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 .
For camera revision history, please contact your local JAI distributor

*1) Note: Rear protrusion on M52 mount lens must be less than 13mm.
F mount is also available. Rear protrusion for F mount lens is the same as M52 mount.
*2) Note: When a Camera LinkTM cable is connected to the camera, please do not excessively tighten
screws by using a driver. The Camera Link receptacle on the camera might be damaged.
For security, the strength to tighten screws is less than 0.291 Newton meter (Nm).
Tightening by hand is sufficient in order to achieve this.
*3) Note: The depth of mounting hole is 5 mm. If the longer screws than 5 mm are used, they may
damage the circuit board inside.

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.

6.2Key functions
Important note:
LQ-201CL has many functions explained in this chapter. In order to use these functions
properly and to get proper image, please follow the procedure described below.
Setting procedure:
1. Set the shutter and line rate
2. Set the master gain (refer to the chapter 6.3.5 for the details)
3. Set the white balance (refer to the chapter 6.3.4 for the details)
4. Activate DSNU compensation (refer to the chapter 6.3.9 for the details)
5. Activate PRNU compensation (refer to the chapter 6.3.8 for the details)
6. Activate the shading compensation (refer to the chapter 6.3.10 for the details)
After completing the above, adjust black level, lateral chromatic aberration and knee
adjustments. For these adjustments, there is no specific order required.

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. The serial interface of the 12-pin or Camera Link interface cannot be
used at the same time. The selection of the communication interface can be done via the DIP switch
located on the rear panel. (Refer to Chapter 4.2)

6.2.3 EEN (Exposure Enable) function
This function outputs the timing for image accumulation in all operating modes except test pattern
output. The output can be through both the 12-pin and Camera Link connectors. The polarity of this
output is negative from the 12-pin connector and positive from the Camera Link connector. These
polarities cannot be changed. The following drawing shows the output through Camera Link.
Fig.12 EEN function
6.2.4 White balance
In this function, the green channel video level is used as the reference. Red and blue channel levels
are adjusted to match with that of the green channel.
There are two ways to adjust white balance: one is gain white balance and the other is shutter
white balance.
