  • Page 15: Functions And Operation

    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 photodiodes (active pixels). The transfer gate controls the transfer of charge from photodiodes to the shift register.

  • Page 16: Operating Mode

    Sensor layout 6.2. Operating mode The LQ-050CL 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 17: No-Shutter Mode With Internal Trigger

    LQ-050CL 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 19: No-Shutter Mode With External Trigger

    LQ-050CL 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.

    LQ-050CL  If using individual exposure, the EEN signal represents the channel with the longest exposure time  The longest shutter operation is the same as the set trigger interval.  If one-push auto white balance is used, using the shutter (command AH) or using the gain (command AW) depends on applications.

  • Page 22: Pulse Width Control (Pwc) Mode

    LQ-050CL  If using individual exposure, the EEN signal represents the channel with the longest exposure time  The minimum trigger interval is 14.2μs.  If one-push auto white balance is used, using the shutter (command AH) or using the gain (Command AW) depends on applications.

    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.

  • Page 26: Command Ah - Activate One-Push Auto White Balance (Awb) - Shutter

    LQ-050CL 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 27: Command Bi - Binning (Horizontal Only)

    “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.

    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.

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

  • Page 32: Command Pgc - Enable Flat-Field Correction (Pixel Gain)

    LQ-050CL 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 33: 7.26. Command Pgs - Request Status After Pixel Gain Correction

    LQ-050CL 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.
