offline mode.
Off line mode is indicated in The Communication Window, where a status field with
graphic and text indicates the on/off-line status.
Changing the selected communication port (from the communication window)
changes the online/off-line status. If a camera is found on the selected communication port the
application runs online otherwise offline.

Changing the settings in the application will automatically update the camera settings when the
application is online.
If the application looses connection with the camera it will automatically go to offline mode and
it is indicated in the communication window.

Synchronize program and camera
The Camera Control software has the ability to synchronize either the camera or
the program. Click Synchronize camera to write all settings from the program to
the camera or click the Synchronize program to load all settings from the camera
to the program.

Files

When clicking the Write to File or Read from File button, the user is prompted for a file using a
standard file dialog. New files are created if they do not already exist.
Files for camera settings have the extension cam. Information about the communication port is
not stored in the files. All settings are automatically sent to the camera when a file has been
loaded (if the camera is online).

- 34 -

CV-M9 CL

Factory and User Settings

Use the Store button to store the current camera settings into the user settings area in EEPROM.
Current camera settings are not saved when the camera is turned off. To save current camera
settings you have to save them on the available user areas.
Use the Load button to restore previously saved camera settings from either the Factory or the
User EEPROM area.

Write All Camera Data to File.
Click the “Write Camera Data” button to save all camera settings into a
text file. The information that can be saved is:
Model Name, Camera ID, User ID, Firmware Version, Current Settings,
Factory Settings and the available User Areas.
The file is formatted as shown in the picture below:

EEPROM Current Area.
Click the ‘Get Area’ button to read the power up settings area number.

8.3. Using the Camera Control Tool

Here is some practical information about the Camera Control Tool:

1. The Camera Control Tool bar is always on top of other windows.

2. When you minimize the Camera Control Tool bar all open windows will close.

3. It is possible to work with the Camera Control Tool when the camera is online and when
the camera is offline.

4. The newer JAI cameras always start up with the last used user area (but for some old
models it will start up with the last saved user area.)

5. The Camera Control Tool saves the last used settings (not the user area), which don’t
have to be the same as for the last saved user area.

6. The setup file ’CameraName.ini’ stores all information about camera settings. When the
program is started the last settings for the program are loaded from the file
’CameraName.ini’

7. When you turn on the camera and the Camera Control Tool, it is possible that the Camera
Control Tool does not show the actual camera settings (see 4. and 5.).

a. To obtain the camera settings click “Synchronize Program”.
b. To send the settings that are saved in the Camera Control Tool (last used settings)

to the camera click “Synchronize Camera”.

c. To see which area the camera has started up in click “Get Area”.
