PHASE CONDITIONS OF EXTERNAL

SYNCHRONIZATION

External synchronization for each mode

•

For normal video/normal shutter

Continuous HD/VD signal (should conform to EIA and CCIR frequencies in the timing shown in the figure below.)

•

For Restart Reset (RR)/external trigger shutter

Continuous HD signal. The phase between VD (reset) and HD signals is as specified in the figure below in any

timing.

Phase conditions

The phase relation between external input HD and VD signals should be set as shown below with respect to the

specified center phase.

there is no VD signal delay at VS external synchronization mode.
