  • Page 10: Operation And Functions

    5.1 Introduction 5.1.1 Image sensor The SW-2000M-CL-65 is built around a high performance CMOS line scan image sensor, which converts the light collected by each pixel into electrical charge. The amount of charge generated in each of the individual pixels is basically directly proportional to the amount of light they receive.

  • Page 11: Image Processing

    SW-2000M-CL-65 5.1.2 Image processing The output data from the imager is buffered for further processing to be then finally sent out of the camera via the Camera Link interface. The processing chain is controlled by user accessible commands. The DSNU corrector is calibrated individually for each camera at the factory and always in use with fixed settings.

  • Page 12: Operating Modes

    5.5 Test Pattern Generator The SW-2000M-CL-65 can send out five, defined test patterns instead of the real imaged lines for purposes like interfacing and problem analysis. The patterns replace the image data and can thus be used also to test the following blocks.

    Shading correction is replaced by FFC, which operates assuming a fixed dark reference level and includes the PRNU correction. The FFC unit of SW-2000M-CL-65 offers the possibility to scale the pixel values by factors that are calculated by imaging a calibration target in order to produce a uniform (flat) response under the same conditions as where the calibration routine was run.

  • Page 14: Camera Link Interface

    SW-2000M-CL-65 5.10 Camera Link interface One Camera Link connector is available to connect standard Base Configuration interface devices (frame grabber boards, etc.) to receive image data, to control the scan rate and exposure of the camera, as well as to communicate via the Camera Link serial channel.

  • Page 15: Firmware Updates

    SW-2000M-CL-65 5.12 Firmware updates It is possible to update or change the camera firmware without opening the housing. New code is loaded in via the Ethernet port and with help of web browser user interface. There are two kinds of firmware updates: MCU and FPGA. The MCU (microcontroller unit) updates affect the user interface and high level features of the camera, while the FPGA (field-programmable gate array) updates provide enhancements for low level or hardware related functions.

  • Page 26: Group B: Commands Affecting Exposure

    SW-2000M-CL-65 Group B: Commands affecting exposure SENSOR 7.2.1 – selects the sensor mode The sensor has two possibilities of collecting the light generated charge. The default setting uses the larger well size for a wider dynamic range and a better signal to noise ratio, which results in more valid bits.

  • Page 27: Line Ctrl - Exposure Control

    SW-2000M-CL-65 LINE CTRL - Exposure Control 7.2.3 The camera has three exposure control modes: internal, external and mixed, which is a combined mode of the first two. The start and length of each line, as well as the time that the light is collected within each line period, follow the same principles regardless of the selected mode.
  • Page 28 SW-2000M-CL-65 time as the line period ends. The Internal exposure mode cannot be synchronized to an external event. If external synchronization is needed then External or Mixed mode must be selected for Exposure Control. 7.2.3.2 External exposure control (command: LINE CTRL EXT) The line period and integration time are controlled externally by the CC1 and CC2 input signals at the Camera Link connector.
  • Page 29 SW-2000M-CL-65 7.2.3.3 Mixed mode exposure control (command: LINE CTRL MIX) The line period is now the time between two consecutive rising edges of the CC1 input signal at the Camera Link connector. The integration time is controlled internally by the command LINE IT. The syntax for LINE IT gives the ability to set the integration time in microseconds or in percentage of maximum possible integration time.

  • Page 30: Line It - Integration Time

    SW-2000M-CL-65 LINE IT integration time 7.2.4 This command is used to control the integration time (effective exposure time) for each line. The timing can be specified either as an absolute time in microseconds, or as percentage of the line period. The integration time given as percentage of the line interval is recalculated automatically when the line rate changes.
