1. General

The LQ-050CL is a 4CCD line scan camera using four 512 pixel line sensors mounted on a prism, for
the R, G,B and NIR channels. It operates with a 40 MHz pixel clock, resulting in a maximum line rate
of 70,922 lines per second.
The camera outputs digital data in 4 x 8 bits or 4 x 10 bits format via Camera Link. The camera is
configured by software through the serial communication port of the Camera Link interface, or via
RS-232C through a 12-pin Hirose connector.
The camera accepts M52 mount or F-mount lens.

The LQ-050CL is a suitable camera for various applications such as inspection of fruits,
vegetables ,circuits boards or electronic/mechanical parts, as the NIR image can catch scratches or
blemishes on object surfaces which the RGB color image cannot find.

The latest version of the operation manual can be downloaded from www.jai.com .
The latest camera control tool for the LQ-050CL can be downloaded from www.jai.com .

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 a DIP switch setting (SW 1).

Fig. 6 Trigger input (12-pin Hirose)

LQ-050CL

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

Fig.9 Signals flow

The LQ-050CL uses four high-performance CCD line scan image sensors mounted on a prism
block. 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 Pulse 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 LQ-

050CL

the exposure time can be set individually for all four channels.

6.2.1 No-Shutter mode with internal trigger

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 (T

exp

= 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 pre­determined.

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. The line rate is automatically adjusted in order to 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=564 to 577536 clocks

(14.10µs to 14.438ms 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

6.2.2 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
Minimum Trigger Interval 14.2μs

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.

 Only gain-based one-push white balance function (WB) is available with this mode
 The minimum trigger interval is 14.20μs.

6.2.5 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:

TTL input via 12P 14.2μs (TTL interface)

Camera link input 14.2μs (CameraLink interface)

 One-push white balance by gain setting only.
 The trigger interval is more than (Exposure period + 52.6μs).

7. Functions listed alphabetically by command acronyms

7.1 Command AHRS – Request Status After One-Push AWB

This command returns the status of the one-push AWB function, with the following

parameters:
0=AWB not completed yet
1=Succeeded
2=Error1: Green image too bright
3=Error2: Green image too dark
4=Error3: Timeout occurred

7.2 Command AL – Automatic Line Rate Reference Level

This command is a target of luminance level when command AR is activated.
Settings: 0 to 1023 (for both 8-bit and 10-bit)
Applicable modes: No-Shutter with internal trigger

Shutter Select with internal trigger

Associated functions: Command AR

7.3 Command AR – Automatic Line Rate Setting

The line rate can be adjusted from 1L to 1024L. This function will calculate and set the

line rate of the camera based on the Automatic Line Rate Reference Level (as set in

command AL) and the scene illumination. Please note that the aspect ratio of the scanned

object will change as the line rate is changed.

Settings: 0 (activate automatic process)

Applicable modes: No-Shutter with internal trigger

Shutter-Select with internal trigger

Associated functions: Command AL

Note

 The data can be stored in the camera memory for next start up.

7.4 Command ARST – Auto Reset Mode

This function enables/disables the Auto Reset mode, which prevents offset rising in special

case where line triggers are not received for long periods of time.

Settings 0 (off) and 1 (on). Factory default is 0 (off).

In this mode, when a trigger pulse does not occur after more than 53ms, the LQ-050CL

automatically returns to the internal trigger mode with the line rate of approx. 14.1μsec.

In this time, the camera operates by the internal trigger, and if the external trigger is input,

the video is immediately output. In the Shutter-Select mode, the exposure starts

immediately after the trigger is input and the camera outputs the video. In the No-Shutter

mode, the exposure will start immediately after the trigger is input, but the video output

is available after the second trigger pulse is input. In this ARST mode, DVAL, EEN and

Video OUTPUT are disabled in order to prevent charges due to dark current from building

up in the sensor during standby periods and only LVAL is output

.

LQ-050CL

25

7.5 Command AH - Activate One-Push Auto White Balance (AWB) - Shutter

By sending this command via the serial communication, the shutter based One-Push AWB

function is activated. The white balance function takes approximately 3 seconds to

complete. During this time the rear panel LED will show orange.

This function operates in two steps. First the red-to-green channel difference and the

blue-to-green channel difference are calculated separately. Then the exposure time of

the blue and red channels are automatically adjusted, to obtain the same output level on

all three channels.

