11. This section provides detailed information about the standard features available on each camera It also includes an explanation of the operation and the parameters associated with each feature 9 1 Gain The camera s gain setting is adjustable As shown in Figure 53 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 Decreasing the gain decreases the slope of the response curve and results in a lower gray value for a given amount of sensor output Increasing the gain is useful when at your brightest exposure a gray value lower than 255 in modes that output 8 bits per pixel or 4095 in modes that output 12 bits per pixels is reached For example if you found that at your brightest exposure the gray values output by the camera were no higher than 127 in an 8 bit mode you could increase the Gray Values 4095 255 12 bit 8 bit 12d 6 dB 0 dB 0 25 50 100 Sensor Output Signal Fig 53 Gain in dB gain to 6 dB an amplification factor of 2 and thus reach gray values of 254 Basler scout 137 Standard Features Setting the Gain All Models Except scA750 60 Note The information in this section applies to all camera models except the scA750 60 fm fc For information about scA750 60 cameras see the next section Note Gain can not only be manually set se

22. For information about scA750 60 cameras see Section 6 7 2 on page 82 As described in the previous section the cameras can operate in an overlapped acquisition fashion When the camera is operated in this manner it is especially important that the exposure time of a new image acquisition not start until exposure of the previously acquired image is complete and the exposure time of a new image acquisition not end until readout of the previously acquired image is complete The camera supplies a Trigger Ready TrigRdy output signal you can use to ensure that these conditions are met when you are using a hardware trigger signal to trigger image acquisition When you are acquiring images the camera automatically calculates the earliest moment that it is safe to trigger each new acquisition The trigger ready signal will go high when it is safe to trigger an acquisition will go low when the acquisition has started and will go high again when it is safe to trigger the next acquisition see Figure 45 The camera calculates the rise of the trigger ready signal based on the current exposure time parameter setting the current size of the area of interest and the time it will take to readout the captured pixel values from the sensor The trigger ready signal is especially useful if you want to run the camera at the maximum acquisition frame capture rate for the current conditions If you monitor the trigger ready signal and you trigger

During a single bus cycle a device operating at S800 speed can transmit a single packet of up to 8192 bytes Alternatively several devices operating at S800 speed can transmit packets during a single bus cycle as long as the sum of the bytes in the packets is 8192 bytes or less The next thing that we must consider in a bus that has mixed 1394a and 1394b devices is the speed at which each device will transmit A 1394a device will always be capable of transmitting at S400 speed on a mixed 1394a 1394b bus The 1394a device can transmit at slower speeds but we are assuming that you always want to transmit at the fastest speed A 1394b device will transmit at S800 speed if all of the devices in its path to the host PC including the adapter card in the PC are 1394b devices If the path to the PC passes through any 1394a device then the 1394b device will transmit at S400 speed Figure 70 illustrates some situations where 1394a devices and 1394b devices are mixed ona single bus If you look at the figure you will notice Camera 1 will transmit image data at S400 speed This is simply because the camera itself is a 1394a device and S400 is the maximum speed for 1394a devices Camera 2 will transmit image data at S400 speed The camera is a 1394b device which means that it is capable of S800 speed But the camera s path to the host PC passes through a 1394a adapter so this limits the camera s actual maximum speed to S400 Camera 3 will t

51. at location 5 is not used The number at location 6 in the table represents the mapped 10 bit value that will be used when the sensor reports that a pixel has a value of 6 And so on As you can see the table does not include a mapped 10 bit output value for every pixel value that the sensor can report So what does the camera do when the sensor reports a pixel value that is between two values that have a mapped 10 bit output In this case the camera performs a straight line interpolation between the two nearest neighbors to determine the value that it should use For example assume that the sensor reports a pixel value of 5 In this case the camera would perform an interpolation between the values at location 4 and location 6 in the table The result of the interpolation would be used as the mapped 10 bit value Another thing to keep in mind about the table is that location 1022 is the last location that will have a mapped 10 bit value associated with it If the sensor reports a pixel value of 1023 the camera will not be able to perform an interpolation In this case the camera simply uses the mapped 10 bit value from location 1022 in the table The advantage of the luminance lookup table feature is that it allows a user to customize the response curve of the camera The graphs on the next page show the effect of two typical lookup tables The first graph is for a lookup table where the values are arranged so that the output of the Basler

The trigger width exposure mode is not available on scA750 60 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 For example assume that you will be using trigger width exposure and that you intend to use the ExTrig signal to vary the exposure time in a range from 3000 us to 5500 us In this case you would use the exposure setting to set the exposure time to 3000 us If you are using the trigger width exposure mode and the camera is operating with overlapped exposures there is something you must keep in mind If the action of the ExTrig signal would end the current exposure while readout of the previously acquired image is still taking place the camera will automatically continue the exposure until readout of the previous image is complete This situation is illustrated Figure 39 for rising edge operation On the first cycle of the ExTrig signal shown in the figure the signal rises and falls while readout is taking place Normally you would expect exposure to take place only when the ExTrig signal is high But since the signal falls while the previous frame is still reading out the camera automatically exte
