・
The max value of horizontl partial scan starting position is limited with the formula below since output pixel number has priority.
The max value of horizontal partial scan starting position =2048 (sensor effective pixels) – output pixel number
Output pixel number = 640 + (horizontal partial scan output pixel set value x 10)
(Ex.) When 10 is set as horizontal partial scan output pixel number, the max value of horizontal partial scan starting position will
be 2048 – (640 + 10 x10) = 1308.
If horizontal partial scan starting position is set to 1318 with this time, output pixel number has priority so that horizontal
partial scan starting position shall be limited to 1308.
