Image Acquisition Control 6 Image Acquisition Control This section provides detailed information about controlling image acquisition. You will find details about setting the exposure time for each acquired image and about how the camera’s maximum allowed acquisition frame rate can vary depending on the current camera settings. 6.
Image Acquisition Control 6.1.2 Acquiring One Image at a Time In “single frame” operation, the camera acquires and transmits a single image. To select single frame operation, the camera’s Acquisition Mode parameter must be set to Single Frame. To begin image acquisition, execute an Acquisition Start command. Exposure time is determined by the value of the camera’s exposure time parameter.
Image Acquisition Control // set camera in continous mode Camera.AcquisitionMode.SetValue( AcquisitionMode_Continuous ); // set a frame rate and getting the resulting frame rate Camera.AcquisitionFrameRateEnable.SetValue( true ); Camera.AcquisitionFrameRateAbs.SetValue( 20.5 ); double resultingFrameRate = Camera.ResultingFrameRateAbs.GetValue(); You can also execute the Acquisition Start and Stop commands by using the API.
Image Acquisition Control 6.2 Controlling Image Acquisition with a Software Trigger You can configure the camera so that image acquisition will be controlled by issuing a software trigger. The software trigger is issued by executing a Trigger Software command. Image acquisition starts when the Trigger Software command is executed. The exposure time for each image is determined by the value of the camera’s exposure time parameter. Figure 15 illustrates image acquisition with a software trigger.
Image Acquisition Control You can also use the Basler pylon Viewer application to easily set the parameters. For more information about the pylon Viewer, see Section 3.1 on page 17. 6.2.2 Acquiring a Single Image by Applying One Software Trigger You can set the camera to react to a single software trigger and then issue a software trigger to begin image acquisition. To do so, follow this sequence: 1. Access the camera’s API and set the exposure time parameter for your desired exposure time. 2.
Image Acquisition Control 6.2.3 Acquiring Images by Applying a Series of Software Triggers You can set the camera to react to multiple applications of the software trigger and then apply a series of software triggers to acquire images. To do so, follow this sequence: 1. Access the camera’s API and set the exposure time parameter for your desired exposure time. 2. Set the value of the camera’s Acquisition Mode parameter to Continuous. 3. Execute an Acquisition Start command.
Image Acquisition Control Camera.AcquisitionFrameRateAbs.SetValue( 60.0 ); double resultingFrameRate = Camera.ResultingFrameRateAbs.GetValue( ); // how to disable the FrameRateAbs parameter Camera.AcquisitionFrameRateEnable.SetValue( false ); For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide and API Reference. You can also use the Basler pylon Viewer application to easily set the parameters. For more information about the pylon Viewer, see Section 3.
Image Acquisition Control 6.3 Controlling Image Acquisition with a Hardware Trigger You can configure the camera so that an external hardware trigger (ExTrig) signal applied to the camera’s input line will control image acquisition. A rising edge or a falling edge of the ExTrig signal can be used to trigger image acquisition. The ExTrig signal can be periodic or non-periodic.
Image Acquisition Control 6.3.1 Exposure Modes If you are triggering exposure start with an ExTrig signal, two exposure modes are available, "timed" and "trigger width." Timed Exposure Mode When timed mode is selected, the exposure time for each image is determined by the value of the camera’s exposure time parameter. If the camera is set for rising edge triggering, the exposure time starts when the ExTrig signal rises.
Image Acquisition Control Note The trigger width exposure mode is not available on slA750-60fm cameras. The trigger width exposure mode is available on all other camera models. When you operate the camera in trigger width exposure mode, you must use the camera’s exposure setting to set an exposure time. The exposure time setting will be used by the camera to operate the trigger ready signal. You should adjust the exposure setting to represent the shortest exposure time you intend to use.
Image Acquisition Control Camera.ExposureTimeAbs.SetValue( 3000 ); // set for the width exposure mode, set minimum exposure time to 3000 µs Camera.ExposureMode.SetValue( ExposureMode_TriggerWidth ); Camera.ExposureTimeAbs.SetValue( 3000 ); For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide and API Reference. You can also use the Basler pylon Viewer application to easily set the parameters. For more information about the pylon viewer, see Section 3.
Image Acquisition Control 6.3.3 Acquiring a Single Image by Applying One Hardware Trigger Transition You can set the camera to react to a single transition of an external hardware trigger (ExTrig) signal and then you can transition the ExTrig signal to begin image acquisition. When you are using an ExTrig signal to start image acquisition, you should monitor the camera’s trigger ready (TrigRdy) output signal and you should base the use of your ExTrig signal on the state of the trigger ready signal.
