Members
| Member name | Value | Description | |
|---|---|---|---|
| InternalComposite | 0 | Sync is generated in the frame grabber, and is sent to the camera on the H-sync wire. | |
| InternalDrive | 1 | Sync is generated in the frame grabber, and is sent to the camera as logic levels on the H- and V-wires. | |
| ExternalPLLComposite | 2 | The frame grabber derives sync from the camera using the composite video/sync signal. The pixel clock used to acquire samples is derived on the frame grabber using phase locked loop circuitry and the horizontal sync signal from the camera. | |
| ExternalPLLSync | 3 | The frame grabber derives sync from the camera using the negative-going analog sync signals coming from the camera on the H- and V-wires. The pixel clock is regenerated on the frame grabber using the phase locked loop. | |
| ExternalPLLDrive | 4 | The frame grabber derives sync from the camera using the positive-going logic drive signals coming from the camera on the H- and V-wires. The pixel clock is regenerated on the frame grabber using the phase locked loop circuitry. | |
| ExternalPixelSync | 5 | The frame grabber derives sync from the camera using the negative-going analog sync signals coming from the camera on the H- and V-wires. The pixel clock coming from the camera is used directly to sample the image. | |
| ExternalPixelDrive | 6 | The frame grabber derives sync from the camera using the positive-going logic drive signals coming from the camera on the H- and V- wires. The pixel clock coming from the camera is used directly to sample the image. |
Remarks
Enumeration for camera synchronization models used by the SyncModel property which is supported only on the MVS-8100M.
For other frame grabbers that use CCF-based video formats, the sync model is described in the format name.
To learn more about synchronization models, see the topic Synchronization Models.
