3.5.2Internal Shutter Speed Control
The video signal starts with internal VD. The camera operates the reset and shutter in the same way as the external pulse width control mode. When the external VINIT pulse is applied, internal VD is latched to HD and the internal VD is delayed to set up the shutter speed period. The shutter speed is controlled by the dial switch from “1” to “8.” Video output timing starts right after the internal VD and single shots, FDV is output at the internal VD timing.
