  • Page 18: Exposure Speed

    SVS-VISTEK Figure 5: moving object, interlaced camera Using flash with global shutter is straight forward: just make sure your flash is on while shutter is open, thus all pixels are exposed to light the same time. You might flash at any time within exposure time.

  • Page 19: Exposure

    SVS-VISTEK 6.1.4 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.

  • Page 25: Camera Features

    SVS-VISTEK 6.2 Camera Features 6.2.1 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 26 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 27 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 28: System Clock Frequency

    SVS-VISTEK 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. 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.

    (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.

  • Page 33: Shading Correction

    SVS-VISTEK 6.2.7 Shading Correction The interactions between objects, illumination, and the camera lens might lead to a non-uniform flatfield in brightness. Shading describes the non- uniformity of brightness from one edge to the other or center towards edge(s). Figure 17: Original and shading corrected image...
  • Page 34 SVS-VISTEK In contrary to any shading correction being done after image recording, the method described here will hardly affect the dynamic range of the image. The task is done with shading maps. Being applied before final pixel quantization, a significant improvement in image quality is the result.

    SVS-VISTEK 6.3 I/O Features 6.3.1 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.

  • Page 41: Strobe Control

    SVS-VISTEK 6.3.3 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 42 SVS-VISTEK LED s i n Fl a s h M od e 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.

  • Page 47: Optical Input

    The disadvantage of an optical input is that it is slower in terms of signal transmission and slew rate than a direct electrical connection. An optical input needs some current for operation. The SVS-Vistek optical input is specified to 5-24V, 8mA.

  • Page 48: Plc/Logical Operation On Inputs

    SVS-VISTEK 6.3.6 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 6.3.7 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 signaling circuits. In the SVCam’s these signals are used to send low-power data signals to control light or lenses (MFT).