Settings: 0 = activate automatic process

Applicable modes: Shutter-Select mode only

Associated functions: Command WB

Note:

 When color temperature of illumination exceeds the range of adjustment, proper white

balance may not be obtained.

 The data can be stored in camera memory for use at next start up.
 This function can work in external trigger mode.
 The S/N ratio of the output will remain constant for all channels

7.6 Command AW – Activate One-Push Auto White Balance (AWB) - Gain

By sending this command via the serial communication, the gain based One-Push AWB

function is activated. This function can also be initiated by pressing the rear panel

button. The white balance function takes approximately 3 seconds to complete. During

this time the rear panel LED will show orange.

This function operates in two steps. First the red-to-green channel difference and the

blue-to-green channel difference are calculated separately. Then the gain of the blue

and red channels are automatically adjusted, to obtain the same output level on all three

channels.

Settings: 0 = activate automatic process

Applicable modes: All

Associated functions: Command WB

Rear panel one-push WB button.

Note:

 When color temperature of illumination exceeds the range of adjustment, proper white

balance may not be obtained.

 The data can be stored in camera memory for use at next start up.
 This function can work in external trigger mode.
 The S/N ratio of the output will change as a result of this function.

7.7 Command BA – Bit Allocation

This function lets the user select whether the video data is presented as 4 x 8 (32)-bit or

4 x 10 (40)-bit in the Camera Link output. The internal processing in the camera is based

on a 12-bit A/D signal. The 32-bit and 40-bit function removes the least significant bits

from the 12-bit signal.

Settings: 0=8-bit, 1=10-bit

Applicable modes: All

LQ-050CL

26

7.8 Command BI – Binning (horizontal only)

This function reduces the number of pixels to 256 without affecting the line rate. Two

adjacent pixels are combined at the output stage and read out as one pixel. Sensitivity is

doubled as a result of binning.

Settings: 1=binning on, 0=binning off

Applicable modes: All

Note

 Setting data is stored in camera memory for use at next start up

 This function is available for all modes.

7.9 Command BL – Master Black Level

This command is a global black level adjustment for all channels. There are two adjustment

ways, one is “Master Tracking” and the other is “Individual”. The adjustable range for

master black is 0 LSB to 255 LSB. The LQ-050CL has an automatic black level clamp function.

This circuit is an analog circuit and after the signal level of dummy pixels is clamped at the

constant level, it is digitized and the OB level is clamped at 32 LSB (8 LSB) in the digital

clamp circuit. This function is always operating.

The number in the parenthesis is for 8bit.

Master Mode : Master(G): 0 to 255LSB (10-bit output)

Individual Mode : G ch : 0 to 255LSB (10-bit output)

Associated functions: Commands BLR, BLB, BLIR

7.10 Commands BLR , BLB and BLIR – Black Level Red, Blue and NIR

In conjunction with Command BL, these commands allow individual setting of the black

level in all channels.

Master Mode : -128 to 127 LSB (10-bit output)

BLR,BLB and BLIR can be set from -128LSB to 127LSB at the

setting value of the master gain. In this case, total range should

be within 0LSB to 255LSB.

For instance, it the master is set at 100, BLR, BLB and BLIR can

be set from -100 to 127LSB.

Individual Mode 0 to 255LSB (10-bit output)

Associated functions: Command BL

7.11 Command BLM - Black Level Mode

Select the black level adjustment method

Settings 0=Master tracking
1=Individual (Factory default)

LQ-050CL

27

7.12 Command EI – Interlocked R, G, B & NIR Exposure

When this function enabled (interlocked), exposure time for all four channels is selected

by setting the green channel and the red, blue and NIR channels will track.

To obtain white balance, adjust red and blue channels, PER and PEB. It is thereafter

possible to adjust overall exposure time by using the command PEG. The red and blue

channels will track the green channel proportionally, thus maintaining white balance

settings.

Settings: 0= OFF (independent R, G,B and NIR settings)

1= R, B and NIR channel interlocked with G

Setting range: 50ns to {Line rate ― 52clk(1.3μs)} (Individual R,G,B & NIR) in

25ns(1 clock) step
Associated functions: Commands PER, PEG, PEB and PEIR – Programmable Exposure
Applicable modes: Shutter-Select mode only (Internal and external)

Note: The LQ-050CL has a priority for the line rate setting. If the exposure is use around
the longest exposure speed which is nearly equal to the trigger cycle, please note the
followings.

