6. Functions and Operations
In the following the format shown in “7.5. CV-M2 command list” are used for function
commands and parameters.
6.1. Basic functions
The M2 camera is a progressive scan camera with 10 or 8 bit video output in single or dual
channel Camera Link. On a BNC connector a standard composite video output CCIR or EIA for
monitor use is found. The image covers the full format, but the resolution is much lower than
the digital video output.
An iris video signal can be used for lens iris control if the camera is in continuous mode or Reset
Continuous Trigger mode.
A knee function (and gamma for single channel) makes it possible to cover high contrast scenes.
The CV-M2 camera has 1/2, 1/4 or 1/8 partial scanning. Programmable partial scan, where the
start line and the number of lines can be selected in 1line increments is also available.
There are 5 trigger modes. Normal continuous, reset continuous trigger, edge pre-select, pulse
width control, edge pre-select burst trigger and PIV trigger. (PIV, Particle Image Velocimety).
The Sensor Gate Control can be used in normal continuous mode together with strobe flash.
The accumulation can be LVAL synchronous or LVAL a-synchronous.
In the following some of the functions are shown in details.
6.1.1. Dual video output
The video read out through Camera Link can be via a single or via double channels. (OS=0 for
single channel, OS=1 for dual channel.) If dual video outputs are used, the frame grabber PC
should reconstruct the image frame from the 2 half images.

6.1.2. Burst trigger
With the burst trigger function TR=4, five previous set edge pre-selected programmable
exposures can be done with a single trigger pulse. The five shutter times can be set with BSH1
through BSH5. (1H through 1216H.)

6.1.3. Restart continuous trigger mode
The RCT mode makes it possible to use a lens with video controlled iris for intelligent traffic
surveillance applications. TR=2. 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 and restarted,
the previous signal is dumped with a fast dump read out, and the new triggered exposure is
started. This fast dump read out has the same effect as “smearless read out”. Smear over
highlighted areas are reduced for the triggered frame.

6.1.4. PIV mode
The Particle Image Velocimetry mode can be used in applications where 2 images should be
taken with a very short time interval. TR=5. It can only be used with strobe flash or lasers as
illumination. The first accumulation time is 4 µsec. The second is as long as the time for a full
frame.

6.1.5. Sensor Gate Control
This function is for applications where a strobe flash is the only illumination, and where the
exact time for the strobe firing is not known. The time window for the strobe firing can be up to
several frames. The resulting video read out can also be delayed by this function. It makes the
synchronization of the frame grabber more flexible.
The Sensor Gate Control signal will inhibit the internal SG signal so the accumulation can
continue. The sensor gate control signal can be synchronized by the FVAL signal.
This function will only work in normal continuous mode. TR=0. The function is on if SG=1.
The SG signal is an internal signal, which is low when the accumulated charge on the photo
diode array is transferred to the vertical ccd registers for read out.
When the Sensor Gate Control input is high, the internal SG pulse is inhibited, and the signal
accumulation on the photo diode array can take place. When the strobe flash is fired, the Sensor
Gate Control signal can be low. The resulting video is then read out after the first FVAL (or SG),
following the falling edge of Sensor Gate Control signal.

6.1.7. Knee function.
The knee functions can compress the signals in the highlighted areas. The slope over the knee
point is only 20%. The Knee point can be adjusted from 712 to 1023. With the knee at 890, the
camera can reproduce scene highlight up to 175%. The image contrast is reduced to 20% for
scene luminance higher than the knee point.
This function can be used in applications where the scene brightness is divided in an area in
shadow, and another in bright sunshine.

6.2.7. 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. (Single channel 47.9 µsec.
Dual 27.3 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 LVAL synchronous accumulation mode a new trigger can start a new exposure during the
previous frame read out, but the exposure may not be finished before the frame is read out. It
makes it possible to have a trigger rate close to the frame rate. (1 FVAL + 3 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.

