Line Acquisition Modes70 Basler sprint Color Cameras3.4.1 Enhanced Raw - Line A First (B Delayed) LineAcquisition ModeThe Enhanced Raw - Line A First (B Delayed) line acquisition mode is analogous to the EnhancedRaw - Line B First (A Delayed) line acquisition mode (see Section 3.4.2 on page 82), with the rolesof lines A and B interchanged.In the Enhanced Raw - Line A First line acquisition mode, the two lines which include pixel data fromthe same area of the object, are transmitted immediately one after the other: The pixel data for lineA will be transmitted first, followed by the related pixel data for line B, which are transmitted on thenext clock cycle. In this way, pairs of related lines are created with both lines imaging the same areaof the object.When using the Enhanced Raw - Line A First (B Delayed) line acquisition mode, the object beingimaged should cross line A first and line B second (the image of the object will cross line B first andline A second as is apparent from Figure 37 through Figure 42).After having enabled the Enhanced Raw - Line A First (B Delayed) line acquisition mode, thefollowing will occur in a sequence of ExSync cycles: The first cycle of the ExSync signal will: trigger the start of image acquisition (i.e., exposure) on both lines in the sensor. Theexposure time you are using will apply to both lines. time the start of pixel data readout for both lines. time the start of transmission of line A pixel data. This is data for which no related data fromline B will become available. The data is therefore not useful. The values from line B are held in a buffer in the camera. Their output will be delayed untilthe fourth cycle of the ExSync signal. The second cycle of the ExSync signal will: time the start of transmission of line B pixel data. This is data that was stored before theEnhanced Raw - Line A First (B Delayed) line acquisition mode was enabled. The data istherefore not useful.No exposure will occur. The third cycle of the ExSync signal will: trigger the start of image acquisition (i.e., exposure) on both lines in the sensor. Theexposure time you are using will apply to both lines. time the start of pixel data readout for both lines. time the start of transmission of line A pixel data. The values from line B are held in a buffer in the camera. Their output will be delayed untilthe sixth cycle of the ExSync signal. The fourth cycle of the ExSync signal will: time the start of transmission of line B pixel data. This data was acquired on the first ExSynccycle and relates to the data from line A that was transmitted on the preceding ExSynccycle (i.e. the third cycle).No exposure will occur. The fifth cycle of the ExSync signal will: trigger the start of image acquisition (i.e., exposure) on both lines in the sensor. The
