Internal/External synchronization
Except the internal sync (provided by internal electronics), the camera can accept
external sync information as well. Three types of sync signals are possible:
- HD/VD (horizontal drive/vertical drive) signals
- The camera determines whether to operate in interlaced or noninterlaced
modes from the phase relation between HD and VD (see Scanning system).
- The camera determines whether to operate in interlaced or noninterlaced
- VBS (composite video signal)
- The camera is synchronized by supplying a composite video signal (for
example from another image sensor).
- The camera is synchronized by supplying a composite video signal (for
- SYNC (composite sync signal)
- Synchronization is performed by means of composite sync input signal.
The unit switches automatically between all sync types mentioned above. If no sync
signal is input, it operates with internal sync and 2:1 interlace mode.