1. Shutter select mode in the internal trigger
The maximum shutter speed is the setting line rate minus 52clk(1.3μs).

2. Shutter select mode in the external trigger
The maximum shutter speed is the provided trigger cycle minus 60 clocks (1.5μs) .

7.13 Command GA – Master Gain Level

This function is a global gain adjustment for all channels. There are two ways to adjust

gain, one is “Master Tracking” and the other is “Individual”. Command GM selects

a required mode. The gain setting is done in the analog domain where 1LSB
equals 0.03dB.

Master Mode: Master(G): -123 to 429(-3dB to +12dB)

Individual Mode: G: -363 to 660 (-9dB to +18dB)

Associated functions: Commands GAR, GAB, GAIR - Gain level red, blue, and NIR.

Note: The adjustment range is available under 7800K light. If light with a color

temperature other than 7800K is used, the adjustable range might be limited.

7.14 Commands GAR, GAB and GAIR – Gain Level Red, Blue and NIR.

In conjunction with the Command GA, this function allows the individual setting of gain for
all channels, or it can be used for fine adjustment after one push white balance is executed.
It is important to note that increasing the gain will lead to an increased noise level and
reduced S/N-Ratio. 1LSB equals 0.03dB.

Master Mode: -231 to 231 (-6dB to +6dB)

7.19. Command NR - Noise Reduction

Noise levels less than 16 LSB (4LSB) which are superimposed on the video signal will be

eliminated. The deterioration of spatial frequency is minimized. The improvement of
signal-to-noise ratio will be 3dB as the maximum although it depends on the object.

Figure in ( ) is for 8-bit output.

Settings: 0=ON, 1=OFF

7.20 Command PBC – Enable Pixel Black (FPN) Correction

This command enables (or disables) the “pixel black level” correction function, which
compensates for Dark Signal Non Uniformity / Fixed Pattern Noise (DSNU / FPN) for
individual pixels.

Settings: 0 = Off (Deafult)

1 = Factory setting

2 = user area

Associated functions: Command PBR
Applicable modes: All

7.21. Command PBR – Run Pixel Black Correction and Store to User Area

This command initiates the “pixel black level” correction function, and stores the

settings in the user area. When this function is activated, lens must be capped.

Settings: 0 = Run this function
Associated functions: Command PBC must be set to 2

Note:

 This function requires that no light reaches the image sensors. The lens must therefore

be covered by a lens cap, or put the F-mount protective cover on the camera, when
executing this function.

 As the black level is influenced by the exposure time (especially for long exposure

times at slow scan rates) it is recommended to perform the pixel black correction at
the exposure time and line rate at which the camera will be operated.

Setting point

LQ-050CL

Principle of Pixel black level correction (DSNU / FPN correction)

Dark Signal Non-Uniformity or Fixed Pattern Noise is, as the name implies, fixed pattern
on the sensor output, which is not dependent on the incoming light.

To correct for DSNU/FPN, the camera’s 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 dependent 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.

7.22. Command PBS - Request Status After Pixel Black Correction

This command returns the status of the pixel black correction, with the following
parameters:

0=Not completed yet
1=Succeeded
2=Error1: Image too bright
3=Error2: Image too dark
4=Error3: Timeout occurred

7.23. Command PER,PEG,PEB and PEIR – Programmable Exposure for R,G,B,and NIR

This command allows individual setting of the exposure time for each channel. It is only
valid for the Shutter-Select mode (see chapter 6.2)

Settings: 2 to 577,536 in 25ns steps
Associated functions: EI =0 (R,G,B and NIR independent)

EI=1 (R , B and NIR exposure interlocked with G)

Applicable modes: Shutter-Select (internal/external trigger)

Note:
The actual exposure time (ns) is calculated as follows:
T

exp

= 25ns x (Repetition Period (clk) – (T1 (clk) +21clk) )
Where,
Repetition Period is line rate or trigger interval
T1 is programmable exposure setting value and 21clk is a fixed value.

7.24. Command PGC – Enable Flat-Field Correction (pixel gain)

This command enables (or disables) the “pixel gain” (flat-field) correction function,
which compensates for Pixel Response Non Uniformity (PRNU) for individual pixels.
The algorithm for compensation is different in No-Shutter mode and Shutter-Select mode.
If the operating mode is changed, an adjustment in the selected mode must be made.
The factory default is Shutter-Select mode.

