  • Page 23: Gain

    6.1.1 Gain Setting gain above 0 dB (default) is a way to boost the signal coming from the sensor. Especially useful for low light conditions. Setting gain amplifies the signal of individual or binned pixels before the ADC. Referring to photography adding gain corresponds to increasing ISO.

  • Page 24: Offset

    The amount of dark current in these areas is used to adjust the offset (see "Off- set" below). For calculating image sizes, the maximum camera resolution is determining max- imum image resolution, refer to the specifications of the camera model). 6.1.3 Offset For physical reasons the output of a sensor will never be zero, even the camera is...

  • Page 25: Color

    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: CCD with Bayer pattern The camera sensor has a color mosaic filter called “Bayer” filter pattern named after the person who invented it.

  • Page 27: Binning

    Fig.: 6-6: Vertical flip 6.1.6 Binning Binning provides a way to enhance dynamic range, but at the cost of lower res- olution. Binning combines electron charges from neighboring pixels directly on the chip, before readout. Binning is only used with monochrome CCD Sensors. For reducing resolution on color sensors refer to "Decimation"...

  • Page 28: Decimation

    Horizontal binning Accumulates horizontal pixels. Fig.: 6-8: Horizontal binning 2×2 Binning A combination of horizontal and vertical binning. When DVAL signal is enabled only every third pixel in horizontal direction is grabbed. Fig.: 6-9: 2x2 binning 6.1.7 Decimation For reducing width or height of an image, decimation can be used. Columns or rows can be ignored.
  • Page 29 Fig.: 6-10: Horizontal decimation Fig.: 6-11: Vertical decimation Decimation on color sensors The Bayer pattern color information is preserved with 1/3 horizontal and vertical resolution. The frame readout speed increases approx. by factor 2.5. Fig.: 6-12: Decimation on color sensors 6 Feature description...

  • Page 30: Genicam

    With your SVCam, the GenICam tree does have some hardware related exten- sions, especially in the I/O sector. See the Quick guide install for a short intro- duction into the SVS-Vistek GenICam tree. The GenICam properties are organized in views. The recommended way to view and adjust is by using SVCapture.

  • Page 31: 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 32 Exposure time can be changed during operation. No frame is distorted during switching time. If the configuration is saved to the EEPROM, the set exposure time will remain also when power is removed. Details of external trigger mode Diagrams below are equivalent for CCD and CMOS technique. 6 Feature description...
  • Page 33 6 Feature description...

  • Page 34: 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. Especially flashing and moving objects might need more attention with rolling shutter.
  • Page 35 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 Flash strobe on whole exposure time...
  • Page 36 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 37 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 38 Global Reset Release Mode Global reset release mode is a special mode to operate rolling shutter sensors. 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 situations.

  • Page 39: Exposure

    Fig.: 6-16: strobe control in global reset mode In Global Reset Mode flash is starting together with exposure, all CMOS lines are sensitive to light. Flash time has to be shorter than exposure time. Exposure time is determined by flash time. INFO Strobe control jitter might be visible in the image as brightness instabilities.

  • Page 40: Auto Exposure

    Limitations exo183 on exposure time In general, the SVS-specific camera design permits frame rates close to this for- mula: Fps_max = 1 / exposure time The exo183 has some specific sensor properties. Most important, due to its sensor design it comes with an additional readout time of about 56 ms. Thus, the maximum exo183 frame rate calculates as follows (as long not restricted by inter- face speed): Fps_max =1 / ( exposure time + 56 ms)
  • Page 41 6 Feature description...

  • Page 42: Acquisition And Processing Time

    6.1.14 Acquisition and processing time The camera has to read the sensor, process the data to a valid image and transfer this to the host computer. Some of these tasks are done in parallel. This implies the data transfer does not end immediately after end of exposure, as the image has to be processed and transferred after exposure.

  • Page 43: Bit Depth

    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. Bit depth defines the max- imum unique colors or gray levels in an image. bit depth No of gray values = 2 All SVCam models support 8-bit format.
  • Page 44 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. 6 Feature description...

  • Page 45: Roi / Aoi

    6.1.16 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.: 6-18: 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.

(B) Grid polarizers with different grid orientations result in linear polarized light with orientations perpendicular to the grid orientation, respectively.

  • Page 49: Camera Features

    Conveniently, the polarization angle and the degree of linear polarization are easily computed from the Stokes parameters Examination of these values provides an imaging contrast enhancement in a mul- titude of applications compared to standard camera imaging, as shown in the fol- lowing application examples.

  • Page 50: Shading Correction

    White balance gets much more difficult. Contrast is lower. INFO SVS-VISTEK recommends IR cut filter for high demands on sharpness with monochrome or color sensors. Spectral impact of IR cut filters IR cut filter do influence the spectral sensitivity of the sensor. The spectral graph below shows the wavelength relative impact of the SVS-VISTEK standard filter.
  • Page 51 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-uniform image regardless of the reasons of the non-uniformity.
  • Page 52 NOTICE Shading correction is possible with certain models only. See camera specs whether your model does support this. In case your camera is not supporting, the assistant will not be selectable. First, shading reference images have to be taken with shading correction disabled (use 16 images minimum).
