  • Page 17: Feature Description

    SVS-VISTEK 5 Feature description 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 with your exact model.

  • Page 18: Acquisition And Processing Time

    SVS-VISTEK 5.1.4 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 19: Color

    SVS-VISTEK 5.1.7 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. CCD with Bayer Pattern The camera sensor has a color mosaic filter called “Bayer” filter pattern named after the person who invented it.

  • Page 20: Resolution

    SVS-VISTEK 5.1.8 Resolution As mentioned in the specifications, there is a difference between the numerical sensor resolution and the camera resolution. Some pixels towards the borders 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.

  • Page 21: Gain

    SVS-VISTEK 5.1.10 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 22: Flip Image

    SVS-VISTEK 5.1.11 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. original image horizontal flip vertical flip Feature description...

  • Page 23: Binning

    SVS-VISTEK 5.1.12 Binning Binning provides a way to enhance dynamic range, but at the cost of lower resolution. 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 26: Camera Features

    SVS-VISTEK 5.2 Camera Features 5.2.1 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 27 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).
  • Page 28 SVS-VISTEK 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. Detailed Info of External Trigger Mode Dagrams below are aquivalent for CCD and CMOS technique.

  • Page 29: System Clock Frequency

    SVS-VISTEK 5.2.2 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. Using the system clock as reference of time, time settings can only be made in steps. In this example, the transfer rate is 66.7 MHz, thus resulting in steps of 15 ns.

  • Page 32: Read-Out-Control

    SVS-VISTEK 5.2.5 Read-Out-Control Read-Out-Control defines a delay between exposure and data transfer. Read-Out-Control 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.

  • Page 33: Lookup Table

    SVS-VISTEK 5.2.6 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 34: Roi / Aoi

    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.
  • Page 35 SVS-VISTEK AOI on a CCD 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 term of frames per second. With CCD sensors, setting an AOI on the left or right side does not affect the frame rate, as lines must be read out completely.

    Color sensor images are affected, especially red will be higher in intensity than visible with bare eyes. White balance gets much more difficult. Contrast is lower. 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.
  • Page 38 SVS-VISTEK Figure 4: IR cut filter light transmission Focal impact of filters As an IR cut filter mainly consist of a small layer of glass (1 mm thick) there is an impact on the flange focal distance. Refraction within the layer cause shortening this distance.

    (hot pixel) that always are outputting a bright signal. 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.

    SVS-VISTEK 5.3.2 PWM During Pulse Width Modulation (PWM), 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. Why PWM? Many electrical components must be provided with a defined voltage.

  • Page 48: Led Strobe Control

    SVS-VISTEK 5.3.5 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 controlled via GenICam, any GenICam-compliant 3 party software is able to control the light as well.
  • Page 49 SVS-VISTEK LEDs in Flash Mode Most LED lights can cope with currents higher than specs. This gives you higher light output when light is ON. Please refer to your LED specs if LED overdrive is permitted. By controlling the duty cycle the intensity of light and current can be controlled.

  • Page 55: Optical Input

    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 5-24V, 8mA. The opto coupler galvanically separates electrical circuits by emitting light on one side and interpreting light in the other.

  • Page 56: Plc/Logical Operation On Inputs

    SVS-VISTEK 5.3.8 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 combine combine true/false states of the inputs to determine camera actions. The result can be connected to a camera trigger signal or it may be source for the next logical operation with another input.

  • Page 57: Serial Data Interfaces

    SVS-VISTEK 5.3.9 Serial data interfaces (ANSI EIA/) TIA-232-F RS-232 and RS-422 (from EIA, read as Radio Sector or commonly as Recommended Standard) are technical standards to specify electrical characteristics of digital signalling circuits. Serial connection might be used to control SVCams. These signals are used to send low-power data signals to control exposure, light or lenses (MFT).
