The FXO camera series The FXO is a camera series designed for high-end machine vision with a C-mount connection. Only Sony image sensors with excellent optical performance and high bandwidth are used in the FXO. Advanced electronic circuitry, an excellent tem- perature management and low power dissipation make the basis for optimal per- formance of even the most demanding image sensors.
4I/O adds light and functionality Fig. 2-1: 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 indi- vidually 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.
Canon EF/EF-S lens Focus and iris control is supported. Use Canon lenses with machine vision applications. The SVCam-EF lens adapter can be acquired from SVS-VISTEK. INFO Lens control (except MFT) will make use of the serial ports of the Hirose connector.

This chapter covers features of SVCam cameras. Not every feature might be sup- ported by your specific camera model. For information about the features of your spe- cific model, refer to the specifications area of our website with your exact model. https://www.svs-vistek.com/en/industrial-cameras/svs-svcam-searchresult.php 5.1 Basic features 5.1.1 ...
Fig. 5-1: Noise caused by too much gain Auto gain For automatic adjustment of gain refer to auto exposure (see "Auto exposure" on page 35). 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 preferable to use fixed gain values instead and modify exposure with exposure time.
Fig. 5-2: Dark noise cut off by the offset Most noise is proportional to temperature. To spare you regulating the offset every time the temperature changes. A precedent offset is set by the camera itself. It ref- erences certain pixels that never were exposed to light as black. So the offset will be set dynamically and conditioned to external influences.
Page 22
Note that about half of the pixels are green, a quarter red and a quarter blue. This is due to the maximum sensitivity of the human eye at about 550 nm (green). De-Bay- ering is not done in the camera, it must be done in the client software . Not all sensors have the same sequence of color.
1. When using SVCapture 2, select Guru as Feature Mode. 2. Select BalanceWhiteAuto in Analog Control in the GenICam feature tree. The White Balance “Continuous” mode is only recommended in a slow triggered mode. Usually, it is sufficient to perform a white balance once with the given lighting.
Fig. 5-6: Vertical flip 5.1.6 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. INFO Binning is only used with monochrome CCD sensors. On CMOS sensors, binning will not affect image quality.

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. 5-12: 2x2 binning 5.1.7 Decimation For reducing width or height of an image, decimation can be used. Columns or rows can be ignored.
With your SVCam, the GenICam tree does have some hardware related extensions, especially in the I/O sector. See the Quick guide install for a short introduction 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 for trigger is Input1. 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 31
Fig. 5-16: Mode 2: External trigger with programmable exposure time (non overlap) Exposure time can be changed during operation. No frame is distorted during switch- ing time. If the configuration is saved to the EEPROM, the set exposure time will remain also when power is removed.
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 situations.
Page 33
Fig. 5-21: setup of global reset release mode in GenICam tree Benefits All pixel reset all lines same time Light integration starts with same point of time for each line All lines stop integration at different time ...
When flashing in global reset mode, the flash time will define the exposure time. Thus, an very time-stable flash control is essential. Fig. 5-22: Flash control with global reset release In Global Reset Mode flash is starting together with exposure, all CMOS lines are sensitive to light.
Maximum frame rate might depend on: Pixel clock Image size Tap structure Data transport limitation Processing time 5.1.13 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 com- bination of an automatic adjustment of the camera exposure time (electronic shutter) and the gain.
5.1.15 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 rep- resented. Bit depth defines the maximum unique colors or gray levels in an image. bit depth No of gray values = 2 All SVCam models support 8-bit format.
The final bit depth exported by the camera (camera readout) is adjusted with pixel size. Bit depth and brightness with Sony Gen 4 sensors The FXO series (XGE / CXP) shows different brightness when switching between 8-bit and 12-bit mode (SensorPixelSize). If you read sensor 8-bit, the upper 4 bits of the sensor range are cut off.
5.2.2 Shading correction Overview The interactions between objects, illumination, and the camera lens might lead to a non-uniform flat-field in brightness. Shading describes the non-uniformity of bright- ness from one edge to the other or center towards edge(s). Fig. 5-25: Original and shading corrected image This shading can be caused by non-uniform illumination, non-uniform camera sens- itivity, vignetting of the lens, or even dirt and dust on glass surfaces (lens).
Page 39
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 cal- culated. The resulting map can be uploaded into the camera and will compensate for any shading, lens-based or based on illumination.
Page 40
First, shading reference images have to be taken with shading correction disabled (use 16 images minimum). Save it on disk. Use std .bmp files here, if possible with more than 8 bit. 1. Run shading assistant->Generate Map Fig. 5-26: Shading control disabled ...
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 fact- ory default. Under challenging conditions or high temperature environments defect pixel beha- vior might change.
Page 42
A factory created defect map (SVS map), defying known defects, is stored in the camera. A custom defect map can be created by the user. A simple *.txt file with coordin- ates must be created. The user must locate the pixel defects manually. ...
Page 43
For easy image processing, it is recommended to have pixel correction activated Pixel correction maps can be saved and loaded The std factory map can be selected any time Generate your own custom map Select your own defect pixel map The procedure to create a std map is pretty straight forward.

6. Add a “Bright Image”. 7. Select Generate map. 8. Observe how many defect pixel were detected in the “Defect Pixel Count”. 9. Select Upload map to camera. 5.2.4 Look-up table The look-up table feature (LUT) lets the user define certain values to every bit value that comes from the ADC.
Page 46
Fig. 5-28: Custom LUT adding contrast to the mid-tones INFO LUT implementation reduces bit depth from 12 bit to 8 bit on the output. Gamma correction Using the look-up table makes is also possible to implement a logarithmic correction. This is commonly called “gamma correction”. 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.
Page 47
Fig. 5-29: Several gamma curves comparable to a LUT Gamma values less than 1.0 map darker image values into a wider ranger. Gamma values greater than 1.0 do the same for brighter values. INFO Gamma algorithm is just a way to generate a LUT. It is not implemented in the cam- era directly.
Page 48
Fig. 5-30: Several gamma curves comparable to a LUT Gamma values less than 1.0 map darker image values into a wider ranger. Gamma values greater than 1.0 do the same for brighter values. INFO Gamma algorithm is just a way to generate a LUT. It is not implemented in the cam- era directly.
5.2.5 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. 5-31: 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 50
The fundamental signals are: Line Valid: LVAL Frame Valid: FVAL For triggered modes: trigger input Triggered mode (pulse width) External trigger and pulse-width controlled exposure time. In this mode the camera is waiting for an external trigger, which starts integration and readout. Exposure time can be varied using the length of the trigger pulse (rising edge starts integration time, falling edge terminates the integration time and starts frame read out).
INFO Software trigger can be influenced by jitter. Avoid software trigger when using time sensitive applications. 5.2.7 Read-out control Read-out control defines a delay between exposure and data transfer. Read-out con- trol 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.

Term Definition Bayer Pattern A Bayer filter mosaic or pattern is a color filter array (CFA) depos- ited onto the surface of a CCD or CMOS sensor for capturing RGB color images. The filter mosaic has a defied sequence of red, green and blue pixels such that the captured image can be transported as a monochrome image to the host (using less bandwidth), after which the RGB information is recombined in a computer algorithm.
