Abstract:
A video signal processing apparatus has an input terminal receiving a real moving picture video signal, for example, from a video camera, a memory for storing at least one field of the real moving picture video signal so as to form a still picture video signal, a key signal generator which may be constituted by an additional memory storing data characteristic of a key picture, and a circuit responsive to reading of the data stored in the additional memory for switching between the real moving picture video signal and the still picture video signal and thereby forming a composite video signal therefrom.
