1. General
This manual will cover the following 4 cameras: CV-M4+/CV-M4+CL and CV-M7+/CV-M7+CL.
The revision B cameras are updated with a new function, Restart Continuous Trigger mode
(RCT). The trigger can be H a-synchronous or H synchronous. Binning is now only vertical.
The cameras are based on progressive scan 2/3” CCD megapixel interline transfer sensors.

The color cameras use a RGB primary color filter CCD sensor (Bayer color filter). The video
output is a single data stream with the RGB signals in sequence. The RGB color decoding should
be done in the host PC.
The cameras are designed for automated imaging applications, featuring high resolution and high
speed within a uniform and compact housing.
The high-speed shutter function, asynchronous random trigger mode and partial scan mode
allows the camera to capture high quality images of fast moving objects with a high frame rate.
It is suitable for industrial applications such as on-line inspection and measurement.
Thanks to the EIA-644 (LVDS) digital interface, crisp and clear images are achieved.

6. Functions and Operations
6.1. Basic functions
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. (SC=1 1/50. SC=2 1/100. SC=3 1/200). In
PWC mode TR=2, there is no limitation.
A minor signal distortion can be expected below highlighted areas, (saturated areas). It is caused
by limitation in the vertical ccd register transfer efficiency at high speed.
Lines shown in partial scans are: 1/2 PS 512 lines. 1/4 PS 256 lines. 1/8 PS 128 lines.

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-M4
pixel charge from 2 adjacent lines are added together in the horizontal ccd register. It is done
by double pulses to the vertical ccd register. Lowest shutter speed is 1/50. In binning mode H is
43.3 µ sec. Binning will only work for the monochrome cameras CV-M4

Multiple exposure is a function which allows several exposures with a short interval. The
exposures are all placed in the same frame. This function is useful for studies of high speed
events.
The trigger leading edge will start the first exposure (edge pre select). When it is finished, the
resulting charge is read out in the stopped vertical ccd register. With additional trigger pulses on
the multi exposure input, new exposures can be done. The charge from each is added on top of
the first charge in the stopped vertical ccd register. Up to 6 exposures can be done with multi
exposure. The trigger trailing edge will start the vertical ccd registers, and the video signal will
be read out. Fig. 13 shows the timing details.

CV-M4+/M4+CL, CV-M7+/M7+CL
Color versions CV-M7
These color cameras are identical to the monochrome cameras. Only the CCD sensor is changed
to a RGB primary color type. Here the color mosaic lay out is shown in fig. 13. left. This lay out
is known as a Bayer filter. Based on the knowledge to this mosaic, a full RGB signal can be
constructed by some calculations in the host Pc as shown in the following example.
For the precise position of the R, G and B pixels in the mosaic, please refer to the table below.
The output signal from the CCD sensor is not a complete RGB signal. Green values are missing
where the blue and red pixels are placed. Blue values are missing where green and red pixels are
placed. Red values are missing where the green and blue pixels are placed.
To have a complete RGB signal, values for the missing pixels can be constructed based on values
of the adjacent pixels with the corresponding color.
+
and CV-M7+CL
From the color mosaic lay out it can be seen that signals from 3 adjacent lines are needed for
the calculation of some of the missing pixel values. It is why binning can not be used for M7+.
The values for the missing blue (b) and red (r) pixels are calculated in 3 different ways. Some
are based on adding the 4 diagonal placed pixels. The sum is then divided by 4. Other
calculations are done by adding the 2 values. The upper and lower (or the left and the right) are
added together, and the sum is divided by 2.
Missing green (g) pixels are all based on adding left + right + upper + lower and then divide the
sum by 4. Shown in fig. 14. right.

Restart Continuous Trigger mode. RCT.
The RCT mode makes it possible to use a lens with video controlled iris for intelligent traffic
surveillance applications, ITS. The camera is running continuously, and the iris is controlled from
the iris video output. When a trigger pulse is applied, the scanning is reset, the previous signal is
dumped with a fast dump read out, and the new triggered exposure is started. This fast dump
read out takes 133 H (5,23 msec. and it has the same effect as “smearless read out”. Smear over
highlighted areas are reduced for the triggered frame. In edge pre-select mode (TR=1), the RCT
mode (RC=1) can be activated. RCT cannot be selected by switch settings.

6.2. Output of Timing Signals
It is not possible to synchronize the camera from an external sync source except by extern
trigger. The camera will always run with its internal X-tal controlled timing.
The CV-M4
(EIA64), or with Camera Link interface.
To synchronize the video data transfer from the camera the following signals are available:
FEN Frame enable
LEN Line enable
PCLK Pixel clock
DVAL
EEN Exposure enable. (Low during active exposure).
See the full connector pin assignment for LVDS a Camera Link in chapter 5.2 and 5.3.

