Page 49: Acquisition Modes And Timings
(t ) is given by the particular sensor and image format. readout Baumer cameras can be operated with differtent acquisition modes, the Continuous Mode (Free Running Mode), the Acquisition Frame Rate Mode, the Single Frame Mode, the Multi Frame Mode and the Trigger Mode. The cameras can be operated non-overlapped or overlapped. -
Page 50: Single Frame Mode
AcquisitionFrameCount controls the number of captured frames. Then the acquisition is automatically stopped. 6.3.4 Acquisition Frame Rate Mode With this feature Baumer introduces a clever technique to the CX camera series, that enables the user to predefine a desired frame rate in continuous mode. For the employment of this mode the cameras uses an internal clock generator that cre- ates trigger pulses. -
Page 51: Trigger Mode
6.3.5 Trigger Mode After a specified external event (trigger) has occurred, image acquisition is started. De- pending on the interval of triggers used, the camera operates non-overlapped or over- lapped in this mode. With regard to timings in the trigger mode, the following basic formulas need to be taken into consideration: Case Formula earliestpossibletrigger(n+1) readout(n) -
Page 52: Overlapped Operation: T
6.3.5.1 Overlapped Operation: t exposure(n+2) exposure(n+1) In overlapped operation attention should be paid to the time interval where the camera is unable to process occuring trigger signals (t ). This interval is situated between two notready exposures. When this process time t has elapsed, the camera is able to react to notready external events again. -
Page 53: Exposure(N+1)
6.3.5.2 Overlapped Operation: t > t exposure(n+2) exposure(n+1) If the exposure time (t ) is increased from the current acquisition to the next acquisi- exposure tion, the time the camera is unable to process occurring trigger signals (t ) is scaled notready down. This can be simulated with the formulas mentioned above (no. 2 or 4, as is the case).

Page 56: Timings Of The Image Transmission
6.3.6 Timings of the image transmission 6.3.6.1 VCXG Trigger Mode The transfer of the first image starts after data for a complete packet size is stored in camera's TX memory. All further images start the transfer immediately after the first one is completed, if the camera works in burst mode with a high frame rate and the sensor acquires images faster than the interface can transfer. -
Page 57: Advanced Timings For Gige Vision ® /Usb3 Vision Tm Message Channel
If the camera is unable to process incoming trigger signals, which means the camera should be triggered within the interval t , these triggers are skipped. On Baumer CX notready cameras the user will be informed about this fact by means of the event "TriggerSkipped". -
Page 58: Triggeroverlapped

Page 61: Camera Functionalities
7.1.1 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. -

7.1.4 Fixed Pattern Noise Correction (FPNC) CMOS sensors exhibit nonuniformities that are called Fixed Pattern Noise (FPN). How- ever it is no noise but a fixed variation from pixel to pixel that can be corrected. The advan- tage of using this correction is a more homogeneous picture which may simplify the image analysis. Variations from pixel to pixel of the dark signal are called dark signal nonunifor- mity (DSNU) whereas photo response nonuniformity (PRNU) describes variations of the ... -

Page 73: Region Of Interest
7.1.7 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: ▪... -

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 82: Gain
7.4.2 Gain In industrial environments motion blur is unacceptable. Due to this fact exposure times are limited. 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. This gain factor is adjustable. Notice Increasing the gain factor causes an increase of image noise. -

Page 84: Pixel Correction
7.5 Pixel Correction 7.5.1 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 85: Correction Algorithm
7.5.2 Correction Algorithm On Baumer cameras the problem of defect pixels is solved as follows: ▪ Possible defect pixels are identified during the production process of the camera. ▪ The coordinates of these pixels are stored in the factory settings of the camera. ▪ Once the sensor readout is completed, correction takes place: ▪... -
Page 86: Add Defect Pixel To Defectpixellist
7.5.3 Add Defect Pixel to Defectpixellist 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 defectpixellist. -

7.6.4 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 second testing time t was introduced. This timing is also adjustable by the user. DebounceLow If the signal value falls to state low and does not rise within t , this is recognized... -
Page 95: Exposureactive (Flash Signal)
7.6.5 ExposureActive (Flash Signal) This signal is managed by exposure of the sensor. Furthermore, the falling edge of the ExposureActive signal can be used to trigger a move- ment of the inspected objects. Due to this fact, the span time used for the sensor readout can be used optimally in industrial environments. -
Page 96: Exposureactivedelay
7.6.5.1 ExposureActiveDelay As previously stated, the Timer feature can be used to start the connected illumination earlier than the sensor exposure. This implies a timer configuration as follows: ▪ The flash output needs to be wired to the selected internal Timer signal. ▪ Trigger source and trigger activation for the Timer need to be the same as for the sensor exposure. -

≥ 7.6.7 Counter ( Rel. 2 only) You can choose between two counters (Counter Selector). With each of this counters you can count the events in the table below. The count values of the events are readable and writable. With the feature Counter Trigger Source you can specify which event should be counted. These events can also be used as a counter reset source. -
Page 98: Sequencer (≥ Rel. 2 Only)
7.7 Sequencer (≥ Rel. 2 only) The Sequencer enables the possibility of image series recording including automated re-parameterization of the camera based on different events and signals. Therefore the desired camera settings for each step are stored in so called sequencer sets. Stringing together a number of these sequencer sets results in a sequence. The connec- tion of sequences is done by using different paths. -
Page 99: Sequencer Configuration
7.7.2 Sequencer configuration In order to avoid overwriting current camera settings while configuring a sequencer, the camera needs to be set to the sequencer configuration mode. Once the camera is set to the sequencer configuration mode, the individual sequencer sets can be selected via the SequencerSetSelector, configured and saved by executing SequencerSetSave. Starting the configured sequence requires to switch the sequencer configuration mode off and to enable the sequencer mode. 7.7.3 Sequencer command overview Feature Values Description SequencerMode Enables / disables the se- quencer mechanism On/Off To use this feature, the Se- quencerConfigurationMode must be off.

Page 101: Device Reset
The feature Device Reset corresponds to the turn off and turn on of the camera. This is necessary after a parameterization (e.g. the network data) of the camera. The interrupt of the power supply ist therefore no longer necessary. 7.9 User Sets Four user sets (0-3) are available for the Baumer cameras of the VCX series. User set 0 is the default set and contains the factory settings. User sets 1 to 3 are user-specific and can contain any user definable parameters. These user sets are stored within the camera and can be loaded, saved and transferred to other cameras of the VCX series. -

8.3.1 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. -

▪ 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 115: Packet Resend
8.7 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. -
