Method and apparatus for converting synchronizing signal for television cameras |
摘要 |
In a method and apparatus for converting a synchronizing signal received from a controller for controlling a TV camera into a new synchronizing signal, a single frame synchronizing pulse for every two field pulses is generated on the basis of at least a vertical drive signal of the synchronizing signal received from the controller. The new synchronizing pulse which has a level higher than the white level and lower than the black level of a composite video signal generated by the TV camera is injected into a video transmission line connected to the TV camera for synchronizing the latter on the basis of the injected synchronizing pulse.
