• Basler Vision Technologies Sprint Series, Exposure Start and Exposure Time Control 78 Basler sprint Mono Cameras Segment 1 includes 64 of the pixels in the AOI and segment 2 includes 192 of the pixels in the AOI. The Max Seg AOI Pixels in this situation would be 192 (because segment 2 contains the largest part of the AOI and the number of AOI pixels in segment 2 is 192). Fig. 33: AOI Falling Across Segments Note If you have set an AOI to extend over two adjacent sensor segments and to use each sensor segment only partially, the Max Seg AOI Pixels will be smallest when the AOI is evenly divided across the two segments (i.e., each segment contains the same number of AOI pix

• Basler Vision Technologies Sprint Series, Specifications, Requirements, and Precautions 20 Basler sprint Mono Cameras 1.7 Precautions Applying Incorrect Camera Power Can Damage the Camera The nominal voltage for the camera power is 12 VDC (± 10%). We do not recommend applying a voltage less than 10.8 VDC or greater than 13.2 VDC. The camera has camera power undervoltage protection that is triggered if the voltage drops below 10.5 VDC. It also has camera power overvoltage protection up to 25 VDC. See Section 6.8 on page 145 for more detailed information about camera power undervoltage and overvoltage protection. Applying a camera power voltage greater than 25 VDC can seriously damage the camera. CAUTION Ma

The Camera Link clock is used to time the transmission of acquired pixel data. As shown in Table 8, the Camera Link clock speed is fixed at 40 MHz on some camera models and can be set to either 80 MHz or to 40 MHz on some models. The default on cameras with a settable clock speed is 80 MHz. Setting the Camera Link Clock Speed On camera models with a s

For example, the gain control and status register has two fields that can be used to set the camera’s gain (see Section 6.1 on page 115). By writing values to fields in the control registers, you configure the camera and control how it operates. By reading values from fi

So with the current camera settings, the maximum allowed line rate would be 175438 lines per second. The minimum allowed line period in this case would be: Min Line Period = 0.0000057 = 5.7 µs 4.3.3 Increasing the Maximum Allowed Line Rate You may find that you would like to acquire lines at a rate higher than the maximum allowed with your current camera settings. If this is the case, you must first use the four formulas described on page 74 to determine which factor is restricting the maximum line rat

• Basler Vision Technologies Sprint Series, Features Basler sprint Mono Cameras 121 6.3 Shading Correction In theory, when a digital camera captures an image of a uniform object, the pixel values output from the camera should be uniform. In practice, however, variations in optics and lighting and small variations in the sensor’s performance can cause the camera output to be non-uniform even when it is capturing images of a uniform object. The camera is equipped with a shading correction feature that allows it to correct the captured image for variations caused by optics, lighting, and se
