Inch CS-Mount Cameras accept both types of lenses. C-Mount lenses require a 5mm adapter ring to be fitted. (Also available at SVS-VISTEK) C-Mount Cameras only accept C mount lenses as the flange to sensor distance does not allow a CS mount lens close enough to the Sensor to achieve a focused image.
Charge is an integration of time and light intensity on the element. Like this the image gets brighter the longer the CCD cell is exposed to light. The sensor converts light into charge and transports it to an amplifier and subsequently to the analog to digital converter (ADC). SVS-VISTEK–Feature-Set Basic Understanding...
SVS-VISTEK 7.1.2 Interline Transfer Interline Transfer is only used in CCD sensors. With a single pixel clock the charge from each pixel is transferred to the vertical shift register. At this time, the light sensitive elements are again collecting light. The charge in the vertical registers is transferred line by line into the horizontal shift register.
SVS-VISTEK 7.1.3 Global Shutter / Progressive Scan Unlike rolling shutter or interlaced scan modes all pixels are exposed at the same time. Fast moving objects will be captured without showing movement distortion. Figure 10: motion blur Figure 11 rolling shutter with...

SVS-VISTEK 7.1.6 Exposure See various exposure and timing modes in chapter: Basic capture modes. Combine various exposure timings with PWM LED illumination, refer to sequencer. Setting Exposure time Exposure time can be set by width of the external or internal triggers or programmed by a given value.
SVS-VISTEK 7.1.8 Bit-Depth Values of brighness are internally represented by numbers. Numbers are represented by bytes, consisting out of single bits. The number of bits for brightness representation is limiting the number of brightness values or colour values that can be represented. Bit depth defines how many unique colors or grey levels are available in an image after digitization.

SVS-VISTEK 7.1.9 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 monochrome, but considered as “raw”-format. The camera sensor has a color mosaic filter called “Bayer” filter pattern named after the person who invented it.
SVS-VISTEK 7.1.10 Resolution – active & effective As mentions in the specifications, there is a difference between the active and the effective resolution of almost every sensor. Some pixels towards the borders of the sensor will be used only to calibrate the sensor values.
SVS-VISTEK 7.1.11 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 randomly appearing electrons that will be detected as a signal.
SVS-VISTEK 7.1.12 Gain Setting gain above 0 dB (default) is another 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.
SVS-VISTEK 7.1.13 Image Flip 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 Figure 25: Figure of original image Figure 26: Figure of image horizontally flipped...
SVS-VISTEK 7.1.14 Binning Binning provides a way to enhance dynamic range, but at the cost of lower resolution. Instead of reading out each individual pixel, binning combines charge 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.
SVS-VISTEK When DVAL signal is enabled only every third pixel in horizontal direction is grabbed. Figure 30: Illustration of 2x2 binning 7.1.15 Decimation For reducing width or height of an image, decimation can be used. Columns or rows can be ignored.

(as soon as there is enough time later on to deliver the images) (not applicable to USB cameras) Please note, as soon as the internal memory buffer is filled up, frames will be dropped. Due to this reason, SVS-Vistek camers provide up to 512MB image buffer memory. Feature-Set...
SVS-VISTEK 7.2 Camera Features 7.2.1 Standard Tap Geometries Similar to other sensor readout technologies Camera Link is sending many pixel values in parallel at the same time. The image can be split in “taps” or “channels” which can be sent in parallel. The tap geometry is describing how many taps are read and how they are transmitted through the Camera Link interface.
SVS-VISTEK In a single-tap CCD sensor the readout of pixel charge is done sequentially. Pixel by pixel, line by line. The maximum frame rate is determined by the pixel clock frequency and the total number of pixels to be read out.
Page 43
SVS-VISTEK coming from the CCD. The fact that the separate analog output channels not being perfectly linear and the separate output amplifiers having physically different slopes leads to the necessity to sometimes manually or automatically adjust the gain levels of each channel independently to obtain a homogenous image.
SVS-VISTEK 7.2.4 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 multiples of 15 ns.
SVS-VISTEK 7.2.6 Basic Capture Modes Free Running Free running (fixed frequency) with programmable exposure time. Frames are readout continously and valid data is indicated by LVAL for each line and FVAL for the entire frame. There is no need to trigger the camera in order to get data. Exposure time is programmable via serial interface and calculated by the internal logic of the camera.
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 60 Sec (camera type dependent).

SVS-VISTEK Software Trigger Trigger can also be initiated by software (serial interface). NOTICE Software trigger can be influenced by jitter. Avoid Software trigger at time sensitive applications Feature-Set...
SVS-VISTEK 7.2.7 LookUp Table The LookUp 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.
Page 49
SVS-VISTEK Gamma Correction Using the LookUp Table makes is also possible to implement a logarithmic correction. 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.
SVS-VISTEK 7.2.8 In Partial Scan or Area-Of-Interest or Region-Of-Interest (ROI) -mode only a certain region will be read. Figure 43: Illustration of AOI limitation on a CCD sensor Selecting an AOI will reduce the number of horizontal lines being read.

SVS-VISTEK 7.3.3 Sequencer The sequencer is used when different exposure settings and illuminations are needed in a row. E.g. the scenario to be captured may occur in three different versions and should therefore be recorded with three different light source settings.
SVS-VISTEK 7.3.4 PWM Pulse width modulation Description of the function used within the sequencer or implemented by the pulseloop module During Pulse Width Modulation, a duty cycle is modulated by a fixed frequency square wave. This describes the ratio of ON to OFF as duty factor or duty ratio.
SVS-VISTEK P W M : H E I N T E N S I T Y O F A That duty ratio is calculated as: Δ% = t / T. It is written about the value of "t" as PWMChange0-3[SeqSelector] per sequence into the Registry.

SVS-VISTEK these kinds of interaction from power sources or switches. The disadvantage of an optical input is that it is slower in terms of signal transmission than a direct electrical connection. An optical input needs some current for operation. The SVS- Vistek optical input is specified to 5-24V, 8mA.
SVS-VISTEK 7.3.6 PLC/Logical Operation on Inputs The logic input combines trigger signals with Boolean algorithms. The camera provides AND, NAND, OR, NOR as below. You might connect 2 signals on the logic input. The result can be connected to a camera trigger signal or it may be source for the next logical operation with another input.
SVS-VISTEK If neither input is high, a low pulse_out (0) results. Combine trigger input one and two. Y = A v B No trigger input – one nor two – results in a high or a low level pulse_out. Invert both trigger inputs. By inverting the resulting pulse_out you will get the NOR I pulse Y = A ⊽...