Image Acquisition Control For more information about the pylon Viewer, see Section 3.1 on page 17. For more information about the Trigger Ready signal, see Section 6.7 on page 57. For more information about the camera’s exposure time parameter, see Section 6.4 on page 51. 6.3.
Image Acquisition Control You can set the exposure time and the Acquisition Mode parameter values from within your application software by using the pylon API. You can also execute the Acquisition Start and Stop commands. The following code snippet illustrates using the API to set the parameter values and execute the commands: Camera.TriggerSelector.SetValue( TriggerSelector_AcquisitionStart ); Camera.ExposureMode.SetValue( ExposureMode_Timed ); Camera.ExposureTimeAbs.SetValue( 3000 ); Camera.
Image Acquisition Control 6.4 Exposure Time Parameters Many of the camera’s image acquisition modes require you to specify an exposure time. There are two ways to set exposure time: by setting "raw" values or by setting an "absolute value". The two methods are described below. You can use whichever method you prefer to set the exposure time. The exposure time must not be set below a minimum specified value. The minimum exposure time varies by camera model as shown in Table 9.
Image Acquisition Control Changing the Exposure Time Base Normally, the exposure time is adjusted by setting the value of the Exposure Time Raw parameter as explained above. However, if you require an exposure time that is longer than what you can achieve by changing the value of the Exposure Time Raw parameter alone, the Exposure Time Base Abs parameter can be used to change the exposure time base.
Image Acquisition Control 6.4.2 Setting the Exposure Time Using "Absolute" Settings You can also set the exposure time by using an "absolute" value. This is accomplished by setting the Exposure Time Abs parameter. The units for setting this parameter are µs and the value can be set in increments of 1 µs.
Image Acquisition Control 6.5 Overlapping Exposure and Sensor Readout (All Models Except slA750-60fm) Note The information in this section applies to all camera models except the slA750-60fm fm/fc. For information about slA750-60fm cameras, see Section 6.6 on page 56. The image acquisition process on the camera includes two distinct parts. The first part is the exposure of the pixels in the imaging sensor.
Image Acquisition Control Image Acquisition N Exposure Readout Image Acquisition N+1 Exposure Readout Image Acquisition N+2 Exposure Readout Image Acquisition N+3 Exposure Readout Time Fig. 20: Overlapped Exposure Determining whether your camera is operating with overlapped or non-overlapped exposures is not a matter of issuing a command or switching a setting on or off. Rather the way that you operate the camera will determine whether the exposures are overlapped or not overlapped.
Image Acquisition Control For more detailed guidelines about using an external trigger signal with the trigger width exposure mode and overlapped exposure, refer to the application notes called "Using a Specific External Trigger Signal with Overlapped Exposure" (AW000565xx000). The application notes are available in the downloads section of the Basler website: www.baslerweb.com/indizes/download_index_en_31412.html. 6.
Image Acquisition Control 6.7 Trigger Ready Signal 6.7.1 Trigger Ready Signal (All Models Except slA750-60fm) Note The information in this section applies to all camera models except the slA750-60fm fm/fc. For information about slA750-60fm cameras, see Section 6.7.2 on page 59. As described in the previous section, the cameras can operate in an “overlapped” acquisition fashion.
Image Acquisition Control Signal goes high at earliest safe moment to trigger acquisition N+1 Signal goes low when exposure for acquisition N+1 begins Signal goes high at earliest safe moment to trigger acquisition N+2 Signal goes low when exposure for acquisition N+2 begins TrigRdy Signal Image Acquisition N Exposure Readout Image Acquisition N+1 Exposure Readout Image Acquisition N+2 Exposure Readout Time Fig.
Image Acquisition Control 6.7.2 Trigger Ready Signal (slA750-60fm Only) Note The information in this section only applies to slA750-60fm cameras. For information about the other camera models, see Section 6.7.1 on page 57. As described in an earlier section, on these cameras the exposure for an image acquisition must not begin until readout of the previously acquired image has ended.
Image Acquisition Control You should be aware that if the Acquisition Frame Rate Abs parameter is enabled, the operation of the trigger ready signal will be influenced by the value of the parameter: If the value of the parameter is greater than zero but less than the maximum allowed, the trigger ready will go high at the rate specified by the parameter value. For example, if the parameter is set to 10, the trigger ready signal will go high 10 times per second.
