  • Page 42: Decimation (Monochrome Cameras)

    5 Functionality 5.1.4 Decimation (monochrome cameras) Decimation reduces the number of pixels in y-direction. Decimation in y-direction transfers every n row only and directly results in reduced read-out time and higher frame rate respectively. Decimation can also be used together with ROI or MROI. In this case every ROI should have a height that is a multiple of the decimation setting.

  • Page 45: Decimation (Colour Cameras)

    5.1.5 Decimation (colour cameras) Decimation reduces the number of pixels in y-direction by skipping rows. Decimation in colour cameras is slightly different from the monochrome cameras, because the order of the Bayer pattern must be maintained. Beginning from the first row, always two rows are read out and then an even number of rows is skipped.

  • Page 46: Binning

    5 Functionality 5.1.6 Binning Description Binning sums the pixels in subsequent columns and rows, according to the binning configuration. The result is then divided by the number of binned pixels. The binning feature will result in images with lower resolution but significantly higher SNR. For instance, 2x2 binning will result in roughly twice the SNR (in bright areas of the image).
  • Page 47 Property Type Description BinningHorizontal Integer Number of pixels combined in binning in horizontal direction. BinningVertical Integer Number of pixels combined in binning in vertical direction. Binning_Bitshift Integer Additional left bitshift after binning (overflow is ignored) PixelFormat Enumeration If BinningHorizontal or BinningVertical is set to a value bigger than 1 then the Mono16 (16 bit) pixel format is available (not available in DR1 models).

  • Page 48: Maximal Frame Rate

    5 Functionality 5.1.7 Maximal Frame Rate The maximal frame rate of the camera depends on the camera settings. The following factors influence the maximal frame rate (see also Table 5.1): • The length of the exposure time: A shorter exposure time can lead to an increase in the maximal frame rate.
  • Page 49 Simultaneous Read out Timing 1 The exposure time is smaller than the read out time in this timing (see Fig. 5.13). Exposure is started during the sensor read out of the previous frame. The maximal frame rate is in this case (values are given in Table 5.6 and Table 5.7): MaxFrameRate = 1 / (ReadoutTime + TExpDel + TReadoutDel) To avoid a sensor artifact, the exposure must start at a fixed position from the start of the read out of one row.

  • Page 50: Trigger And Strobe

    5 Functionality Sequential Read out Timing In this timing the exposure is started after the read out of the previous frame (see Fig. 5.15). The maximal frame rate is in this case (values are given in Table 5.6): MaxFrameRate = 1 / (ExposureTime + TReadoutDel + ReadoutTime) The ReadoutTime is the height of the ROI multiplied by the read out time of one row (see Table 5.6).
  • Page 51 Free running The trigger is generated internally by the camera. Exposure starts immediately after the camera is ready and the maximal possible frame rate is attained, if AcquisitionFrameRateEnable is disabled. Settings for free running trigger mode: TriggerMode = Off. In Constant Frame Rate mode (AcquisitionFrameRateEnable = True), exposure starts after a user-specified time has elapsed from the previous exposure start so that the resulting frame rate is equal to the value of AcquisitionFrameRate.

  • Page 52: Trigger And Acquisitionmode

    5 Functionality Figure 5.17: Trigger Inputs - Multiple GigE solution 5.2.3 Trigger and AcquisitionMode The relationship between AcquisitionMode and TriggerMode is shown in Table 5.8. When TriggerMode=Off, then the frame rate depends on the AcquisitionFrameRateEnable property (see also under Free running in Section 5.2.2). The ContinuousRecording and ContinousReadout modes can be used if more than one camera is connected to the same network and need to shoot images si- multaneously.
  • Page 53 AcquisitionMode TriggerMode After the command AcquisitionStart is executed: Continuous Camera is in free-running mode. Acquisition can be stopped by executing AcquisitionStop command. Continuous Camera is ready to accept triggers according to the TriggerSource property. Acquisition and trigger acceptance can be stopped by executing AcquisitionStop command.

  • Page 54: Exposure Time Control

    5 Functionality 5.2.4 Exposure Time Control Depending on the trigger mode, the exposure time can be determined either by the camera or by the trigger signal itself: Camera-controlled Exposure time In this trigger mode the exposure time is defined by the camera.
  • Page 55 results then from the synchronous design of the FPGA state machines and from to trigger offset requirement to start an exposure at a fixed point from the start of the read out of a row. The exposure time t is controlled with an internal exposure time controller. exposure The trigger pulse from the internal camera control starts also the strobe control state machines.

