This delay is normally counted as a number of video lines. In case of interlaced scanning, and for some special tap structures, the counting unit is the video half-line.

This parameter applies to area-scan cameras delivering a separate vertical synchronization pulse used by the frame grabber to monitor the camera timing (digital synchronization mode).

If this pulse is not available, the vertical synchronization embedded in the composite video signal is used instead (analog synchronization mode). In this case, the VCsyncAft_Ln parameter is significant.

The delay is counted from to the leading edge of the vertical synchronization pulse delivered by the camera.