Image Acquisition Control 6.8 Exposure Active Signal The camera’s “exposure active” (ExpAc) signal goes high when the exposure time for each image acquisition begins and goes low when the exposure time ends as shown in Figure 24. This signal can be used as a flash trigger and is also useful when you are operating a system where either the camera or the object being imaged is movable.
Image Acquisition Control 6.9 Acquisition Timing Chart Figure 25 shows a timing chart for image acquisition and transmission. The chart assumes that exposure is triggered with an ExTrig signal with rising edge activation and that the camera is set for programmable exposure mode. As Figure 25 shows, there is a slight delay between the rise of the ExTrig signal and the start of exposure.

Image Acquisition Control If Tb ≤ Tr, then Te = Tr + 250 µs If Tb > Tr, then Te = Tb + 250 µs You can determine the value of the Payload Size and Packet Size parameters from within your application software by using the pylon API. The following code snippet illustrates using the API to work with the parameter values: // Get payload size int64_t payloadSize = Camera.PayloadSize.GetValue(); // Set packet size Camera.PacketSizeSize.
Image Acquisition Control 6.10 Maximum Allowed Acquisition Frame Rate (All Models Except slA750-60fm) Note The information in this section applies to all camera models except the slA750-60fm. For information about slA750-60fm cameras, see Section 6.11 on page 70.
Image Acquisition Control Increasing the Maximum Allowed Frame Rate You may find that you would like to acquire frames at a rate higher than the maximum allowed with the camera’s current settings. In this case, you must first use the three formulas described below to determine what factor is restricting the maximum frame rate the most. Next, you must try to make that factor less restrictive: You will often find that the sensor readout time is most restrictive factor.
Image Acquisition Control Formula 2: Calculates the maximum frame rate based on the exposure time for the acquired frames: 1 Max. Frames/s = -------------------------------------------------------------------Exposure time in µs + C 3 Where the constant C3 depends on the camera model as shown in the table below: slA1000-30fm slA1390-17fm slA1600-14fm 136.47 µs 176.76 µs 181.
Image Acquisition Control Formula 2: 1 Max Frames/s = --------------------------------------------------2000 µs + 36.47 µs Max Frames/s = 491.0 frames/s Formula 3: 327100 Packets per frame = -------------------8192 Packets per frame = 39.9 (Round the result up to 40.) 1 Max. Frames/s = ------------------------------40 × 125 µs Max Frames/s = 200 frames/s Formula one returns the lowest value.
Image Acquisition Control maximum frame rate with the current camera settings. If you gradually decrease the setting for the Packet Size parameter, you will eventually find that the value of the Resulting Frame Rate Abs parameter will also decrease. If you are operating a single camera on your IEEE 1394b bus, you would ordinarily leave the Packet Size parameter set at the maximum.
Image Acquisition Control 6.11 Maximum Allowed Acquisition Frame Rate (slA750-60fm Only) Note The information in this section only applies to slA750-60fm cameras. For information about the other camera models, see Section 6.10 on page 65. In general, the maximum allowed acquisition frame rate can be limited by two factors: The sum of the exposure time plus the amount of time it takes to read the acquired image out of the imaging sensor and into the camera’s frame buffer.
Image Acquisition Control Increasing the Maximum Allowed Frame Rate You may find that you would like to acquire frames at a rate higher than the maximum allowed with the camera’s current settings. In this case, you must first use the two formulas described below to determine what factor is restricting the maximum frame rate the most. Next, you must try to make that factor less restrictive: You will often find that the sum of the exposure time plus the sensor readout time is the most restrictive factor.
Image Acquisition Control Formula 2: Calculates the maximum frame rate based on the number of packets needed to transmit a captured frame from the camera to your host PC via the IEEE 1394 bus: Value of the Payload Size Parameter Packets per frame = -------------------------------------------------------------------------------------------------Value of the Packet Size Parameter (round the result up to the nearest integer) 1 Max.
Image Acquisition Control 6.11.1 Effect of the Packet Size Setting on the Maximum Allowed Frame Rate After a camera acquires a frame, the image data is read out from the sensor into a buffer. Once the frame has been read out to the buffer, the data is packetized and transmitted across the IEEE 1394b bus to your host PC. A parameter called Packet Size determines the number of bytes of data that will be included in each packet transferred across the bus.