6.2.9. Partial scanning vertical timing
Partial scanning has 3 pre-selected vertical centred areas 1/2, 1/4 and 1/8. SC=1 through SC=3.
With SC=3, the start and the height of the partial scanned area can be programmed with 1 line
interval. The start line can be programmed with PS=1 through 1151. The scanned height can be
programmed with PC=50 though 1200. Partial scanning will operate with single or dual channel
output. Partial scan is done by a high-speed dump read out of the areas over and under the area
of interest. This partial scanned area is read out with normal speed. The high-speed dump read
out (Front of Frame and in Back of Frame) is done with a speed 18 times faster for single
channel, and 10 times faster for dual channel.
The figures on the timing diagram below are for 1/2 partial scanning.

All figures marked with (*) will change with other partial settings. See table below. 1LVAL = 47.9 µsec (single). 27.3 µsec (dual).
Fig. 23. Partial scanning vertical timing
The following table shows the figures for partial scanning.
The maximum frame rate (FPS) for single and dual channel readout is shown for normal mode.
TR=0. For triggered modes it will be lower, because the accumulation time is added to the read
out time. 1LVAL = 47.9 µsec (single). 27.3 µsec (dual).
It is not possible to synchronize the camera from an external sync source except by an extern
trigger pulse. The camera will always run with its internal X-tal controlled timing.
Trigger input through Camera Link. TI=0
Trigger input as TTL on pin #10 on 12 pin Hirose. TI=1
The trigger polarity is active low. TP=0
Trigger input can be changed to active high. TP=1
6.3.2. Output of Timing Signals
To synchronize the video data transfer from the camera the following signals are available in a
base configuration of Camera Link:
FVAL Frame valid High for valid Frame
LVAL Line valid High for valid line
PCLK Pixel clock Rising for data stobe
DVAL Data valid High for valid data
EEN Exposure enable Low during exposure.
See the full connector pin assignment for Camera Link in chapter 5.3 and 5.4.5
For complete documentation on the Camera Link standard, please contact your JAI distributor.
EEN is also found as a TTL signal on pin #9 on the 12 pin Hirose. EEN is low during exposure.
(Not specified by CL).
6.4. Trigger Modes
This camera can operate in 6 primary modes. 1 non-triggered mode and 5 external trigger
modes, which can be set by RS-232C commands.
1. Normal continuous Mode. TR=0 Pre-selected exposure. (SM=0, SM=1)
4. Pulse Width Control Mode. TR=3 Pulse width controlled exposure.
5. Burst Trigger mode Mode. TR=4 5 EPS. Read out by trailing trig. edge.
6. PIV Mode. TR=5
In normal continuous mode and 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 1216 steps programmable (SM=1).
Pulse width control can be used for long time exposure. The trigger pulse width can be from 2
LVAL to ∞. The exposure time is not recommended to exceed 2 seconds.
Partial scan (SC=0 through 3) can be used in all 6 modes.
Important note on changing trigger modes by RS-232C and CL.
Disconnect or stop the trigger input before changing mode by RS-232C or Camera Link. In worst
case it can lead to latch-up of camera function and communication if a mode command is
received at same time as a trigger pulse. The modes are trigger modes (TR) and scanning (SC).
The camera latch-up can only be reset if the power is switched off and on again.

CV-M2
6.4.1. Continuous Operation (Non triggered)
Mode settings can be done with RS-232C. Trigger Mode Normal. TR=0. It is for applications where
the camera is continuously running without external trigger. The shutter mode can be normal or
programmable exposure. (SM=0, SM=1). The shutter will work in all 10 steps up to 1/14,000
second or with the programmable exposure in 1216 steps. In partial scanning, shutter times
longer than the actual frame time has no meaning. The exposure will be equal the frame time.
In this mode it is possible to have CCIR/EIA composite analogue video output for monitor use. It
is for full scan only. The video can be 50 or 60 frames per second with a line frequency at 15.734
kHz. CCIR has 290 active lines. Shutter speed <313 LVAL. EIA has 240 active lines. Shutter speed
<263 LVAL.
To use this mode:
Set function: Trigger mode “Normal” TR=0 Shutter mode “Normal” or “Programmable” SM=0, SM=1 “Shutter Speed” SH=0 through 9
“Programmable exposure” PE=1 through 1216
Scanning format SC=0 through SC=4
Output select OS=0, OS=1, OS=2
Polarity and other functions
Important notes on using this mode.
• Analogue video output OS=2 only for full SC=0

