1. General
The LQ-201CL is a 4CMOS line scan camera using four 2048 pixel line sensors mounted on a prism, for the R, G, B and NIR channels. It operates with an 84 MHz pixel clock, resulting in a maximum line rate of 33,014 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 connector. The camera accepts an M52 mount or F-mount lens, depending on the version selected.
The LQ-201CL 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-201CL can be downloaded from www.jai.com .

6. Functions and Operation

Fig.9 Signals flow
The LQ-201CL uses four high-performance CMOS 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 CMOS 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-201CL the exposure time can be set individually for all four channels.

6.2.1 Line rate (Command LR)
This function can set the line rate longer than 1L. Accordingly, it is possible to set the camera scan rate with the object running speed or to boost up the sensitivity by setting longer exposure time.
Adjusting range: 30.29 µs(1L) to 15.0 ms Adjusting unit: 11.9 ns
Operation mode: No Shutter/Internal Trigger and
Shutter Select/Internal Trigger
The line rate can be automatically configured (one-push auto line set) (Command:AR). This function will calculate and set the line rate of the camera based on the Automatic Line Rate Reference Level (Command :AL) and the scene illumination. This function is available on No Shutter/Internal Trigger and Shutter Select/Internal Trigger modes.
6.2.2 Electronic shutter (Exposure) (Command PER, PEG, PEB, PEIR)
This function sets the exposure time regardless of line rate setting. The exposure time can be set for red, blue, green, and NIR, respectively.
Command PER, PEG, PEB and PEIR
Adjusting range: 9.52 μs to 14.99 ms (RGB and NIR individually)
Adjusting unit: 11.9 ns (1clock) (RGB and NIR individually) Operation mode: Shutter Select/Internal Trigger and
Shutter Select/External Trigger
Note: Upper limit of operable line rate
On Shutter Select/internal trigger mode
The line rate setting is the maximum line rate for operation
On Shutter Select/external trigger mode:
The trigger interval is the maximum value.
6.2.3 External Trigger
The external trigger can be input through the 12-pin connector or Camera Link CC1. These cannot be used at the same time. The external trigger signal can be terminated by 75 ohms inside the camera (Refer to Chapter 4.2).
6.2.4 Serial communication
The camera can communicate by serial interface through the 12-pin or Camera Link interface. The default baud rate is 9600 bps.

Fig.15 Conceptual drawing for PRNU correction (1)
To correct for PRNU, the camera’s internal correction circuit captures one or several lines of data under non-saturated illuminated conditions which are 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.
Fig.16 Conceptual drawing for PRNU correction (2)
6.2.8 DSNU (Dark Signal Non-Uniformity) correction
DSNU (Dark Signal Non-Uniformity) is, as the name implies, a non-uniformity of offset level of each pixel, which is not dependent on the incoming light.
Fig.17 Conceptual drawing of DSNU correction
To correct for DSNU, 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 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.

6.2.10 Shading correction
Shading is caused either by illumination with uneven distribution of light across the surface, or by reductions in the light transmission ratio 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 groups 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 PRNU correction before shading correction.
Fig.19 Shading correction
The shading correction has two ways to compensate, flat shading correction and color shading correction.
Flat shading correction (SDR=0):
Flat shading correction compensates red, blue, green and NIR signals to be flat output. The range of compensation is within plus-or-minus 20% as compared the brightest signal level. It may not compensate enough according to the lenses and/or lighting in use. As the default, the data which is activated in the factory is stored.
Fig.20 Flat shading correction concept drawing
Note:
Depending on the optics and/or illumination used together with the camera, it may not
be possible to fully compensate for shading.

