(1) Multiplexed vertical drive signal (VD2)
(2) Synchronization is performed on the basis of the power supply frequency.
(3) Internal synchronization (INT) (default)
Input of a multiplexed vertical drive signal (VD2) automatically switches to the VD2 synchronization even if the camera is set to
other than the VD2 synchronization method.
When other than the VD2 synchronization is selected, either the power supply synchronization or internal synchronization can be
selected.