CV-M2
6.4.2. Edge Pre-select Mode
In EPS mode, the trigger leading edge will start an exposure at the first LVAL pulse if LS=0, (or
immediately if LS=1), and it stops and the resulting image is read out after the pre-selected
shutter time. It can be the 10 steps in normal or 1216 steps in programmable. SM=0 or SM=1.
This mode will operate with full and partial scanning.
An EEN pulse will indicate the active accumulation time, and a FVAL pulse indicates that the
resulting video is read out.
To use this mode:
Set function: Trigger mode “Edge Pre-select” TR=1
LVAL synchronous accumulation LS=0, LS=1
Shutter mode “Normal” or “Programmable” SM=0, SM=1 “Shutter Speed” SH=0 through 9
“Programmable exposure” PE=1 through 1216
Scanning format SC=0 through SC=4
Output select OS=0, OS=1
Polarity and other functions
Input: Ext. trigger to Camera Link or pin 10 on 12-pin connector.
Important notes on using this mode.
• The duration of the trigger should be >2LVAL to <3FVAL.
• If LS=0 (Synchronous accumulation), the minimum trigger interval is 1 FVAL + 3 LVAL. The
new exposure should not be finish before the previous frame is read out.
• If LS=1 (Asynchronous accumulation) the minimum trigger interval is the exposure time +
3 LVAL. A new trigger must not be applied before FVAL is low.
• 1LVAL = 47.9 µsec (single). 27.3 µsec (dual).
For horizontal timing refer to 6.2.3 through 6.2.6. (Fig.17. through fig. 20.)

6.4.3. Restart 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, a new triggered exposure is started and read out as normal.
The fast dump read out is performed with a speed 18 times faster for single output, and 10 times
faster for dual output. 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 restart continuous trigger mode makes it possible to use a lens with video controlled iris in
intelligent traffic surveillance applications.
To use this mode:
Set function: Trigger mode “Restart continuous trigger” TR=2
LVAL synchronous accumulation LS=0
Shutter mode “Normal” or “Programmable” SM=0, SM=1 “Shutter Speed” SH=0 through 9
“Programmable exposure” PE=1 through 1216
Scanning format SC=0 through SC=4
Output select OS=0, OS=1
Polarity and other functions
Input: Ext. trigger to Camera Link or pin 10 on 12-pin connector.
Important notes on using this mode.
• The duration of the trigger should be >2LVAL to <3FVAL.
• A new trigger must not be applied before the triggered data is read out.
• 1LVAL = 47.9 µsec (single). 27.3 µsec (dual).
• The time for the fast dump read out (smearless) is 3.3 msec.
For horizontal timing refer to 6.2.3. through 6.2.6. (Fig.17. through fig. 20.)

