The HR camera series Focusing on details The SVCam HR series is a series of industrial machine vision cameras fea- turing especially on very high image resolutions and interface high speed without compromising on image quality. Camera sensors and interfaces are built to deliver maximum sensor and interface bandwidth.
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 Global shutter The shutter is describing the functionality of exposing the light sensitive pixels of the sensor to light for a limited time.
Page 23
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.
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 –...
6.1.4 Exposure speed Frames per second, or frame rate describes the number of frames output per second (1/ frame time). Especially GigE and USB cameras cannot guarantee predictable maximum frame rates with heavy interface bus load. Maximum frame rate might depend on: Pixel clock Image size Tap structure...
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. 6.1.7 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.
add 6 dB double ISO value 6 dB 400 ISO 12 dB 800 ISO 18 dB 1600 ISO 24 dB 3200 ISO Table: 6-1: Table of dB and corresponding ISO value NOTICE Gain also amplifies the sensor’s noise. Therefore, gain should be last choice for increasing image brightness.
6.1.10 Offset For physical reasons the output of a sensor will never be zero, even the camera is placed in total darkness or simply closed. Always there will be noise or ran- domly appearing electrons that will be detected as a signal (dark noise: noise generated without light exposure).
6.1.11 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.: 6-5: Sensor with Bayer pattern The camera sensor has a color mosaic filter called “Bayer” filter pattern named after the person who invented it.
6.1.12 Flip image Images can be mirrored horizontally or vertically. Image flip is done inside the memory of the camera, therefore not increasing the CPU load of the PC. Fig.: 6-6: Original image Fig.: 6-7: Horizontal flip 6 Feature description...
Fig.: 6-8: Vertical flip 6.1.13 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.: 6-10: 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.: 6-11: 2x2 binning 6.1.14 Decimation For reducing width or height of an image, decimation can be used. Columns or rows can be ignored.
Page 33
Fig.: 6-12: Horizontal decimation Fig.: 6-13: 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.: 6-14: 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 36
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...
6.1.17 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.

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.
Page 43
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.
Camera features The camera features of the HR series are defined by the combination of its elec- tronics and firmware features. Firmware features can be upgraded with new firmware releases. 6 Feature description...
6.2.1 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 46
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). Exposure time of the next image can overlap with the frame readout of the cur- rent image (trigger pulse occurs when FVAL is high).
Page 47
When the rising edge of trigger signal occurs after frame readout has ended (FVAL is low), the start of exposure time is not synchronized to LVAL and expos- ure time starts after a short and persistent delay. Exposure time can be changed during operation. No frame is distorted during switching time.
Fig.: 6-23: Mode 1: External trigger with pulse width exposure control (overlap) Fig.: 6-24: Mode 1: External trigger with programmable exposure time (non-overlap) Fig.: 6-25: Mode 1: External trigger with programmable exposure time (overlap) 6.2.2 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.
INFO Use multiples of 15 ns to write durations into camera memory. 6.2.3 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).

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.: 6-29: Several gamma curves comparable to a LUT...
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.: 6-30: 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 54
White balance gets much more difficult. Con- trast 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 stand- ard filter.
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).

Fig.: 6-34: PWM intensity Examples of PWMs The integrals over both periods are equal. An equal amount of Photons will be emitted. The intensity of light is the same. The periods are equal in length. 6 Feature description...
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.

If your camera trigger is in the ms range or slower, we recommend to use the optical input. An optical input needs some current for operation. The SVS-Vistek optical input is specified to 5-24 V, 8 mA.