This section provides detailed information about the available pixel data formats. 7.1 Setting the Pixel Data Format The setting for the camera’s Pixel Format parameter determines the format of the pixel data that will be output from the camera. The available pixel formats depend on the camera model.
Pixel Data Formats 7.2 Pixel Data Formats 7.2.1 Mono 8 Format (Equivalent to DCAM Mono 8) When a monochrome camera is set for the Mono 8 pixel data format, it outputs 8 bits of brightness data per pixel. The table below describes how the pixel data for a received frame will be ordered in the image buffer in your PC when the camera is set for Mono8 output.
Pixel Data Formats With the camera set for Mono8, the pixel data output is 8 bit data of the “unsigned char” type. The available range of data values and the corresponding indicated signal levels are as shown in the table below.
Pixel Data Formats 7.2.2 Mono 16 Format (Equivalent to DCAM Mono 16) When a monochrome camera is set for the Mono16 pixel data format, it outputs 16 bits of brightness data per pixel with 12 bits effective. The 12 bits of effective pixel data fill from the least significant bit. The four unused most significant bits are filled with zeros. The table below describes how the pixel data for a received frame will be ordered in the image buffer in your PC when the camera is set for Mono16 output.
Pixel Data Formats When the camera is set for Mono 16, the pixel data output is 16 bit data of the “unsigned short (little endian)” type. The available range of data values and the corresponding indicated signal levels are as shown in the table below. Note that for 16 bit data, you might expect a value range from 0x0000 to 0xFFFF. However, with the camera set for Mono16 only 12 bits of the 16 bits transmitted are effective.
Pixel Data Formats 7.2.3 Mono 12 Packed Format When a monochrome camera is set for the Mono 12 Packed pixel data format, it outputs 12 bits of brightness data per pixel. Every three bytes transmitted by the camera contain data for two pixels. The table below describes how the pixel data for a received frame will be ordered in the image buffer in your PC when the camera is set for Mono 12 Packed output.
Pixel Data Formats When a monochrome camera is set for Mono 12 Packed, the pixel data output is 12 bit data of the “unsigned” type. The available range of data values and the corresponding indicated signal levels are as shown in the table below.
Pixel Data Formats 7.2.4 YUV 4:2:2 Packed Format (Equivalent to DCAM YUV 4:2:2) When a monochrome camera is set for the YUV 4:2:2 Packed pixel data format, the camera transmits Y, U, and V values in a fashion that mimics the output from a color camera set for YUV 4:2:2 Packed. The Y value transmitted for each pixel is an actual 8 bit brightness value similar to the pixel data transmitted when a monochrome camera is set for Mono 8. The U and V values transmitted will always be zero.
Pixel Data Formats Bm-3 U value for Pn-1 Bm-2 Y value for Pn-1 Bm-1 V Value for Pn-1 Bm Y value for Pn When the camera is set for YUV 4:2:2 Packed output, the pixel data output for the Y component is 8 bit data of the “unsigned char” type. The range of data values for the Y component and the corresponding indicated signal levels are shown below.
Pixel Data Formats Pn = the last pixel transmitted by the camera B0 = the first byte in the buffer Bm = the last byte in the buffer Byte Data B0 Y value for P0 B1 U value for P0 B2 Y value for P1 B3 V value for P0 B4 Y value for P2 B5 U value for P2 B6 Y value for P3 B7 V value for P2 B8 Y value for P4 B9 U value for P4 B10 Y value for P5 B11 V value for P4 • • • • • • Bm-7 Y value for Pn-3 Bm-6 U value for Pn-3 Bm-5 Y value for Pn-2 Bm-4 V value for Pn-3 Bm-3 Y val
Pixel Data Formats The pixel data output for the U component or the V component is 8 bit data of the “straight binary” type. The data values for a U or a V component will always be zero.
Pixel Data Formats 7.3 Pixel Transmission Sequence For each captured image, pixel data is transmitted from the camera in the following sequence: Row 0 Col 0, Row 0 Col 1, Row 0 Col 2 .. .. Row 0 Col m-2, Row 0 Col m-1, Row 0 Col m Row 1 Col 0, Row 1 Col 1, Row 1 Col 2 .. .. Row 1 Col m-2, Row 1 Col m-1, Row 1 Col m Row 2 Col 0, Row 2 Col 1, Row 2 Col 2 .. .. Row 2 Col m-2, Row 2 Col m-1, Row 2 Col m : : : : : : : : : : : : Row n-2 Col 0, Row n-2 Col 1, Row n-2 Col 2 .
