Abstract

PURPOSE:To improve instant recording and playback operation and to enable long time playback of a still picture, by assembling the still picture memory in the picture synthesizer. CONSTITUTION:The video signal A from the black-and-white camera 3 is input to the addition circuit 10 through the blanking rejection circuit 9. The addition circuit 10 superimposes the carrier chrominance signal fed from the chroma signal generating circuit 8 on the picture signal A. This superimposed video signal A is fed to one input terminal (b) of the synthesis circuit 11. Further, composite video signal fed from the picture memory 2 is input to another input terminal (a) of the synthesis circuit 11. In the synthesis circuit 11, the amplitude of two types of signals fed to (a), (b) is controlled with the control signal given from the control signal generating circuit 13 and it is fed to the monitor 5. Further, the picture memory 2 is incorporated with the device recording one frame and reproducing it.
