    4I/O adds light and functionality Fig.: 3-1: Illustration of 4I/O concept of switching LEDs Your SVS-Vistek camera is equipped with the innovative 4I/O-interface allowing full light control, replacing external strobe controllers. Each of the outputs can be individually configured and managed using pulse width modulation. With its high current output, the camera is able to drive LED lights directly without external light controller.

    This chapter covers features of SVCam cameras. Not every feature might be supported by your specific camera model. For information about the features of your specific model, please refer to the specifications area of our website with your exact model. https://www.svs-vistek.com/en/industrial-cameras/svs-svcam-searchresult.php Basic features 6.1.1 Gain Setting gain above 0 dB (default) is a way to boost the signal coming from the sensor.

    Auto gain For automatic adjustment of gain refer to auto exposure (see "Auto exposure" on page 44). When using auto-gain with steps of gain the noncontinuous gain adjustment might be visible in final image. Depending on your application it might be prefer- able to use fixed gain values instead and modify exposure with exposure time.

    6.1.4 Color Color cameras are identical to the monochrome versions. The color pixels are transferred in sequence from the camera, in the same manner as the mono- chrome, but considered as “raw”-format. Fig.: 6-3: Sensor with Bayer pattern The camera sensor has a color mosaic filter called “Bayer” filter pattern named after the person who invented it.

  • Page 38: Shutter Modes

    6.1.10 Shutter modes CCD and CMOS area cameras consist of pixels, ordered in lines and columns. All pixel are exposed to light and then read out to camera electronics. There is a difference of reading out the sensor between global and rolling shutter. Espe- cially flashing and moving objects might need more attention with rolling shut- ter.

Nonetheless, the maximum achievable frame rate with applied ROI will be the maximum frame rate of the sensor reading the full sensor area (internal full sensor speed), please refer to relating sensor specs. Artifacts All pixel show same artifacts Deformed image of moving objects Exposure with flash Fig.: 6-13: flash control with rolling shutter...
  • Page 40 Light control with rolling shutter As being said, not all sensor lines are sensitive to light at the same time. Make sure your light is ON as long any pixel are going to e exposed. An exo183xGE i.e. needs about 62ms of minimal scanning time. An exo183xCL i.e. needs about 120ms of minimal scanning time.
  • Page 41 Rolling shutter limitations Due to the principles of rolling shutter, some standard features of SVS-Vistek cameras are not applicable. External exposure control (expose while trigger signal active) does not make sense with rolling shutter ROI with rolling shutter: With rolling shutter the whole sensor has to be read out –...
  • Page 42 Global reset release mode is a special mode to operate rolling shutter sensors. With the exception of the hr120, all rolling shutter cameras from SVS-Vistek GmbH can be operated in Global Reset Release mode. Global reset release shows advantages when operating light sources in non-constant light situ- ations.

    Global reset release mode setup make sure of no external (constant) light source use flash only for object illumination set camera to global reset release mode start exposure time together with flash (flash strobe in darkness) When flashing in global reset mode, the flash time will define the exposure time. Thus, an very time-stable flash control is essential.

    image to next image will result in a swing of the control loop. Therefore it is not recommended to use the auto-luminance function in such cases. 6.1.15 Bit depth Values of brightness are internally represented by numbers. The number of bits for brightness representation is limiting the number of color values that can be represented.
  • Page 46 image quality, but the image needs to be unpacked (with an SVCam SDK func- tion, very fast) after image acquisition before the image can be processed. NOTICE Unpacking has to be done manually, this is not a GenTL function. Thus, image acquisition in packed formats won’t be supported by most 3 party software products.

    INFO As soon as the internal memory buffer is filled up, frames will be dropped. Due to this, SVS-Vistek cameras provide up to 512 MB image buffer memory. 6.2.2 Glass filter The camera is equipped with a glass filter for sensor protection reasons (dust).
  • Page 48 brightness from one edge to the other or center towards edge(s). Original and shading corrected image This shading can be caused by non-uniform illumination, non-uniform camera sensitivity, vignetting of the lens, or even dirt and dust on glass surfaces (lens). Shading correction is a procedure to create a flatfield image out of a non-uni- form image regardless of the reasons of the non-uniformity.
  • Page 49 How it works The tool will divide the image into squares of 16x16 pixel. Out of every 16x16 pixel cluster a set of shading values consisting of specific gain and offset per cluster is calculated. The resulting map can be uploaded into the camera and will compensate for any shading, lens-based or based on illumination.
  • Page 50 2. With SVCapture load these reference images. 3. See shading in the preview 4. Generate the shading map 5. Save map to disk. This file can be used in programmed environments via SDK as well. 6. Upload it to the camera and see the result. If lighting did not change from start of procedure, you should see a uniform image with enabled shading control.

  • Page 51: Defect Pixel Correction

    The amount of hot pixels is proportional to exposure time and temperature of the sensor. By default, all known defect pixels or clusters are corrected by SVS-VISTEK as a factory default. Under challenging conditions or high temperature environments defect pixel behaviour might change.

  • Page 58: Roi / Aoi

    6.2.6 ROI / AOI In partial scan mode or Area-Of-Interest (AOI) mode (or Region-Of-Interest (ROI) mode) only a certain region of the sensor will be read. Fig.: 6-22: AOI on area sensor Selecting an AOI will reduce the number of horizontal lines being read. This will reduce the amount of data to be transferred, thus increasing the maximum speed in terms of frames per second.

  • Page 59: Basic Capture Modes

    6.2.7 Basic capture modes The camera has 2 basic operation modes. Free run (timed) run: The camera will expose and deliver images on a fixed schedule. Triggered: The camera will wait for an external signal and start exposure after receiving the external trigger signal.
  • Page 60 Fig.: 6-24: Basic capture modes - triggered mode (pulse width with overlap) Exposure time of the next image can overlap with the frame readout of the cur- rent image (rising edge of trigger pulse occurs when FVAL is high). When this happens: the start of exposure time is synchronized to the falling edge of the LVAL signal.

  • Page 61: Trigger Modes

    Default input is Input1 for trigger. At the rising edge of the trigger the camera will initiate the exposure. The software provided by SVS-Vistek allows the user to set exposure time e.g. from 60 μs to 60 sec (camera type dependent).

  • Page 63: Read-Out Control

    6.2.9 Read-out control Read-out control defines a delay between exposure and data transfer. Read- out control is used to program a delay value (time) for the readout from the sensor. With more than one camera connected to a single computer, image acquisition and rendering can cause conflicts for data transfer, on CPU or bus system.

  • Page 64: Predefined Configurations (User Sets)
