    (the inverse of line rate). This also allows a fixed exposure time, independent of the line rate. In the LQ-200CL the exposure time can be set individually for all four channels.

  • Page 14: Operating Mode

    LQ-200CL 6.2. Operating mode The LQ-200CL has three operating modes. They are No-Shutter mode, Shutter-Select mode and PWC (Pulse Width Control) mode. The following chapters explain the details of these three modes. The output detail is shown below and is common with all modes.

  • Page 15: No-Shutter Mode With Internal Trigger

    LQ-200CL 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 = 1/line rate).

  • Page 16: Shutter Mode With External Trigger

    LQ-200CL 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.

  • Page 17: Shutter-Select Mode With Internal Trigger

    LQ-200CL 6.2.3 Shutter-Select mode with internal trigger 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.

  • Page 18: Shutter-Select Mode With External Trigger

    LQ-200CL 6.2.4 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.

  • Page 19: Pulse Width Control (Pwc) Mode

    LQ-200CL 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.

    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-200CL automatically returns to continuous operation with the line rate of 52.5μs. In this time, the camera operates by the internal trigger, and if the trigger is input, the video is immediately output.

  • Page 22: Command Ah - Activate One-Push Auto White Balance (Awb) - Shutter

    LQ-200CL 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.

  • Page 23: Command Bi - Binning (Horizontal Only)

    0 LSB to 64 (16) LSB. The number in parenthesis is valid for 32-bit output. The LQ-200CL 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.

  • Page 24: Command Ei - Interlocked R, G, B & Nir Exposure

    LQ-200CL 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.

     It is recommended to use 52.5μs to 2ms of line rate because the black level is stable in this range. 7.18 Command LUTC - LUT Control The LQ-200CL has an internal LUT(Look Up Table) for setting gamma. Command LUTC selects gamma OFF, Gamma 0.45 or LUT. Settings: 0 = Off 1 = 0.45...

    LQ-200CL 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. Before correction: dark signal non-uniformity from pixel to pixel...

  • Page 28: Command Pgc - Enable Flat-Field Correction (Pixel Gain)

    LQ-200CL 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.

  • Page 29: 7.26. Command Pgs - Request Status After Pixel Gain Correction

    LQ-200CL Before correction: Non-uniform response from Multiply pixel to pixel Factor Average < 1 Multiply Factor > 1 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.

    LQ-200CL 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.
