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.
Various SVCam models are supporting adjustable lenses. Focus and iris of the lens can be controlled from within the camera GenICam tree. A special Y-cable might be required, contact sales@svs-vistek.com. The following variable lens types are currently supported: MFT lenses (in Tracer series) have full support of lens focus, iris and zoom.
Disadvantages of liquid lenses Limited resolution High chromatic aberration Any acceleration (gravitational as well as acceleration from move- ment) might increase spherical aberration as long as the force is work- ing (will disappear if force has ceased within several 10ms) 3.3.2 Use of Canon lenses We are supporting Canon EF lenses.

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 This section covers basic functionality of area sensor cameras.
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 sig- nal of individual or binned pixels before the ADC. Referring to photography adding gain corresponds to increasing ISO.
of the sensor will be used only internally to calibrate sensor values (“Dark pixels”). The amount of dark current in these areas is used to adjust the offset (see "Offset" below). For calculating image sizes, the maximum camera resolution is determining maximum image resolution, refer to the specifications of the camera model).
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.
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"...
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...
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.
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...
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.

interface). 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 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.
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 structures or as brightness instabilities.
Maximum frame rate might depend on: Pixel clock Image size Tap structure Data transport limitation Processing time 6.1.13 Auto exposure Auto Luminance or auto exposure automatically calculates and adjusts exposure time and gain, frame-by-frame. The auto exposure or automatic luminance control of the camera signal is a combination of an automatic adjustment of the camera exposure time (electronic shutter) and the gain.
6.1.14 Acquisition and processing time The camera has to read the sensor, process the data to a valid image and trans- fer 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 42
INFO Depending on camera model, different bit depths are supported. Packed format Some camera models support “packed” bitformats. Instead of using 16 bit per pixel (and transferring a lot of zeroes), 2 bytes contain more information than only 1 pixel. For example, in the image above, “Mono12Packed”...
Page 43
8-bit mode sensor pixel size is 50% faster, but the (bit-cut-off) reduced full well capacity also results in a higher noise percentage. To use the full dynamic range of the sensor, the sensor must be read out 12 bit, the transmission can then be done with (reduced) 8 or 12 bit, as required.
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.
Page 45
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. Before doing shad- ing correction, make sure your lens is clean and in perfect condition.
Page 46
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 47
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.
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 49
Fig.: 6-20: Illustration of a defect pixel Procedure of pixel correction SVCapture is the tool to generate pixel correction maps. The pixel correction assistant provides everything to create, load, enable and restore defect pixel creation maps. Defect pixel correction is possible with certain models only. See camera specs whether your model does support this.

6.2.4 Look-up table The look-up table feature (LUT) lets the user define certain values to every bit value that comes from the ADC. To visualize a LUT a curve diagram can be used, similar to the diagrams used in photo editing software.

Historically gamma correction was used to correct the illumination behavior of CRT displays, by compensating brightness-to-voltage with a gamma value between 1,8 up to 2,55. The gamma algorithms for correction can simplify resolution shifting as shown seen below. Input & output signal range from 0 to 1 Gamma Output-signal = Input-signal Fig.: 6-22: Several gamma curves comparable to a LUT...
6.2.5 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.: 6-23: 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.
6.2.6 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.
Fig.: 6-25: 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.
6.2.8 Temperature sensor A temperature sensor is installed on the main board of the camera. To avoid overheating, the temperature is constantly monitored and read. Besides soft- ware monitoring, the camera indicates high temperature by a red flashing LED (see flashing LED codes). 6.2.9 Fan control The camera has a built-in fan that is set to automatic mode by default.
6.2.10 System clock frequency Default system clock frequency in almost every SVCam is set to 66.6 MHz. To validate your system frequency refer to: specifications. Using the system clock as reference of time, time settings can only be made in steps.
Reset to factory default User sets can be reset to factory settings. This is a two-step process. First, the factory settings must be loaded: Afterwards this factory default user set must be saved again as user set (in the example below, user set 2 is overwritten with the factory settings). 6.2.12 Particle Image Velocimetry Cameras operated in Particle Image Velocimetry (PIV) mode will generate 2...
Page 61
Fig.: 6-28: Sequence of exposure in PIV mode For avoiding different image brightness as a result of different exposure times of both images, it is recommended to work in darkness and control image bright- ness via strobe light intensity and strobe duration. Gap adjustment is done by positioning strobe in the exposure windows.
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.
NOTICE All modfications in the GenICam tree will have immediate effect. 6.3.2 Assigning I/O Lines – IOMUX The IOMUX is best described as a switch matrix. It connects inputs, and outputs with the various functions of SVCam I/O. It also allows combining inputs with Boolean arguments.

6.3.3 During Pulse Width Modulation (PWM), a duty cycle is modulated by a fixed fre- quency square wave. This describes the ratio of ON to OFF as duty factor or duty ratio. Why PWM? Pulse width modulation is an extremely efficient way (in terms of power dis- sipation) to provide/regulate electrical power to consumers as long as they do not need uninterrupted supply (such as diodes or LEDs).

6.3.4 LED strobe control The SVCam 4I/O concept contains an integrated strobe controller. Its controls are integrated into the GenICam tree. With LED lights attached to the outputs, this enables the user to control the light without external devices. Being con- trolled via GenICam, any GenICam-compliant 3 party software is able to con- trol the light as well.