  • Page 56: Trigger Delay

    5 Functionality The falling edge of the trigger pulse is delayed by the time t which results from the d iso input signal isolator. This signal is clocked into the FPGA which leads to a jitter of t . The pulse is jitter then delayed by t by the user defined value which can be configured via camera...

  • Page 60: A/B Trigger For Incremental Encoder

    5 Functionality 5.2.9 A/B Trigger for Incremental Encoder An incremental encoder with A/B outputs can be used to synchronize the camera triggers to the speed of a conveyor belt. These A/B outputs can be directly connected to the camera and appropriate triggers are generated inside the camera.
  • Page 61 There is a bug in the single A/B trigger mode in some camera revisions (see Ap- pendix B, A/B Trigger Bug). In this case when the encoder position moves back and forth by a small amount, the EncoderCounter is incremented and the decre- ment is sometimes omitted, leading to a wrong EncoderPosition indication in the camera.
  • Page 62 5 Functionality A/B Trigger Debounce A debouncing logic can be enabled by setting ABTriggerDeBounce=True. It is implemented with a watermark value of the EncoderCounter (see Fig. 5.24). Suppose ABTriggerDirection=fwd, then the watermark value is increased with the increments of the EncoderCounter. If EncoderCounter decreases, e.g.
  • Page 63 A/B Trigger Divider if ABTriggerDivider>1 then not all internally generated triggers are applied to the camera logic. E.g.

  • Page 64: Missed Trigger Counters

    5 Functionality By default the Encoder Position is only generated when TriggerMode=On and TriggerSource=ABTrigger. When the property ABTriggerCountAlways=True, then the Encoder Position is generated regardless of the trigger mode. 5.2.10 Missed Trigger Counters The missed trigger counters are important tools to make sure that the frequency of an external trigger can be processed by the camera.
  • Page 65 The setting Counter_ResetCounterMode=Continuous resets the counters on every occurrence of an active edge of the reset source without the requirement to arm the device first. This setting is suited if the reset source signal is different than the camera trigger. The active edge of the reset input can be set by the property Counter_ResetCounterSourceInvert.

  • Page 66: High Dynamic Range (Multiple Slope) Mode

    5 Functionality 5.3 High Dynamic Range (multiple slope) Mode The High Dynamic Range (HDR) mode is a special integration mode that increases the dynamic range of the pixels, and thus avoids the saturation of the pixels in many cases. The HDR mode is also called multiple slope mode or piecewise linear mode.

  • Page 76: Crosshairs

    5 Functionality 5.7 Crosshairs 5.7.1 Functionality The crosshairs inserts a vertical and horizontal line into the image. The width of these lines is one pixel. The grey level is defined by a 12 bit value (0 means black, 4095 means white). This allows to set any grey level to get the maximum contrast depending on the acquired image.
  • Page 77 The x- and y-positon is absolute to the sensor pixel matrix. It is independent on the ROI, MROI or decimation configurations. Figure Fig. 5.42 shows two situations of the crosshairs configuration. The same MROI settings is used in both situations. The crosshairs however is set differently.

  • Page 78: Image Information And Status Line

    5 Functionality 5.8 Image Information and Status Line There are camera properties available that give information about the acquired images, such as an image counter, average image value and the number of missed trigger signals. These properties can be queried by software. Alternatively, a status line within the image data can be switched on that contains all the available image information.

  • Page 79: Status Line

    5.8.2 Status Line If enabled, the status line replaces the last row of the image with camera status information. Every parameter is coded into fields of 4 pixels (LSB first) and uses the lower 8 bits of the pixel value, so that the total size of a parameter field is 32 bit (see Fig. 5.43). The assignment of the parameters to the fields is listed in Table 5.12.

  • Page 82: Test Images

    5 Functionality 5.9 Test Images Test images are generated in the camera FPGA, independent of the image sensor. They can be used to check the transmission path from the camera to the acquisition software. Independent from the configured grey level resolution, every possible grey level appears the same number of times in a test image.

  • Page 95: I/O Wiring

    6.5.6 I/O Wiring The Photonfocus cameras include electrically isolated inputs and outputs. Take great care when wiring trigger and strobe signals to the camera, specially over big distances (a few meters) and in noisy environments. Improper wiring can introduce ground loops which lead to malfunction of triggers and strobes.
  • Page 96 6 Hardware Interface Common Grounds with Star Wiring Ground loops can be avoided using "star wiring", i.e. the wiring of power and ground connections originate from one "star point" which is typically a power supply. Fig. 6.14 shows a schematic of the star-wiring concept. Fig.
  • Page 97 Fig. 6.16 shows an example of how to connect a flash light and a trigger source to the camera using star-wiring. The trigger in this example is generated from a light barrier.
