Line Acquisition Modes
Basler sprint Mono Cameras 43
To better understand the concept of dual line acquisition, consider the example that is illustrated in
Figure 16 through Figure 19. This example describes dual line acquisition (line A first) when an
ExSync signal and the programmable exposure control mode are used. The example looks at four
contiguous "points" on an object moving past the camera. Each point represents the area on the
object that will be captured by one line in the sensor when a line acquisition is performed. As you
look at the figures, notice that on the ExSync cycles where an acquisition is performed, line A will
capture one point on the object and line B will capture a different point on the object. Also notice
that on these cycles, the pixel data for line A will be transmitted while the pixel data for line B will be
buffered. On the ExSync cycles where acquisition is not performed, the buffered pixel data for line
B will be transmitted.