After correction: Flat dark signal response from pixel to pixel

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
Color shading correction (SDR=1):
Color shading correction compensates red, blue and NIR signals to match with green signal characteristics. The camera does not store the reference data for color shading.
Fig.21 Color shading correction concept drawing
Note:
For this function, no reference value is stored in the camera.
Operating procedure for individual R, ,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 1 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=1 after running the flat-field (pixel gain) correction
Please note that before adjusting the shading, the white balance must be adjusted.
6.2.11 Lateral chromatic aberration
This function compensates for lateral chromatic aberration of lenses. Lateral chromatic aberration causes different line lengths for the R, G, B and NIR rays at the focal point. This function enables compensation data for up to three lenses to be stored. The compensation data specifies how many pixels the R, B and NIR channels should be stretched or shortened to match the line length of the G channel which is the reference. The range of correction is minus three pixels to plus three pixels. In order to realize this function, the LQ-201CL uses an FIR (finite impulse response) filter for R, B and NIR channels. The filters response is determined by a set of 7 types of filter coefficients. The 2048 pixels that make up a line are divided in 16 blocks, with each block having 128 pixels. To compensate lateral chromatic aberration, the 7 types of coefficients are set for each block. In the factory, a default set of 112 data elements (7 types x 16 blocks) are calculated and stored.
LQ-201CL
23
Pixel number in each block: 128 pixels
Note: Restrictions for this function In order to adjust properly lateral chromatic aberration, the difference between G and R or B or NIR on right and left sides should be equal. Otherwise, the compensation may not be properly executed.
The following screen is used for creating up to three user-defined sets of lateral chromatic aberration data in the camera control tool.
Fig. 22 Setting screen for lateral chromatic aberration
Setting procedure: Please use the following steps.
1. Chromatic Aberration Enable
2. Select Lens 1, 2 or 3
3. Set the left side pixel
4. Set the area
5. Set the second block pixel
6. Set the third block pixel
Enable : Set chromatic aberration function ON or OFF. Command MAV=0(OFF) and MAV=1(ON). Lens 1,2,3 : Select a data set to use. Data for three lenses can be stored.
2048th Pixel
LQ-201CL
24
Change name : Instead of Lens 1, 2 and 3, specific names such as 28mm can be
displayed. Max. 16 alpha-numeric characters can be used.
Left side pixel : Specifies by how many pixels the left edge of the image should
be shifted. The maximum value is 3 pixels. A negative value extends the image by 1, 2 or 3 pixels. A positive value, narrows the image. Values to set are L3,L2,L1,R1,R2 and R3. L3 says to shift 3 pixels to the left and R3 says to shift 3 pixels to the right. In case of Red, CABLR=[User Lens],[Shift value] In case of Blue, CABLB=[User Lens],[Shift value] In case of NIR, CABLIR=[User Lens],[Shift value]
The range of the shift value is -3 to +3.
The following is the result of a negative setting
The following is the result of a positive setting.
Fig. 23 Operation of the compensation
Area : This command specifies the area in which pixel shifting will be applied.
The image is divided into 16 blocks, with each block representing 256 pixels. Enter a number from 1 to 8 to specify the inner edge of the pixel shifted area. The value is automatically mirrored on both the left and right sides of the image. If the left side pixel value is +/-1, only Area setting (1 to 6 blocks in fig. 25) is used and all pixels in this area will be shifted by 1 pixel. All pixels outside this area (7 and 8, white blocks) will remain un­shifted. If the left side pixel value is +/-2 or +/-3 use the 2nd Pixel Block and 3rd Pixel block fields to define a gradual shift from the edge to the center of the image.
2nd pixel block : If the left side pixel value is 2 or more pixels, enter a number in this field
to specify the block where the compensation will transition from a 2-pixel shift to a 1-pixel shift. The value entered is automatically mirrored on both the left and right sides of the image. Blocks 1 to 4 in fig.25, are where the 2 to 1-pixel shift will be applied.
3rd pixel setting : If the left side pixel value is set at +/-3, enter a value in this field to
specify the block where the compensation will transition from a 3-pixel shift to a 2-pixel shift. The value entered is automatically mirrored on both the left and right sides of the image. Blocks shown in blue (1 and 2 block) are where the 3-pixel shift will be applied.
Setting example:
Left side = -3 or 3 Area : 6, 2nd : 4, 3rd : 2
LQ-201CL
25
Fig. 24 Setting example
Note: 1) If left side pixel is set at -2 or +2, only Area and 2nd can be configured. 3rd cannot be set.
2) If left side pixel is set at -1 or +1, only Area can be configured.
Caution on calibration:
The object must be charts or materials which have clear and sharp discrimination of white and black edges. The volume of color difference in peripheral area is measured by using the image analysis software. Check how many pixels of R and B channels are shifted against G channel. In this function, maximum three pixels are compensated. For instance, if R channel is shifted 1 pixel to the left in the left end of the image, this means “-1” and set the command CABLR to 1. The compensation for the right side is automatically effected.
6.2.12 Aperture filter
LQ-400CL has a circuit for image enhancement in order to improve visible MTF. The compensation coefficient is a fixed value and cannot be changed. The factory default for this function is OFF. This function does not depend on the operating mode.
6.2.13 Binning
In this mode, the camera combines the charge collected in two adjacent pixels. This halves the effective resolution to 2048 pixels, but doubles the sensitivity. The line rate is not affected by binning. This function does not depend on the operating mode.
Fig.25 Binning reads out adjacent pixels at the same time
6.2.14 Sub-sampling
In this mode, every two effective pixels are read out. Accordingly, the read out rate is doubled. The FOV (Field Of View) is not changed versus full scan mode but the resolution becomes half.

