Auto gain For automatic adjustment of gain refer to auto exposure (see "Auto exposure" on page 40). When using auto-gain with steps of gain the noncontinuous 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 25: Color
6.1.4 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.: 6-3: Sensor with Bayer pattern The camera sensor has a color mosaic filter called “Bayer” filter pattern named after the person who invented it.
Page 26: Flip Image
6.1.5 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.: 6-4: Original image Fig.: 6-5: Horizontal flip 6 Feature description...
Page 27: Binning
Fig.: 6-6: Vertical flip 6.1.6 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. Binning is only used with monochrome CCD Sensors. For reducing resolution on color sensors refer to "Decimation"...
Page 28: Decimation
Horizontal binning Accumulates horizontal pixels. Fig.: 6-8: 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.: 6-9: 2x2 binning 6.1.7 Decimation For reducing width or height of an image, decimation can be used. Columns or rows can be ignored.
Page 29 Fig.: 6-10: Horizontal decimation Fig.: 6-11: 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.: 6-12: Decimation on color sensors 6 Feature description...
Page 30: Genicam
6.1.8 GenICam provides a generic programming interface to control all kinds of cameras and devices. Regardless of the interface technology (GigE Vision, USB3 Vision, CoaXPress, Camera Link, etc.) or implemented feature, the application programming interface (API) will always be the same. The SNFC makes sure the feature names are similar throughout the manufacturers, mak- ing it more easy to switch camera models.
Page 31: Trigger Modes
6.1.9 Trigger modes To start capturing images, the camera has to receive a trigger signal. This trig- ger signal can be a software trigger, it might be an electric signal on the hard- ware I/O or it can be a timed trigger (sequence of images or "Precision Time Protocol").
Page 32 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...
Page 33 6 Feature description...
Page 34: Shutter Modes
6.1.10 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.
Page 35 interface). Nonetheless, the maximum achievable frame rate with applied ROI will be the maximum frame rate of the sensor reading the full sensor area (internal full sensor speed), please refer to relating sensor specs. Artifacts All pixel show same artifacts Deformed image of moving objects Exposure with flash Fig.: 6-13: flash control with rolling shutter...
Page 36 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.
Page 37 As shown here, after triggering only part of the sensor is sensitive to light (scan- ning time). As soon as scanning time has finished, all pixels are sensitive to light, the sensor is fully open. While being fully open this is the time where flash- ing should happen.
Page 38 Global Reset Release Mode INFO Global reset release is a image sensor feature. The sensor being used in the hr120 cameras does not provide global reset release. 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.
Page 39: Exposure
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.
Page 40: Exposure Speed
6.1.12 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 predictable maximum frame rates with heavy interface bus load. Maximum frame rate might depend on: Pixel clock Image size Tap structure...
Page 41 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 Feature description...
Page 42: Acquisition And Processing Time
6.1.14 Acquisition and processing time The camera has to read the sensor, process the data to a valid image and trans- fer 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 43: Bit Depth
6.1.15 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. Bit depth defines the max- imum unique colors or gray levels in an image. bit depth No of gray values = 2 All SVCam models support 8-bit format.
Page 44 NOTICE Unpacking has to be done manually, this is not a GenTL function. Thus, image acquisition in packed formats won’t be supported by most 3 party software products. 6 Feature description...
Page 45: Roi / Aoi
6.1.16 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.: 6-18: 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.

Prominent examples include the analysis of the orientation of carbon fibers, the visualization of tensions in glass caused by stress induced birefringence, the reduction of reflections and glare or simply the enhancement of contrast between materials that are difficult to tell apart with conventional imaging modalities.

