This parameter is expressed as a number of video lines.

The total number of lines includes active lines and blanking lines. This is a feature of the video standard the camera may comply to.

In case of interlaced scanning, Vtotal_Ln represents the number of lines for both fields altogether. This is equivalent to the number of half-lines per field.

In some cases of dual-tap structure, Vtotal_Ln represents the number of lines for both channels altogether.

This parameter is used to characterize area-scan cameras. It is meaningless for line-scan cameras.

When FvalMode=FC, Vtotal_Ln specifies the maximum number of lines that can be acquired.