6.3.2 No-Shutter mode with Internal Trigger
In this mode, the exposure and readout are activated by the trigger pulse generated internally. As the accumulation control is done by the internal counter, the accumulation is not affected by the trigger jitter. In this mode, the accumulation period depends on the trigger interval. Accordingly, if trigger interval becomes longer, the sensitivity is increased.
To use this mode: Set function Trigger mode, No-Shutter TR=0 Trigger origin, Internal TG=0 Line rate LR=2544 to 1260000
(30.29 µs to 15.0 ms in 11.9 ns 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
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) are available with this mode.

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:
In this mode, the shutter cannot be used. Only gain based one-push white balance functions (WB) are available with this mode. The jitter generated in the trigger input causes a variation of exposure time.

6.3.4 Shutter-Select mode with internal trigger
In this mode, the exposure and readout is activated by the trigger pulse generated internally. As the accumulation control is done by the internal counter, the accumulation is not affected by the trigger jitter. In this mode, the exposure time of R, G, B and NIR channel can be adjusted independently.
To use this mode: Set function
Trigger mode, Shutter-Select TR=1 Line rate LR=2544 to 1260000 (30.29 μs to 15.0 ms in 11.9 ns increments) Trigger origin, internal TG=0 Individual R, G, B and NIR exposure EI=0(individual)
EI=1(tracking with G)
Programmable exposure PER/PEG/PEB/PEIR=800 to 1259549
(9.52 µs to 14.99 ms in 11.9 ns increments)
Important note:
If using individual exposure, the EEN signal represents the channel with the longest exposure
time
For one-push white balance, both shutter gain (AH) and gain( AW) are effective.
Note: EEN uses channel with the largest exposure value

The following is not a complete list. Please refer to Chapter 8, Serial Communication and Command List, for the details.
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 sets a target luminance level when command AR is activated. Settings: 0 to 1023 (for 40-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 sets the reset mode to be used
Settings 0: OFF
1: Auto Reset 2: Auto Interval Factory default is 0 (off).
1. Auto Reset Mode
In No Shutter External mode, when a trigger pulse does not occur after more than 52 ms, and the first trigger pulse is input after this absence, the video signal which was exposed during the trigger absence is output. If Auto Reset Mode is set to ON, the video, LVAL and DVAL during the trigger absence are not output and when the second trigger is input, the video, LVAL and DVAL are output again.

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-to­green channel difference are calculated separately. Then the exposure times 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

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 CMOS 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.

4. Caution when mounting the camera
When you mount the camera on your system, please make sure to use screws of the recommended length described in the following drawing. Longer screws may cause serious damage to the PCB inside the camera.
5. Exportation
When exporting this product, please follow the export regulation of your own country.
