The CV-L107CL follows the Camera Link standard in all respects.
Please refer to the Camera Link version 1.1 specifications for detailed information on bit
assignments of 24-bit RGB and 30-bit bit output.
5.3. Input and output circuits
5.3.1. Trigger input
The External Trigger signal can be applied either through the Camera Link connector or at pin 10 of
the 12-pin Hirose connector. The command to change this setting is TI (Trigger Input). TI=0 for
Camera Link connector (factory default) and TI=1 for 12-pin Hirose connector. The input via the
12-pin Hirose connector is AC coupled.
To allow long pulses, which may be required when using the Pulse Width Control (PWC) trigger
mode, the input circuit is designed as a flip-flop circuit. The leading and trailing edges of the trigger
pulse activate the circuit.
The trigger input polarity can be changed by the command TP. At the 12-pin Hirose connector the
External Trigger input is 4V ± 2V (TTL). It can be changed to 75 ohm termination by an internal
switch setting (SW 801-2).
Fig. 4 Trigger input (12-pin Hirose)

5.3.2. EEN / XEEN output (Exposure ENable)
This output corresponds to the exposure (accumulation) time of the camera. It works together with
all operation modes. It is, however, not active when the test pattern function is enabled.
The EEN signal is available at the Camera Link connector and at the 12-pin Hirose connector at the
same time.
At the Camera Link connector this signal has positive logic.
At pin 9 of the 12-pin Hirose connector the signal has negative logic, and is therefore named XEEN.
The output circuit is a 75 ohm complementary emitter follower. The circuit is powered from the 5V
supply, resulting in an output level of more than 4V. It is not terminated.

6. Functions and Operation
6.1. Basic functions
The CV-L107CL is built around three high-performance CCD line scan image sensors mounted on a
prism block, as illustrated in Figure 6.
During exposure, the incoming light is converted to electrons (electric charge) in the photodiodes
(active pixels). The transfer gate controls the transfer of charge from photodiodes to the shift
register. Activating the transfer gate terminates the exposure cycle, transfers the charge to the
Horizontal Shift Register (2-phase buried channel CCD shift register) and starts a new exposure
cycle. The line is subsequently read out in a single sequence starting with pixel 1.
The exposure time is normally the same as the cycle time (in No-Shutter mode). By using the
Exposure Control Gate (in Shutter-Select or Pulsed Width Control trigger modes) the exposure time
can be individually set to be shorter than the cycle time (the inverse of line rate). This also allows a
fixed exposure time, independent of the line rate. In the CV-L107CL the exposure time can be set
individually for all three channels.

6.2. Pixel Gain (flat-field) correction (PRNU correction)
Pixel Response Non-Uniformity is, as the name expresses, a non-uniformity of the response of each
individual pixel. This means that for a fixed light level each pixel will have a slightly different
output level (response).
To correct for PRNU, the camera’s internal correction circuit captures one or several lines of data
under non-saturated illuminated conditions (not more than 80% of maximum - recommend level is
half of maximum), and the average across the line is calculated. Based on this average, coefficients
are then generated for each individual pixel. The coefficient has the function of multiplying the
pixel output with factor greater or less than 1. These coefficients are stored in a non-volatile
memory, and are therefore maintained after power down.
6.3. Pixel black level correction (DSNU / FPN correction)
Dark Signal Non-Uniformity or Fixed Pattern Noise is, as the name expresses, fixed pattern on the
sensor output, which is not dependant on the incoming light.
To correct for DSNU/FPN, the camera-internal correction circuit captures one or several lines of
data under dark conditions (the lens must be covered by a lens cap), and the average across the line
is calculated. Based on the average, coefficients are then generated for each individual pixel. The
coefficient has the function of adding or subtracting a value to the pixel output. These coefficients
are stored in a non-volatile memory, and are therefore maintained after power down.
As the dark signal is highly dependant on the exposure time, this correction must be performed
under the operating conditions (exposure time and line rate) that will be used by the application.

6.4. Shading correction
Shading is caused either by illumination with uneven distribution of light across the surface, or by
vignetting towards the edges of a lens.
The shading correction incorporated in the camera will compensate for this effect by as much as
20% of the brightest signal.
Shading is not compensated for each individual pixel. The signal is averaged across group of 8 pixels
in relation to the whole line. The pixel response non-uniformity will be superimposed on the output
also after shading correction has been performed. Therefore, it is recommended to perform a pixel
gain (flat-field) correction after shading correction.
The Pixel Gain (flat-field) correction function will also be used to compensate for shading, but it
cannot handle a very wide dynamic range.
The shading correction can be configured to compensate each channel separately or tracking the
green channel.
6.5. Binning
The binning function in this camera combines the charge collected in two adjacent pixels. This
halves the effective resolution to 1024 pixels, but doubles the sensitivity. The line rate is not
affected by binning.

6.6. Operation modes
The CV-L107 provides three basic modes of operation: No-shutter, Shutter-Select and Pulse Width
Control (PWC). The Shutter-Select and PWC modes also allow the user to set the exposure time
independently from the scan rate, by making use of the electronic shutter (the Exposure Control
Gate of the CCD sensor).
The following sections describe these modes. The detailed timing of the video output, shown in
figure 8, is common to all modes.

