PURPOSE:To establish synchronization among plural cameras without an external synchronizing signal generator, by taking out the external synchronizing signal from the first TV camera which is reference of synchronization and by applying this signal to the second TV camera. CONSTITUTION:The first vertical driving (VD) signal output terminal 11 and the first horizontal driving (HD) signal output terminal 12 of the first TV camera 10 which is reference of synchronization are connected to VD signal input terminal 21 and HD signal input terminal 22 of the second TV camera 20 whose synchronization is established from the external. In this system, synchronization can be established cheaply because it is unnecessary to provide an external synchronizing signal generator. |