I/O Control 8 I/O Control This section describes how to configure the camera’s physical input line and physical output line. It also provides information about monitoring the state of the input and output lines. For more detailed information about the physical and electrical characteristics of the input and output lines, see Section 5.4 on page 28. 8.1 Configuring the Input Line 8.1.
I/O Control 8.2 Configuring the Output Line 8.2.1 Assigning a Camera Output Signal to the Physical Output Line The camera is equipped with one physical output line designated as output line 1. You can use the camera’s output signal assignment capability to assign one of the camera’s standard output signals as the source signal for physical output line 1.
I/O Control 8.2.2 Setting the State of a User Settable Output Line As mentioned in the previous section, you can designate the camera’s output line as "user settable". If you have designated the output line as user settable, you can use camera parameters to set the state of the line. Setting the State of a User Settable Output Line To set the state of a user settable output line: Use the User Output Selector to select output line 1.
I/O Control You can set the Line Selector and the Line Inverter parameter value from within your application software by using the pylon API. The following code snippet illustrates using the API to set the selector and the parameter value: // Enable the inverter on output line 1 Camera.LineSelector.SetValue( LineSelector_Out1 ); Camera.LineInverter.SetValue( true ); For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide and API Reference.
I/O Control 8.2.4 Working with the Timer Signal The camera a timer output signal available called timer 1. The timer works as follows: A trigger source event occurs that starts the timer. A delay period begins to expire. When the delay expires, the timer signal goes high and a duration period begins to expire. When the duration period expires, the timer signal goes low. Duration Delay Trigger source event occurs Fig.
I/O Control 8.2.4.2 Setting the Timer Delay Time There are two ways to set the delay time for timer 1: by setting "raw" values or by setting an "absolute value". You can use whichever method you prefer to set the delay time. Setting the Delay Time with Raw Values When the delay time for timer 1 is set using "raw" values, the delay time will be determined by a combination of two elements. The first element is the value of the Timer Delay Raw parameter, and the second element is the Timer Delay Time Base.
I/O Control Setting the Delay Time with an Absolute Value You can also set the timer 1 delay by using an "absolute" value. This is accomplished by setting the Timer Delay Abs parameter. The units for setting this parameter are µs and the value can be set in increments of 1 µs. To set the delay for timer 1 using an absolute value: Use the Timer Selector to select timer 1. Set the value of the Timer Delay Abs parameter.
I/O Control 8.2.4.3 Setting the Timer Duration Time There are two ways to set the duration time for timer 1: by setting "raw" values or by setting an "absolute value". You can use whichever method you prefer to set the duration time. Setting the Duration Time with Raw Values When the duration time for timer 1 is set using "raw" values, the duration time will be determined by a combination of two elements.
I/O Control Setting the Timer Duration with an Absolute Value You can also set the timer 1 duration by using an "absolute" value. This is accomplished by setting the Timer Duration Abs parameter. The units for setting this parameter are µs and the value can be set in increments of 1 µs. To set the duration timer 1 using an absolute value: Use the Timer Selector to select timer 1. Set the value of the Timer Duration Abs parameter.
I/O Control 8.3 Checking the State of the I/O Lines 8.3.1 Checking the State of the Output Line You can determine the current state of the output line. To check the state of the output line: Use the Line Selector parameter to select output line 1. Read the value of the Line Status parameter to determine the current state of the line. A value of true means the line’s state is currently high and a value of false means the line’s state is currently low.
I/O Control the state of the associated line is currently low. If a bit is 1, it indicates that the state of the associated line is current high. Indicates output line 1 state Indicates input line 1 state Fig.

Standard Features 9 Standard Features This section provides detailed information about the standard features available on each camera. It also includes an explanation of their operation and the parameters associated with each feature. 9.1 Gain The camera’s gain setting is adjustable. As shown in Figure 28, increasing the gain increases the slope of the response curve for the camera. This results in a higher gray value output from the camera for a given amount of output from the imaging sensor.
Standard Features Setting the Gain (All Models Except slA750-60fm) Note The information in this section applies to all camera models except the slA750-60fm fm/fc. For information about slA750-60fm cameras, see the next section. The camera’s gain is determined by the value of the Gain Raw parameter. Gain Raw is adjusted on a decimal scale. The minimum decimal setting varies depending on the camera model (see Table 12).