6.4.4. Pulse Width Control Mode
In PWC mode, the trigger leading edge will start an exposure at the first LVAL pulse if LS=0 (or
immediately if LS=1). It stops at the trailing edge of the trigger pulse, and the resulting video is
read out. This mode will operate with full and partial scanning. An EEN pulse will indicate the
active accumulation time, and a FVAL pulse indicates that the resulting video is read out.
Long time exposure can be done with pulse width control mode.
To use this mode:
Set function: Trigger mode “Pulse width control” TR=3
LVAL synchronous accumulation LS=0, LS=1 Scanning format SC=0 through SC=4
Output select OS=0, OS=1
Polarity and other functions
Input: Ext. trigger to Camera Link or pin 10 on 12-pin connector.
Important notes on using this mode.
• The duration of the trigger can be >2LVAL to ∞. Thermal noise and dark current noise will
increase by accumulation time, therefore the exposure time is not recommended to
exceed 2 seconds.
• If LS=0 (Synchronous accumulation), the minimum trigger interval is 1 FVAL + 3 LVAL. The
new exposure should not be finished before the previous frame is read out.
• If LS=1 (Asynchronous accumulation) the minimum trigger interval is the exposure time +
3 LVAL. A new trigger must not be applied before FVAL is low.
• 1LVAL = 47.9 µsec (single). 27.3 µsec (dual).

6.4.5. Burst Trigger mode
With the burst trigger function, a single trigger pulse can start a sequence with five previous set
pre-selected programmable exposures. The five shutter times can be set with BSH1 through
BSH5. (Exposure 1H through 1216H.) The exposure is LVAL synchronous.
The sequence will start with the first exposure at the first LVAL pulse after the trigger leading
edge, and the result is read out after the selected shutter time. During the read out of the
previous frame, the next exposure starts. It will continue until exposure 5 is read out.
This mode will operate with full and partial scanning.
An EEN pulse will indicate the active accumulation time, and a FVAL pulse indicates that the
resulting video sequence is read out.
To use this mode:
Set function: Trigger mode “Burst EPS” TR=4
LVAL synchronous accumulation LS=0
Burst Shutter 1 BSH1=1 through 1216
Burst Shutter 2 BSH2=1 through 1216

6.4.6. PIV mode.
PIV mode (Particle Image Velocimetry) can be used in applications where 2 images should be
taken with a very short time interval. It can only be used with strobe flash as illumination. The
first accumulation time is fixed at 4 µsec. After a delay >1.5 µsec. the second exposure period
starts. It is as long as the time for a full frame. The accumulation is LVAL a-synchronous. The
first exposure period starts at the trigger leading edge. The first strobe flash should be fired
within the first exposure period, and the second strobe flash during the first frame read out
period. The result will then be 2 frames exposed with the flash interval.

8. If 8 bit is selected it is the 8 most significant bits. For the bit allocation in Camera Link
output, please refer to “5.4.5. Camera Link interface” and to fig. 7.
MN: Monitor mode
In normal mode (TR=0) and full frame (SC=0) the output command (OS=2) selects the composite
analogue monitor video system. MN=1 for CCIR (50 FPS, 313 lines, 290 active lines). MN=0 for EIA
(60 FPS, 263 lines, 240 active lines). The line frequency is 15.734 kHz. The video can be seen on
a standard monitor with the command OS=2. SW1.1 can also be used. SW1.1 has highest priority.
TI: Trigger input select
To select the trigger input via Camera Link or pin #10 on Hirose connector as a TTL signal. The
trigger input can also be selected by the internal switch, which has highest priority.
TP: Trigger polarity
This command can change the trigger polarity.
GS: Gamma select
To select gamma 1 or 0.45. 1 is linear relation between scene luminance and video output. 0.45
will expand the contrast in dark and compress the contras in light parts of the scene.
RP: Rear pot
Select master gain from the potentiometer or RS-232C. Sw1.4 has highest priority.
AU: Auto dual adjust
This function is used to calibrate the 2 channels to have same black level and gain.
ABA (Automatic Black Adjust) is a one-push function to align the black level for the 2 channels.
AWA (Automatic White Adjust) is a one-push function to align the white level for the 2 channels.
BL: Black level master
BLF: Black level fine. Right
To adjust the black level for both channels and to fine adjust the R channel.
GA: Gain level master
GLR: gain level fine. Right
To adjust the gain for both channels and to fine adjust the R channel.
KL: Knee point master

7.6. Camera Control Tool for CV-M2
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.
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. Below the different windows are shown.

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.
