Page 19: Resolution
Fig. 5-1: Noise caused by too much gain Auto gain INFO For automatic adjustment of gain refer to auto exposure (see "Auto exposure" on page 34). When using auto-gain with steps of gain, the non-continuous gain adjustment might be visible in final image. Depending on your application it might be prefer- able to use fixed gain values instead and modify exposure with exposure time. -
Page 20: Color
Signal Offset Dark noise Pixel Fig. 5-2: Dark noise cut off by the offset Most noise is proportional to temperature. The offset is automatically regulated by the camera sensor to compensate for the surrounding temperature changes by referencing specific pixels as „black“, i.e. never exposed to light. So the offset will be set dynamically and conditioned to external influences. - Page 21 Camera Link frame grabbers need information of the sequence order of the col- ors. The order depends on sensor type. USB3 and GigE cameras provide this in their XML file. INFO It is recommended to use an IR cut filter for color applications INFO Industrial vision cameras are not intended to display colors according to human perception.

Page 24: Binning
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. -

Page 26: Decimation
Fig. 5-9: 2x2 binning 5.1.7 Decimation For reducing width or height of an image, decimation can be used. Columns or rows can be ignored. INFO Refer to "ROI / AOI" on page 46 for reducing data rate by reducing the region you are interested in. -
Page 27: Genicam
Fig. 5-11: Vertical decimation 5.1.8 GenICam The GenICam standard provides a generic programming interface to control all kinds of cameras and devices. Regardless of the interface technology (GigE Vision, USB 3 Vision, CoaXPress, Camera Link, etc.) or implemented feature, the application programming interface (API) will always be the same. -
Page 28: Trigger Modes
5.1.9 Trigger modes To start capturing images, the camera has to receive a trigger signal. This trigger signal can be a software trigger, it might be an electric signal on the hardware I/O or it can be a timed trigger (sequence of images or "Precision Time Protocol"). -
Page 29: Fig. 5-13: Mode 2: External Trigger With Programmable Exposure Time (Non Overlap)
Fig. 5-13: Mode 2: External trigger with programmable exposure time (non overlap) 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 INFO The diagrams below are identical for CCD and CMOS technique. -

Page 31: Fig. 5-18: Flash Control With Rolling Shutter
Next integration has to wait for finished readout (per line) No external exposure control (expose while trigger signal active) Limitations Use short exposure times for preventing blur / deforming artifacts. Image of mov- ing object on sensor must not move more than half pixel width. In case of moving objects, exposure movement on sensor has to be shorter than half a pixel for whole image. -
Page 32: Fig. 5-19: Rolling Shutter Lines Light Sensitivity Versus Time
Make sure to protect from changing environment light (recommendation: flash strobe in darkness). Short Flash strobe times with moving objects. Light control with rolling shutter 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. -
Page 33: Exposure
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 must always be read out. -
Page 34: Exposure Speed
Setting exposure time Exposure time can be set by width of the external or internal triggers or pro- grammed by a given value. 5.1.12 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 pre- dictable maximum frame rates with heavy interface bus load. -
Page 35: Bit Depth
Fig. 5-20: Acquisition and processing time On the other hand, while processing and transferring the image the sensor might capture already the next frame. 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 represented. -
Page 36: Fig. 5-21: Original And Shading Corrected Image
Fig. 5-21: Original and shading corrected image This shading can be caused by non-uniform illumination, non-uniform camera sensitivity, vignetting of the lens, or even dirt and dust on glass surfaces (lens). Shading correction is a procedure to create a flat-field image out of a non-uni- form image regardless of the reasons of the non-uniformity. - Page 37 Creating a shading map Shading maps are test files containing a description for the camera how to bal- ance shading control. Shading maps can be created and uploaded to the cam- era with SVCapture. The shading map creation process takes any image with any illumination and creates a shading map out of it.

enabled shading control. Run the camera with same lighting to see corrected image. 5.2.3 Defect pixel correction All image sensor have defect pixels in a lesser or greater extent. Type and num- ber of defects determine the quality grade (quality classification) of the sensor. Defect Pixel Correction is using information from neighboring pixels to com- pensate for defect pixels or defect pixel clusters (cluster may have up to five defect pixels). -
Page 40: Fig. 5-23: Illustration Of A Defect Pixel
The *.txt file can be uploaded into the camera. Beware of possible Offset! Defect maps can be switched off to show all default defects, and switched back on to improve image quality. Unlike shading correction, defect pixel correction suppresses single pixels or clusters and reconstructs the expected value by interpolating neighboring pixel values. - Page 41 For easy image processing, it is recommended to have pixel correction activ- ated 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.

Page 44: Fig. 5-24: Custom Lut Adding Contrast To The Mid-Tones
Fig. 5-24: 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 cor- rection. 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: Basic Capture Modes
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. With CMOS Sensors, AOI is sensor dependent. Some CMOS sensors require the camera to read full horizontal sensor lines internally. Reducing horizontal size with AOI might result in limited frame rate gain. -
Page 48: Read-Out Control
Fig. 5-29: Mode 1: External Trigger with Pulse Width Exposure Control (overlap) Exposure time of the next image can overlap with the frame readout of the cur- rent image (rising edge of trigger pulse occurs when FVAL is high). When this happens: the start of exposure time is synchronized to the falling edge of the LVAL signal. -
Page 49: Temperature Sensor
Fig. 5-31: Illustration of physical data stream in time 5.2.8 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 software monitoring, the camera indicates high temperature by a red flashing LED (see flashing LED codes). - Page 50 Save user sets Select the user set to be saved in the UserSetSelector and save it with the User- SetSave command.