Standard Features For gain raw settings from 110 to 511: 658 + Gain Raw Setting Gain dB = 20 × log 10 ⎛ ------------------------------------------------------------------⎞ – G c ⎝ 658 – Gain Raw Setting ⎠ For gain raw settings from 512 to 1023: Gain dB = (0.
Standard Features Setting the Gain (slA750-60fm Only) Note The information in this section only applies to slA750-60fm cameras. For information about the other camera models, see the previous section. The camera’s gain is determined by the value of the Gain Raw parameter. Gain Raw is adjusted on a decimal scale. The range for the Gain Raw parameter setting is from 0 to 22. To set the Gain Raw parameter value: Set the Gain Selector to Gain All. Set the Gain Raw parameter to your desired value.
Standard Features If you know the current decimal setting for the gain raw, you can use the following formula to calculate the dB of gain that will result from that setting: Gain Raw Setting Gain dB = 20 × log 10 ⎛ 1 + --------------------------------------------------⎞ ⎝ ⎠ 6 Example: Assume that you are working with an slA750-60fm camera that has a gain raw setting of 18. The gain is calculated as follows: 18 Gain dB = 20 × log 10 ⎛ 1 + --------⎞ ⎝ 6 ⎠ Gain dB = 12.
Standard Features 9.2 Black Level Adjusting the camera’s black level will result in an offset to the pixel values output by the camera. Increasing the black level setting will result in a positive offset in the digital values output for the pixels. Decreasing the black level setting will result in a negative offset in the digital values output for the pixels.
Standard Features 9.3 Digital Shift Note The information in this section applies to all camera models except the slA750-60fm. The digital shift feature lets you change the group of bits that is output from the ADC in the camera. Using the digital shift feature will effectively multiply the output of the camera by 2 times, 4 times, 8 times, or 16 times. The next two sections describe how the digital shift works when the camera is set for a 12 bit pixel format and when it is set for a 8 bit pixel format.
Standard Features only include values of 2, 4, 6, 8, 10, and so on. This absence of some gray values is commonly referred to as "missing codes". If the pixel values being output by the camera’s sensor are high enough to set bit 11 to 1, we recommend not using shift by 1. If you do nonetheless, all bits output from the camera will automatically be set to 1.
Standard Features Shift By 4 When the camera is set to shift by 4, the output from the camera will include bit 7 through bit 0 from the ADC along with 4 zeros as LSBs. ADC bit 11 bit 10 bit 9 The result of shifting 4 times is that the output of the camera is effectively multiplied by 16.
Standard Features If the pixel values being output by the camera’s sensor are high enough to set bit 11 to 1, we recommend not using shift by 1. If you do nonetheless, all bits ouput from the camera will automatically be set to 1. Therefore, you should only use the shift by 1 setting when your pixel readings with an 8 bit pixel format selected and with digital shift disabled are all less than 128.
Standard Features automatically be set to 1. Therefore, you should only use the multiply by 4 setting when your pixel readings with an 8 bit pixel format selected and with digital shift disabled are all less than 16. 9.3.3 Precautions When Using Digital Shift There are several checks and precautions that you must follow before using the digital shift feature.
Standard Features // Enable digital shift by 2 Camera.DigitalShift.SetValue( 2 ); For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide and API Reference. You can also use the Basler pylon Viewer application to easily set the parameters. For more information about the pylon Viewer, see Section 3.1 on page 17.
Standard Features 9.4 Area of Interest (AOI) The area of interest (AOI) feature lets you specify a portion of the sensor array and after each image is acquired, only the pixel information from the specified portion of the array is transmitted to the host PC. The area of interest is referenced to the top left corner of the sensor array. The top left corner is designated as column 0 and row 0 as shown in Figure 29.
Standard Features Setting the AOI The AOI is set by default to use the full resolution of the camera’s sensor. You can change the size and the position of the AOI by changing the value of the camera’s X Offset, Y Offset, Width, and Height parameters. The value of the X Offset parameter determines the starting column for the area of interest. The value of the Y Offset parameter determines the starting row for the area of interest.
Standard Features You can set the X Offset, Y Offset, Width, and Height parameter values from within your application software by using the pylon API. The following code snippets illustrate using the API to get the maximum allowed settings and the increments for the Width and Height parameters. They also illustrate setting the X Offset, Y Offset, Width, and Height parameter values int64_t widthMax = Camera.Width.GetMax( ); int64_t widhInc = Camera.Width.GetInc(); Camera.Width.SetValue( 200 ); Camera.
