CV-M2CL and CV-M8CL

1. General
The CV-M2CL and CV-M8CL are digital 2 megapixel monochrome and color cameras designed for
automated imaging and ITS (Intelligent Traffic Systems) applications, featuring high resolution
and high speed within a uniform and compact housing.
The color version CV-M8CL is based on a CCD sensor with primary Bayer color mosaic filter. The
color reconstruction should be done in the host PC.
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.
Functions like burst trigger, reset continuous trigger mode, analog iris video output, knee and
gamma function for single channel makes the camera suitable for intelligent traffic systems.
The CV-M2CL/M8CL features the Camera Link standardized multiplexed signal output interface.
The CV-M2CL revision B starting with sn. E520301 is updated with a new CCD sensor. The sensor
gate control mode (SG) is removed. Some minor bugs in the firmware are solved.
The CV-M2CL revision C includes the color version CV-M8CL revision C, and has new updated
boards. For CV-M2CL a vertical binning function has been added.
Revision D is without binning, and some boards are updated.
The latest version of this manual can be downloaded from: www.jai.com
The latest version of Camera Control Tool for CV-M2/M8 can be downloaded from: www.jai.com
For camera revision history, please contact your local JAI distributor.

The analog video output without composite sync on
pin #4 12 pin Hirose connector is a 75 ΩDC coupled
circuit. It can be used for iris control if the camera is
in normal continuous mode or Reset Continuous Trigger
mode. Iris video is added from both channels.
Black level is –0.6 volt without termination.
Important note on using this signal for iris control.
The signal for iris video output is taken from the video signal after the gain control. If it is used
for auto iris control, output video level can only be adjusted on the lens level adjust.
Fig. 4. Video output.
5.4.3. Trigger input
The trigger inputs on pin #10 12 pin Hirose
connector is AC coupled. To allow a long pulse
width, the input circuit is a flip flop, which is
toggled by the negative or positive differentiated
spikes caused by the falling or rising trigger
edges.

5.4.5. Camera Link interface
The video output is Camera Link, where the 2 channels with 10 or 8 bit video are placed in a
base configuration. The digital output signals follow the Camera Link standardized multiplexed
signal output interface. The output driver is NS type DS90CR285, and the receiver is NS type
DS90CR286.
The data bits from the digital video, FVAL, LVAL, DVAL and EEN are multiplexed into the twisted
pairs, which are a part of the Camera Link. Trigger signals and the serial camera control are
feed directly through its own pairs. The trigger input can also be TTL on the 12 pin connector.
(TI=0 for CL. TI=1 for 12 pin). The serial camera control can be switches between the 12 pin
connector or CL by an internal switch SW 700 (HR/CL). Refer to 7.2
The 26 pin MDR connector pin assignment follows the Camera Link base configuration.

standard specifications found on www.jai.com

6. Functions and Operations
In the following the format and the abbreviations shown in “7.5. CV-M2/M8 command list” are
used for function commands and parameters.
6.1. Basic functions
The M2/M8 cameras are a progressive scan camera with 10 or 8 bit video output in single or dual
channel Camera Link. On a BNC connector on M2, 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. For M8 it is not a correct monochrome image because the Bayer
pattern.
An iris video signal can be used for lens iris control if the camera is in continuous mode or Reset
Continuous Trigger mode.
For M2 a knee function (and gamma for single channel) makes it possible to cover high contrast
scenes.
The CV-M2/M8 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 Velocimetry).
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. Reset 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.

The Particle Image Velocimetry (PIV) mode (TR=5) 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 or lasers as
the only illumination. The first accumulation time is 4 µsec. The second is as long as the time for
a full frame.

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. Knee point at max (1023) is
the same as knee function off. 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.
