The max value of vertical partial scan starting position is limited with the formula below since vertical partial scan output
line has priority.
The max value of vertical partial scan starting position
=480(The max value of vertical partial scan output line) –
Vertical partial scan output lines
(Ex.) When 400 is set as vertical partial scan output lines, the max value of vertical partial scan starting position will be
480-400 = 80.
If vertical partial scan starting position is set to 90 with this time, vertical partial scan output line has priority so that vertical
partial scan starting position shall be limited to 80.
※
At manual partial scan mode, manual shutter value to be set shall meet the following conditions.
The set manual shutter lines
≦
Vertical partial scan output lines
If the condition above is not met, shutter lines to be set will be the same number as vertical partial scan output lines.
