TM-6760 Series Progressive Scan Shutter Cameras
Operation
FIGURE 8. Pulse Width Async Shutter Timing
3.6.2 Internal Shutter Speed Control
The video signal starts with internal VINIT. 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 VINIT is
latched to H
D and the internal VINIT 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 VINIT
and single shots, FDV is output at the internal VINIT timing.
