5.1.3 Trigger Position Reset/Restart Shutter Mode

The shutter trigger pulse (TRIG) needs to synchronize with Reset-Restart (EXT VD) pulse. It should be

2 lines or more in width. The leading edge of TRIG pulse produces DSUB (discharge) pulse and starts

the exposure. The transfer (read-out) occurs at the 11th line after EXT VD pulse is fed. A full picture

ﬁeld can be obtained in every ﬁeld. The TRIG must be wider than one line.