Standard Features 9.4.1 Changing AOI Parameters "On-the-Fly" Making AOI parameter changes “on-the-fly” means making the parameter changes while the camera is capturing images continuously. On-the-fly changes are only allowed for the parameters that determine the position of the AOI, i.e., the X Offset and Y Offset parameters. Changes to the AOI size are not allowed on-the-fly.
Standard Features 9.5 Reverse X The reverse X feature is a horizontal mirror image feature. When the reverse X feature is enabled, the pixel values for each line in a captured image will be swapped end-for-end about the line’s center. This means that for each line, the value of the first pixel in the line will be swapped with the value of the last pixel, the value of the second pixel in the line will be swapped with the value of the nextto-last pixel, and so on.
Standard Features Normal Image AOI Mirror Image AOI Fig. 31: Using an AOI with Reverse X Mirror Imaging Setting Reverse X You can enable or disable the reverse X feature by setting the ReverseX parameter value. You can set the parameter value from within your application software by using the pylon API. The following code snippet illustrates using the API to set the parameter value: // Enable reverse X Camera.ReverseX.
Standard Features 9.6 Disable Parameter Limits For each camera parameter, the allowed range of parameter values normally is limited. The factory limits are designed to ensure optimum camera operation and, in particular, good image quality. For special camera uses, however, it may be helpful to set parameter values outside of the factory limits. The disable parameter limits feature lets you disable the factory parameter limits for certain parameters.
Standard Features 9.7 Debouncer The debouncer feature aids in discriminating between valid and invalid input signals and only lets valid signals pass to the camera. The debouncer value specifies the minimum time that an input signal must remain high or remain low in order to be considered a valid input signal. We recommend setting the debouncer value so that it is slightly greater than the longest expected duration of an invalid signal.
Standard Features Setting the Debouncer The debouncer value is determined by the value of the Line Debouncer Time Abs parameter value. The parameter is set in microseconds and can be set in a range from 0 to approximately 1 s. To set the debouncer: Use the Line Selector to select input line1. Set the value of the Line Debouncer Time Abs parameter. You can set the Line Selector and the value of the Line Debouncer Abs parameter from within your application software by using the pylon API.
Standard Features 9.8 Trigger Delay The trigger delay feature lets you specify a delay (in microseconds) that will be applied between the receipt of a hardware trigger and it becoming effective. The trigger delay may be specified in the range from 0 to 10000000l µs (equivalent to 10 s). When the delay is set to 0 µs, no delay will be applied. The trigger delay will not operate when the camera is triggered by your application software and when the camera operates in continuous frame mode (free run).
Standard Features 9.9 Acquisition Status When controlling image acquisition with a software trigger you can use the acquisition staus feature to detemine when the camera is ready to be triggered for an image acquisition. Using this feature, you can avoid triggering the camera at a rate that exceeds the maximum allowed with the current camera settings. Note It is not possible to monitor the status of the Acquisition Start command.
Standard Features 9.10 Test Images All cameras include the ability to generate test images. Test images are used to check the camera’s basic functionality and its ability to transmit an image to the host PC. Test images can be used for service purposes and for failure diagnostics. For test images, the image is generated internally by the camera’s logic and does not use the optics, the imaging sensor, or the ADC. Five test images are available.
Standard Features Test Image 1 - Fixed Diagonal Gray Gradient (8 bit) The 8 bit fixed diagonal gray gradient test image is best suited for use when the camera is set for monochrome 8 bit output. The test image consists of fixed diagonal gray gradients ranging from 0 to 255. If the camera is set for 8 bit output and is operating at full resolution, test image one will look similar to Figure 33. The mathematical expression for this test image: Gray Value = [column number + row number] MOD 256 Fig.
Standard Features Test Image 3 - Moving Diagonal Gray Gradient (12 bit) The 12 bit moving diagonal gray gradient test image is similar to test image 2, but it is a 12 bit pattern. The image moves by one pixel from right to left whenever a new image acquisition is initiated. The test pattern uses a counter that increments by one for each new image acquisition.
Standard Features 9.11 Device Information Parameters Each camera includes a set of "device information" parameters. These parameters provide some basic information about the camera. The device information parameters include: Device Vendor Name (read only) - contains the name of the camera’s vendor. For scout cameras, this string will always indicate Basler as the vendor. Device Model Name (read only) - contains the model name of the camera, for example, slA1000-30fm.
