Abstract
PURPOSE: To enable to add new color and to synthesize two video signals with varied amplitude, by forming a given circuit.
CONSTITUTION: The video signal A of TV camera 4 which is controlled with the signal from the picture deformation control circuit 1 and driven with the synchronizing pulse from the synchronizing signal generating circuit 2 is inputted to the addition circuit 6 and the carrier chrominance signal from the color signal generation circuit 3 is superimposed on the picture signal A at the addition circuit 6. This signal is fed to the synthesizing circuit 9, to which the composite video signal B is inputted from another video signal source 11. Further, the synthesizing circuit 9 selects the video signals A and B with the control signal of th control signal generating circuit 8 and feeds it to the output terminal 10. Further, the signal of the picture deformation control circuit 1 changes the amplitude of the signal A to enable synthesizing with different size and the output of the color signal generating circuit 2 enables new color added for synthesis.
