Abstract

PURPOSE:To switch plural TV cameras, and to obtain a special effect picture, by a simple constitution, by connecting a switching circuit provided with a desired special effect providing function, between one set of camera head part and a camera control part. CONSTITUTION:On the input side of a camera control part 13, plural camera head connecting terminals 25-1-25-n are provided, and between these connecting terminals and a signal processing circuit 23, a switching circuit 16 is installed so as to attachable and detachable. Each terminal 25-1-25-n applies signals from camera head parts 14-1-14-n to the circuit 16, and also sends out a synchronizing signal from a synchronizing signal generator 12 to the camera head part. The circuit 16 has a function for selecting one or more of the terminals 25-1- 25-n, and switching and connecting the circuit 23, and consisting of combination of an electronic switch, an amplifier, etc. When a gain controllable mixing amplifier for controlling a level of this switching output is added in the circuit 16, a special effect picture can be obtained.
