Vertical Partial Scan Mode
□
One partial area can be set by serial commands.
□
Total line count per frame = V blanking lines (fixed to 25H)
＋
Partial effective lines
Note that partial effective line counts have to be between “2” and “2048”.
□
Frame rate = 1 / (Total line count per frame x Time for 1 line)
□
Time for 1 line of each mode

□
The line count and the start position at partial scan setting can be set in increment of 2 lines.
□
At vertical partial scan setting, the gain(AGC) and the shutter(AE) set to OFF beforehand.
□
At vertical partial scan setting, the binarization and the shading correction set to OFF beforehand.
□
At vertical partial scan setting, the effective line count becomes maximum for the manual shutter
setting value.
□
At vertical partial scan setting, the coordinates of a cursor are set to (0, 0).
□
There are 2 methods for partial scan setting; one is to use only address 50 and the other is to
use addresses 51 and 52. Same operation can be performed whichever used.
However, note that the above setting is reflected when 1 is written in address 54.
□
Write 0 in address 54 when the partial scan turns OFF.