6.4. External Trigger Modes
This camera has 3 external asynchronous trigger modes, which can be set by RS-232C commands
or switches.
1. Edge Pre-select Mode. TR=1 Pre-selected exposure. (SM=0, SM=1)
2. Pulse Width Control Mode. TR=2 Pulse width controlled exposure.
3. Frame Delay read out mode. TR=3 Pre-select exp. Read out by trailing trig. edge.
The trigger can be H synchronous (HC=0) or H a-synchronous (HC=1). Refer to fig. 12.
In H synchronous mode, the accumulation will start at the first H (LEN) after the trigger leading
edge. In H a-synchronous mode the trigger leading edge will immediately reset the internal H,
(LEN). After a Xsub pulse the accumulation will start. Shown in fig. 19.
In edge pre-select mode the shutter time can be selected from the normal 10 fixed steps.
(SM=0). Or it can be selected from the 1056 steps programmable (SM=1).
Remark that H is 39.3 µsec. But 43.3 µsec. when vertical binnig is on.
Restart Continuous Trigger RCT mode (RC=1) can be activated in edge pre-select mode (TR=1).
(By RS-232C and CL only)
In pulse width control (PWC) mode the exposure time can be from 2H to ∞. Thermal noise and
dark current noise will increase by accumulation time, therefore the exposure time is not
recommended to exceed 2 seconds.
Vertical binnig mode (BI=1) can be used in all 3 modes. Only with full scan. (SC=0). Binning will
only work on M4
Partial scan (SC=0 through 3) can be used in all 3 modes. Only with binning off. (BI=0).
For all 3 modes smearless read out (SL=1) can be used. At the leading edge of the trigger pulse a
dump read out of the vertical ccd register is performed before the accumulation is started. It
takes 133 H. It means that the trigger pulse width in PWC and frame delay mode should be
>133H. (5.23 msec.)
For frame delay read out (TR=3) the multiple shutter function is available. (ML=1). It can also be
combined with smearless read out.

6.5. Edge Pre-select Mode
The trigger leading edge will start the exposure H synchronous or H a-synchronous (HC=0, HC=1).
The exposure stops and is read out after the shutter time selected. It can be the 10 steps in
normal or 1056 steps in programmable. SM=0 or SM=1. This mode will operate with full and
partial scanning and with V-binning (M4
combinations is not allowed.
In this mode the Restart Continuous Trigger mode (RC=1) can be activated. (By RS-232C and CL
only). The camera is then running continuously, and it can be reset and restarted by the trigger
pulse.
If smearless read out (SL=1) is used, the exposure starts with a delay 133H (5.23 msec.) after the
trigger. An EEN pulse will indicate the active accumulation time, and a FEN pulse indicates that
the resulting video is read out.
To use this mode:
Set function: Trigger mode “Edge Pre-select” TR = 1
Shutter mode “Normal” or “Programmable” SM=0, SM=1
“Shutter Speed” SH=0 through 9
“Programmable exposure” PE=0 through 1057
“H synchronous trigger” HC=0, HC=1
“Restart Continuous Trigger” RC=0, RC=1
“Smearless readout” SL=0, SL=1
Polarity and other functions
Input: Ext. trigger to LVDS/Camera Link or pin 10 on 12-pin connector.
Important notes on using this mode.
• The duration of the trigger should be >2H to <3V. (>72.64µsec to <120msec).
• The minimum trigger interval should be >(exposure time + 1 frame). A new trigger must
not be applied during the previous frame read out. (Before FEN is high).

7.6. Camera Control Tool for CV-M4+
From www.jai.com Camera Control Tool for Windows 98/NT/2000 can be downloaded.
The control tool contents a camera control program and tools for making your own program.
Below the different windows are shown.
Fig. 28. Camera control tool windows.
For the integrator and experienced user, the Camera Control Toll 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.

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.
Disclaimer
Increased dark current (white spots) over time in ExView sensors.
It is known that radiation damage increases the dark current of a CCD sensor. This is also true
for radiation arising from natural sources, also known as background radiation. These sources
include:
1. Terrestrial radiation from naturally occurring radioactive isotopes in the soil.
2. Cosmic radiation originating in outer space.
3. Naturally occurring radioactive isotopes in the body.
The ExView series of CCD sensors have greatly improved responsivity, especially in the Near IR
part of the spectrum. This greatly improved performance comes at the price of accelerated
degradation (increased dark current) due to natural background radiation. This degradation
effect is approximately 4 times as fast as in standard sensors, such as Hyper HAD sensors.
The degradation effect will manifest itself as in increasing non-uniformity of pixels when viewed
in the dark (white spots). This is a natural effect, and is not eligible for warranty
replacement/repair of the CCD camera.

10.3. Camera Link Test points
Inside the camera Link versions cameras CV-M4+CL and CV-M7+CL there are some useful test
points, which can be a big help in system troubleshooting.
The timing signals are multiplexed into the Camera Link, so it is not possible to use an
oscilloscope to control the timing for a camera frame grabber system.
The 4 test points are:
TRIG Input trigger signal
EEN Exposure enable signal
FEN Frame enable (FVAL) Camera Link signal
LEN Line enable (LVAL) Camera Link signal
The test points are found on the PK8373A board shown in fig.32.