6.6.1. No-Shutter mode with Internal line rate generator
In this mode the camera does not accept an external trigger signal, as the line rate is generated
from an internal clock (user programmable, command LR). The exposure time is directly
proportional to the line rate (Texp = 1/line rate). This mode is used when there is no external trigger
signal available, and the speed of the object is fixed or can be pre-determined.
The line rate can be varied from 1 line period (L) to 1024L in 1 clock (25ns) steps. 19 kHz down to 18
Hz. When using this mode, a special function called “One-push Auto Line rate” is available. This
mode automatically maintains a constant output level by changing the line rate. See chapter 7
(configuring the camera) for further details on this function. The line rate is automatically adjusted
in order maintain sensitivity without reducing the S/N ratio.
To use this mode:
Set function Trigger mode, No-Shutter TR=0
Trigger origin, internal TG=0
Line rate LR=2100 to 2150400
(52.5 µs to 53.8 ms in 25ns increments)
Optional functions when using this mode:
One-push auto line rate AR=0
Auto line rate reference AL=0 to 1023
One-Push white balance WB
Fig. 9 No-Shutter mode with Internal line rate generator
Important Note
The “one-push auto line rate” function is not recommended for continuous web applications, as
the speed of motion needs to be adjustable in order to maintain the aspect ratio of the image.
Only gain based One-Push white balance functions (WB) is available with this mode.
Clearer timing diagram
required. No need to show
internal clock signals.

6.6.2. No-Shutter mode with External Trigger
In this mode, the exposure time is directly proportional to the line rate. The line rate is generated
externally by a trigger signal. This mode is used when an external trigger signal available, e.g. from
an encoder, and the scan rate can be controlled by this signal. The camera can accept an external
trigger through the Camera Link connector or though the 12-pin Hirose connector.
To use this mode:
Set function Trigger mode, No-Shutter TR=0
Trigger origin, external TG=1
Trigger input TI=0 or 1
Important note:
When the one-push white balance has been initiated and the rear panel LED shows orange, the
camera must receive continuous external trigger pulses corresponding to the frequency and duty
cycle used in the application.

CV-L107CL
16
6.6.3. Shutter-Select mode with Internal line rate generator
This mode allows the user to have full control of the line rate and the exposure time individually, by
programming separate timing generators. Subsequently the camera does not accept an external
trigger signal in this mode.
To use this mode:
Set function Trigger mode, Shutter-Select TR=1
Line rate LR=52.6μs to 53.683ms
Trigger origin, internal TG=0
Individual R, G and B exposure EI=0(individual)
EI=1(tracking with G)
Programmable exposure PER/PEG/PEB=2 to 2150400 (in 25ns steps)
Important note:
If using individual exposure, the EEN signal represents the channel with the longest exposure time

CV-L107CL
17
6.6.4. Shutter-Select mode with External trigger
This mode allows the user to have full control of the exposure time, by programming a timing
generator, while the line rate is controlled by an external trigger signal. The camera can accept an
external trigger through the Camera Link connector or though the 12-pin Hirose connector.
To use this mode:
Set function Trigger TR=1
Trigger origin, external TG=1
Individual R, G and B exposure EI=0(individual)
EI=1(tracking with G)
Programmable exposure PER/PEG/PEB=2 to 2150400 (in 25ns steps)
Important note:
If using individual exposure, the EEN signal represents the channel with the longest exposure time

Clearer timing diagram
required. No need to show
internal clock signals.

CV-L107CL

6.6.5. Pulse Width Control (PWC) mode
In this mode, the user has full control of both the line rate and the exposure time of each line via
the External Trigger input.
At the falling edge of the External Trigger signal, the exposure is initiated, and at the rising edge
the exposure is terminated and read out. The camera can accept an external trigger through the
Camera Link connector or though the 12-pin Hirose connector.
To use this mode:
Set function Trigger mode, PWC TR=2
Important Note:
Possible pulse width:
52.6μsec. (approx. 1 line period) to 2 sec. (there is no upper limit for the pulse width, but to
avoid image deterioration it is recommended not to exceed 2 seconds.
One-push white balance by gain setting only.
When the one-push white balance has been initiated and the rear panel LED shows orange, the
camera must receive continuous external trigger pulses corresponding to the frequency and duty
cycle used in the application.

6.6.6. Auto Reset mode
In this mode, when the interval of the trigger pulse is more than 55ms, the CV-L107CL automatically
returns to continuous operation with the line rate of 52.5μs . At this time, DVAL,EEN and Video
OUTPUT are disable in order to prohibit charge due to dark current to add up in the sensor in
standby periods.
While the Auto Reset mode is “ON”, if the trigger interval becomes less 55ms, CV-L107CL operates
in the ordinal trigger mode selected.
In the Shutter-select mode, the exposure restarts at the first trigger pulse and, after exposure, the
video signal is output.
In the No-shutter mode, the exposure restarts at the first trigger pulse but the video signal is output
after the second trigger pulse is input.
Note: CV-L107CL functions properly according the selected operation mode while the Auto Rest
mode is “ON”. However, if the system uses LVAL, it is recommended to set the Auto Reset at
“OFF”as LVAL is always output.
For this mode, CV-L107CL provides Auto Reset mode command “ARST”.
In the default setting, “ARST”is set at “0 “(OFF). In order to activate this mode, “ARST”should
be set at “1”.
The following is the concept of the Auto Reset Mode.
