    4.1 Image Acquisition 4.1.1 Readout Modes The MV2-D1280-640-CL-8 camera provides two different readout modes: Sequential readout Frame time is the sum of exposure time and readout time. Exposure time of the next image can only start if the readout time of the current image is finished.

    Figure 4.6: Timing in triggered simultaneous readout mode 4.1.3 Maximum Frame Rate The maximum frame rate depends on the exposure time, the readout scheme and the size of the image (see Region of Interest, Section 4.5.1). In most cases, simultaneous readout is the best choice for highest framerate.

    4.3.2 Grey Level Transformation (LUT) Grey level transformation is remapping of the grey level values of an input image to new values. The look-up table (LUT) is used to convert the greyscale value of each pixel in an image into another grey value. It is typically used to implement a transfer curve for contrast expansion.

    4.6 External Trigger An external trigger is an event that starts an exposure. The trigger signal is either generated on the frame grabber (soft-trigger) or comes from an external device such as a light barrier. If a trigger signal is applied to the camera before the earliest time for the next trigger, this trigger will be ignored.

    Hardware Interface 5.1 Connectors 5.1.1 CameraLink Connector The CameraLink cameras are interfaced to external components via • two CameraLink connectors, which are defined by the CameraLink standard as a 26 pin, 0.05" Mini Delta-Ribbon (MDR) connector to transmit configuration, image data and trigger.

  • Page 44: Trigger And Strobe Signals

    5 Hardware Interface 5.1.3 Trigger and Strobe Signals The power connector contains an external trigger input and a strobe output. The input voltage to the TRIGGER pin must not exceed +15V DC, to avoid damage to the internal optocoupler! In order to use the strobe output, the internal optocoupler must be powered with 5 .. 15 V DC. The STROBE signal is an open-collector output, therefore, the user must connect a pull-up resistor (see Table 5.1) to STROBE_VDD (5 ..

    5.3 Read-out Timing 5.3.1 Free running Mode Sequential readout timing By default, the camera is in free running mode and delivers images without any external control signals. The sensor is operated in sequential readout mode, which means that the sensor is read out after the exposure time. Then the sensor is reset, a new exposure starts and the readout of the image information begins again.

    5.4 Trigger 5.4.1 Trigger Modes The following sections show the timing diagram for the trigger modes. The signal ExSync denotes the trigger signal that is provided either by the interface trigger or the I/O trigger (see Section 4.6). The other signals are explained in Table 5.4. Camera-controlled Exposure In the camera-controlled trigger mode, the exposure is defined by the camera and is configurable by software.
  • Page 52 5 Hardware Interface Level-controlled Exposure In the level-controlled trigger mode, the exposure time is defined by the pulse width of the external trigger signal. For an active high trigger signal, the image acquisition begins with the rising edge and stops with the falling edge of the external trigger signal. Then the image is read out.

  • Page 53: Trigger Delay

    5.4.2 Trigger Delay The total delay between the trigger edge and the camera exposure consists of the delay in the frame grabber and the camera (Fig. 5.12). Usually, the delay in the frame grabber is relatively large to avoid accidental triggers caused by voltage spikes (see Fig. 5.13). The trigger can also be delayed by the property Trigger.Delay.
  • Page 54 5 Hardware Interface For the delay in the frame grabber, please ask your frame grabber manufacturer. The camera delay consists of a constant trigger delay and a variable delay (jitter).