Standard Features For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide and API Reference. You can also use the Basler pylon Viewer application to easily read the parameters and to read or write the Device ID. For more information about the pylon Viewer, see Section 3.1 on page 17.
Standard Features 9.12 Configuration Sets A configuration set is a group of values that contains all of the parameter settings needed to control the camera. There are three basic types of configuration sets: the active configuration set, the default configuration set, and user configuration sets. Active Configuration Set The active configuration set contains the camera’s current parameter settings and thus determines the camera’s performance, that is, what your image currently looks like.
Standard Features settings from the current active set to a reserved area in the camera’s non-volatile memory. A configuration set saved in the non-volatile memory is not lost when the camera is reset or switched off. There are three reserved areas in the camera’s non-volatile memory available for saving configuration sets. A configuration set saved in a reserved area is commonly referred to as a "user configuration set" or "user set" for short.
Standard Features 9.12.2 Selecting a Factory Setup as the Default Set When the camera is delivered, the Standard Factory Setup will be selected as the default configuration set. You can, however, select either one of the two factory setups to serve as the default set. To select which factory setup to serve as the default set: Set the Default Set Selector to the Standard Factory Setup or the High Gain Factory Setup.
Standard Features 9.12.3 Loading a Saved Set or the Default Set into the Active Set If you have saved a configuration set into the camera’s non-volatile memory, you can load the saved set from the camera’s non-volatile memory into the camera’s active set. When you do this, the loaded set overwrites the parameters in the active set. Since the settings in the active set control the current operation of the camera, the settings from the loaded set will now be controlling the camera.
Standard Features 9.12.4 Selecting the Startup Set You can select the default configuration set (i.e., whichever was selected as the default configuration set, either the Standard Factory Setup or the High Gain Factory Setup) or one of the user configuration sets stored in the camera’s non-volatile memory to be the "startup set". The configuration set that you designate as the startup set will be loaded into the active set whenever the camera starts up at power on or after a reset.

Using Multiple Cameras on a Single Bus and Managing Bandwidth 10 Using Multiple Cameras on a Single Bus and Managing Bandwidth This section includes information about using multiple cameras on a single IEEE 1394 bus. 10.1 Using Multiple Cameras Where All Devices are 1394b Most of the information included in this manual assumes that you have a single camera attached to your IEEE 1394b bus. But is it also quite common to attach more than one camera to a single bus.
Using Multiple Cameras on a Single Bus and Managing Bandwidth that we could have made the packet sizes smaller and thus the total byte load per cycle would be less than the maximum allowed. It is OK to make the total byte load smaller than the maximum, but not larger.
Using Multiple Cameras on a Single Bus and Managing Bandwidth 10.2 Using Multiple Cameras Where 1394a and 1394b Devices are Mixed The descriptions in the previous section assume that all of the devices on the bus are IEEE 1394b devices. If the bus has mixed IEEE 1394a devices and IEEE 1394b devices, determining how to share bandwidth between devices is a bit more difficult.
Using Multiple Cameras on a Single Bus and Managing Bandwidth PC PC 1394a Adapter 1394a Adapter 1394b Adapter 1394b Adapter 1394b Adapter S400 S400 S800 S800 S800 1394a Hub 1394b Hub S400 S800 1 2 3 1394a Camera Transmits at S400 1394b Camera Transmits at S400 1394b Camera Transmits at S800 4 5 6 7 1394a Camera Transmits at S400 1394b Camera Transmits at S400 1394a Camera Transmits at S400 1394b Camera Transmits at S800 Fig.
Using Multiple Cameras on a Single Bus and Managing Bandwidth You may be asking why we multiply the percentage for camera 1 by 4096 and the percentage for camera 2 by 8192. The reason is: During the part of the bus cycle when the packet for camera 1 is transmitted, the bus will operate at S400 speed. At S400, the maximum number of bytes that can be transmitted in a bus cycle is 4096. During the part of the bus cycle when the packet for camera 2 is transmitted, the bus will operate at S800 speed.
Using Multiple Cameras on a Single Bus and Managing Bandwidth 10.2.1 Recommended Packet Size When you change the value of the packet size setting on a camera, there is something that you must keep in mind. If you lower the packet size setting, the camera takes longer to transmit each acquired image. And if you lower the packet size enough, it will begin to restrict the maximum frame rate that the camera can achieve. A read only parameter called the Recommended Packet Size can help you avoid this problem.
