Video frame grabber comprising analog video signals analysis system |
摘要 |
In a video frame grabber for digitizing analog video signals which have a pure analog video signal component and a synchronisation signal component, the synchronisation signals are digitized along with the pure analog video signals. Video gain and offset, sync gain, and sync threshold can be adjusted electronically. A variable time delay can be imposed on the sampling clock signals and on horizontal reference signals. Optimal values can be determined for the various parameters.
