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.