Page 50: Camera Features
Camera features The camera features of the EXO series USB3 are defined by the combination of its electronics and firmware features. Firmware features can be upgraded with new firmware releases. 6.2.1 IR / glass filter To avoid influences of infrared light to your image, cameras are equipped with an IR (Infrared) cut filter or an anti-refection coated glass (AR filter).
Page 51: Shading Correction
Fig.: 6-22: 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 short- ening this distance.
Page 52 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 flatfield image out of a non-uni- form image regardless of the reasons of the non-uniformity. Before doing shad- ing correction, make sure your lens is clean and in perfect condition.
Page 53 First, shading reference images have to be taken with shading correction dis- abled (use 16 images minimum). Save it on disk. Use std .bmp files here, if pos- sible with more than 8 bit. 1. Run shading assistant->Generate Map Fig.: 6-23: Shading control disabled 2.
Page 54: Defect Pixel Correction
5. Save map to disk. This file can be used in programmed environments via SDK as well. 6. Upload it to the camera and see the result. If lighting did not change from start of procedure, you should see a uniform image with enabled shading control.
Page 55 Defect Pixels either be dark pixels, i.e. that don’t collect any light, or bright pixels (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.
Page 56 Defect pixel correction is possible with certain models only. See camera specs whether your model does support this. In case your camera is not supporting, the assistant will not be selectable. For easy image processing, it is recommended to have pixel correction activated Pixel correction maps can be saved and loaded The std factory map can be selected any time...

Page 58: Look-Up Table
6.2.4 Look-up table The look-up 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 59 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.: 6-26: Several gamma curves comparable to a LUT...
Page 60: Roi / Aoi
6.2.5 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.: 6-27: 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 61: Basic Capture Modes
6.2.6 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 62: Micro Four Thirds Lenses
Fig.: 6-29: Basic capture modes - triggered mode (pulse width with 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 63: Read-Out Control
Fig.: 6-31: Micro Four Thirds in close view Mounting lenses INFO There is a difference in the back focus distance between „Four Thirds“-lenses and „Micro Four Thirds“ lenses. Your camera is equipped with a “Micro Four Thirds” connector. 1. Mount a Micro Four Thirds lens on the camera before powering up the camera.
Page 64: Temperature Sensor
Fig.: 6-32: Illustration of physical data stream in time 6.2.9 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).

Page 66: Shading Correction
6.2.13 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). 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).
Page 67 creation process takes any image with any (!) illumination and creates a shad- ing map out of it. This shading map afterwards will be uploaded into the camera. NOTICE Shading correction is possible with certain models only. See camera specs whether your model does support this.
Page 68 2. With SVCapture load these reference images. 3. See shading in the preview 4. Generate the shading map 5. Save map to disk. This file can be used in programmed environments via SDK as well. 6. Upload it to the camera and see the result. If lighting did not change from start of procedure, you should see a uniform image with enabled shading control.
Page 69: Defect Pixel Correction
7. Run camera with same lighting to see corrected image. How it works The tool will divide the image into squares of 16x16 pixel. Out of every 16x16 pixel cluster a set of shading values consisting of specific gain and offset per cluster is calculated.
Page 70 A factory created defect map (SVS map), defying known defects, is stored in the camera. A custom defect map can be created by the user. A simple *.txt file with coordinates must be created. The user must locate the pixel defects manu- ally.

Page 74: I/O Features
I/O Features The SVCam cameras are equipped with several inputs and outputs, providing state-of-the-art control regarding input and output channels. All I/O functions are realized as modules. These functions can be connected in the GenICam tree. 6.3.1 GenICam provides a generic programming interface to control all kinds of cameras and devices.
Page 75: Assigning I/O Lines - Iomux
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.
Page 76 LineSelector Translation Line18 Pulse0 Line19 Pulse1 Line20 Pulse2 Line21 Pulse3 Line22 Uart2 In The input and output lines for Strobe and Trigger impulses can be arbitrarily assigned to actual data lines. Individual assignments can be stored persistently to the EPROM. Default setting can be restored from within the Camera. INFO Refer to pin-out in input / output connectors when physically wiring.

Page 81 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).

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.

Page 92: Optical Input
6.3.6 Optical input In many trigger signals you find noise, transients and voltage spikes. These are able to damage components in the camera and trigger signal interpretation might be difficult. An optical input separates the electrical trigger and camera circuits. The benefit of such an optical input is to avoid all these kinds of interaction from power sources or switches.
