Parameter Description
An active line is, by definition, a video line where useful visual information can appear. Blanking lines take no part in the count of active lines.
In case of interlaced scanning, Vactive_Ln represents the number of active lines for both fields altogether. This is equivalent to the number of active half-lines per field.
In some cases of dual-tap structure, Vactive_Ln represents the number of active lines for both channels altogether.
This parameter is a measure of the height of the camera active window.
It is used to characterize area-scan cameras. It is meaningless for line-scan cameras.
