Page 29: Single Frame Mode
7.3.4 Acquisition Frame Rate (except cameras with Rolling Shutter sen- sors) With this feature Baumer introduces a clever technique to the VEX camera series, that enables the user to predefine a desired frame rate in continuous mode. For the employment of this mode the cameras are equipped with an internal clock genera- tor that creates trigger pulses. -

Page 36: Camera Functionalities
8.1.1 Image Format A digital camera usually delivers image data in at least one format - the native resolution of the sensor. Baumer cameras are able to provide several image formats (depending on the type of camera). Compared with standard cameras, the image format on Baumer cameras not only in- cludes resolution, but a set of predefined parameter. -
Page 37: Pixel Format
8.1.2 Pixel Format On Baumer digital cameras the pixel format depends on the selected image format. 8.1.2.1 General Definitions RAW: Raw data format. Here the data are stored without processing. Bayer: Raw data format of color sensors. Color filters are placed on these sensors in a checkerboard pattern, generally in a 50% green, 25% red and 25% blue array. - Page 38 For RGB or BGR these 8 bits per channel equal 24 bits overall. Two bytes are needed for transmitting more than 8 bits per pixel - even if the second byte is not completely filled with data. In order to save bandwidth, the packed formats were introduced to Baumer VEX cameras. In this formats, the unused bits of one pixel are filled with data from the next pixel. 8 bit: Figure 13 ►...

Page 40: Exposure Time
Notice Due to the sensor, fixed pattern noise effects can occur at high exposure times. You can counteract this by setting the gain to a value of approximately 1.5 and reducing the exposure time accordingly. On Baumer VEX cameras, the exposure time can be set within the following ranges (step size 1μsec): 8.1.3.1 VEXG Notice... -

Page 42: Region Of Interest
8.1.5 Region of Interest With the "Region of Interest" (ROI) function it is possible to predefine a so-called Region of Interest (ROI) or Partial Scan. This ROI is an area of pixels of the sensor. On image acquisition, only the information of these pixels is sent to the PC. This function is employed, when only a region of the field of view is of interest. It is coupled to a reduction in resolution. The ROI is specified by four values: ▪... -
Page 43: Binning
Higher sensitivity enables shorter exposure times. Baumer cameras support three types of Binning - vertical, horizontal and bidirectional. In unidirectional binning, vertically or horizontally neighboring pixels are aggregated and reported to the software as one single "superpixel". - Page 44 8.1.6.2 Color Binning Color binning is calculating on the camera (no higher frame rates) – The sensor does not support this binning operation. At color binning the color values of neighboring pixels with the same color are combined. Binning Illustration without Figure 23 ►...

Page 45: Brightness Correction
8.1.7 Brightness Correction The aggregation of charge carriers may cause an overload. To prevent this, brightness correction was introduced. Brightness correction can be swiched on or off. Here, three binning modes need to be considered separately: Binninig Realization 1x2 binning is performed within the sensor, binning correction also takes place here. -

However, this causes low output signals from the camera and results in dark images. To solve this issue, the signals can be amplified by a user-defined gain factor within the camera.

8.3 Pixel Correction 8.3.1 General information A certain probability for abnormal pixels - the so-called defect pixels - applies to the sen- sors of all manufacturers. The charge quantity on these pixels is not linear-dependent on the exposure time. The occurrence of these defect pixels is unavoidable and intrinsic to the manufacturing and aging process of the sensors. -
Page 49: Correction Algorithm
Corrected Pixels 8.3.3 Add Defect Pixel to Defect pixel list As stated previously, this list is determined within the production process of Baumer cam- eras and stored in the factory settings. Additional hot or cold pixels can develop during the lifecycle of a camera. In this case Baumer offers the possibility of adding their coordinates to the defect pixel list. - Page 50 Procedure (add Defect Pixel to defect pixel list) Start the Camera Explorer. Connect to the camera. Select the profile GenICam Expert. Open the category LUT Control. Locate an empty Defect Pixel List Index (Defect Pixel List Entry PosX = 0 / De- fect Pixel List Entry PosY = 0). Avoid using existing coordinates! Determine the coordinates of the defect pixel.

8.4.6 Debouncer The basic idea behind this feature was to seperate interfering signals (short peaks) from valid square wave signals, which can be important in industrial environments. Debouncing means that invalid signals are filtered out, and signals lasting longer than a user-defined testing time t will be recognized, and routed to the camera to induce a trigger. DebounceHigh In order to detect the end of a valid signal and filter out possible jitters within the signal, a ... -
Page 55: Exposureactive (Flash Signal)
8.4.7 ExposureActive (Flash Signal) This signal is managed by exposure of the sensor. Furthermore, the falling edge of the ExposureActive output signal can be used to trigger a movement of the inspected objects. Due to this fact, the span time used for the sensor readout t can be used optimally in industrial environments. -

Page 60: Example 1: Multi Camera Operation - Minimal Ipg
9.3.1 Example 1: Multi Camera Operation – Minimal IPG Setting the IPG to minimum means every image is transfered at maximum speed. Even by using a frame rate of 1 fps this results in full load on the network. Such "bursts" can lead to an overload of several network components and a loss of packets. -

9.4 Multicast Multicasting offers the possibility to send data packets to more than one destination ad- dress – without multiplying bandwidth between camera and Multicast device (e.g. Router or Switch).

▪ DHCP Request Once the client has received this DHCPOFFER, the transaction needs to be con- firmed. For this purpose the client sends a so called DHCPREQUEST broadcast to the network. This message contains the IP address of the offering DHCP server and informs all other possible DHCPservers that the client has obtained all the necessary information, and there is therefore no need to issue IP information to the client. -
Page 64: Packet Resend
9.6 Packet Resend Due to the fact, that the GigE Vision standard stipulates using a UDP - a stateless user ® datagram protocol - for data transfer, a mechanism for saving the "lost" data needs to be employed. Here, a resend request is initiated if one or more packets are damaged during transfer and - due to an incorrect checksum - rejected afterwards. -

9.6.3 Fault 2: Lost Packet at the End of the Data Stream In case of a fault at the end of the data stream, the application will wait for incoming packets for a predefined time. When this time has elapsed, the resend request is triggered and the "lost" packets will be resent. ◄ Figure 46 Resending of lost pack- ets at the end of the data stream. -
