Video Area
The video image area is composed of pixels and lines of video. The
total video area is the complete set of horizontal and vertical input
lines from which you extract the active video area and the frame
within the active video area that you want to digitize. The total video
area includes all parts of the signal, including nonvisual portions
such as horizontal and vertical blanking information. (Blanking
information is the data not included in the active video area; it
contains sync and other information.)
The total video area is as wide as the total pixels per line (the entire
area between two consecutive horizontal sync signals) and as tall as
the total lines per field (the entire area between two consecutive
vertical sync signals).
The total pixels per line can be calculated as follows:
The total lines per field can be calculated as follows:
For area-scan operations only, you can use software to define the total
video area for the DT3152-LS frame grabber board.