Settings: 0=Off (Default)
1=Factory Setting
2=User area
Associated functions: Command PGR
Applicable modes: All

7.25. Command PGR – Pixel Gain Correction and Store in User Area

This command initiates the pixel gain correction function, and stores the settings in the
user area.

Settings: 0= activate automatic process
Associated functions: Command PGC must be set to 2

Note:

 The image sensors must not be saturated when executing this function.
 When executing this function, the exposure time and line rate should be the same as

when the camera is operated in the application.

Operating procedure for individual R, G and B channel shading correction:

1. Before making adjustment, approximately 30 minutes of warm up is required.

2. Make sure the output signal is not saturated (<80% of full output is recommended)

3. Set command PGC=2.

4. Set command PGR to 0 to initiate shading correction.

5. If desired, set command SDR to 0 or 1 to activate shading correction to correct the

shading caused by lens or lighting. When the shading correction is performed, the
flat­field correction must be activated before the shading correction is performed.

Principle of Pixel Gain (flat-field) correction (PRNU correction)

Pixel Response Non-Uniformity is, as the name implies, 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 a factor greater or less
than 1. These coefficients are stored in a non-volatile memory, and are therefore
maintained after power down.

7.26. Command PGS - Request Status After Pixel Gain Correction

This command returns the status of the pixel gain correction, with the following
parameters:

0=Not completed yet
1=Succeeded
2=Error1: Image too bright
3=Error2: Image too dark
4=Error3: Timeout occurred

7.27. Command SDC – Select Shading Correction Mode

This function enables (or disables) shading correction.

Settings: 0 = off (Bypass) (Default)
1 = Factory setting
2 = User area
Associated functions: Commands PGR, SDR and SDS

7.28. Command SDR – Run Shading Correction

This function initiates automatic shading correction, and stores the result to the user
area. This function should be used together with the flat-field correction (commands PGC
and PGR). There are two types of shading correction: Individual R, G and B channel
correction and chromatic shading correction.

After correction: flat response from pixel to
pixel

Light source : 7800K, LED white light source
Lens used: f35mm, F2.8 lens

(A) Flat shading correction (SDR=0)

Shading is calculated and individually compensated for R, G ,B and NIR channels
respectively. The compensation range is within 30% as compare with the highest
brightness in the previous line.

Note:

 Depending on the optics and/or illumination used together with the camera, it may not

be possible to fully compensate for shading.

Operating procedure for individual R, G ,B and NIR channel shading correction:

1. Before making adjustment, approximately 30 minutes of warm up is required.

2. Make sure the output signal is not saturated (<80% of full output is recommended)

3. Set command PGC=2 and SDC=2.

4. Set command SDR to 0 to initiate shading correction.

5. If desired, set command PGR to 0 to activate flat-field (pixel gain) correction to

correct for pixel response non-uniformity.

6. Again set SDR=0 after running the flat-field (pixel gain) correction

(B) Chromatic shading correction (SDR=1)

In this mode, shading correction of R ,B and NIR signals are referenced to the G signal

which is the reference. When the green channel detects “undulating” or “parabolic” type

shading, R and B channels are compensated to follow the same curve.

Appendix

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 settings.

2. Typical Sensor Characteristics

The following effects may be observed on the video monitor screen. They do not indicate any fault
of the camera, but are associated with typical sensor characteristics.

V. Aliasing

When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged image on the
monitor may appear.

Blemishes

All cameras are shipped without visible image sensor blemishes.
Over time some pixel defects can occur. This does not have a practical effect on the operation of
the camera. These will show up as white spots (blemishes).
Exposure to cosmic rays can cause blemishes to appear on the image sensor. Please take care to
avoid exposure to cosmic rays during transportation and storage. It is recommended using sea
shipment instead of air flight in order to limit the influence of cosmic rays on the camera. Pixel
defects/blemishes also may emerge due to prolonged operation at elevated ambient temperature,
due to high gain setting, or during long time exposure. It is therefore recommended to operate the
camera within its specifications.

Patterned Noise

When the sensor captures a dark object at high temperature or is used for long time integration,
fixed pattern noise may appear on the video monitor screen.

3. Caution when mounting a lens on the camera

When mounting a lens on the camera dust particles in the air may settle on the surface of the lens
or the image sensor of the camera. It is therefore important to keep the protective caps on the lens
and on the camera until the lens is mounted. Point the lens mount of the camera downward to
prevent dust particles from landing on the optical surfaces of the camera. This work should be done
in a dust free environment. Do not touch any of the optical surfaces of the camera or the lens.
